WTT: 175 SRAM GXP crankset for 170

[El Chupacabra]

Anyone have a SRAM GXP direct mount MTB crankset in 170mm that they'd like to trade for a 175mm set? Mrs C's bike is just a tad too tall with her dropper post at full extension, and I think a 170mm crank would solve it.

Her bike has a 175mm direct mount GXP SRAM Descendant 6K (aluminum) crankset.

I have a Race Face turbine cinch in 170 I could use, but it uses a 30mm spindle, and her bike is a PF92 BB, which kind of sucks for a 30mm spindle. (Very small bearings.)

Which dropper post is it? Is the dropper post bottomed out on the collar, or is the dropper post bottom out inside the frame?

It's a Brand X from Chain Reaction. It's bottomed out on the collar - it cannot go any further into the frame because of the collar, not because of something inside the frame.

Okay, just curious because I have successfully trimmed 10mm of the bottom of a Reverb for a customer.
