They are perfect for renewing the steering of the Specialized Turbo Levo, in my case the 3rd generation.

I had to dismantle the old one and assemble this one.

Luis

It is the correct one for Specialized Epic Expert 2018. I just had to disassemble the old one and assemble the new one, it still has the spacers and top cover that didn't need to be replaced, but I changed them to make everything new.

Compatibility with 2021 SJ COMP ALLOY

2025/04/10

Sean

Hi, just want to double check that this is compatible with a Specialised Stumpjumper 2021 Comp Alloy bike. The specs for the headset on that bike or as follows, according to the retailer web page.: 1-1/8" Campagnolo standard compatible upper bearing, 1.5" lower bearing

Answer of philippe

Hello, if you have any doubts, the best thing would be to disassemble the fork and measure the bearings with a caliper, no special tools are required. In my case, enduro spec, the most worn/seized bearing was the lower one: 52 x 39.9 x7, that of this kit: 1.5´´ Lower bearing: 52mm OD x 40mm ID x 7mm Thickness (45x45 degree) was perfect as was the rest supplied.
