Shimano CUES FC-U6030 9/10 Speed Double Chainset - 50/34T - 175mm

Shimano CUES offers high cross-compatibility within the CUES family and with certain compatible LinkGlide components, allowing 9, 10, and 11-speed shifters, derailleurs, cassettes, and chains to be mixed and matched. All CUES components use the same 11-speed chain and 1:1 cable pull ratio but are not compatible with older, pre-CUES Shimano groupsets from the Dyna-Sys or HG eras due to differing standards.

- CUES range of components for mid-grade riding styles offers simplified compatibility, versatility and durability
- LINKGLIDE technology is very durable, up to 300% more durable than current Hyperglide drivetrain and maintaining smooth shifting
- Industry leading HollowTech II cold forged crank arms have been evolved to increase rigidity, reduce weight and improve strength
- Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low
- Can be used with Shimano external or press-fit bottom brackets which allows for easier installation, adjustment, and maintenance
- Alloy outer and steel inner chainrings
- Steel chainring fixing bolts
- For use with LINKGLIDE or HG 11 speed chains
- 47mm chainline for 142 /135 mm O.L.D
