Canyon just popped a new version of the Endurace back in stock and I'm a bit confused. Half way down the page they claim "With 33 mm of clearance, just fit chunkier all-road rubber and you’re good to go." for gravel riding.
But the bike is fitted with Shimano's 105 callipers. To the best of my knowledge, these only support up to 28mm tyres. What am I missing here - are Canyon suggesting you must swap the brakes to put in wider tyres...? Or are they tacitly accepting that slightly chunkier tyres can fit inside the 105 callipers.
