The Rennen Ultralite Mini Bottom Bracket is an engineering masterpiece. We set forth to develop the lightest and smallest bottom bracket in the world, but we did not stop there and made the bottom bracket adjustable.
The adjustable feature includes a bearing cup with a taper thread lockring/expanding shell design. This allows the user to precisely adjust their chainline. Once set we provide special tools to lock the cup in place and allow precise control over bearing pretension and chainline adjustments. Check out the installation video here.
