DT Swiss C1800 Spline Disc Brake Wheel - Front

The DT Swiss C1800 Spline Disc Brake Wheel - Front is built for riders who don't stay on pavement. It belongs to DT Swiss's Cross Road line, the wheel family the brand designed around muddy tracks, technical sections, and the kind of terrain that punishes a wheel built for smooth tarmac. This is the front half of the set, sold individually, with an aluminum rim, a centerlock disc brake interface, and a 12x100mm thru axle that mounts to modern disc-equipped road and cyclocross forks.

The rim is where the C1800 Spline earns its keep on rough ground. It measures 22mm internally and 26mm externally, a wide platform by aluminum road wheel standards, and it's tubeless-ready. A wider inner width lets you run tires at lower pressure without the sidewall folding under load, which translates directly into more contact patch and more grip when the surface turns loose, sandy, or wet. DT Swiss pairs that rim with its own tubeless sealant to help riders take full advantage of the lower-pressure setup — more traction through a muddy corner, more comfort over broken pavement, less risk of pinch flats when a rock or root catches you off guard.

Underneath the rim sits the DT Swiss 370 hub, running the Ratchet LN 18 engagement system. Where a traditional pawl hub relies on a small number of teeth catching at a time, the Ratchet LN design uses two star-shaped discs pressed together so every tooth on the ring engages simultaneously. The result is a hub that keeps working cleanly even after it's picked up grit and water — a real advantage on a wheel meant for cyclocross racing or gravel rides where the drivetrain sees plenty of both. It's also a serviceable system, which matters on a wheel that's going to see mud, sand, and standing water over a season.

DT Swiss hand-laces the rim to the hub with 24 of its own new aero II straightpull spokes, a spoke design the brand builds specifically to balance stiffness with low weight. That build comes in at 828 grams for the front wheel alone — light enough not to weigh down a cyclocross bike's handling, but with enough spoke tension and rim depth (23mm) to hold up to the sideways loading that comes with cornering hard on loose surfaces. DT Swiss rates the wheel to a 264-pound system weight limit, covering rider, bike, and gear combined.

As a front wheel only, the C1800 Spline is built to pair with a matching rear or with another disc-compatible rear wheel running the same axle and brake standard. It suits riders building or upgrading a cyclocross bike, a gravel bike that sees a mix of pavement and dirt, or anyone who wants a durable, tubeless-ready aluminum wheel that can handle wet-weather training without hesitation. It's not a wheel chasing aerodynamic numbers — it's a wheel built to keep spinning true after the road runs out.
