Aerodynamics performance and improved drive rigidity.

Most advanced component group of all time: The Shimano Dura Ace WH-R9170-C40-Tubeless Clincher Rim, Disc-brake Wheelset

Two forces combine to slow down riders: air drag and inertia. DURA-ACE R9100 wheels are designed to combat these forces through aerodynamic features and reduced rolling resistance. Two new 28mm wide C60 and C40 rim platforms bring a stiffer wheel to enhance forward and side-to-side (lateral) power transfer and, with ultra-light carbon rim heights of 60mm and 40mm, are also designed to reduce air resistance. This allows Dura Ace R9170 C60 wheels, in a real world scenario, to save 16W over Shimano’s current DURA-ACE 9000 C50 wheelset. C24 wheels complete the DURA-ACE lineup giving riders three rim heights to choose from (60mm, 40mm and 24mm). Selected wheels are available as tubular or tubeless clincher rims with road E-thru axles (12mm).

Engineered for the next generation of race bike, DURA-ACE R9100 offers top-tier performance across numerous configurations. Available with either Di2 electronic or mechanical shifting, for the first time, riders now have the option of premium DURA-ACE hydraulic disc brake performance. New Shimano technologies further integrate the DURA-ACE as a system, including a new power meter, while riders further integrate with their bike through new E-Tube wireless connectivity. Shimano’s Rider Tuned philosophy and customization of the bicycle’s function also expands with a wider range drivetrain that now includes intuitive Shimano Synchro Shift control.

TECHNOLOGIES:

OPTBAL Spoke System
The OPTBAL rear wheel spoke system features 21 spokes - 14 on the drive side and 7 on the non-drive side. Cassette spacing in today’s wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel.
