I want some new tyres for my Saracen mountain bike. I don't want mountain bike tyres because they slow me down too much around town. My friend bought some Kenda freestyle tyres and they look really good. I want some tyres that will mean i can accelerate fast and not have to pedal my hardest to stay at speed. Any recommendations? my tyres at the moment are 26x2.35 i think. All help appreciated!
