Seido External bottom bracket T47 Pro

Our BB T47 are precision machined from aluminium and fitted with the highest quality bearings. They fit 30 mm axle cranksets with the included washers or can be equipped with our adapter kits to accept other bottom bracket axle standards. The BB sleeve has been designed to allow space for internal cable routing. Maintenance and bearing replacement are easy thanks to the accessible bearing rings, even when mounted on the frame. The outer seals provide extra protection for the already double-sealed bearings. Our BB PRO use 2 bearings 6808 (30 x 40 x 7mm, ID x OD x W).
