CannondaleTopstone Alloy
gravel
01
Origin
The Topstone Alloy brings the core ideas of the Topstone gravel range — KingPin rear flex, dropper-readiness, wide tire clearance — to a more accessible aluminium platform. SmartForm C2 Alloy is shaped to provide some vertical compliance at the rear through the same seat tube flex principle as the carbon model, delivering a gravel bike that can genuinely take on rough roads without the full-carbon price tag.
