Increase your bike's performance with Shimano's PTFE Dry lube. PTFE suspended in the lube is used to reduce friction and therefore mechanical wear. It penetrates into hard-to-reach places giving maximum performance protection.
Strengths: Excellent lube, the chain flows smoothly.
Weaknesses: Collects some dirt. After 40-50km, your chain will be fairly dark.
Apply one drop per link, keep the chain moving for one minute and wipe out the excess. It's important the chain is 100% clean before application, otherwise the lube will be contaminated. Probably, it won't result in a noisy chain, but it'll stain any cloth it contacts.
I had a minor problem with the bottle. The nose stucks inside the top.
