Topstone Carbon Lefty is a gravel bike to beat all gravel bikes. Dual suspension makes this the most off-road capable and on-road comfortable road bike ever made. We paired our proven, super-light, and effortlessly simple Kingpin rear suspension system with our cutting-edge, built-for-gravel Lefty Oliver 30mm gravel suspension fork—meaning better control and even more comfort. A refined geometry and rider position deliver an experience that’s stable, composed, and comfortable without losing that spark. Go further, ride longer, charge harder.
Topstone Carbon Lefty comes with smaller diameter, higher-volume 650B x 47 tires for even more off-road ability and on-road comfort. It has plenty of places to store gear and water, with a multi-position mount on the downtube and more on the top tube, seat tube, and under the down tube. Additional well-thought-out features include Speed Release thru-axles, a rear fender mount, and easy internal cable routing via DirectLine (including internal dropper post compatibility). In short, the works.
More Give. More Go. More Lefty. A gravel bike to beat all gravel bikes. Dual suspension makes this the most off-road capable and on-road comfortable road bike ever made.
