tube size question.

[JAllen]

So I'm currently running Panaracer T-Servs 26x1.75 on my main ride. I was given some old still in the box tubes sized at 26x1.90-2.125. Can I/should I throw those in when the time comes?

the 26x1.90-2.125 will fit assuming you can stuff them in and not pinch them upon inflation. since you have them, definitely go ahead and use them.

Put about 5-10 psi in there so you can go around both beads to make sure nothing is caught before you pump them up.

when the time comes to replace, get the smaller size. it is much easier to deal with the right size tube (similar situation on my wife's commuter)

Thanks for the input. I'd rather not risk it getting pinched and blowing up. I might see about trading with a friend of mine to get the correct size.

Once it's in there is no issue. The pinch issue comes during installation. if guy can trade do it otherwise now you know the challenge at hand
