I have a maxxis minion 26 x 2.4 presta rim and i have a maxxis minion that is 26 x 2.5 scharaeder rim i want to carry one spare with me that will fit in both wheels - but i see most tubes are 26 x 2.2 - 2,4 presta ( not up to the 2.5 ) or 26 x 1.75/2.5 Schrader Tube ( wont fit in presta )
is there a presta tube that is 26 x 2.2 - 2.5 ? or a presta that cover the 2.4 and 2.5 range??
and ideas would be great
i see continental makes a Continental 26 x 1.75-2.5 Tube (42mm Presta Valve)
but got bad reviews with many valve isues and punctures.. any thoughts
Rubber stretches, I use a 18-23mm on my road bike while using 25 or 28mm tires. Or 2.0-2.25 tubes on 2.35 tires. It's not that big of deal. Plus, a smaller tube takes up less space while you're not using it. It is for emergencies for that matter.
I ran a 2.0-2.4 tube in a 4" fat tire for 2 years before I had to replace it, so a 2.4" tube will certainly accommodate a 2.5" tire. Id get a presta valve adapter for your Schrader drilled rim. Now you just need to carry one 2-2.4" presta tube. Boom
