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.
We have one large bike in the shop for test riding, and we're taking preorders on the March 2021 batch now. They will probably sell out before they arrive.
Available in two wheel sizes (27.5/650B and 29/700C) and two excellent colours.
The fourth batch of Kevin of Steel has 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.
