Hey folks.
I have a Pre-Owned Sram Red Aero Crankset for sale. It is a 10 speed, 53/39, GXP Crankset. 172.5mm arms.
These can be used for a Tri-bike, Time-trial or road bike.
This was on my Crit Bike, and then on my time trial bike. Rings work perfectly well, no skipping, or sloppy changes. Always changed my chain every 2800 miles. Always maintained and oiled correctly. I don't know how many miles I have on It but I used it for two seasons.
This Crankset is one of the lightest and stiffest crank sets you can buy, and is only 21 grams heavier than the 2017 SRAM red. Super light, super stuff, super Aero chainring. This is the same chainring that Fabian Cancellara, used, and Boonen.
Crankset has obvious signs of wear, to the face of the chainring, and slight rubbing wear to the crank arms. It's used, but it was never abused. To give you an idea I weigh less than 140 lbs 5'9", so I'm not a sprinter.
This hasn't been abused at all.

Im asking $95 Shipped in the United States. PayPal only, Local Pickup Knock off 10 bucks.
Feel Free to PM me with any questions. I'll try and answer as well as possible.

Thanks and Ride Safe!
