Clearance for 42mm tyres and lots of luggage mounting points

Cannondale has today launched its latest gravel bike, the Topstone. It’s an alloy framed machine with an all-carbon fork. It’s named after a dirt road near Cannondale’s HQ in Connecticut.

Cannondale has designed the Topstone with the same OutFront geometry as used in its SuperX cyclocross bike. OutFront uses a 55mm fork offset, paired with a slack head tube angle of 71 degrees (70 degrees on the XS bike). On the SuperX, we found that this leads to off-road stability, without losing steering precision. Transferred to the Topstone, this should give confident handling on a range of surfaces.

Top spec Topstone comes with SRAM Apex 1 and a dropper seatpost

The Topstone’s reach and stack are similar to the Cannondale Synapse endurance bike, so Cannondale says that it inherits that bike’s comfortable and sporty ride position. There’s plenty of clearance for 42mm tyres and you can fit 650b wheels and tyres if you want more air volume.

Cannondale has equipped the Topstone for longer off-road adventures, with mounts for a bag on the top tube and three bottle cage bosses. As you’d expect it’s disc braked and has internal cable routing.

Here’s Cannondale’s launch video.



Topstone specs and prices

The Topstone will be sold in three specs, with the top spec SRAM Apex 1 bike getting a dropper post with 55mm of travel and internal dropper cable routing. Gear ratios are 40 teeth at the front coupled to an 11-42 cassette. The bike’s wheelset uses WTB ST i23 Light rims on Formula hubs with 12mm thru-axles. Tyres are WTB Nano TCS 40mm tubeless ready. Price is £1799.99.

105 spec gets an FSA 46/30 chainset with an 11-34 cassette

Next down is the £1499.99 Shimano 105 variant. This comes with an FSA Omega ME supercompact 46/30 chainset and an 11-34 tooth cassette, for some really low range climbing gears. Wheels substitute WTB ST i23 for the Light version on the Apex build, although the set-up is still tubeless ready.
