Mountain Biking - bye bye to flat tires..

What do you all think about anti-leak strips (I have no idea what to call the things in english but Im pretty sure you get the idea)?

Used them for a while now, and they do work great, no flatties since.
However, I do wonder wether they significantly slow me down or not, since they're pretty heavy. I just ride recreatively so I dont keep lap times or anything, soi I wouldnt know they effect of the added weight. It doesnt bother me as far as the feel of the hbike is concerned.
I heard someone say the other day that the only real weight you have to watch is that on rotating parts.
I can now ride trough thorny bushes forever without getting a flat tire...
Does anyone here use them? Do they slow you down badly?

Are you using Spinskins (http://www.warwickmills.com/01spinskins.html) or something more like Mr. Tuffy (http://www.roadbikereview.com/pscWheels/Rim,Strip/SBS,MR.,TUFFYS,Mr.Tuffy,700c,Tire,Liners/PRD_97410_2507crx.aspx) ? I would consider the spin skins if you are worried about weight .. they work very well, though they are a bit more expensive.

I have no idea, I just got the only type they had at the LBS and I threw away the packing. they're orange and about 2 mm thick...

Tire liners.....I had some of those several years ago. They certainly stopped
the flats......for awhile. When they got some age on them (3 yrs I think) THEY
started giving me flats. Had the devil of a time getting them out of my tire. They
were all cracked and stuck in there.

i've used tire liners like mr tuffys and 2 other brands and they do work! especially against thorns and the like so that the only flats i ever got came from snake-bite.

i use the on my commuter/touring bike.

but they do add some considerable rotational wieght which is the worst kind... so i currently do NOT use them for my MTB XC race bike.

basically it's a trade-off... if you're racing and need every few seconds of advantage then the weight penalty is usually not worth the flat-reduction benefit. it also depends on the race length and the terrain -- if it's a race where getting a flat means you're out, maybe the tire liners are worth it??

but for recreational riding or for weekend tours you'll never notice the weight - you might accerate 1/100th of a second faster or beat your identical twin on a climb by 1/2 second, but you really won't notice.

i recommend them for everything except gram-counting racers.

I found this http://www.rlaenterprises.com/cycling/spinskins/index.html

I have tried them and they really work!
Been using them for the past 2 years - nop flats!

Typing too fast,
I mean No Flats with the Duros!!!!

either they lie about the weight or these are a bunch of ridiculously light tire liners.....
Mine weigh 200 grams each by the feel of it.....
Gonna get me a pair of those!:beer:

Hey Knifun have you seen the review of Spinskins on mtbr.com?
They don't get a good write up. I bought some about 8 months ago and I have still not put them in. Are they really that good, or will they cause even more flats?

Art - they are really that light!

Specialized is selling their air liners for 10 bucks.

Mr. Weasel,
I believe the product they were referring to was the original "Kevlar" version. I too did not like that product. For the road, they didn't even last 300 miles before completely disinegrating. I wrote the company and really bashed their product. They said there is a new liner coming out and would I like to beta test the product. I said sure. They sent me the new Dura Liner (made of a plastic that is the same composition as the spokes in SPOX wheels). These are FANTASTICO!!! I tested them per the companies recommendations changing them out at 3,000 miles. They look brand new!!! In over 10,000 miles, I have not gotten any flats!!! I have even pulled staples, shards of glass, pins, nails from my tires (I live in So. Calif where the bike lane is the neighborhood trashcan) and nothing has penetrated these liners. I have even gotten a couple of the local racing teams to use these on their training clinchers. I do not recommend the Kevlar version, but HIGHLY endorse the Dura Liners!!!!

The liners are also very lightweight!!!

Hope this helps.

How about EarthGuards?
Since Slime is difficult to get into Presta valves, I have Earthguard liners on my tires.

Looks like Earthguards are very similar to MrTuffys. I saw them at a few Internet sites and they look almost identical. They are only available for mountain tires. Duros are still your best bet.

Are you using Spinskins (http://www.warwickmills.com/01spinskins.html)

Spinskins, tire liner, slime it dont matter,if you do not get the glass out in time it will penetrate,I had spinskins after 30 miles flat tire.

Way to bump up a 6 year old thread.
