School me on Colnago C60 BB

[velomonkey]

OK, the new BB for the Colnago C60 - as if there wasn't enough confusion in BBs - they come out with a new one.

So here is my question - Can you use a true BB30 crank in there? I'm talking Cannondale SISL2 - if so, what BB?

Mr RedRider..

The Cannondale SLSi cranks are great but unless they offer a longer spindle you will not have enough to clear the BB86 BB.
We've been using Rotor for those that want stiff, light alloy cranks upgrades on the V1R and C-60

Thanks - I actually reached out to Colnago over their Facebook page and they said, no, BB30 cranks wouldn't work either.


Thanks for the info. Good to know.

The C60 Threadfit is their version of BB86. It's designed for press fit cups with a 41mm OD.

So if anyone wants to: educate me on why if you're going the BB press route - why wouldn't you go press fit 30 and thus allow EVERY BB, versus press fit 86.5 - BB90 and all that stuff which is basically a non-threaded version of a regular BB.

As a big guy the one thing I can say is that BB30 cranks are a bit stiffer (the others are fine, but I lose 1/4 weight with Dale cranks and they last forever) though regular cranks are fine, too.

If you're gonna go press fit - be more inclusive not less - or am I missing something.

The only cranks that wont fit on that BB are "native" BB30 cranks designed strictly for a 68mm BB shell. So that rules out Hollowgrams and Specialized OSBB because their spindles aren't long enough. But, theoretically, any 90mm "universal" system crank will fit. That includes cranks with 30mm spindles which have their own proprietary BBs such as Lightning, Rotor and THM. BB386 cranks also fit with the adapter below:
