The SRAM crank is at least 160mm++ above. I believe it's 167mm
The lowest Q-factor os 147mm by campagnolo ultra-torque and shimano is 150mm++(can't recall). SRAM is the highest-> no surprise.....Taiwan made crank...what you expect
for the record, if anyone knows the Q-factor of a cannondale bb30 and cannondale alum crank, i would much appreciate that as well. i seem to be having some issues compared to when i ride my six13 with a 7800 crank. just curious. thanks....
If it is the Hollowgram crank you are talking about, I've seen them listed as 144mm. The DA 7800 is 146-147 depending on the source of the data (Shimano vs. Fairwheel crank shootout).
Sram cranks are 150mm and they bother my knee compared to my 7800 or 7900.
The widths I have are:
I measured my Red cranks in the garage and came up with 150mm. The Shimano 7800 and 7900 I have are both 146mm. This is measuring from outside edges of the crank arms. I mount the arms directly across from each other (not how you would want to ride it) and measure straight across. I *guess* it could be different when you mount the arms the way you would for normal riding, but I would doubt there would be any difference.
I'm really just trying to make sure that the Sram Red BB30 truly IS 145mm. Call me vain, but I want the group to be all matchy-matchy. I have some Hollowgrams that I can use too. (Go ahead and flame me Starnut!)
