Changing tires & tubes is too difficult..
Hi. From my previous thread, I could get a 27-1/8 tire & a 1/4 tube. Thanks to all the people who replied to my thread. And I've encountered a couple of other issues...
Q1. It's a Panaracer tire. My previous tires would be at least several times thicker than this(I'm not sure the brand). The bike shop near my home said it's because the panaracer tire has a better quality, but I'm not convinced.
Q2. I didn't realize the tube is Schrader type. The previous one was Presta type, and the hole of the rim for air inlet is too small to use a Schrader type tube. It seems like many people enlarge the hole to fit a Schrader tube. But if I do that, will I still be able to use a Presta tube?
