DT Swiss HG 1800 SPLINE 25 Boost Centre Lock Disc 27.5" Wheelset

The HG 1800 SPLINE 25 Boost Disc Center Lock 27.5" wheelset from DT Swiss for e-gravel bikes

The HG 1800 SPLINE wheelset in 27.5 inch fits (e-)gravel bikes and adventure bikes with Boost standard. HG stands for Hybrid and Gravel and indicates suitability for e-bikes designed for long gravel rides. The 370 SPLINE hub is optimised for center lock brake rotors and has a Ratchet LN ratchet freehub. Thanks to the 18 teeth, the pressure angle is only 20°. Wear is therefore particularly low and undesirable idling is minimised. The straight pull spokes are combined with Pro-Lock Squorx nipples, which, in conjunction with the Sleeved Joint rim, results in stable wheels.

E-Bike
This product has been specially developed to meet the higher loads of e-bikes.

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.
