Take a new cobbled stone course and assume the following

1. Route is 350 km consisting of 50% maximum difficulty cobbles, 20% mud, 30% smooth asphalt (including a velodrome finish)
2. Weather is a constant 'medium drizzle'
3. Two riders of equal performance

Allowing current rules for road bike optimisation and a mountain bike optimised (but with 26” wheels) for such conditions.

Which would be faster?

When you get a puncture, do you have to change the tube or can you pick a wheel off a support car? My road bike handled some pretty rough road in Nagano but it punctured on the way home. My MTB has never punctured yet.

bigger wheels roll over stuff more. put your money on the road bike. less fatigued rider will win.

Flax frame for the road bike? They seem to thrive on cobbles.

Tempting to say the road bike, but an MTB could fly over those cobbles.

Correct answer?

Professor Head, could you tell us the correct answer, please?

I thought it might be my slightly modified cyclocross with fenders (to keep the rider clean, you know) touring road bike, or an all carbon Kluoto Kross, or a Surly Crosscheck.

The race was set up so that both bikes would have a perceived equal opportunity of winning and the winner depended on your argument. A lively debate would have produced a majority answer. Alternatively, any TCC volunteers for a cobbled stone ride?
