ACB 4545 125L SS Headset Bearing 34.1x46.8x7 45x45°

Excellent service! Took 3 attempts to get the right size but can just return the others for a rfund

I needed a replacement lower headset bearing for my Colnago roadbike. Having looked at the usual bike sites, I found Wych Bearings. It was easy to find the bearing I needed, and it was significantly cheaper than the bike shops. The bearing arrived in just a few days, well in time for my cycling trip to Gran Canaria. The quality of the bearing is great - far superior to the one it replaced. Will definately use Wych Bearings in future.

It moves freely and it fits. What’s not to like.

as always a great quality headset bearing from Enduro, perfect replacement for lower quality OEM headset bearings. Delivered very quickly by Wych bearings

Wych Bearing is our go-to bearing supplier for all cycle related bearings for wheels, headsets, bottom brackets etc. This product was a perfect replacement for one we needed and was delivered really quickly.

Excellent service, quick despatch and bearings good quality

This is the correct replacement for the headset bottom bearing on my 2015 size 61cm Specialized Roubaix, notwithstanding that even Specialized themselves thought it should be 1.375 inches. Your Roubaix may vary, so measure the old one first.
Anyway, it's stainless, it's shiny, and it has that almost unreal feeling of a top quality bearing: devoid of friction and stiction in rotation, and in every other direction totally solid. It's so obviously a top notch part that it feels like a shame to seal it out of sight inside the frame.
Service, delivery and quality are first class.

Good end to end service with seamless delivery.
