Simplex 3637 L down tube gear cable guide, hailing from France and in production during the 1970s (yet still new & unused after all this time!). Made from steel/plastic and weighing in at 26 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.
If you're taking part in L'Eroica or any other vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong cable guide!
OVERVIEW
TECHNICAL INFO
Number of Cables - the number of cables the guide is designed to accept.
Guide Type - some setups require specific guides for the derailleurs to operate correctly. Tunnels simply act as a channel to guide the cable whereas stops create an end point for the cable housing, giving the cable the leverage it needs. Bar control stops are required when using handlebar shifters if your frame doesn't have any guides or braze-ons.
Tube Diameter - most steel (and early lugged aluminium) frames will have a down tube of 28.0 mm - 28.6 mm, this was standard for a long time but there are 'oversized' steel and aluminium tubes that have a diameter of 31.8, 34.9 and even 38.1 mm.

Made from aluminium and weighing in at 25 grams (for the pair). A fine choice for keeping your classic bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Back Shape - most adjustable stops have curved backs, designed to fit steel frames with standard braze-ons and a down tube diameter of around 28.6 mm (1 1/8"). Some oversized frames have flat plates at the base, these require stops with flat backs.
Boss Thread Size - most frames will have M5 (5mm) threads on the shifter bosses as this has been standard for a long time. However, if you're converting an older frame with Shimano bosses (M4.5 / 4.5 mm threads) or French bosses (5 x 1 mm threads) you'll need to use different bolts to fix the adjusters to your frame.

Shimano front hub, hailing from Japan and dating back to 1988 (yet still new & unused after all this time!). Made from aluminium/steel and weighing in at 145 grams - incredibly lightweight for a front hub at that time. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Spoke Drilling - the number of holes for the spokes, your wheel rim needs to match the hub exactly.
Spacing (O.L.D.) - the width of the hub measured at its widest point, from the outside of the locking end nuts (O.L.D. = Over Locknut Dimension), not including the hub axle. This measurement needs to match the inside of your fork's dropouts. Steel forks can be stretched or squeezed a few mm but it's always best to avoid this if possible, aluminium or carbon forks should never be stretched.

Time MID 57 pedals, hailing from France and in production during the 1990s (yet still new & unused after all this time!). Made from plastic/steel and weighing in at 390 grams - pretty lightweight for clipless pedals at that time. A fine choice for keeping your classic bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Cleat System - the cleat the pedals were designed to fit. The brand of cleats doesn't have to match, as long as they were designed for the same system.
Pedal Threads - this must match the thread on your cranks. Sometimes it's stamped on the end of the crank arm, but most bikes use a standard thread of 9/16” x 20 tpi. The exceptions being older French bikes, bikes with cheaper one-piece type chainsets and Shimano’s Dyna Drive system (easily identifiable as the pedal holes are about an inch wide!).
£48.75 £65.00
Shimano Light Action pedals, hailing from Japan and in production during the 1990s (yet still new & unused after all this time!). Made from steel/aluminium and weighing in at 339 grams - pretty lightweight for pedals at that time. A fine choice for keeping your classic bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Pedal Type - this is just a guide to give you an idea of the pedal type, but any pedal can technically be used for any purpose. Track pedals are designed without the pointed 'quill' for safety though, so it's best to only use track pedals for this purpose. Most track pedals, along with quill & aero road pedals are designed to be used with toe clips & straps for best performance.
Pedal Threads - this must match the thread on your cranks. Sometimes it's stamped on the end of the crank arm, but most bikes use a standard thread of 9/16” x 20 tpi. The exceptions being older French bikes, bikes with cheaper one-piece type chainsets and Shimano’s Dyna Drive system (easily identifiable as the pedal holes are about an inch wide!).

OVERVIEW
TECHNICAL INFO
Crank Bolt Type - 15 mm hex bolts used to be standard but some older TA, Stronglight and Zeus cranks used a larger 16 mm bolt, plus a few Japanese makers used a smaller 14 mm hex head. Allen key types were introduced in the 1980s and some are self-extracting, which means the crank removes itself when you undo the bolts.
Crank Bolt Thread - All square taper bottom brackets have a standard M8 x 1 mm thread, the only different thread types you’ll find on crank bolts are the much larger M12 & M15 bolts that are specifically for Octalink and ISIS bottom brackets.

