Venge / OSBB crank compatability

pedalbasher

I am looking to get a 2019 Venge frameset which has OSBB bottom bracket.

I'd like to run etap with SRAM Red22 exogram cranks. Ideally a quarq power meter.

Can anyone tell me my options? Will a standard BB30 crankset fit? This OSBB thing is confusing me.

Thanks!

I converted my Venge to 24mm Shimano using an adaptor. You should be able to do the same for SRAM. Wheels MFG may have something. Have a look on here https://wheelsmfg.com/specialized-alloy-osbb-tech

I had an original Venge with the ceramic bearings running 10 speed Ultegra Di2. They only lasted 3 months with hardly any use! So had a wheels manufacturing conversion done. They do a massive range. Just had a New Bianchi disc frameset built up and have used one on that to take Sram gxp cranks.

C-Bear do a BB that I reckon is what you need. Link below to Bike24 listing

If you want to look elsewhere it is the C-Bear OSBB61-GXP-R

Just be aware OSBB is a Specialized term and can mean many things even across their range and ages! I have an older Venge and had to get a new BB and went around the houses trying to find the right one. They used to go into a bare carbon frame but I think they have now put Alu cups in so the size may be different. I went with CBear for bare carbon as it was the only option available and cost way more than I wanted to spend.
make sure you know the diameter and width and check with a manufacturer would be my advice. Both Praxis and CBear were helpful.
