4iiii Power Meter Crankarm, Shimano GRX 810 172.5mm

Brand new in box 4iiii Precision single arm Shimano GRX 810 power meter, 172.5 mm length. These go for $450 if you can find them, I bought this in December for $514.15 including tax and shipping. The plan was to install in the spring, but I decided to order a new gravel bike in the interim, and this crank arm won’t work on the Easton cranks coming with it. Hoping to get most of what I put into it back out of it. I have the same one on my road bike, it’s a really nice power meter. This is also compatible with any of the Shimano Hollowtech II cranksets (eg 105, ultegra, dura ace, grx, xt, xtr).