OVERVIEW
TECHNICAL INFO
Chainring Count - the number of chainrings the bolts are designed to fit, this must be the same as the number of chainrings you are using.
Crank Type - Most cranks require the standard 5-bolt sets that consist of 5 bolts with backs that slot into the rear of the crank spider, there are also some less common cranks with 3 arms that require the 3-arm chainring bolts. Specialites T.A. 'Professionel 5 Vis' and Stronglight '49D' type cranks require special 50.4 BCD chainring bolts that are specific to these crank designs.
Mount Type - most bolts simply fix the chainring to the crank, but some cranks require bolts to fix one chainring to another.
Back Nut Length (Excluding Head) - the more chainrings your crank has the longer the bolts and nuts need to be. We exclude the head part from the measurement (the bit that often sits recessed in back of the chainring).

OVERVIEW
TECHNICAL INFO
Tooth Count - the number of teeth on the chainring, the higher the number the harder the gear.
Between Adjacent Bolt Holes - the measurement from the centre of any bolt hole to the centre of an adjacent one, if this measurement is the same as that of your crankset and the bolt count is the same then the chainring should fit.
BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is the technical way to determine whether the chainring fits your crankset. To calculate, multiply the distance between adjacent holes (in mm) by 1.709 (you’ll likely need to round the resulting number up or down a little).
Chainset Type - the number of rings on the chainset it was designed to be used with. Technically this doesn't have to be adhered to, although with higher speed setups it is recommended for accurate and responsive front shifting.
Bolt Count - the number of bolts securing the chainring to the chainset. As with the BCD, this must be the same as your chainset.
Chain Width - 3/32” is the standard width for double and triple chainsets, wherease 1/8” chainrings are only found on single ring chainsets, generally for track / singlespeed use and can only be used with a wide 1/8" chain.
Intended Speed - the number of cogs at the back the chainring was designed to be used with. We refer to it as ‘intended’ speed as most double and triple chainsets will actually work with different speeds than originally intended, but the further away you get from the intended speed the more likely you are to experience minor setup issues. The exception being some chainrings intended for 10 speed use or higher, with these it’s better to stick to the intended speed.

OVERVIEW
TECHNICAL INFO
Width - the total width at its widest point, from end to end, rounded to the nearest 5 mm.
Clamp Size - this should match the internal diameter of your handlebar stem clamp, and should be as close as possible to ensure a good and safe fit.
Grip Diameter - the outside diameter of the area where handlebar grips are fitted, this determines not only what grips will fit but brake levers too so it's important to check if you have a specific setup in mind.
Rise/Drop - we measure this at the end of the bars, from the centre point of the clamp area to the centre of the end. This measurent can change when the bar is rotated so there is a bit of tolerance here, please use this as an approximate measurement only.

OVERVIEW
**This is a guide based on traditional toe clip sizing for cycling shoes of the time, if you ride with chunkier shoes then we'd recommend going for a larger size. Please use this as a guide only and if possible use the length measurement provided to compare with toe clips you know fit well.
TECHNICAL INFO
Pedal Fixing - 'standard' toe clips fix to the front of the pedals, most will be of this type and work with both quill & platform pedals providing they have mounting holes in the correct place. There are also 'aero' ones that attach to the top, and side fixing versions too. 'Wide platform' fixings are similar to standard ones but the fixing holes are almost 3 inches apart.
Toe Strap Type - most toe clips are designed to accept a single toe strap, but there are some less common ones that allow two toe straps to be fitted.
Length - this is measured from the fixing end to the toe end at the most extreme points, the same way the manufacturers measure and we use this to recommend the fit if there's no size stamped on them. All length measurements are rounded to the nearest 0.5 cm.
Distance Between Fixing Bolts - we measure this distance from the centre of one hole to the next (ctc), this usually only needs to be close, not exact, providing the holes on the toe clips are oblong shaped to allow a decent amount of wiggle room (most toe clips are made this way).
£41.25 £55.00

Distance Between Fixing Bolts - we measure this distance from the centre of one hole to the next (ctc), this usually only needs to be close, not exact, providing the holes on the toe clips are oblong shaped to allow a decent amount of wiggle room (most toe clips are made this way).

OVERVIEW
**This is a guide based on traditional toe clip sizing for cycling shoes of the time, if you ride with chunkier shoes then we'd recommend going for a larger size. Please use this as a guide only and if possible use the length measurement provided to compare with toe clips you know fit well.
TECHNICAL INFO
Pedal Fixing - 'standard' toe clips fix to the front of the pedals, most will be of this type and work with both quill & platform pedals providing they have mounting holes in the correct place. There are also 'aero' ones that attach to the top, and side fixing versions too. 'Wide platform' fixings are similar to standard ones but the fixing holes are almost 3 inches apart.
Toe Strap Type - most toe clips are designed to accept a single toe strap, but there are some less common ones that allow two toe straps to be fitted.

