GT Grade Carbon Pro Gravel Bike 2020
Combining compliance and efficiency with off-road speed and top-notch components, the GT Grade Carbon Pro Gravel Bike is highly versatile machine. It has the full gamut of mounts for luggage, bottles and mudguards, including on the fork and seat stays so it can be loaded up and used for long distance adventures. Alternatively, when stripped down and with the fork’s flip chip in the 55mm offset position, the carbon frame and Triple Triangle design make for a fast and fun bike for shorter singletrack blasts. The frame has clearance for 700c tyres up to 42mm wide, although the supplied WTB Riddlers are a good, fast-rolling all-round option at 37mm. The WTB rims are tubeless-ready, so conversion is quick and simple to take advantage of fewer punctures and lower tyre pressures.
Shimano’s Ultegra Di2 electronic based groupset eliminates poor shifting due to contamination, lack of lubrication or cable stretch and offers instant, accurate shifting at the touch of a lever. A wide range of ratios is available thanks to the combination of a 46/30 tooth chainset and an 11-34 cassette, with the 2x system allowing for smaller gaps between the gears than on a 1x setup. Equally impressive are the Ultegra hydraulic disc brakes that help keep control in all conditions.
