I was looking at the sustrans site and seen the bowling to falkirk wheel route. Its going to be canal path, which i imagine will be gravel for the most part, my mrs is using my old mtb bike (im imagining as its canal path it will be mostly flat and easy for her(and me)) but I will be using a road bike with 23mm tyres which imnot sure of on gravel. To you reckon it would be ok on that bike? Mainly choosing it as it will be flat for the mrs.
