Ritchey SuperLogic bottom bracket – 68 x 110


High end, lightweight steel axle BB from the king of minimal performance design

In stock


The Ritchey SuperLogic bottom bracket was designed by Tom at a time when his bikes were the cleanest designed, and fastest MTBs on the planet. Available with steel or titanium axles, these are the steel axle version and the 110 mm axle is ideal for a double road crank or a triple with a low Q factor (such as Ritchey’s own Logic compact crank!). The cups are very minimal with the sealed bearing unit pressed into them, this means in theory you should get a great deal of life out of them assuming your BB is threaded precisely. The sealed units can be removed and replaced too. Installation is with a standard ‘Shimano pattern’ splined tool with a lockring for the non-drive-side cup.
