I remember the early one well!expensive£25 each in 1988,gave the bike a real dead boneshaker feel,flat spotted too easily,and spun on the rim under heavy pedalling or braking......puncture protected tyres on the other hand have really improved especially the marathon plus range from schwable.
I watched the fitting instructions video last night. By the time you've fitted all the pins, seated them all, levered the tyre on bit by bit, reseated the tyre and pushed them in I think it would have taken longer than it took to fix all three p*nctures I had while riding last year.
the only place i can think of where punctures from hedge cutting is not a problem is london, where all the those farmers clean up after cutting their concrete hedges!
a universal problem all over the world is farmers not clearing up after cutting hedges, it doesn't puncture their tractors nor their trucks so why would they care when they could be doing something else?
I'm very tempted...forget the fitting aggro (3 hours!), think about all the crap you won't need to carry with you every single ride and never use.
No pump or inflator, no levers, no spare tubes, not tyre boot, no patches....no rucksack or caddy.
