Customer came in to see me today with a deep groove ball bearing off a bike. I measured it and googled it and it turns out to me an Enduro bearing. Now at one time these bearings were exclusive to the cycle shops and we independent traders didnt have any supply sources. Times have changed and now WMT Bearings can in many cases offer you Enduro cycle bearings wherever you are in the country generally on quick lead times. We are based in Shrewsbury, Shropshire. Give us a call and let us know what you require, we will source and quote.
