Anyone try them? I read great reviews on the web but no mention of them here on the board. I am looking to replace my Cont. Touring Plus tires. I'm looking for a improvement in performance as everyone does but my main concern is flat protection. I've had the Touring Plus for 2800 miles and the rear one is going bald. I have only had one flat in all these miles. I would like something with this kind of protection. I know I can just get another pair of Touring Plus but an interested in something new.

My only experience is with Schwable Marathon plus 25mm. These things are beasts. I've been running on a set for 2-3 years now.Through snow, woods, thorn, gravel, glass, everything. These tires just refuse to get any flats. I cannot reccomend them enough. The only downside that I can think of is that when you first try them out, steering feels a bit heavier. But after a few rides you will not notice any of this.

I've had some quality issues with the rubber on these tires (there was cracking and perforation of the surface after a few months use on some tires). And while they had good flat resistance I found that the rubber compound was too hard and did not grip slick surfaces well. I donated my last few unused seca survivors to a coop.

I now prefer lighter kevlar bead tires and use these year round with no flatting issues. In particular, I recommend the gran fondo tricomp and rubino pro. Both can be purchased in the low 20s during yearly sales.

I had a Serfas Seca 700x28 on my bike for a while, it failed after a couple of months with a cut in the tread and I have sworn off Seca tires. My current favorite is the Panaracer Pasela PT folding bead, or the Panaracer T-Serv if you prefer a black sidewall. They run about $42 each in the US and are solid, tough and fast rolling.

I've had very good luck with Seca FPS 700x28s, but one 700x25 of a set I bought developed an S-bulge after a couple months.

a very different tire from the one the op is using.

I'm sure the Schwables are great tires. In case the Contis don't work out, substitute the words "Vittoria Randonneurs" and "recommend" and you've got my experience with four sets of 35 mm and 40 mm tires run on three different bikes over 10,000+ miles.
