Radial Bottom Bracket Bearing featuring 52100 High-Carbon Chromium alloy races paired with grade 5 Balls with 90% fill, high-pressure, water-proof grease. Designed specifically bicycle applications, the LLU/LLB seal combination on these bearings utilizes a more protective LLU seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) LLB seal face inward to keep the grease where it belongs.
The most common use for this bearing is as a direct replacement bearing for Shimano external cup BBs when using the plastic Shimano bearing insert. If you wish to avoid using the plastic insert MR 2437 is the correct bearing for the job.

I recently took my dated and tired old racing bike along to Leeli Cycles for some much needed work. I was cheerfully greeted by Ben the very friendly owner and number one mechanic. He suggested a full service and looked over the bike to access the condition of the other cycle components. A very comprehensive quote was later emailed to me listing all the parts that Ben would require to complete the job. He phoned me as soon as my bike was ready and I hurried along to pick it up. My first reaction was, wow! It looked as good as new and fully roadworthy again. Ben had done an incredible job in transforming my old racer back to its former glory! I'm very pleased to have used Leeli Cycles along with Ben's wealth of mechanical knowledge, sound advice and attention to detail. Even happier still to support this amazing small local business offering great value and excellent customer service. An outstanding shop in every way for all your cycling needs with the personal touch. Pop in and see for yourself. I guarantee you won't be dissapointed.
