CH MR-2437-LLB Ceramic Hybrid Enduro Bike Bearing 24x37x7

Best value ceramic bearings I could find for my bottom bracket. Non-contact so less friction.

Fast delivery and great customer service as always.

Upgraded the bearings on my Specialized Tarmac to these and the difference is hugely noticable! Sure I've gained at least 5 watts. Great price plus £15 fitting at my LBS - job done.

Quality piece of kit,upgrade from normal enduro bearing.

I’ve got 6 bikes and they constantly need bearings, but finding replacements was a bit of a nightmare. However, I’ve used Wych bearings now for a few years, they have a clear understandable website and give you a choice of bearing types and delivery is super fast. I won’t use anywhere else now

It's early days yet but had the bearings in for a month now and I've used my bike every weekend in this hot summer. The previous bearings would wear out within a year and this bike is my summer bike only so doesn't get used much. The bearings have been on 2 x 100 mile bike rides and they are silent compared to standard bearings they do feel really smooth to which is nice. Longitivity well have to see by the end of the year to see if they are still running the same but so far I'm really impressed. These bearings costing 3 times as much as the standard bearings can only be due to the bearings performance and the longitivity. I'm glad with the purchase though as the bike shop quoted me double this amount and said there special bearings that go in my bike frame.

Arrived super quick. Happy customer

Superb advice given and fast efficient service from Wych - and these are a a great. Slur product that roll super smooth. Too early to give feedback on their longevity but seem very good so far

Just the bearing needed for my Trek Domane. Easy to find, easy to order, very swift delivery even though it was standard UK
