Q & A

Hello Hambini, Will this BB solution work with the BB30 Campagnolo "Over Torque" crankset models such as Comp Ultra? This crank was only made for 11 speed, (it is nothing like Ultra Torque ones with Hirth joint and pre-fitted bearings on the axles). It has a kind of regular looking 30mm axle - however the preload and fitting the non drive side crank seems a little unique. thanks & regards, Paul Paul McCutcheon asked on April 8, 2024

It will depend on the DBCA of the crankset. If it's more than 90.5mm then it will work.

Will this fit "regular" threaded bb's? I am trying to mate an old s-works crank to a new sl7. Need a 30mm (BSA30) that builds as litte as possible outside the shell. Simen asked on October 17, 2022

This won't work with an SL7, you'd need the BSA30 https://www.hambini.com/product/hambini-racing-bsa-bottom-bracket-30mm/
