GT Grade: geometry compared to Trek
GT has come out with a really cool new bike, the Grade Carbon, which is designed to the "all-road" model for bikes able to handle paved roads, dirt, gravel, and trails. That starts with a bike designed with tire clearance first (35 mm), then with a frame design with compliance as a first priority. So GT builds into the frame exceptionally flexible seat stays to provide suspension for the rear wheel. It also has swept out handlebars, which I'm tempted to call novel. Tire clearance in the rear means long chainstays, and the Grade Carbon has by today's standards exceptionally long ones, at 430 mm. It also has a really slack head tube. One issue with "endurance" bikes is always geometry. Numbers are here: Here's a comparison of the GT Grade to the Trek geometries: The GT Grade is very close to the Domane 6, which is considerably more relaxed than the H2 (it's sort of an extrapolated H3). By the way, those diagonal lines show the effect of 1 ...
