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).

Cap Type - we refer to the classic cycling cap type as summer/under helmet, although they can of course be used all year round. When worn under a helmet they provide comfort, sun protection and are sweat-wicking too. Winter hats will usually cover the ears and are referred to as 'Belgian' caps. Baseball caps were often worn by support teams or sold as branded merchandise.

Construction - the number of panels the cap body is made up of, not including the peak.

Pit to Pit - this measurement is taken from the centre of one armpit to the other, across the chest with the jersey laid flat.

Top to Bottom - this will always be from the very top of the collar to the very bottom hem, we provide measurements for both the front and back, always taken with the jersey laid flat.

Shoulder Seam to Sleeve End - this measurement is taken from the shoulder seam down to the very end of the sleeve on the outside.

Across Neck - for consistency on all neck shapes we gather the front and back together and lay them flat, then measure across the stitching (as shown in the supporting photos).

Across Sleeve End - measured across the sleeve end, laid flat.

Position - some brake pads are designed for front or rear use only, although most can be used on either. If they are front or rear specific they should only be used in that position.

Brake Fit - brake pads are specific to the type of brake so you need to use the correct ones.

Compatibility - the brake pad holders (also known as shoes) the inserts are designed to fit.

Rim Type - some wheel rims such as ceramic or carbon require brake pads to be made of specific compounds. If you have steel rims you can use pads designed for alloy rims but you will get much better performance when using the correct pads.

Optimal Speed - the ideal number of rear cogs, based on the outer width of the chain and the cog width it was designed for. For 6 Speed Shimano Uniglide a 5/6 spd chain will perform best.

Shifting System(s) - indexed shifters 'click' when you change gear. For 9 speed upwards (or Suntour Accushift), to guarantee the best performance we recommend using the dedicated chain. Otherwise, for 8 speed and below, or any speed when using friction shifting (non-index), you just need the correct outer width.

Outer width - measured across the rivets at the widest point, these are the approximate widths for different speed setups (up to 4 speed is also dependent on cog width):

Cog Width - the gap between the inner plates allows for different rear cog/sprocket widths. 3/32" is the standard for 5 to 8 speed, above that it’s 11/128”. For 4 speed or less, 3/32” and 1/8” were both used, for the latter you will need a 1/8” chain. A wider 3/16" moped chain can be used as a heavy duty opton for single cog setups if required).

Chain pitch - the distance between the rivets/pins. All chains will be 1/2" with two exceptions; 3/16" (“inch pitch”) for very early track bikes, or Shimano's short lived 10 mm pitch system from the 70s/80s.

Number of links - if you're unsure how many you need, measure your old chain (each link has two rivets) or one with a similar setup to yours.

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.

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.

Bearing Size - most bottom brackets use 1/4" bearings, but there are some that use smaller sizes so it's advisable to measure your old ones or check with a local bike shop to be sure.

Retainer Type - you can use any type of retaining cage in any bottom bracket as long as the bearing sizes are correct.

Position - rear cables need to be longer than fronts, this is the only difference so cables long enough for the rear can also be used on the front.

Cable Type - brake and gear cables have different specifications and are not interchangeable.

Casing Width - the outside diameter of the housing. Brake cable housing is a little wider in diameter than gear, this is to accommodate the slightly thicker inner cables.

Length - it's important to check the cables are long enough for your setup. Some gear cables are designed for downtube gear levers only and there won't be enough cable to be used otherwise.

Brake End Nipple Type - Pear' type cable ends step down in size to allow them to be used with drop bar brake levers normally found on road bikes, whereas flat bar levers usually require a 'barrel' end that sits in a similar shape slot within the brake levers.

End Nipple Diameter - for 'pear' type ends this is the diameter at its widest part, with barrel ends it's the diameter of the circular part.

Speed - the number of cogs on the freewheel.

Range - the number of teeth on the smalles and largest cogs, this gives you an indication of how hard or easy the gearing will be, the lower the number the harder the gears. The tooth count of the cogs inbetween are usually evenly spaced, ie: a 6 speed 14-24 freewheel would likely have cog sizes 14, 16, 18, 20, 22 & 24.

Threading - this needs to match the thread of your rear hub. ISO is the modern standard and is almost exactly the same as older English/British and Italian thread, allowing you to mix and match between these thread types as long as it's not going to be under extreme force, in which case it's best to stick to an exact match. Hubs with a French thread must be used with a French threaded freewheel.

Stack Height - the total height (or width if you're looking at it when installed) of the freewheel, this is measured from the base (back of the largest cog) to the top (front of the smallest cog).

Chain width - this is mainly relevant for singlespeed and some older 3 or 4 speed freewheels - if this is ⅛” then you must use a ⅛” chain, but most freewheels (especially multiple speed ones) will use a standard 3/32” chain.

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.

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 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.

Chainring Count - the number of chainrings the crank was designed to fit. 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).

BCD - stands for Bolt Circle Diameter (sometimes referred to as PCD - Pitch Circle Diameter), and this needs to match the BCD of your chainring(s). To calculate this, measure the distance in millimeters from the centre of any chainring bolt hole 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).

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 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 crank 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 crank that matches.

Chainring Count - the number of chainrings the crank was designed to fit. 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).

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). There are also 'Clamp-Over' shifters that allow front & rear shifters to be used on a frame that only has a single braze-on.

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.

Brake Fit - brake pads are specific to the type of brake so you need to use the correct ones.

Pad Type - replaceable (also known as cartridge) brake pads have inserts that can be replaced once they wear out. With one piece pads you do not have this option.

Rim Type - some wheel rims such as ceramic or carbon ones require brake pads to be made of specific compounds. If you have steel rims you can use pads designed for alloy rims but you will get much better performance when using the correct pads.

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.
