Flats vs Slime(13 posts)

Flats vs SlimeDjudd
Sep 25, 2001 2:12 PM
I am famous for flats and though riding for my whole life changing a flat on the road is still a chore (I've tried everything, even had my college cycling coach personally sit me down and give lessons on the intracacies of fast flat changing to no avail, in this area I am just dyslexic). Two years ago I got a set of "slime" tubes. I was skeptical, but I found they work. I'm not climbing Mont Ventoux (anytime soon) so the few grams of added weight are negligible. Does anyone else feel as enthusiastic about "slime".

That stuff is crap and it's not just a "few grams" - the damn tubes are heavy as sin. It's a crime to put it on the diameter of the wheel where you not only get to lug it up the hill but you get to rotatioanlly acclerate and deccelerate it.. Once you do get a good enough tear in the tube and the stuff leaks out you can forget trying to patch that tube. The chemical is nasty.

Try some Spin Skins - the wifey swears by them and never flats. Also, don't let your tires get super thin. It also helps if you try not to run over stuff.

Spin Skins? I've never heard of them, what exactly are they?

Kevlar belts bonded to a cotton type of fabric. place them between the tire and tube to reduce the occurence of flats. they aren't cheap (about $35 for a set) and they don't last as long as I'd like, but they work. Weight penalty is 14 g. per wheel. Ask for them at a qualtiy LBS, but make sure you get the right width for road (sizes are: road, touring, MTB).

I have been using for about three months an no flats. You have to follow directions carefully to work. Also have Mr. Tuffy on commuter, everything bike. Have used them for four years and only one flat a year. Tired a sewup with slime like stuff over 25 years ago. Cost then was 35 bucks more then good car tires. One flat and it did nothing. Tire to repair and it just got all over everything. Worst cycling purchase I have ever made.

I tried this on my MTB when I got a particularrly bad series of flats. It didn't work at all. I still flatted. This was on my college commuter and I didn't care about the added weight. I wouldn't think of using this on a bike that I am using recreationally or competively.
also--could be that you were having a problem with tire or tubeChris Zeller

setup. Often once you get your tires set right you won't have any problems for a long time. Sometimes-- a sharp object inside the tire or a repeat of incorrect tire pressure or incorrectly seated tubes will cause a rash of flats. Once you get it right, this will end for a while. This could have happenned to you and maybe incorrectly attrubuted to slime.

Yeah, something like a little piece of wire from trimmming a cable can get lodged in a tire and you flat over and over again. I don't use Slime - I just get to deal with it when it fails for others and they ask me to help -- before I realize that Slime is involved. Realize that it can't fix every type of flat - just the small annoying ones. Even a tire repair place for a car will charge more money to fix a flat if a Slime/Fix-a-flat product has been used. Been there, done that.

hate Slime - it works only marginally and seriously messes up the guts of presta valves over time.

I use Specialized AirLok tubes. they are self-sealing but with a less viscous sealant which does not mess up the valve. I've had tubes that had 8-10 sealed holes in them by the time I caught a thorn that actually caused a flat. weight is much less than Slimed tubes.

have not had good experience with Spin Skins either. one actually caused an abrassion flat on my MTB by getting all bunched up in a section of the tire. it was recognized by them as a problem a few years ago - possible they've refined their design.

Spin Skins cause more flats than they prevent. I've followed the directions to a T and have had at least 6 flats from interior abrasions caused by the SS liner rubbing up against the tubes causing leakage. I should of sent them back to the manufactor but I had thought for $35 they would work....NOT! Took them out and the flats are gone.

Never had an abrassion problem on wifey's bike or mine. We don't do flats - she doesn't even carry a tube or a patch kit (I know, foolish), but she says she has me.....

is heavy. doesn't seem to really seal up flats after a puncture though for MTB weheels it might.
