T47/86 30mm Bottom Bracket Gravel
T47 is a standard created by custom frame builders. It’s threaded, has an inner diameter of 47mm, and is 86mm wide. It has the design benefits of being oversized and wide, but also the practical benefits of threads.

Technical Data
With the benefits of both oversized shells and the tight fit of threading, T47 has the best of both worlds. These cups and bearings make it possible to run stiff and light 30mm spindle cranks, like those from Rotor and FSA’s 386EVO standard.
This BB is compatible with 86mm frames, and also compatible with TREK T47 85.5mm wide frames.
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.
