We are experts in bicycle headset bearings. With different headset and bicycle manufactures using their own codes and names for bearings, it can be a minefield trying to work out the correct bearings. We sell individual bearings and kits for bikes and headsets. Our bearings are sourced from the best suppliers, and all our bearings are tested. We are cyclists ourselves!

A full bearing kit for either:

NO.57SC

NO.57SC1



You will receive 1 x upper and 1 x lower bearing for an FSA headset. These bearings have been carefully selected from a quality supplier. Precision milled and Mobil grease used. These are better than other generic bearings you may find, carefully selected, but remain at a competitive price. 


No need to look any further for individual bearings and numbers. Buy this kit, fit to headset and get riding. Easy! We offer free returns if the bearings do not fit.


RRP for FSA bearings are £35, the same prices as a whole new headset! These are just as good and a lot cheaper!


What you will get: 


1 x 1 1/8" Upper Bearing MR083
 34x46.8x7 45/45



1 x 1.5" Lower Bearing MR152 =

40x51x6.5 36/36



Take out old bearings, clean the cups, grease cups with grease, fit these new bearings and some more grease.
