I want to buy myself a nice MTB quarq. I have a standard BSA frame so I'd buy the GXP version with external cups.

Thing is, if I ever change my bike, I'll be stucked with choosing among the BSA frames option. I know I could put a sleeve to adapt a BB30 frame into a BSA frame but it adds quite a bit of weight. Any way I could do the opposite? i-e adapte a BSA frame to PF30 or BB30?

thanks for any suggestions

The SRAM BB30 crankset works in a BSA frame with a conversion bottom bracket such as that offered by Rotor.

Alternatively just buy the GXP crankset and if you get a BB30 frame you just buy BB30 crankarms and swap the Quarq spider onto them.

Reading on the rotor bsa30 BB, they say its only compatible with sram 900 and 975 cranks, the MTB quarq is a sram s2275 crank... Would it fit?

I like the crank arm idea, quite dumb not to have thought about it myself.... facepalm

thanks!

I use bb30 X.0 crankarms with a rotor bottom bracket in a BSA shell. These crankarms are the same as those you get with a Quarq mtb crankset...just different graphics. 900 and 975 are the road crankset model numbers. They just don't list which MTB models it's compatible with.

Quarq are also super cheery and helpful in person... I'm sure you could give them a call for answers too.

@grover - Does your bike have a 68mm or 73mm shell?
