Hello and thank you for the replies, I finally got a nano and I suppose I'll leave the derailers stock. I'm considering upgrading the tires first. from what I gather, it seems that panaracers, schwalbe marathon, kendas are much preferred here. What would you guys recommend for value and durability (I'd like to save money if possible)? I'm also looking into tubes, can I fit tubes with those tires? If so, which should I get? And finally, how hard is it to install tires and rim tape on your own (what tools would I need?) or is it better if I just have my local bike shop do it for me? thank you!
