So, are any of these "new wave" tubes any good?
We carried 2xtubes each on our ATM ride and that takes up a LOT of space when you've got 50mm tyres so I was going to replace the spare tubes with Tubolito or Aerothan or whatever but if they're not very abrasion resistant or fail as soon as you use them then there's no point.

I think that as a spare tube they are okay, but I'm sure that a butyl tube can withstand a bit bigger glass shards or small stones. At first I had the impression that the tubolitos are gonna be a bit more flexible and thus avoiding being punctured by pieces that penetrate your tire , but now I think its actually the other way round and normal butyl tubes already offer enough elasticity

so I rode my tubolitos for their first long ride yesterday and what can I say, i got a flat. the tubes already thinned a little where the holes for the spokes are and are starting to bulge a little, not as crazy as clockwork_killa had on the 2nd page, but I thought a 20c tyre would "hold them toghether" nicely. so these tubes will go in some spare wheels as I don't feel comfy now riding them on the streets.
