Sturmey Archer CS-FR3 Cassette Hub (rim brake)

In stock

£97.99 incl tax

This is a 3 speed internally geared hub that has an integrated cassette mounting so that you can slide on a 8 or 9 speed cassette. At first thought this might sound wierd...

...however it means you can do away with the annoying front derailleur mechanism and triple chainset on your bicycle. This gives the bike a much cleaner and simple set up and look which is good for reducing the amount of maintenence required on a bike that's used every day. It still means that you get the similar spread of gears as on a triple chainset bike but without the annoyance of a front mech.

It comes with all the fitting parts to fit it to your bike (once you have had it built into a wheel that is!), It does not include the 3 speed shifter becasue it is designed to work with standard left hand mounted mountain bike (flat bar) shifters (won't work with road shifters).

Internal gear ration is 177%
