I am looking at keeping some spare tubes for trek mtb cycle - 26 * 2.1 xr tyre. I was wondering if the thorn resistant tubes really make a difference.
From what I read online, they are heavier and may not make much a difference, and not to mention twice the cost.
I ride mostly in city and plan to do some off-ride. I am wondering if the additional price and weight is worth it.
thanks in advance
