HGC 1400 Spline® DB 42 ROAD BOOST Hybrid E-Gravel Front Wheel Carbon 28″/700C

The HGC 1400 Spline® DB 42 front wheel is the poster child of the hybrid gravel wheel category from DT Swiss!
During the development of this elegant carbon wheel for high-end e-racing and gravel bikes with ROAD BOOST standard, the focus was on unrestricted, off-road riding pleasure. The lightweight system wheel for disc brakes is based on the DT Swiss Hybrid Endurance line and delivers outstanding performance even off the main road.

Enjoy speed and absolute control while riding off-road, on dusty dirt roads and through narrow forest passages. At the same time, the carbon fibre, Swiss engineering work of art impresses with modern materials and advanced manufacturing techniques. That’s how the medium-height carbon profile rim is able to combine a robust construction with high stiffness and low weight. The 28 reinforced DT Swiss Aero spokes allow the wide carbon rim to rotate around the solid 240 Spline® ROAD BOOST hub.

To benefit from more traction, grip and comfort in the cross-country hunt, the HGC 1400 rim harmonises excellently with modern wide gravel tyres. Excellent tubeless compatibility provides less weight, improved puncture resistance, and lower rolling resistance. When manoeuvring over narrow gravel trails, this ultimate wheel for e-bikes supports you with reliable control and safe handling.

The HGC 1400 Spline® Premium Hybrid Gravel front wheel is an excellent choice for all performance-oriented gravel riders who like to ride fast trails and rely on exceptional wheel handling characteristics.

Technologies:

• ROAD BOOST:
With the ROAD BOOST standard, the distance between the hub flanges is increased to improve stiffness and stability with a flatter spoke angle. This reduces the stress on the material by improving symmetry, which in turn greater durability. DT Swiss prefers the Road Boost standard for use on e-road bikes. With high loads from the driver and engine assistance, it better compensates for torsional forces and improves steering characteristics under load.

• TUBELESS:
All DT Swiss wheels are tubeless ready. The profiles of the DT Swiss rims are specially designed for tubeless use. The rim profile makes it easier to fit the right tyre and ensures a perfect fit. The tubeless system of the rim consists of DT Swiss Tubeless Ready Tape for sealing and a DT Swiss tubeless valve in a length that complies with the rim. When using tubeless ready tyres, it is mandatory to use a compatible sealant. However, it is also possible to use a conventional combination of tyre and inner tube.

• BEARINGS:
Thanks to years of experience, DT Swiss only uses durable cartridge bearings without bearing play adjustment. DT Swiss hubs are designed to have the optimum axial and radial bearing play when they are properly installed. The correct preload of the bearings to compensate for the clamping force of the wheel mounting system is the basis for a play-free hub with minimum friction.

• PRO LOCK®:
DT Pro Lock® prevents the spoke-nipple connection from loosening. In the Pro Lock® process, a special dual component adhesive is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and then hardens completely within a few hours. Re-truing the wheel is possible, yet it will cause a slight decrease in the adhesive power each time.
