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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
