My average from my computer is 15-16mph summer time and 14mph in winter. This is running Schwalbe Marathon 26x1.5 in summer and Schwalbe Snow Stud 26x1.9 during winter. I had Schwalbe Marathon Racers before and my summer time average was 17-18mph.

I'm looking to get a 29" tyred commuter with discs, racks and mudguards. Hopefully bigger wheels will roll faster too.

Choccy...
