FSA SX PRO (I/I)

FSA SX PRO (I/I)

NO.55

With semi-integrated cups top and bottom, the SX Pro fits seamlessly into tapered headtubes with a 50mm outside diameter at the top and a 61mm diameter at the bottom. It’s designed for a 1 1/8-1.5in tapered steerer tube. Sealed cartridge angular contact bearings are used top and bottom for long-lasting, smooth-running performance with minimum maintenance. Construction is all aluminium, with a forged upper cup and CNC machined lower, contributing to an impressively low weight.
