BBright is based on a 30mm axle.
BUT, lots of companies make BBs thatâ€™ll fit in a BBRight (Cervelo) frame. I currently have a BB from Wheels Manufacturing set up for GXP, which could be used for Shimano by swapping out the left side bearing. Could also go DUB with the right bearings.
OP was under the impression that they could only use a crankset with a 24mm axle.
Not sure how you came to that conclusion. All they said is that itâ€™s currently set up for 24mm spindles. In fact, given the admitted confusion about BB standards, I would guess the OP couldnâ€™t possibly conclude it would only take a 24mm spindle.
Post #14 basically says that the OP wants 150mm cranks.
Post #17, OP basically says that 150mm cranks are only available with a 30mm axle and not a 24mm axle.
In post #19, OP is perplexed that BBright is based on a 30mm axle.
I am pretty sure that if you ask the OP what their thought process was, it would fit my analysis.
Cool. You win.
