Details
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.
- BallisTec carbon frame with Kingpin suspension
- Lefty Oliver Carbon gravel fork, 30mm travel
- SRAM Force/X01 Eagle eTap AXS HRD 12-speed group
- HollowGram 23 carbon wheels
- HollowGram SAVE bar-stem
- Integrated Cannondale App connectivity
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Shifting Performance
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Customization
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Dependability
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
