need a little help here. a friend is putting a QUARQ DFOUR91 with Dura Ace rings on his 2015 Cannondale SuperSix Evo.

i pulled the previous BB out...and it was one for a Shimano 24mm spindle. the BB housing won't take a new bearing since i pressed them out and measured the ID. its 37mm. the 30mm bearing is a 42MM O.D.

so it looks like i need to get a new BB housing for him. any suggestions? much appreciated.

All Quarqs are either BB30 or GXP. It may use Shimano chain rings but the crank system is that of Sram’s. So among all of the current Quarqs, nothing is compatible with the above wheels mfg bb. You need either a pf30 (if it’s evo hi-mod) or GXP bb from the same company.

If the Quarq DFour is the GXP version, you could try the Praxis Works conversion bottom bracket.
