Shimano GRX 800 2x11-Speed Gravel Groupset
Shimano's GRX range of groupsets has become the most popular option for gravel riding. Thanks for the wide range of options available for different types of riding as well as at different price point. GRX800 is an 11-speed groupset, equivalent to Shimano Ultegra road groupset. This groupset has a double chainset to provide a wide number of gears which is ideal for bikepacking and longer journeys or journeys on very steep terrain.
Everything is included in this groupset apart from rotors, which are specific to your frame.
Shimano GRX Cassette and Chain
There are no dedicated GRX cassettes and chains per se, these are simply borrowed from Shimano’s road and mountain bike ranges. That means no compatibility pitfalls, as long as you stay within the recommended tooth ranges and match the number of gears.
The larger 11-speed cassettes, such as the 11-34, will fit on a 10-speed freehub (or an 11 with an extra spacer), a bonus if you’re upgrading an older bike.
This groupset uses Ultegra CS-HG800 Cassette and HG701 chain. The cassette has a light weight minimal design sprocket carrier. Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load. Close ratio gearing allows a more efficient use of energy through finer cadence control. The sprockets are cut away and drilled to reduce weight without reducing rigidity.
- Ideal for: mid-level groupset for gravel riding, bikepacking, touring
- Groupset weight: 2662g excluding rotors
- 2x11-speed, disc brake, gravel groupset
- Chainset asymmetric four-arm design made from aluminium alloy

- Thick thin chainring tooth for chain retention without front derailleur, when riding with single chainring
- Pro-Tech bottom bracket has large, protected external stainless steel bearings attach directly to crank arms – for smooth, fluid performance and easy maintenance
- Cassette is made from 7075 aluminium, with a single block for large sprockets and five individual rings for smaller sprockets
- Super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum durability
