The lube bottle applicator is the best I ever used and lets you put an even amount of chain lube across each link with no waste. It's a great product as I was hooked on paraffin wax based lubes, however, they were good for dry conditions and terrible in wet conditions. The Silca Synergetic Wet Chain Lube is perfect for all conditions and it provides a very smooth low friction protection for your chain.
Smooth and durable. Makes things a little quieter and very durable. One application lasted more than 350 miles. The only downside, it is oil, so, don't expect perfectly clean chain. It runs dirty especially for the first few rides. Be prepared to clean your chain after every ride. Eventually, it gets better, but don't expect the same as you see from a dry lube, such as the Rock n roll Gold
Concentrated oil that goes on well and precisely with the included applicator - I can imagine this little bottle lasts for over a year of frequent (3 times +) per week riding and in all conditions - easy to wipe chain after a few hundred miles of one use then re-apply and go again. Bought it for smoothness , quiet drivetrain and (compared with wax lubes) very little maintenance.
