Silly Bike Boy Bearings
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!
For sale is a full bearing kit to hit these FSA headsets:
- FSA No.42/ACB
- FSA Orbit C40-ACB
- FSA Orbit CF-40-ACB
- FSA ACB-CX
These will not fit Headsets called FSA No.42 or FSA Orbit C-40, as these require a different lower headset bearing.
These are integrated headsets for tapered forks i.e 1 1/8 upper and 1.5 lower. Please see photos to check
You will receive 1 x upper and 1 x lower bearing for an FSA headset. The diagrams and photo of headset are for illustration only,
The bearings are not official FSA. These bearings have been carefully selected from quality supplier, Minhon. Precision milled and Mobil grease used. Black Oxide anti rust protection used on our bearings. Ideal for UK winters! These are better than other generic bearings you may find, carefully selected, but remain at a competitive price. However, they are not FSA own brand. WATCH OUT FOR COPYCAT SELLERS, we offer the best bearings on ebay.
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.
Satisfaction guaranteed. We are experts in bicycle headset bearings. Do get in touch with any questions on compatibility and we will be able to advise.
