Hi Stewie Chain-L works great in any condition for road and MTB. Being a wet lube, it is impossible to have a sparkling clean chain, but if applied and then wiped as clean as possible after is soaked in, it is possible to run the chain very clean. You can also give the chain a dry wipe after the ride with no need to apply more lube after every ride. Everybody prefers an ultra clean chain, but unfortunately that is impossible with a wet lube. A dry lube simply cannot do the same job for lubricating your chain and giving you smooth running, slick shifting, eliminates chain suck in really extreme conditions and staying in your chain for much longer. This will in the long run also save you some money on replacing chains and chainrings due to less wear causing friction. Let me know if you have more questions.