OVERVIEW
TECHNICAL INFO
Seatpost Diameter - this needs to match the internal diameter of your frame’s seat tube closely, it should be possible to insert the seatpost without force but the fit should be tight enough so it doesn’t just drop in, with no play once inserted. If you have a post that fits the measurement should be stamped somewhere near the bottom, if not you’ll need to measure with a caliper or seatpost sizing tool as the sizes go up in 0.2 mm increments.
Length (Top to Bottom) - measured from the top to the bottom of the seatpost. Normally there’s a mark to tell you how much of the seatpost needs to be inserted in the frame, however this isn’t always the case so we’d recommend allowing a minimum of 6 cm.

NB: If mounted in the photos this is for illustrative purpose only, any wheels or rims shown are not included.OVERVIEW
TECHNICAL INFO
Size - this is the manufacturer’s sizing and must match the size or your wheel. This can be confusing as tyres have had different sizing systems over the years, and there are many (sometimes conflicting) sizes available. For this reason it’s important to check the ISO diameter too for clarification, especially for 26” wheels.
Bike Type - the type of bike the tyre was designed to be used on. Road tyres will generally be narrow with minimal tread, touring tyres wider with a bit more grip in the tread, and cyclocross & MTB tyres wider still (especially the latter), with a much more pronounced tread pattern.
ISO Diameter - this relates to the diameter of the wheel rim at the point where the tyre is seated (bead seat diameter). This is a universal measurement, often displayed on tyres as 28-622 or similar, 28 referring to the tyre width and 622 being the ISO diameter in millimetres.
TPI - stands for threads per inch and refers to the thread count of the tyre casing. A high thread count usually means a more supple and lighter tyre, this can be anything as high as 320 tpi. We can’t always provide this information however, as it’s not always possible to know for sure.

NB: Most tubular tyres use lightweight latex tubes that lose air over the course of a few days so will need re-inflating regularly. If mounted in the photos this is for illustrative purpose only, any wheels or rims shown are not included.OVERVIEW
TECHNICAL INFO
Tubular Wheel Size - standard/full size tubulars only come in one wheel size, these are often referred to as 28" or 700c (sometimes even 27"). These are all the same size, the next size down is 26", so any wheel larger than 26" will take a standard/full size tubular.
Width - the width of the tyre as stated by the manufacturer (if present), if there are no markings we measure at the widest point when fully inflated. Depending on the manufacturer, the stated width can differ slightly from the actual width when measured, although usually this only minimal.
Bike Type - the type of bike the tyre was designed to be used on. Road tyres will generally be narrow with minimal tread whereas cyclocross tyres will be wider with a more pronounced tread pattern, and MTB tyres even more so.
Casing - the main structure of the tyre that surrounds the inner tube and provides the base for the rubber tread. Most tubulars have cotton casings but other materials are used such as nylon, kevlar or silk. We can’t always provide this information as it’s not always possible to know for sure.
TPI - stands for threads per inch and refers to the thread count of the casing, if known. A high thread count usually means a more supple and lighter tyre, this can be anything as high as 320 tpi.
Valve Core - some valve cores are removable allowing you to add sealant or valve extenders, if the valve cores are fixed this is not possible.

A fine choice for keeping your classic bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Chainset Type - the number of chainrings the derailleur was designed to work with. ‘Double’ derailleurs are actually capable of working on ‘triple’ chainsets but they may struggle when shifting, especially if there’s a big step down from the middle to inner ring, so it’s better to match these correctly.
Frame Fixing - the way the derailleur fixes to the frame, if you have a tab on your frame to mount the derailleur to you need braze-on. If there’s no tab then you require a clamp-on type (also referred to as band-on or clip-on), these come in different sizes to match the diameter of your seat tube.
Pull Type - the direction of which the cable needs to ‘pull’ the mech in order to shift. If your cable runs up to the derailleur from the bottom bracket area then you need bottom pull, if your cable comes down from above you need top pull. Some later derailleurs can be used for either setups, these are referred to as dual pull.
Designated Speed (9 Speed & Above) - the speed of the chain that the mech was designed to be used with. This only becomes relevant for mechs marketed as 9 speed or above when chains became narrower, as the derailleur cage plates became marginally narrower too. We refer to it as ‘designated’ speed as technically you can use (almost) any derailleur with any chain, however if you want optimum performance it’s best to stay close to the manufacturers recommendations.
Indexing System (Shimano Only) - this is only applicable when using Shimano shifters that have an indexed left shifter such as STI or Rapidfire. For the indexing to work correctly when using these shifters the derailleur and shifters must be of the same type, so Shimano drop bar shifters need to be matched with a Shimano ‘road’ derailleur, and Shimano flat bar shifters must be used with Shimano ‘MTB’ derailleurs.

