Brilliant! Me neither.........compared to at least 10 in 6 years on over-hyped Pirellis.........and the ensuing 40kms of accumulated walking these unfixable bikes back home. It's a problem! Schalbe forever. The Trouble is that even walking these 35kg bikes 5kms (say) actually ruins the innertube because of the weight and the indentations of the rim on the fragile rubber...... so you have to replace the whole lot - not cheap.I really like the Schwalbe Pickup cargo tires. I have installed them on five bikes, three cargo bikes and one 40+ Kg bike. No flats on any of those frequently ridden bike in over one year.
