Anti-Puncture Tyres At-a-glance

^ very interesting. Do look like the Marathon Plus solution which we know works pretty much 100%. The difference is that the 24c weighs in at 415g vs the 580g for the Marathon plus. They also make a 29c at only 475g.

Why did you have to show me those, I thought I was happy with my Marathon Plus 25c !!

are M+ only 580g.? in an older issue of Cycling + they indicate 708g for the 700x25...then 415g is much lighter...!

PS: i run M+ and no flat for 10,000 miles!!!!
