The Topstone Carbon 2 AXS SmartSense is a carbon gravel bike for riders who want to go further off the beaten track, in more comfort and with fewer things to think about.
At its heart is the Topstone Carbon frame with Cannondale's Kingpin suspension, a simple pivot that lets the rear end flex to take the sting out of rough gravel and rutted tracks without the weight or upkeep of a shock. Proportional Response construction tunes the carbon layup and geometry to each frame size, so the ride feels right whatever size you're on, and the downtube StashPort with its StashBag gives you secure storage for tubes and tools.
The 1x12 SRAM AXS drivetrain pairs Apex AXS shifters with a GX Eagle AXS T-Type rear derailleur and a huge 10-52 cassette, so there's a gear for the steepest climbs. SmartSense brings an 800 lumen front light and a Garmin Varia rear radar and tail light, all run from one removable battery, which makes this a properly capable bike for winter commutes and long days alike. WTB KOM Team rims and 45mm Vulpine tyres round off a build that's ready to explore.
