Well, I should say just riding around the city, maybe 100 miles maximum. I will be building up a Steelwool Tweed this winter and bought a set of Hope Pro 3 hubs (36H) which I wanted to use, laced to Mavic CXP33 rims. I read a lot of pros and cons about these rims for loaded touring but since I only weigh 140 and will not carry more than 20 lbs. on a good day, it appears they should be sufficient. I would like to put some Panaracer Pasela 700 x 35 tires on the CXP33 rim, is that workable? Would they be alright for hard packed trails and crushed gravel or are there other tires that are more suited? I'm trying to set it up for comfortable riding on the road traveling at a reasonable speed but some off road as well. I also read that you need to use long stem valves as they are an aero rim, any recommendations on a tube?
