The Colnago G3X is Colnago’s take on the ever-growing Gravel trend. It’s purposefully built for both Gravel and Long Distance Road riding and features geometry that’s especially focused for Gravel, with longer chainstays, a lower BB and longer top tube. This brings the rider forward and ensures a more compact rider position with a lower centre of gravity for greater off-road balance and control. Shimano RX810 Gravel Specific Groupset with Hydraulic Disc Brakes Plus, the G3X is equipped with Shimano’s latest Gravel specific groupset (Shimano RX810 Mechanical) and gravel-specific tyres from Hutchinson at 700x40c to match the Frame’s enormous Tyre Clearances. And, the frame accepts up to 700×42 or 650bx47 sized tyres. Built, Tuned and Ready to Ride Rest assured that each bike is fully built and tuned by Wiggle’s team of qualified bike mechanics to ensure your bike arrives in perfect condition.
