WELDTITE Cycle Tyre Sealant - Temporary Puncture Repairs - Pressurised Latex to Repair Two Road Tyres (700 x 25c), 100 ml

This worked AMAZINGI have tubular tyres, got a puncher, and the side wall split about 15cm, and the valve was leaking a little bit.It sealed the whole tyre for over 2 hours and held 80 psi charge for the bike ride home.I was shocked to see it worked so wellBuying it again now.

Good size could fit in bottle holder, I've put mine in side bags for emergency use

Not used it yet but makes me feel more confident about going out knowing I have it to hand

Says what it does on the tin!

10 out of 10

Did not work. I got a puncture 5 miles from home, i followed the instructions, this did not inflate the tyre and the foam made no difference to the puncture. I had left my mini gas pump and spare inner tube at home because i had purchased this product, i was forced to walk my bike 5 miles home.

I had this kit in my bike bag for around 8 years. Then, it finally happened and I got a puncture and the tyre went flat. So, I rotated the flat tyre so the valve was at the 12 o'clock position, and dispensed all the foam into the valve. Got on the bike and started to cycle and voila, it was OK! I cycled another 5 miles to get back to home, and this was on rough gravel track and bounced up and down a lot of kerb stones as well. Filled my 27" by 1.75 mountain bike tyre. Delighted with this product and saved all the faff of conducting a roadside repair.

Having punctured my back tyre 7 miles from home, this little beauty sealed the inner tube and reflated the tyre will no fuss or mess. It is not a permanent fix but will comfortably get you back home or to the nearest bike shop.
