I have nothing GXP, however, have:

160, 165, 170, 172.5mm all with 30mm axles that are long enough to fit BB86, BB386, BSA English, and Italian. Also, they come with spacers to fit BB30, PF30, and BBRight. If you're needing a BB to go with it, I'm pretty sure I have something laying around to work for you as well...

Have a 130 bcd 175 mm GXP if you change your mind

I have a Riken gxp with carbon arms. 175mm, 110bcd, and 50/34 rings. I have owned it since new and had it calibrated and 10k temperature compensation service performed in January.

Purchased 2 years ago and has 1500 - 2000 miles on it. Only reason for selling is that I’m looking to upgrade to a Bluetooth enabled Quarq.

$425 shipped including PayPal.

Let me know if you’re interested.
