The most technically sophisticated competitive Gravel wheels out there; the GRC 1400's set new benchmarks in what you can expect from an all surfaces racing wheelset Working with the aerodynamics experts at Swissside, DT developed entirely new testing equipment and procedures for measuring drag and rolling resistance in order the develop the GRC's unique rim profile Freed from the constraints of UCI certification, the result is a blisteringly fast, 24 mm wide (internal) aerodynamic wheel and that has been designed from the ground up for 35c and bigger rubber The rims are manufactured using a method developed by DT to ensure continuous carbon fibres are aligned with the forces passing through the wheel, increasing strength and stiffness in use without adding weight DT's SPLINE series 240 ratchet hubs have long been a byword for reliability and low weight, with optimum spoke placement to allow improved bracing angles, improving lateral stiffness for no additional weight, a fast-engaging 36-tooth ratchet completes a premium package DT's straightpull Aerolite and Aerocomp spokes offer a highly optimised mix of low weight, stiffness and aerodynamic performance with DT's renowned reliability The GRC 1400's come ready taped for tubeless and with valves included The front wheel comes ready for 12 x 100 mm thru axles with adaptors for 15 x 100 mm, the rear comes ready for 12 x 142 mm thru axles, both come with Q/R converters The rear comes with both a standard Shimano 11-speed Road freehub and a SRAM XDR freehub included Maximum recommended system weight: 130 KG When bought as a pair they will include 6-bolt rotor adaptors, tubeless rim tape and valves Weight: Front 763 grams Rear: 871 grams (700c) or Front: 727 grams Rear: 835 grams (650B)
