I'm new here and thanks for having me. I've looked around a little and it looks like a really nice site. I have a tire question: I ride a Specialized Sirrus Comp with Mavic CXP21 rims. Tire size is 700X26c. I noticed on my before ride inspection, that my sidewalls are getting cracks from dryrot. So, now I'm in the market for new tires but 700X26c seems a hard size to find. What other sizes will fit this rim? I ride only on paved roads, someone got any tire recommendations? I currently have Specialized Turbo/Armadillo. Thank you for all your help.
