I purchased the 42 size and was upgrading from a 38. There is a difference between the two and the 42's do weigh a little more (when inflated) but the 42's offer great traction both on dirt and street. The tread pattern is great and they are durable. I've been having these tires for a little over a month and no flats yet. I dont expect getting a flat anytime soon.
I ride these tires on a CX bike on gravel, cement, dirt around phoenix and they handle well and absorb a lot of shock. They are quite big and do catch some wind though. The reflective whitewall is more profound than the pic shows which I like for city riding. I've seen several women glance at me and lower their shades will riding on these tires.
Great tire. Smooth and easy to gain speed. To my surprise tho, I found these tires are flippin Awesome on snow and Ice!!!! I mean 4 of snow and packed icw and snow. Amazing!!! Rode all over the place and my tail end slipped just once, but not much. Ill be buying again!!! Customer for life!! Used to make my own studded snow tires and what a pain in the a that was!! No more!! Thanks, Rob
