Inner tubes. On my cross bike I use 28mm tyres to commute and 32mm cross ones for riding around in dirt. Inner tubes generally say 18-25, 23- 28 or 28-42. Which are the best ones both my tyres? Will the 18-25's just stretch up to 32 without issue?
The reason I've not just gone straight for the 28-42's is they can feel like fitting a mtb tube into a road tyre and I'm constantly worries about pinching them.
