With its 40mm rim depth and a combined weight of just 1563 grams, the Shimano Dura-Ace R9170 C40 Centre-Lock Disc Clincher Wheelset is a fully flexible option for the rider who wants a high-performance wheelset as capable in the mountains as it is on the flat. The all-carbon rim construction is 40mm deep and 24mm wide, allowing for great aerodynamic performance and a wide and stable tyre base. Shimano has also integrated wide flange spacing for greater lateral rigidity and elbow-less spokes for a heightened degree of strength. Compatible with centre-lock disc brake rotors (available separately), this wheelset is a great choice for riders looking to make the upgrade to disc brakes.
For the hub, Shimano has utilised a strong 7075 alloy axle and a cold-forged aluminium shell to maintain durability and low weight. The freehub is constructed from titanium for the highest possible levels of durability.
