At home on the rough but surprising on the smooth, the Titanium Tempest is a gravel bike at heart but still light enough to cover the miles on the road. Using relaxed geometry, a supple titanium frame and plenty of tyre clearance, it's still capable of offering all day comfort off road. Mounts for mudguards and panniers make this a contender for multi-day adventures too.
