DT Swiss A 1800 SPLINE 30 Center Lock Disc 27.5" Wheelset

The DT Swiss A 1800 SPLINE 30 Center Lock Disc 27.5" wheelset - streamlined performance for small road bikes

With the A 1800 SPLINE 30 Center Lock Disc 27.5" wheelset from DT Swiss, small road bikes get an aerodynamic upgrade, too. The 30 mm deep aluminium rims reduce wind resistance by approx. 15 watts at 45 km/h, and they are also tubeless compatible. The 370 SPLINE hubs are designed for center-lock brake rotors and straightpull spokes. The rear wheel has a Ratchet LN freehub with an 18-tooth disc and an engagement angle of only 20°. Wear is therefore particularly low and unwanted idling is minimised, which means you can get up to speed quickly. The extremely durable DT Aero Comp Wide spokes cut through the wind and have been equipped with self-locking aluminium Pro-Lock Squorx nipples for even more safety.

Technology:

Intended use - Category 1
Suitable for predominantly paved surfaces.

Pro Lock
The nipple thread is coated with two-component adhesive to increase the durability of the wheels. It can still be re-trued several times without any problems, but the adhesive strength decreases slightly. The connection between the spoke and nipple cannot loosen by itself.

Ratchet LN
The Ratchet LN freehub is used to convert DT Swiss 370 hubs with pawls to a ratchet freehub. The advantage, compared to pawls, is the significantly larger contact surface with improved frictional connection. The seal attached to the freehub body, and not to the hub shell as usual, makes the freehub body easily replaceable. The modular design allows free selection of the engagement angle (18, 24, 36 or 54 teeth) and of the freehub body.

SPLINE
Straight pull hubs, straight spokes and strong rims result in a durable wheel. It can therefore be reliably used in training and competition.
