DT Swiss HEC 1400 Boost wheelset

The Boost version of the DT Swiss HEC 1400 Spline DB 47 Carbon.

Super-sturdy, super-fast and yet lightweight, the HEC 1400 Spline wheelsets for e-bikes and standard endurance road bikes. The further reinforced version of the ERC 1400 wheelsets. The AERO+ rim, developed with the specialists at Swiss Side, paired with extra-sturdy spokes, the rear wheel with 28 spokes, and the tried-and-tested 240S hub. The lightweight 1739-gramme full-carbon endurance road disc wheelset: the DT Swiss Spline HEC 1400 Spline DB 47mm clincher with a 19mm rim width for tyres ranging from 28–47mm in width. The completely newly developed HEC 1400 wheelset series offers maximum stability combined with low weight and outstanding aerodynamics. The HEC 1400 Spline carbon disc wheelset, featuring a 47 mm high-modulus full-carbon Swiss Side rim developed by DT Swiss, is designed for folding and clincher tyres, with extra-reinforced hybrid spokes and the proven high-strength Ratchet Star rear hub technology.

DT Swiss Straight Pull Hybrid Spokes

To achieve an ideal balance between weight and stability, only the highest quality straight-pull spokes are used in SPLINE wheelsets. They are more stable than conventional spokes yet can still be trued and replaced using standard tools. The HEC wheelsets are built with spokes specially reinforced for hybrid wheels.

DT Swiss HEC 1400 Spline 47 Disc Clincher Rims

The rims, with a 19 mm rim width, are built for tough cross-country and gravel use and offer outstanding aerodynamics. On the HEC 1400 Spline C, the rims are made from high-modulus carbon fibre using a new resin. The profile, developed by Swiss Side and inspired by aircraft construction, offers the best aerodynamics. The 1739-gramme lightweight wheelset, suitable for both folding and clincher tyres, is completed by straight knife spokes.

DT Swiss Spline 1400 Disc Hybrid Hubs

The DT Swiss Spline Hybrid Road hubs, with their optimised hub shell and wider hub flanges, offer high lateral stiffness. Designed for straight-pull spokes and the proven ratchet pawl freewheel system, based on the DT Swiss high-end hubs with Swiss industrial stainless steel bearings, they are exceptionally durable and can be serviced and converted to Shimano, SRAM, Campagnolo and SRAM XDR freewheel bodies without tools.
