  • Slime Bike Tyre Sealant

    The Slime Bike Tyre Sealant is perfect for protecting your tyres on those bumpy rides! Suitable for all tyres, this easy to use product can prevent and repair punctures of up to 3mm using Fibro-Seal technology. This high quality sealant is also non-toxic and environmentally friendly and once installed into the tyre the slime remains liquid which will not harden or dry out. Overall this product is a fantastic solution for those annoying flat tyres!

    Rated 1 out of 5 by from waste of money had both my tyre's filled with this by Halfords, only had the bike on the road 8 weeks already a puncture. On inspecting the hole in the inner tube it was no bigger than that of a drawing pin so in my opinion this has failed in what it claims to do. Save yourself £7 and buy a repair kit and pump.

    Rated 5 out of 5 by from So far so good. Used this on my two bikes 6 months ago and I've had a puncture free summer. Very happy.

    Rated 5 out of 5 by from Slime Bike Tyre Sealant Much, much easier to apply if you have an inner tube with a removable valve core (I think the top of the bottle cap is a core remover but I used a special Stans tool). Put recommended dose of a 1/2 a bottle in each tube and they're fat bike tubes (4.6") but found the tube supplied wasn't a tight fit on the presta valve stem which caused some leakage onto the rim. Then took the bike out for a ride to make sure the gunk was evenly distributed. No effect on handling and more importantly no punctures - so far.

    Rated 1 out of 5 by from Complete Rubbish Absolute rubbish. Two very small punctures on different tubes. Had the right amount in each tube. Followed all the instructions. Don't waste your money.

    Rated 5 out of 5 by from fixed my pushchair! I bought this to fix a picture in my buggy tyre. Worked beautifully. A previous picture in the tyre was so impossible to sort out, as the rubber is very hard to get off and back onto the wheel. This was easy to use, and I had both tyres done within 10 minutes. I used about a quarter of a bottle per wheel. Best of all, I shouldn't have to worry about punctures again!

    Rated 1 out of 5 by from Disappointed! After reading lots of reviews from many sources, the general consensus was that this stuff does work so I bought 4 bottles as they were on offer. It was easier & cleaner than I anticipated to fill shraeder tubes - I used one bottle per tube on my fatbike (4" tyres) seeing as they reckon the same amount for moto x bikes. First ride straight after filling the tubes did result in the predicted wheel wobble whilst it spread around the tube but after that, you wouldn't have known it was in there aside from a slight weight increase per wheel, which on a fat bike you don't notice but you would on my xc rig!! After only 4 or 5 rides later, I plier out a small thorn (1mm hole) and the tyre goes flat, no green slime oozes out of the hole or anything, even when I rotated the wheel so the hole was at the bottom. My summary: complete waste of time and money - did not do what it says on the tin!
