Fitted the Tour tyres today, they measure around 5mm narrower over the tread pattern than the standard marathon plus tyres. No problems fitting them at all and the rubber seems slightly softer and grippier than the standard tyre. The tread is spread out more with slightly larger gaps between so hopefully those gaps won`t make them more vulnerable.
On the road( on a basically dry) 18 mile run, I sorted out as many wet cruddy areas and heaps of centre road gravel to see how they performed and I`m pleased to say that they did tend to stay more on a straight line than the original tyres as well as the standard Marathon Plus tyres.( the standard marathons have always performed well and been easy rollers but these new tyres don`t float on loose gravel as much.
The bike definitely feels more secure on the new tyres and looking at the tread on the edges I would feel a lot more secure cornering under cruddy conditions which is the norm where I live and I felt no extra drag from the slightly heavier tread pattern.
Out of interest on the Aurora the rear fork lugs are fairly shallow, there are tabbed washers that fit on the inside of the fork end but they only just enter the opening so it`s probably as well that the axle shaft has two flats and is a fairly tight fit in the fork ends. Might be a case for a purpose made torque arm or something(although there was no sign of any damage in the fork ends)
The rear wheel was very easy to release from the drop outs and by cutting the cable ties all the way up to the controller there was easily enough free play in the cable not to have to cut it and fit a connector(which only adds more places for problems and water ingress)and OH Yes! I always split the chain and get it well out of the way, takes 30 secs and really simplifies the job.
