The hottest all-road/gravel/flashpacking bike around! It's incredibly versatile, covering a huge swathe of road and off-road riding. Curve's stable of ultra-endurance riders have tested the heck out of this bike, and it's been dialled in to perfection.
Available in two wheel sizes (27.5/650B and 29/700C) and two excellent colours.
The fourth batch of Kevin of Steel has almost the same planned spec as the previous production run - heck, it worked pretty good last time around. Please note that spec is subject to change due to availability.
