Shimano GRX FC-RX600-1 Crankset, 165mm, 1x11-Speed, 40T, 110 BCD, Hollowtech II, Black

Available from Good Weather Bicycle when we last checked. Sold from the shop’s own store; the price there is the one that counts.

One ring, no front derailleur, nothing to think about. The GRX 600 single crank is the honest workhorse of Shimano's gravel line: ride it to the trailhead, ride it home in the rain, repeat. Shimano part EFCRX600111AXB0. 165mm arms, 40T, 110 BCD, Hollowtech II spindle.
