Can someone explain to me what the hell "Wide GXP" is all about?

Can I use these on a regular old GXP bb?

It says you have to use a "wide" clamp on fd adaptor with them...

What the hell is this nonsense all about?

Just a wider q factor

Same bb

Just a wider q factor

Same bb

why does this exist? i assume there is a reason or is this just sram being sram?

Because people thing they need it. Probably the same guys that buy tankinis. :banana:

Over time Q factors have gradually gotten more narrow and for many folks this is a good thing. For some however it gives hip or knee issues. Usually these guys mess with pedals/cleats to move the foot out some but it's a royal PITA.

Maybe this works better? It certainly is more simple than messing with pedals and long axles.

does it mean they'll work on 73mm bottom brackets now?

Also for MTB crossovers, who are for sure helping fuel road discs.

I wish they would make a narrow mtb crank other than the xx1

^ There is a Shimano XTR with lower Q.
