Rondo Ruut TI Gravel Bike 2021
With its refined and aesthetically pleasing full titanium frame and accurate components, the Rondo Ruut TI Gravel Bike offers performance to the discerning rider during the quickest and most demanding rides into the wilderness.
The frame makes use of high-grade 3AL-2.5V titanium to gift a springy, vibrant and comfortable ride characteristic whatever the technicality of terrain. Titanium is also highly fatigue resistant to guarantee years of hassle-free service over the most rutted of off-road paths and trails. A full carbon fork partners the frame and lends positive steering response and extra vertical compliance to the build. This fork makes use of the adjustable TwinTip concept to alter its offset and height to donate either racier handling or a more relaxed riding position. The frame and forks are compatible with either 700c or 650b wheelsets and accommodate broader tyres for increased cushioning and grip over challenging tracks.
HUNT Rondo wheels use a lightweight but resilient alloy rim that has a 25mm internal width to better support tyres at lower inflation pressures when tackling loose and rocky surfaces at speed. Shimano GRX gears change smoothly within a wide range of ratios so that the ideal cadence can always be found. At the same time, the hydraulic disc brakes, also Shimano GRX, give confidence-inspiring stopping power whatever the riding conditions.
