  1. Patrick Byrnes

    When purchasing an item like this, the thing that really makes the difference, is when you contact the seller for advice and they come back to you within minutes. Not only that, they (Hambini) follows up and makes sure that everything is cool. I’d have absolutely no hesitation in recommending Hambini, and his products.

    Both road bikes are now running Hambini BB. (BB386 and Trek T47)

Q & A

Is this bottom bracket compatible with the new winspace agile? mat asked on April 8, 2024

Yes, but I would suggest full contact seals if you are using it for offroad/gravel. It is a no cost option.

what is the ft/lb torque spec when installing the Hambini Racing T47 in a 2022 Domane BB Shell? Dick Spear asked on April 3, 2022

Approximately 30Nm. Technically, the bottom bracket will self tighten as you pedal. this assumes nothing is binding.
