The Conquerors of Kona; the first generation ARC's were 3-times gold medal winners, victorious at the 2017, 2018 and 2019 Triathlon World ChampionshipsDevelopments in disc brake and tyre technology have meant that even the best needed to evolve to take advantage of the latest tyre technology and the frames able to accept themFor the past 3 years, working with their aerodynamic R&D partners Swissside DT, have been continuously testing the latest generation of disc brake specific aerodynamic rims, hubs and spokesThe result is a family of new, 20 mm wide (internal) rim profiles optimised for 25-28c tubeless tyres that have been proven by extensive lab and real world testing to enable lower rolling resistance and improved crosswind handling whilst achieving incremental reductions in drag, even over the original ARC designsAs the leading hub engineering force on cycling, DT continue to push the boundaries of what can be expected from a racing hub, the new DICUT 180 with 36 tooth Ratchet EXP is the lightest, simplest, lowest drag road disc hub DT have ever made and still just as reliable and easy to service as the legendary 240DT and Swissside's continuing leading-edge research into rotational drag and its effect on performance has lead to new, narrower Aerolite II and Aerocomp II spokes, unique to the ARC's these are what you can do when you design and make every part of the wheel and squeeze even more performance out of the system without the unproven reliability of less durable materialsThe front wheel comes ready for 12 x 100 mm thru axles, rear comes ready for 12 x 142 mm thru axlesMaximum recommended system weight: 110 KGWhen bought as a pair they will include both Shimano Road and SRAM XDR freehubs, rim tape and lightweight tubeless valvesWeights by rim depth: 80 mm: 1,820 grams a pair, 62 mm: 162 grams a pair, 50 mm: 1520 grams a pair
