OSBB to shimano adapter help

Postby c0ugars » Wed Jan 02, 2013 14:11 pm

Hi

I'm looking at buy a SL4 frame but want to use my Shimano chainset with it. but the frame comes with a OSBB bottom bracket. Does anyone know what adapter I would need to use to make my Dura ace chainset?

Thanks for any help.

Any BB30 to BSA adaptor. It is a BB30 shell?

But I would look at the KCNC BBs that fit the BB30 she'll and work with Shimano cranks.

No idea.

See Parktools.

I've just ordered the same frame from Primera cycles in Bornemouth. I looked around the Internet and YouTube about the different types of adapters. Realised that it isn't simple so have asked the bike shop to install it for me.
Some of the adapters fit with the OSBB bb and some replace it. However they all need decent tools and some skill.
OSBB is not the same as BB30. It uses the same approach of press fit but I think it is narrower.

As Morrisje says OSBB is not the same as BB30. Probably easier to get it fitted at a bike shop. If you want to go it alone then Wheel Mfg kit is probably as good as anything

The alternative would be the new Praxis adapter which according to their website is now available to fit OSBB. This is a nice piece of kit (have the pf30 version) but haven't seen the OSBB version yet.
