@DaveC - "Hi TT, have you tried swapping the knobbly tyres for road tyres? I have a pair of Schwabe Marathon Plus tyres on my MTB."
Just came across this after doing a forum search, as this is exactly what I'm considering. I use my mtb for commuting and I'm happy enough with my current 2" knobbly tyres, as the terrain demands it. However, having just spent a week touring, mainly on roads, and, more to the point, intending to do a 2 week tour of around 900 miles, (on good paths/roads) my thinking is that it would be a lot easier/faster if I fitter Marathon Plus 1.5's to my mountain bike?
What I'm not sure of is the suitability of these tyres to not so smooth tracks, such as WoL and canal towpath, or are they primarily for good, tarred paths? Also, what are the actual benefits of these in terms of speed, comfort, etc. over my existing tyres?
Right now I'm totally undecided as to whether I should simply go for the new tyres, get new wheels to save the hassle of changing tyres all the time (especially Marathon Plus) possibly getting dropped handle bars, getting those clippy pedal things, or... just buy a new bike? It's all very confusing...
Thanks.
