Rivendell says they cost a lot, last forever & don't get flats. 2 our 3 ain't bad (they do have a disclaimer on that). In May 2011, I installed a pair of 40 mm Marathon Supremes on my Atlantis. They were purchased "used" from a list member. Whatever use he put on them did not amount to much as I changed out the rear after over 7,500 miles & ONE (count 'em!) flat. It wasn't totally worn out but the moment was right. The front has had zero flats & looks good to go for another couple of thousand or so.
In the meantime, I got a set of 45 mm Marathon Plus with Smart Guard from another list member. They have zero miles; they just didn't fit his fenders. One of those is on the rear now. Being a bit wider and about double the weight (1,070 grams of steel & ruibber), I don't expect to have any further comment until perhaps 2014. When you think about the cost per mile and the flat resistance, Riv's statements are pretty much on target. dougP -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
