Potholes and other pavement woes can be hard to take on a bike – they convert all of your hard-won forward momentum into up-and-down unpleasantness. You could cry to your local public works department — or you could take matters into your own hands with this awesome new bike technology that redirects the bump away from you. The Tortola RoundTail frame ($2,000) transfers the shock of bumps in the road to two hollow steel loops, which replace the conventional twin triangles, cutting vibrations by as much as 50 times.

The loops in the Tortola RoundTail frame force shock waves into a spiral, where their energy dissipates. Riders who took the RoundTail for as rugged a road spin they could find had no pain even after riding 50 miles. The same route made them achy after a measly two miles on a conventional bike. Sure, repaving the roads would be cheaper and more equitable — but with the state that public budgets are in, we’re not holding our breath.
