“Really light makes it easy to stash a couple in my saddle bag instead of carrying just a single spare. Seems to make the bike feel a bit more responsive as well”
“This might work in tyres up to 25c in width but did not work well in my 28c tyres. When inflating there is an area where the tube is joined and it is twice as thick, this created a 'bump' in the wheel that was visibly noticeable. When I took the tube out, it was 'overstretched' and very thin in the area around the join, elsewhere it looked normal. I think that these would need to come in a bigger size for 28c tyres rather than just saying they fit 23c~28c”
