The Shimano GRX 810 Double Chainset is part of the gravel-inspired range that is specifically engineered for riding on broken roads and mixed terrain where durability and a wider, 17T front range, is a necessity. The 48-31T ratio is optimised for tough riding conditions where you might need to spin an easier gear to carry the extra weight of your adventure packing equipment up steeper climbs or across rough surfaces.
Crank arms are available in three sizes - 170mm, 172.5mm or 175mm and the proven Hollowtech technology keep weight low without compromising durability.
I bought this for a bike build for a Mason Bokeh. Yes I've fallen for the whole gravel craze but after 20 years of commuting on 25mm rubber I can confirm 32mm is better and this crankset is super. Looks smart , nice colour, Shimano build quality. Was worried by smaller chainrings as used to 50-34 but its fine. You need the GRX front mech as its wider Q factor.
Direct swop from 105 without changing the derailleur despite the 17 tooth difference. It’s right at the adjustment limit so changing derailleur is recommended. Good quality for the price point.

From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
