Under sized innertubes

The only thing that I think would make a difference is the tyre you're using due to the differences in sidewalls (I never had a puncture with my old der kaiser no matter what tubes I used in it). As long as they're pumped up to a suitable pressure for what you're riding I can't see you having a problem.

Besides, if you do get a puncture you've got loads of cheap spares right?!

Yeah - that's pretty awesome.

To be fair, most people on mods just crack on with a standard (Kenda/Halfords/Wilkos) 20"x1.75"-1.95" in the 19"x2.5" they run on the rear :P

That'll stretch the material much more than going from 2.125" to 2.3", so you probably won't even notice the difference.

Edit: ...Having said that, don't expect them to be great! Hahaha.

I ran poundland tubes in the front for a bit, they're great and don't puncture too easy.

Running them in the back of my mod was a mistake though, went through about 3 in a few hours : /

Running a 1.95 tube in a 2.5 is so much bouncier than running a 4.1 or whatever the kenda DH tubes are. Add so much life to your bike

Im no expert, but ill still assist.

I just use the cheaper tubes regardless. I get pinch flats all the time, so its better to have lots of cheap replacements, than having a not-so-cheap one with 10 or so repairs on it.

but the thinner it is, the more it has to stretch/expand.

and the more it has to expand, the thinner the rubber gets.

simple logic really.

just means itll be more prone to punctures.
