    • Slime Bike Tube Sealant is rated 4.0 out of 5 by 35.
      Rated 5 out of 5 by from It worked! Had slime fitted by Halfords a few months ago. Yesterday after cycling down a lane noticed a stick stuck to tyre. Pulled off and air started to hiss out, after a couple of minutes green slime could be seen and leak stopped. Cycled home 3 miles and tyre still inflated after 24 hours. Very pleased!

      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.
