Has anyone had good luck running Spin-Skins with light weight wheelsets? Are they effective? How easy is installation? Are they noticable once installed? Thanks, mm
Used 'em extensively on my MTBs.TNC

But I've never used a set on my road bikes. Out here in West Texas, the Skins have worked quite well. In all our cactus, goatheads, mesquite, etc., they are not 100%, but they are quite effective. They weigh almost nothing. There is a new model called the "Duro" that I just installed in one of my MTBs that is supposed to last alot longer. I could get 9-12 months use out of one set of the older types. I've not found flats on my road bikes to be much of a problem, so I've not installed them in my road wheels. They do work, and if properly installed, they seem to last. I think they would last even longer in road use.
Getting ready to put them to torture testDog

I have some on order. I'm going to put them inside some Continental Supersonics, which are maybe the thinnest, flat prone tires ever made, with some Performance LunarLite tubes, and see what happens. When I first tried those tires, I got flats every single ride, then abandoned them. This should be a good test. If it works, the combination will be fantastic - 155g tire, 13g Spinskin, 50g tube, and flat resistant. I'll report back.

Kevlar tire liners to prevent flats.

Been running them for a season on a set of Special K's and Conti 3000's with great results so far. In fact I haven't had a flat while riding since I installed them. I have managed to tear a few tubes at the valve stem with overly agressive inflation and/or tightening the little nut too much. My wife swears buy them and I even put a set on the MTB.

Bottom line - flats are for other people now.

My only criticisms are that they don't seem to last realy long. You start getting breaks in the liner, but I may have spaced and installed one backwards. They are also a bit pricey, but way cheaper than tires. it is a little bit of extra work installing them the first time, but things get easier once they have adopted the proper diameter. I'd give them a conditional two thumbs up based on my expereince thus far.

How many miles would you estimate you've ridden with them with no flats? Also, how does your experience with them (experimental group) compare to your history of flatting previously (control group)? Notice any difference in ride?

I just got my set mail order, and will be putting them in tonight. Any suggestions?

Thanks.

Well, read the directions so you get them facing the right way.

As for milage I've probably logged over 2000 miles on them, been through a set of tires. the difference in flatting is most noticable when the tires are a bit worn and thinner, and also in the Fall when there are more thorns along the shoulder in the Bay Area. I don't really keep detailed logs so I don't have hard data, but if I stop for a flat it's because of someone elses. there is no difference in ride quality from what I can tell, and I'm pretty sensitive to subtle changes.

I can't really see any downsides other than the cost, extra installation concerns, and the 13 g. per wheel. They make a lighter/cheaper set, but I don't know much about them yet.

Put them in 2 different wheel sets last night, Ksyriums with AP Lights/Lunarlite tubes, Nucleons with Vittoria Ultras/LL tubes.

The Vittorias flatted like crazy when I used them a few months' ago (3 separate flats on one ride). That, combined with the fact that the Nucleons have a very shallow rim channel, making it extremely hard to change a tire, made me give up on both the Vittorias and the Nucleons (which are otherwise great wheels, but not as aero as the Ksyriums, IMO). We'll see what happens.

I'm going to use the Ksyiums/AP Lights for a double century tomorrow. That will be a good initial test.

The installation wasn't that hard. While at first it seemed it would be impossible to get them aligned down the middle of the tire, with all the yanking around getting the tire on, I realized that the company advice to pinch the sidewalls together to position the strip after mounting the tire and airing up a little works. There is enough stiffness down the middle of the strip so that you can feel it and move it with about 10 psi in the tire.

That center strip does add some stiffness, it seems, but feels mostly the same after full inflation. I couldn't tell the difference after riding on them, particularly in the Vittorias, which inflate to 160 psi. - rock hard!

I'm getting my American Classic lightweight (595/770g) clincher climbing wheels on Monday, and I'll install the strips on them with Continental Supersonics and LL tubes. If the strips work, that will be a fantastic, lightweight, combination -- light and tough. For those who don't know, the Supersonics weigh only 150g in 700c x 23mm, and inflate to 145 psi. When I used them last summer, they flatted nearly every ride, with even a sharp peice of gravel piercing through. If they don't flat now with the Spin Skins, we can certainly attribute it to the 'Skins.

If these really do work, they can revolutionize cycling. Imagine, no frame pumps, patches, extra tubes; lighter tires, tubes; more peace of mind; more safety; saving money on tubes, CO2's...

Here is the $100,000 question: Is anyone so confident of them that they would leave home their pump, tubes, and patches?
