Shimano Dura-Ace 9170 C40 Carbon Disc Brake Road Wheelset – Tubeless

Rim Material: carbon fiber
Wheel Size: 700c
Tire Type: tubeless

The inclusion of disc brakes on road bikes continues with its momentum and we are starting to see some very good, race-worthy road framesets and wheelsets. Component manufacturers at the moment are releasing groups with hydraulic offerings on its top-tier lines, and the brand new Dura-Ace ST-R9120 and ST-R9170 mark the first time we’ve got seen hydro disc brakes under the Dura-Ace moniker. Naturally, Shimano has expanded its wheel offerings, embracing discs and drawing heavily from its mountain bike development at the side of its proven road technology. The wheelset that we are most interested by is the Tubeless Dura-Ace 9170 C40 Carbon Disc Brake Road Wheelset as it pairs our two favorite revelations in road bike tech over the last few seasons, tubeless tires and road disc. Disc brakes have a large number of advantages on the road and one of the most biggest ones we will recall to mind right off the bat is the ability to run wider rubber. By repositioning the calipers closer to the hubs, the fork crown in addition to seatstay and chainstay clearance increases taking into account more room for big tires. Of course, as the rubber gets bigger, rims wish to increase their width too, to higher give a boost to the sidewalls and make allowance for a greater tire/rim profile for improved aerodynamics. These rims’ external width sit down at 24mm wide which Shimano recommends pairing with tires within the 23-32mm range for maximum aerodynamics. The lower rolling resistance and greater ride comfort are quickly appreciated over rougher roads as you’re taking by yourself classics. The depth of these full-carbon rims places it as an ideal all-arounder, perfectly suited to the puncheur or rouleur who needs a lightweight and stiff wheelset for repeated sharp attacks on steep cols and bergs in addition to nabbing a sprint in a small make a choice group on the end of a 5-hour slugfest. Its depth offers increased lateral rigidity and gives it enough aero benefit to lend a hand that attack stick if that is 30k from the line or a late race surprise within the flame rouge. Shimano off…
