Advice on a replacement BB

siddy1972

I have a Colnago with the threadfit system. The BB is ready for replacement, I’m a bit torn on which way to go. I could get the CeramicSpeed T45 which is designed for the shell (questionable benefits on drag I know, but should fit well). Or a Hope technology screw together job that fits into the Colnago adapter cups.
Anyone got any experience or advice on either of these options?
Thanks.

pimping with ceramic speed is cool.


but a waste of money.

Have only ever used the Hope version for PF-30 BB with hollowtech cranks, was beautifully machined, fit well and has lasted many years without issue. It wasn't cheap as far as BB's go but still cheap enough for me to agree with david37 that ceramic one is very cool but also a waste of money

Ceramic BB,s are really not worth it. Personally haven't got problem with bog standard hollowtech or similar. If you want confirmation on ceramic BB,s watch hambini on YouTube, he's pretty vocal.

Thanks all. I’m sure you’re all right. It wasn’t really the ceramic part that I was attracted to (I do think this is mostly marketing gumpf)- it’s more about the way it integrates with the frame. What I’d really like is a stainless version of the T45 bottom bracket- but you can’t have everything I suppose. Still not sure what to do...

My experience with WheelsMFG has been excellent. I probably fitted a dozen or more last year and not one has come back. my personal experience of using them has been great too. Dead easy to fit, creak free and when the time comes to replace the bearings it's dead easy.

Are you supposed to fit the small washer that fits in the recess on the non drive crank (Shimano)?

? there's a dust seal and there are some small spacers incase you need them.

The one that came with the original Shimano cranks.
