Speed and tires. Help.
Hello fellow cyclists. I'm relatively new to the cycling community, well, the more "serious" cycling community.
I live in downtown Montreal, Quebec, one of the better cities for cycling in NA. Although there are plenty of bike paths, I just can't help but to bike on the road. I like to go fast and challenge myself as much as I can. I just recently bought a Giant XTC 2 2009 and have been riding it everyday for the past couple of weeks. I bike on average 25-35km a day during the week and anywhere from 50-100km a day on on the weekends. I haven't made any major modifications to the bike but feel that a couple might be necessary. I currently have some huge, stock Kenda Small Bloc Eight tires on the wheels and feel that they might be slowing me down considerably. I've clocked myself going on average 34 km/hr. I've reached a max of 53.5 km/hr on a relatively flat road with a slight decline (Parc St toward the city, for any of those familiar with Montreal). I know there are many factors to be considered but I feel that I'm not going as fast as I could be going.
Would changing my tires improve speed?
