Hi, have the Marathon+ on my Trek 7.1fx at the moment got these fitted instead of the cheap Kenda's which came as standard,what I'm wondering is how much faster would I be on some lighter tyres,been looking at the Conti gatorskins thing is Iv'e done nearly 1000 miles now on the marathon+ and had zero pun*tu*es and am totally confident with them.As this is my 1st bike since being a kid have no idea how slow the marathons are compared to other tyres.btw my current average speed is only about 12-13mph.
