Shimano GRX RX810 Hydraulic Flat Mount STI 1 Ring Crankset Groupset


11 speed. 8 pieces (GRX ST-RX810 Hydraulic STI levers with hoses, RX810 Flat Mount Hydraulic brake calipers - front and rear, BBR60, Ultegra: bottom bracket, RX810 1 ring crankset, M8000 XT Wide Range cassette, R8000 Ultegra chain and RX812 rear derailleur). Rotors can be purchased separate.

The new GRX Limited is the tried and true 11-speed mechanical GRX 810 series Groupset, brushed and polished into a classic silver finish for an extra-classy take on the quality, precision and durability synonymous with GRX. The Japanese brand says GRX Limited celebrates the long, illustrious heritage of drop bar adventure riding, the kind of cycling that inspired Shimano to design the world’s first dedicated Gravel Groupset. The Groupset has adopted the new hydraulic brake caliper design from Shimano’s recent updates to Ultegra and Dura-Ace. The updated design includes 10 per cent greater pad clearance, in order to reduce rotor rub, and a relocated bleed port for easier maintenance. There is a rich variety in the field of gravel bikes. Among those bikes, there are unique, handmade bikes crafted in steel, titanium, and aluminum that are tailored to meet their owner’s preferences. There we find aficionados who embody bicycle culture and builders who take pride in what they offer.

For the new GRX Limited, Shimano has created a special edition finish that embraces the beauty of aluminum. It perfectly compliments the efforts of the frame builders who blend the aesthetic form of their creations with the inherent beauty of their metal materials of choice.
