Dt-swiss H 1900 SPLINE 27.5″ 30 6-Bolt Boost Disc Hybrid Wheelset

The DT Swiss H 1900 SPLINE 27.5″ 30 6-Bolt Boost Disc Hybrid Wheelset – Now with ratchet freehub
With the DT Swiss H 1900 SPLINE wheelset in 27.5″ you equip your e-bike with a durable, robust chassis. Thanks to the 30 mm rim width, you can ride wide tyres and low air pressures, which means you benefit from a lot of traction. The 370 Boost hubs for 6-bolt brake rotors are firmly connected to the rims via straight pull spokes and Pro-Lock nipples. This ensures stiff, durable and low-maintenance wheels. In addition, the rear hub has a Ratchet LN freehub with 18 teeth. This results in improved power transmission and more propulsion compared to the previous model.
Guidelines for Replacing E-bike Components:Before you replace components on your e-bike, please read through the guidelines for component replacement for CE-marked e-bikes/pedelecs with pedal assistance.

HYBRID
To cope with the higher loads on e-bikes, the hubs, as the heart of the wheel, have a higher wall thickness and larger housings than usual hubs. The spoke holes have been additionally reinforced. The freehub rotor is made from steel and is equipped with 24-tooth ratchets, which are made from special hardened steel. Heavy-duty axles and oversized hubs allow the wheels to work while bearing high loads. The rims have thicker rim walls and offer plenty of traction. The connecting element between rim and hub, the spokes, have reinforced spoke heads and are made of special steel alloys in order to withstand stronger external forces.

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.
