DT Swiss ARC 1100 DiCut Disc 62 Wheel - Front

The DT Swiss ARC 1100 DiCut Disc 62 Wheel - Front is DT Swiss's flagship aero road wheel on a disc-brake platform, and the 62mm depth sits at the center of the ARC 1100 DiCut Disc lineup, between the more crosswind-sensitive 80mm option and the shallower, lighter 48mm. DT Swiss didn't shape this rim in isolation — the NACA-inspired profile was developed with the aerodynamics team at Swiss Side, aimed at flat-to-rolling courses where holding speed matters more than shaving grams on a climb. The rim itself is hooked and tubeless-ready, with a 20mm internal width and 27mm external width wide enough to support the tubeless road and triathlon tires most riders are already running, without the tire distorting the rim's shape at speed.

At the hub, DT Swiss builds this wheel around its 180 DiCut hub, running the Ratchet EXP freehub system and SINC ceramic bearings. Ratchet EXP swaps the traditional pawl-and-spring design for a two-piece ratchet ring that engages around its full circumference, and the ceramic bearings cut rolling resistance a step further while keeping the hub spinning smoothly deep into a race effort. Twenty-four straight-pull DT AeroLite and AeroComp spokes connect hub to rim, and this front wheel uses a 12x100mm thru-axle with a Center Lock, disc-only brake interface — no rim brake or quick-release compatibility here. Weight comes in at roughly 730 grams for the front wheel, light for a 62mm carbon aero wheel, which keeps the extra rim depth from feeling like dead weight when you're accelerating out of a corner or closing a gap.

This is where the ARC 1100 DiCut Disc 62 is meant to live: long triathlon and time trial legs, flat road races, and any stretch of riding where a higher average speed for longer is the entire point. The 62mm depth is deep enough to cut through the air efficiently but shallow enough that it doesn't turn into a sail the moment a crosswind hits an exposed section of road — that tradeoff between the 80mm and 48mm options is exactly what DT Swiss and Swiss Side were balancing when they settled on this depth. Because the rim is tubeless-ready, you can drop tire pressure lower than you would on a tubed setup, which buys you more grip and a smoother ride over rough pavement without sacrificing the low rolling resistance a deep aero wheel is built around.

DT Swiss has been building wheels and spokes out of Biel, Switzerland since 1994, growing out of a wire-manufacturing tradition in the same region that goes back centuries — the kind of manufacturing depth that shows up in details like the 2-in-1 spoke hole and the precision of the Ratchet EXP engagement rather than in flashy marketing claims. It's a company built by engineers for riders who care about the numbers a wheel actually produces on the road, not just what it looks like in a catalog.

This is a race wheel first, not an all-day training or mixed-terrain wheel. The depth and stiffness that make it fast in a straight line are the same traits that make it less forgiving on rough, technical roads than a shallower training wheel, and the Center Lock, thru-axle, disc-only spec means it's built for a modern disc-brake road or tri frame, not an older rim-brake setup. For riders who've outgrown a mid-depth training wheel and want a dedicated aero wheel for race day, or for anyone building out a time trial or triathlon-specific bike, the ARC 1100 DiCut Disc 62 delivers DT Swiss's aero engineering without pushing into the 80mm wheel's higher price and greater crosswind sensitivity.
