Schwalbe Doc Blue Professional Tyre/Tube Sealant

My go-to tyre seal. 60ml is perfect for two 700c wheels and I’ve been puncture free for years. Thin nozzle for squeezing directly into the wheel with the valve unscrewed. My tyre pressures stay good for weeks. Top product.

I top it up every 4 months and so far it’s worked well. The rim tape wasn’t sealed properly on my new bike and for a few weeks they went down overnight. Topped them up and they have been fine since.

I’ve never tried tubeless before but after reading reviews apparently this stuff is a good compromise of some puncture protection and value for money.The stuff has gone into my tyres and time will tell if it works as designed. At the end of the day I only really expect it to cope with smaller thorns as those are the most annoying. Anything larger which it won’t fix would also be a problem if you run inner tubes in my view so it’s a no brainer.

Brilliant and wouldn’t be without it. Fantastic product and does exactly what it says on the tin. Been using this for 12 months and no punctures that weren’t sealed anyway

Basically a repackage of Stan's Fluid in a convenient package. The small bottle can be used for both the initial setup at home, and carried in your backpack for trail side refills.As with any Stan's, you must make sure you shake it vigorously before use.

Does job well

Perfect product did the job, fast delivery and a great price.Well Done

Use it for puncture proofing and have had no punctures for some time
