I keep a record of everything i do to my bike so i know how many miles stuff has done! I think i'd be wanting to get more than 3500 miles out of a rear though especially if its only road use. As i said, its only on the track that i have any issues about confidence. Most of my road riding these days is two up so mileage is more important than absolute grip becasue i ride a heck of a lot slower with Lynn on the back. I think the two sets of wheels idea might be the best one. |
