The shifters feature the new internal routing for the cable outers and the complete weight has come down to 2481g (Manufacturer claimed). Key Features: Shifters: Shift cables are routed under the bar tape: re-development and positioning of the internal mechanism provides a faster lighter and smoother shift.

Brake lever pivots have been positioned to increase power and improve ergonomics when
riding on the hoods. Tunable reach adjusters enable custom fitments for all hands. Comes complete with silicon greased cables to further reduce shift friction and increase service life. Chainset: Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low.
