Across Waist Band - this measurement is taken across the waist band at the top of the leggings whilst laid flat, without stretching the elastic. To work out the waist circumference this measurement needs to be doubled.

Across Hips - some waist bands are quite high so we also measure around the hip area. This is taken across the leggings whilst laid flat without stretching the elastic, where we assume the hips to be. This is an approximate measurement provided as a guide only.

Full Length (Outside Leg) - measured from the top of the wasit band to the bottom of the hem, measured along the outside of the leg.

Inside Leg - measured from the centre of the crotch to the bottom of the hem, along the inside of the leg.

Across Quads - some leggings can have particularly tight or loose legs, so we also measure around the quad area to help with this. This is taken across the leggings whilst laid flat without stretching the elastic, where we assume the quads to be. This is an approximate measurement provided as a guide only.

Across Bottom Hem - taken across the bottom of one hem whilst laid flat, without stretching the elastic. To work out the hem circumference this measurement needs to be doubled.

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.

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).

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.

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!).

Speed - the number of cogs at the back the chain was designed to be used with.

Compatibility - the brand and/or shifting system the chain is compatible with. Universal means the chain can be used with any standard shifting system, as long as the speed and width are correct.

Chain width - the gap between the inner plates where the chain sits on the sprockets. 3/32" has been standard for bikes with derailleur gears since the mid 1900s. When 9 speed was introduced the spacing reduced slightly but if the speed & compatibility are correct this isn't something you need to pay attention to. Single speed, track & BMX bikes will require either a 3/32" or 1/8" chain depending on the width of the rear sprocket and/or chainring. There's also a much wider 3/16" moped chain which can be used as a heavy duty chain for bikes without gears if required.

Chain pitch - the distance between the rollers (the cylindrical parts that roll around the pins). Pretty much every bicycle chain will be 1/2", the only time you will need a different pitch is for very early track bikes that take a 3/16" chain (also known as 'inch pitch'), or Shimano's short lived 10 mm pitch system from the 1970s/80s.

Number of links - the total number of links in the chain. If you're unsure how many links you need, you can measure your old chain (or a bike with a similar setup to yours).

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.

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).
