1) It says to pump to 100 psi, I was only able to reach 90 on pump. I can bend it slightly with my thumb on side of tire. I’m kind of worried and not sure if it’s properly inflated. I have ridden it and it drives fine though.
2) It has 7 gears in back (cassette) and 2 gears in front. Shows L or H on left and 1-7 on right side near my handbar. What is the ideal ratio for flat road? I have it on 1 in front (assuming 1 means L and 2 for H) and have it on 3rd gear from top. Please advise.
3) Has some rust as shown in photos, what’s recommended to spray it with?
