Specialites T.A. Cyclotourist set of chainring bolts (or screws if you prefer), hailing from France and in production from the 1970s to the 1980s (yet still new & unused after all this time!). Made from steel and weighing in at 42 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
If you're taking part in L'Eroica, Anjou Velo, Velo Retro or another similar vintage cycling event, these are fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong chainring bolts!
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).

Cage Fixing - most bottle cages will be designed to fix to the frame, although some rare older ones mount to the handlebars and/or stem. If your frame doesn't have any bottle cage braze-ons to fix to you'll need a clamp-on bottle cage.
Bottle Fit - almost all cycling bottles measure between 70 - 75 mm in diameter so this is the standard bottle cage size, the only rather rare exceptions are some old Elite bottles that require a 66 mm cage, the more recent oversized ones and of course the funny shaped aero ones that only accept the bottle they were made for.

OVERVIEW
DETAIL & MEASUREMENTS
Cleat Type - slotted' cleats fit onto traditional pedal cages and the foot is secured with toe clips and straps, various fixings types exist and some are brand specific. Most cleats for clipless road pedals fit the 3 bolt fixing invented by Look in the 80s, the exceptions being the 4 bolt fixing for Time's TBT system (and later Speedplay), and the Podio specific fixings for Merckx shoes. Mountain bike (SPD type) cleats have a standard 2 bolt fixing, and some shoes are even designed to take more than one type of cleat!
Length (Heel to Toe) - measured from the very back of the heel to the front of the toes at their furthest points. We find this measurement useful if you have a similar shape shoe to compare to, and although there will be variation in design, when combined with the width it can be helpful in determining whether the shoes will be a close fit or not.
Width (At Widest Part) - measured across the metatarsal at the widest part of the shoe, on the outside, not the inside.
If you require any further measurements please get in touch.

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 axle!
OVERVIEW
TECHNICAL INFO
Axle Type - for square tapers, the ISO introduced a standard for European makers in the early 90s, JIS then did the same in Asia. Before then it was not so simple, and although there is a degree of interchangeability, the best way to make sure you have the right axle is to stick to the same brand from the same era, ideally the proprietary model.
Axle Length (D) - your crankset dictates the axle length you need and the recommendation should be used to avoid issues with chainline. If you're replacing an axle that works perfectly then this can be matched, otherwise you'll need to check the manufacturers spec, a good resource for older bikes is Velobase.
Centre (B) - measured from the outside of the 'shoulders' of the bearing races, as seen in the diagram.
Drive Side (C) - the right side (with any logos etc on the axle facing you), your right crank and chainrings will mount to this side.
Non-Drive Side (A) - the left side, where the left crank arm will be mounted.
Shell Width - the width of the bottom bracket shell the axle was designed to fit, measured at its widest point.

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 wheels. 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 tyres were 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 rims at the point where the tyres are 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 casings. A high thread count usually means more supple and lighter tyres, 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.

Please note: Once inserted into a frame this cannot be returned, so please make sure to double check the diameter is correct before installing.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 (Centre of Rails to Base) - measured from where the centre of the saddle rails will sit once installed, all the way 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.
£22.50 £30.00

Strong seatpost, hailing from Japan and in production during the 1980s (yet still new & unused after all this time!). Made from aluminium/steel and weighing in at 217 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 a similar vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong seatpost!
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.

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).
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
Thread Type - this must match the bottom bracket thread on your frame. The 3 common thread types on classic and vintage bikes are English (also known as British or ISO), Italian & French, and are usually (not always!) found on frames built in their respective countries. If you're replacing a bottom bracket the cups should have the thread type stamped on one of them, if not there are a couple of things to look at; bottom bracket shell width (English & French = 68 mm, Italian = 70 mm) & drive side cup thread direction (English = left, Italian & French = right). The only curveball to watch out for here, although pretty uncommon, are Swiss threads (also found on some French frames, Motobecanes being one) which will have the same shell width & thread direction as an English thread frame but the actual thread pitch will be different. If none of the above matches what you have, there are a few lesser known varieties that will require some further research.
Axle Length - your crankset dictates the axle length you need and the recommendation should be used to avoid issues with chainline. If you're replacing a bottom bracket that works perfectly then this can be matched, otherwise you'll need to check the manufacturers spec, a good resource for older bikes is Velobase.
Axle Type - you can tell which type of axle you need just by looking at the shape of the bottom bracket hole in your crankset. The square taper axle came in two variations; JIS which was produced for cranksets made in Asia and ISO for cranksets made in Europe, these taper down to a slightly smaller end than JIS axles. There are a few exceptions such as some Sugino cranksets that required an ISO axle and some older Dura-Ace cranksests which used a shorter 'low profile' variation of the JIS taper. Ofmega/Avocet also had their own variaton of the ISO taper which is not compatible with any other type.

Made from aluminium and weighing in at 282 grams - pretty lightweight for a stem at that time. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike too.
OVERVIEW
TECHNICAL INFO
Extension Length (ctc)* - we measure from the centre of the handlebar clamp to the centre of the shaft, to the point where the stem bolt passes through, to the nearest 5 mm. We always take this measurement in a straight line through middle of the extension, not along the top. In some cases the stem may be stamped with a different extension length as some manufacturers measured differently, but we always use our own measurement for consitency.
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
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.
£19.13 £22.50

OVERVIEW
TECHNICAL INFO
Bottom Bracket Thread Type - this must match the thread of your bottom bracket for the lockring to fit.
Thread Direction - most bottom brackets only have an adjustable cup on the non-driveside of the bike, so lockrings mostly thread to the right (clockwise), regardless of the thread type. However, some bottom brackets have adjustable cups on both sides so the thread direction may be different.
Thickness - this is rounded to the nearest 0.5 mm.

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 arm 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 thread type to match that of the chainset, this must match and 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.

OVERVIEW
TECHNICAL INFO
Skewer type - quick release skewers allow you to remove the wheel without any tools, whereas allen key and security skewers require a tool to allow the wheel to be removed.
*Spacing - this should be within a few milimetres of your frame & fork's outer dropout spacing (measured from the outside where the skewers clamp down). The measurement provided was taken with the exiting hole of the end nut flush with the end of the skewer. There will be some wiggle room to allow a narrower or wider dropout spacing to fit, we've provided the threaded section and end nut measurements to give you an indication of how much.
Threaded section - the amount of thread on the skewers for the end nut to be threaded onto.
End nut length - the total length of the nut from end to end.
