I began cycling last summer. I bought a Trek 1.5 2 months ago. I've replaced the tube 2-3 times in each tire. Question 1: if I buy tubes online, should I care about weight or wall thickness? Question 2: are the tube liners I see online worth the money ($10 for gel - $45 for kevlar type stuff?) ?
I typically ride popular routes, so I don't think the environment is contributing to excessive wear. I assumed this is just a part of the fun.
Thanks for the help. I hope to be a regular.
