Valve Type - there are 3 types of valves; Presta are thin with a little knurled nut on the end, Schrader are wider (the same as you would find on a car), and the less common Woods (aka "Dunlop"). Pumps designed for Presta valves can be used on Woods valves. Some pumps use hose connectors, these are available for all valve types.

Pump Mount Type - 'peg fit' pumps require pump pegs or 'umbrella' clips to fit to the frame, 'frame fit 'pumps are designed with curved ends to mount between two tubes (although these often have holes for pegs too). If mounting directly you'll need the correct length to fit your frame, or a clip/peg to hold one end.

Mount Location - frame fit pumps usually mount to the seat tube with the ends compressed between the top and down tube, they can however be mounted on other tubes as long as there's something supporting the handle end. Some head tubes have a little nipple or a small enough gap for under top tube mounting (this can be replcated with a simple strap or cable tie), and of course pump pegs or clips can be fitted anywhere!

Length (Min-Max) - the length of the pump fully compressed and uncompressed, measured at the points of support. The space you to intend to mount the pump should be within 1 cm of the minimum or maximum length to allow the pump to be securely mounted and dismounted.

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).

Cog 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.

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.

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.

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.

Crank Thread - 22 mm is the standard thread for almost all cotterless crank arms, 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.

Clamp Opening - the minimum and maximum distance between the inside of the nut and bolt heads. The minimum is measured with the bolt tightened as much as possible (for hex head types this may mean the bolt end will stick quite far out of the nut). For the maximum opening we ensure 5-6 mm of thread remainis in the nut for a secure fixing.

Outer Diameter - the part that goes through the frame, most steel frames will take an 8 mm bolt whereas early lugged aluminium frames often have a larger hole that takes a 10 mm bolt diameter.

Bolt Fixing Type - some binder bolts have tightening mechanisms on both sides to secure the seatpost in the frame. Single sided bolts need something else to help; some have knurled parts that grip the inside of the bolt hole, others have a small notched 'key' locator that lines up with a cut-out in the frame (if you have one).
