I was wondering what most of you or is adviced to run as the right innertube size for 25 mm tires on wide rimes like HED, Zipp or others. With a 25 mm on a wide rim getting wider then 25 mm would it be better to run 20 - 25 or 28-32. These are the most common sizes i see, what are you using?
The reason for asking amongst other is thatbi just replaced my conti force / attack in the 24/22 width to the new 25/23 width running 20-23 tubes. Didn’t rode a flat in 3 years. Flatted twice with the new size tires with the same old size innertube. Might be just coincidence, but i thought maybe it is the size difference?