OVERVIEW
TECHNICAL INFO
Fixing Type - if you have small mounts on either side of the frame’s down tube you need braze-on shifters, if there are no mounts you’ll need clamp-on (sometimes referred to as band-on). Some 'aero' frames have mounts fixed to the top of the down tube, for these frames you require top mount shifters for the correct boss type (see below).
Shift Type - friction shifters don't click into gear when you change, when they do click it's referred to as indexed shifting. For this to work correctly you must use the same system as your rear derailleur, if you're using friction levers you can mix and match. You don't need to worry about the front derailleur as left downtube shifters aren't indexed.
Speed - the number of cogs at the back the right shifter is designed to be used with. This is important with indexed shifting but with friction shifters you can in theory run any shifters with any speed setup, although the right lever will need to be pulled back further to shift into the larger cogs.
Shifter Boss Type - the shape of the mount (for braze-on fixings only). Campagnolo / ISO is standard and easily identified by the flat sections on either side, usually combined with a square base for the backing stop plates to fit. There are also Shimano ones with a keyhole shaped base and much less common French ones that are round with no flat sections.
Boss Thread Size - M5 (5 mm) is standard for Campagnolo / ISO bosses, but Shimano bosses will often have M4.5 (4.5 mm) threads and the French bosses would likely have 5 x 1 mm threads.

Atax stem, hailing from France and dating back to 1994 (yet still new & unused after all this time!). Made from aluminium/steel and weighing in at 318 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Extension Length (ctc) - this is measured from the centre of the handlebar clamp to the centre of the shaft, to the point where the stem bolt passes through. We always take this measurement in a straight line through middle of the extension, not along the top.
Quill Size - the most common size for classic and vintage road bikes is 1", this should be the same as the outside diameter of your fork's steerer column. Oversized steerers found on mountain bikes and later road bikes will be either 1 1/8" or 1 1/4".
Steerer Size (ID) - this is the most important measurement when checking the stem fits your bike. This should match the measurement of the inside of your fork's steerer column, where the stem will be inserted. The standard size for road quill stems was 22.2 mm, or 22.0 mm in France until the 1980s.
Total Shaft Height - measured from the top where the expander bolt head sits, to the bottom of the stem's shaft. To give you an idea of how high the stem can be set, there should be an absolute minimum of 50 mm inserted into the fork steerer, although most stems come with a 'minimum insertion line' to help with this.
Clamp Size - this should match the outside diameter of your handlebars and should be as close as possible to ensure a good and safe fit.

OVERVIEW
TECHNICAL INFO
Chainring count - the number of chainrings on the chainset. Fixed gear track bikes, single-speeds and some geared bikes use a single chainring, road bikes commonly use a double (two rings) and most touring bikes and mountain bikes will use a triple chainset (three rings).
Tooth count - the number of teeth on the chainring(s), the higher the number the harder the gear.
Chain width - this is only relevant for chainsets with a single chainring - if this is ⅛” then you must use a ⅛” chain. All double and triple (and some single) ring chainsets will use a standard 3/32” chain.
BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter) and is only really needed when changing chainrings. To calculate the BCD, measure the distance in millimeters from the centre of any chainring bolt to the centre of an adjacent one and multiply it by 1.709 (you’ll likely need to round the resulting number up or down a little to get your BCD measurement).
*Intended speed - the number of cogs at the back the chainset was designed to be used with. We refer to it as ‘intended’ speed as most double and triple chainsets will actually work with different speeds than originally intended, but the further away you get from the intended speed the more likely you are to experience minor setup issues. The exception being some chainsets intended for 10 speed use or higher, with these it’s better to stick to the intended speed.
Crank length - this is measured from the absolute centre of the bottom bracket hole to the centre of the hole for the pedal.
Pedal threads - the pattern of the thread that your pedals screw into, this is usually stamped on the pedals themselves and most bikes use a standard thread of 9/16” x 20 tpi. The exceptions being older French bikes, bikes with cheaper one-piece type chainsets and Shimano’s Dyna Drive system (easily identifiable as the pedal holes are about an inch wide!).
Bottom bracket type - ‘square taper’, as the name suggests have a square shaped axle that slots into the chainset and ‘cottered’ axles are round and secured by pins - pretty much every bike up until the 1990s would use one of these, cottered being the much earlier system. Since then, different manufacturers have introduced their own systems that are not interchangeable so you must use a chainset that matches.
