Bike maintenance rookie here.
I was buying some spare tubes a couple of weeks ago at Y's Road in Okachimachi (did they change their name from Ueno Classic?) when I encountered the following dilemma: My tires are 700x23, and they had Panaracer tubes in 700x18-23 and 700x23-27 sizes. Which one do I get?
I asked a clerk and he advised me to get the smaller ones as they'd be easier to install, and indeed they were (my previous spare was the larger size, which unfortunately had a hole that had escaped notice). But I wonder, is there any trade-off, like shorter lifespan or lower safe air pressure? I've put about 250km on it in the last two weeks and it feels fine so far.
Thanks.
