The wheels are lighter and more aerodynamic than the previous R9270 generation, and are made for the wider 28 to 30 mm tires that are currently used in the peloton. They were developed with the riders from Alpecin-Premier Tech and Fenix-Premier Tech and with triathletes like Kat Matthews.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Much lighter<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>C36:<\/strong> 1,170 grams per set (was 1,350, 180 grams lighter)<\/li>\n\n\n<li><strong>C50:<\/strong> 1.302 grams (was 1.461, 159 grams lighter)<\/li>\n\n\n<li><strong>C60:<\/strong> 1.389 grams (was 1.609, 220 grams lighter)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The weight gain comes mainly from new ones <strong>carbon spokes<\/strong> in two profiles (Aero and the flatter Super Aero) and an improved rim construction. Per wheel, Shimano chooses its own rim type and number, depending on whether the wheel needs to climb, be all-round, or remain rigid in the sprint.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1920\" height=\"1281\" src=\"https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin.jpg\" alt=\"Renner from Alpecin-Premier Tech gives feedback to Shimano employees alongside a race bike during a test in Spain\" class=\"wp-image-3339\" srcset=\"https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin.jpg 1920w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin-300x200.jpg 300w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin-1024x683.jpg 1024w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin-150x100.jpg 150w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin-768x512.jpg 768w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin-1536x1025.jpg 1536w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-alpecin-18x12.jpg 18w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption class=\"wp-element-caption\">Testing with the pros from Alpecin-Premier Tech in Spain.

New is that the bearing cups are now replaceable and the seal is better waterproofed. In a test with simulated rider and pedal weight, the new hubs rotated according to Shimano with <strong>30 percent less resistance<\/strong> then wheels with plain bearing patterns.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The entire series<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>C36:<\/strong> spoke wheel, 18 spokes front and 21 behind, 29.4 mm outer width.<\/li>\n\n\n<li><strong>C50:<\/strong> allrounder, 21 spokes front and rear.<\/li>\n\n\n<li><strong>C60:<\/strong> For flat rides, sprints and sprints, 24 spokes at the rear for extra stiffness.<\/li>\n\n\n<li><strong>C99 (front wheel):<\/strong> 99 mm high, 16 Super Aero spokes, 792 grams, for time trial and triathlon.<\/li>\n\n\n<li><strong>Thick rear disc:<\/strong> 987 grams, the equivalent of the C99.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1920\" height=\"1281\" src=\"https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix.jpg\" alt=\"Renster from Fenix-Premier Tech consults with Shimano technicians during a bicycle test\" class=\"wp-image-3340\" srcset=\"https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix.jpg 1920w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix-300x200.jpg 300w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix-1024x683.jpg 1024w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix-150x100.jpg 150w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix-768x512.jpg 768w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix-1536x1025.jpg 1536w, https:\/\/cyclingreview.nl\/wp-content\/uploads\/2026\/10\/shimano-dura-ace-wh-r9370-test-fenix-18x12.jpg 18w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption class=\"wp-element-caption\">The female riders from Fenix-Premier Tech also took part.

Shimano has not yet announced any Dutch prices; they vary per country and model.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Our perspective<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A C36 weighing 1,170 grams is seriously light, and that Shimano is finally committing to 28 to 30 mm tires is exactly what riders want. The fact that Shimano is sticking with tapered bearings is typical of Shimano: they roll smoothly and are easy to adjust, and with the replaceable cups the biggest drawback (worn cups) is solved. The price is decisive, because competitors like Zipp, Roval and CADEX are in the same class.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source: <a href=\"https:\/\/media.shimano-eu.com\/nl-BEN\/267433-shimano-launches-new-dura-ace-wheel-lineup\/\" target=\"_blank\" rel=\"noopener\">Shimano Benelux<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Shimano is renewing the Dura-Ace wheels.
