DT Swiss says that the 24mm internal rim width provides optimal support and lowest drag with 40mm gravel tyres.Hooked rims for safety and aerodynamicsWhile other brands are increasingly offering hookless rims, both new DT rims have hooked beads, following the brands move to return to hooks from hookless in its latest CRC wheels. DT Swiss says that it believes that hooked rims are better than hookless for safety and ease of use.It also says that its modelling and wind tunnel testing suggest that hooked rims are more aero than hookless, contradicting Zipp, Enve and other proponents of hookless rims. DT says that, with the launch of the new rims, its entire road and gravel wheelset range is now hooked.As well as low drag, DT Swiss claims that the new GRC 50 rim also has lower steering moment than a range of competitor gravel wheels the force that is exerted on the rim by crosswinds at different yaw angles. For an off-road rider, the ability to keep a line with less effort is likely to be an important feature of a front wheel in particular.The rims are built using a patent-pending process, which DT says provides a high quality finish out of the mould without air pockets or excess resin, thus avoiding the need to lacquer them, in turn saving weight.Weights and pricesYou can buy both rims laced to two different grades of DT Swiss hubs and with different spoke grades, with the different specs designated the GRC 1100 Dicut and the GRC 1400 Dicut.The higher spec GRC 1100 Dicut wheels have a 180 Dicut hub with a Ratchet EXP freehub with 36 points of engagement and are laced with 24 T-head spokes to prevent spoke rotation. The front wheel and rear non-drive side use DT Aerolite II spokes, with Aerolite Comp spokes in the rear wheels drive side.Laced to the 1100 Dicut hub, the GRC wheels have a claimed weight of 1,350g for the 30mm profile and 1,567g for the 50mm depth. That makes the GRC 1100 Dicut 30 wheelset some 252g lighter than the previous generation GRC 1400 Spline 42 gravel wheels, which we reviewed in 2021 and which are now discontinued.Both depths of GRC 1100 Dicut wheels are priced at 2,299.98 / $2,990.80 / 2,499.80.The GRC 1400 Dicut wheels have a 240 Dicut hubset with the same Ratchet EXP freehub, while the 24 front and rear wheel spokes are T-head DT Aero Comp II. Wheelset weights are 1,421g for the 30mm depth and 1,631g for the 50mm profile.The GRC 1400 Dicut wheels are priced at 1,864.98 / $2,399.80 / 2,049.80 per set in both depths.Both hubs are available with freehubs with Shimano 11-speed, SRAM XDR and Campagnolo N3W compatibility, as well as Shimano Microspline now a requirement for gravel bikes with the latest 112-speed Shimano GRX.Plus e-bike specific HGC 1400 Spline wheelsetIn addition to the GRC wheelsets, DT Swiss has also released the HGC 1400 Spline wheelset.
