MH-P21 1-3/8" Headset Bearing 37x49x7 45/45
Typical Applications: Headset Bearing, Specialized Roubaix road bikes
I wanted a pair of headset bearings for my Specialized cyclocross bike and, after some online research, came across the Wych Bearings website and found what looked like the correct size of bearing and it stated that they were suitable for Giant and Specialized bikes which other websites didn't. Just to make sure I phoned them and the person I spoke to was extremely helpful and assured me that if they did turn out to be the wrong ones I could return them for replacement or refund. When they arrived they were perfect and took me about ten minutes to install. The top bearing was MH-P08F 1-1/8" Headset Bearing 30.5x41.8x8 45/45 which was, also, perfect. Definitely use Wych Bearing again.
