Pre-1987 (Eroica Compliant)

We've been safely sending orders around the world since 2010. There's a handy shipping calculator on the shopping cart page so you can see the cost of postage as soon as you've added it to your basket. Your order will be carefully packed and sent with tracking & insurance, we despatch most orders within 2-3 days but larger items and orders placed before the weekend can take an extra day or two to process.

We accept returns, please notify us within 14 days and ensure the item arrives back with us no later than 30 days after the order was received.

We don't charge VAT, however, if buying from outside of the UK please remember that there may be import fees to pay directly to the delivery company before receiving the order. Unfortunately we can’t advise on the exact costs as it varies from country to country, so please check your national rates before purchasing.

Cable Routing - non-aero means the cables come out at the top of the brake levers, meaning the cables are on show. With aero levers the cable comes out of a small hole by the handlebar, allowing the cables to be hidden under the handlebar tape.

Bar Clamp Size - this should be close to the outside diameter of your handlebars at the point the brake levers will be fitted. This will rarely present a problem with drop bars as 23.8 mm is standard, and a 24.2 mm clamp will fit just fine as they do have a little adjustment in them. There are some older sizes to watch out for but these will be noticeably different.

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.

Caliper Type - side pull calipers (single or dual pivot) require nothing more than a brake hole to fix them to as the cable feeds straight into one of the arms, whereas centre pull calipers require a brazed-on or fitted cable hanger to allow the cable to be pulled from the centre.

Brake Drop - measured from the centre of the brake mounting hole to the centre of the wheel rim, measured in a straight line. Your measurment must be within the range of the caliper's given brake drop.

Brake Fixing - this refers to the way the brake is secured to the bike. For recessed allen key fixings the hole to the rear of the the fork crown/brake bridge should measure around 8mm, allowing the allen key head to be inserted and fixed to the brake bolt. External hex nut fixings require a hole of around 6mm, the hex nut is fixed to the protruding part of the brake bolt.

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.

Drilling - the number of holes for the spokes.

Rim Size - the sizing given by the manufacturer, these can be confusing so we also give the ISO diameter too for clarification.

ISO Diameter - the diameter of the 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.

Valve Type - presta valves are the thin ones and Schrader are the fatter ones. Schrader valve holes will also accept the older Dunlop/Woods type valves.

Rim Width (OD) - the width of the rim, measured from the outside of one wall to the other.

Rim Height - the overall height of the rim, measured to the highest point of the rim’s profile.

Capacity - 500ml used to be the standard sized bottle, but the taller modern versions tend to be 750ml.

Bottle width - almost all bottle cages take a 75 mm bottle width, the only rather rare exceptions are some old Elite cages that take a 66 mm bottle (and of course the funny shaped aero ones).

Plug Type - expanding plug inserts can be adjusted within the given range to fit different handlebar inner diameters. 'Push-in' plugs cannot do this, however they are usually designed to flex a little to give you some wiggle room.

Plug Insert Diameter - this needs to be a close match to the inside diameter of your handlebars, although the plug diameters can be increased a little using tape (cloth handlebar tape is perfect for this). The ranges given for expanding plugs are rounded to the nearest 0.5 mm.

End Stop Diameter - the width of the end cap that butts up to the ends of your handlebars.

Headset Type - the 1" size relates to the outside diameter of your fork's steerer column which should measure 25.4 mm, if it's 25.0 mm your forks should be French threaded. Although it's generally recommended to match threaded parts exactly, with headsets you can technically mix and match, unless you have French or the obscure old Raleigh threads, in which case you need to stick to that type. If you're replacing an old headset the thread may be stamped on there. Oversized 1 1/8" & 1 1/4" sizes are easily identifiable due to their size and the threads are all standard.

Cup Size (OD) - the outside diameter of the cups, this must match the inside diameter of your frame's headtube closely for a good fit. For 1" headsets this should be around 30.2 mm unless you require a JIS headset which will be 30.0 mm.

Crown Race (ID) - the inside diameter of the crown race where it sits on the fork steerer, this needs to be close to the outside diameter of your fork steerer at the base to ensure a proper fit.

Stack Height - the overall height of the headset. To check the minimum stack height you require, measure the length of your frame’s head tube & subtract this from the length of the fork steerer column. You can always add spacers if you have a little too much steerer tube but you can't fit a headset with a greater stack height than the space you have available.

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.

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 Size - almost all cycling bottles measure just under 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.

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'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.

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.

Crank Thread - 22 mm is the standard thread for almost all cotterless cranks, the only exceptions are some Stronglight cranks made up until the early 1980s, and Specialites T.A. Campagnolo produced some self-extracting crank bolts with covers that had a reverse thread.

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.

Shifting system - friction means your gear levers don't click when you change gear, when they do click it's referred to as indexed shifting. If you have indexed gear levers they must use the same system as the rear derailleur, if you're using friction levers you can mix and match.

Speed - the number of cogs at the back the derailleur was designed to be used with. This is important with indexed shifting, but with friction shifters you can in theory run any rear mech with any number of cogs, but you are more likely to have issues running high numbers of cogs with mechs from earlier eras.

Max cog size - the amount of teeth on the largest cog of your freewheel/cassette can be no greater than this to work with this derailleur.

Chain wrap - subtract the size of your smallest rear cog from your biggest, then do the same with your chainrings, add the 2 numbers together and you have your chain wrap.

Chain width - generally speaking, derailleurs designed for more than 3 speed use will fit a standard 3/32'' chain, the exception being some Cyclo & Simplex models from around the mid 1900s.

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.

Your order will be carefully packed and sent with tracking & insurance, we despatch most orders within 2-3 days but larger items and orders placed before the weekend can take an extra day or two to process.

We accept returns, please notify us within 14 days and ensure the item arrives back with us no later than 30 days after the order was received.

We don't charge VAT, however, if buying from outside of the UK please remember that there may be import fees to pay directly to the delivery company before receiving the order. Unfortunately we can’t advise on the exact costs as it varies from country to country, so please check your national rates before purchasing.

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.
