Syn Lube

The King of the Hill. The Original Synthetic Petroleum.
The first lubricant ever formulated specifically for mountain bikes.
Synlube ATB features the highest water-resistance rating, which means it stays on the chain
through mud and grime where waxes and dry lubes would flake or wash off.

Blended with a detergent polymer additive package that eats dirt particles, Synlube ATB results in friction-free lubrication in the worst conditions. Corrosion resistors protect the chain for long life.
Repeated applications create a barrier coating on your chain that will not wash off even through the harshest wet-weather riding.

ATB is also useful in lubing pedals and cables for foul-condition riding, by keeping water and corrosion out and friction low.
ATB has a positive polar attraction to metal, which means that it's best to apply when the chain is clean and dry for best performance.
It is non-toxic and packaged in recycled and recyclable bottles.
