I don't think much of Serfas' "FPS" anymore.

Not since yesterday right after lunch. I walked past my bike sitting in the back at work, and noticed
a small light brown object on the tire. I got closer and realized it was a small grass thorn. Probably just stuck to the tire I thought. I brushed it off and pssssssssssssssst, there goes my air. If Serfas Flat Protection System can't stand up to a common grass burr, what good is it?? My confidence in these tires is blown (no pun intended ),,,,BD

The tires are Serfas Drifter "dualsport" 2.1's, on a urban ridden mtb.

I have NEVER encountered any tire, tube, or sealant that can stand up to goathead thorns.

Glad we dont have those goat buggers in Ohio.
I run 28c Serface tires with the flat protection for 2 seasons and I like them.The Serface seats seems to work good for me,untill I can afford Brooks leather.I heard down in Texas,those goat-heads will flatten a car tire.

Ride those on a fixed gear. You can skid for weeks. So many layers of rubber before you just blow out.

+4!

I might add that I've yet to run into a sealant that can seal much of anything (they do a good job of ruining your momentum though). Not to mention that they have one hell of a stench if they've sat around outside too long too. YECH!

Ugh. It probably made 15 individual punctures before all was said and done, and an additional 10 to your hand when extracting it

You can't go walking around on the sidewalks of our neighborhood without picking up some of those buggers of one kind or another. Might as well stay home and stick pins in yourself - or ride a bike.

Stan's NoTubes Sealant for mtb tires is the cat's meow, allows the use of standard tires and rims without tubes at all. I've ridden thousands of hard, off-road miles with the Stan's system without a flat. It makes for a lighter setup than tubed tires or the much heavier (and much more expensive) UST system, provides greater traction and ride quality than tubed tires because you can run very low pressures if you like without worrying about pinch flats, gives better tire selection than UST because you can use virtually any standard mtb tire........probably a subject for another forum, though-

Nope, one tiny pin hole. That's all it takes. I owned them for two years and they've been on several bikes
without a problem. I guess they only have the flat proof material at the very center of the tread. I am tempted to cut them open and see if anything is even inside the tire carcass.,,,,BD

Tuffy's seem to work ok for me - as long as you catch the thorn pretty close to the time you picked it up. Unnoticed and left embedded it will eventually strike home.

When the LBS sold me the 28c Serfas tires,he noted the Kevlar belt in the inside road contact area of the tire.I guess the sidewalls are fair game to those thorny little monsters.Is there tires with Kevlar on the side walls ?
Best Regards this Holiday,
Dan

Not sure, but I would buy them. Where I ride is no place for a flat. Well, past a certain St. it's okay, but still. This thorn was well within 3/4" of the tire center, inside one of the negative tread areas. I'm only glad I caught it at work, with tube patches on the shelf, and an air tank handy.,,,,BD

The Serfas Secas are cheap, grippy and ride nice. I've had a few flats, but I've also flatted gatorskins. The only tire I never flatted were Bontrager hardcases.

Ditto on the Bontragers.
I have 1.25" Serfas Barista slicks on my MTB. They seem tough enough and are much lighter than the Armadillos I had. But then, we don't have those evil looking burs around here.

Are you attempting to insinuate that Goatheads.com is an axis of underwear evil?

I just got an apologetic response, and they asked what they could do for me. I declined any
help. Like any business, they probably would've offered me something they make. "Yeah, I'd
like a new set of tires!" One week later,,,,,pssssssssssst, lol.,,,,,BD

Well,I guess in a roundabout way Goatheads.com is promoting the boll weavil,(sworn enemy of the cotton plant).
Under every lycra,spandex,whatever cycle outfit is our friend and supporter Mr.Cotton.If these pricker plagued peddlers order in these mail order weavils,it could be devastating to the casual cv riders.This plague on the cotton plants would give guys on bikes new meaning to the phrase"drop outs".
Did you know a can of,"FixaFlat"will fit perfectly in your water bottle cage?
Thanks for the great research in cv forum this year guys,
Holiday Greetings,
Detel Dan

Sheesh, now the rear went flat. Was fine when I got home Friday night, and didn't ride it all day saturday. I did move it out into the yard a few feet so I could get into the garage easier. Went to move it back last night, and it was flat. So far I have had more flats with these, than a set of normal tires with regular tubes, lol.,,,,BD

I will be changing them. No sense in using the drifters with thorn proof tubes.
