What is the right tube?
I'm a relatively new and enthusiastic cyclist on a flat bar road bike. The bike came standard with 700 x 32 slicks but I wanted to get narrower tyres to go a bit quicker, esp. up hills. If I get 700 x 28 tyres will I need to change my tubes?
Would it be worth going even more narrow, say 25s or will that make the ride too uncomfortable?
