Q & A
You could swap the end caps out to take it down to 24mm and give you the versatility but it's not a modification I actively suggest or warranty.
This won't do the job. You'd need to email in and a special can be built up for you.

Beautiful product. Quality is a quite a few steps ahead of the rest.

This works really well, it is a big improvement over the wheels mfg unit I had in before. Installation was a breeze with the recommended tool.
In his YouTube you will see small bits of Hambini’s engineering knowledge. When you email him, you get customer service from an Engineer and a very good one. It’s a completely different experience to dealing with a bike shop. Yes it’s expensive but the alternative (Ceramicspeed) is just as expensive and you don’t get anywhere near the same level of customer support.

Fantastic service and a Jewellery quality product 10 *

I tried fitting this and initially ran into some issues with the frame. It was not flat and required machining. I took it to my local bike shop to get it fitted, they faced the frame and then fitted it to the required torque spec which they claimed was extremely low.
I’ve had it on for 6000km and it has not missed a beat. I would buy another one in a flash. Well made, technical support second to none. Just make sure you read the instructions. The average bike shop doesn’t seem to have a clue.

Very beautiful and spins incredibly well. This will, without a doubt last for a long time.

The mechanics at my local shop were visibly excited about this BB. When I picked up the bike they insisted on unshipping the chain and spinning the cranks–which kept going for a hell of a long time–while they grinned and giggled.

Best BB in the biz IMO!

Upon dry fitting this BB, I instantly realised my $5k bike frame had a far from flat BB face. I got that rectified, fitted it and I’ve had it for coming upto 10,000km. Faultless performance
