Many bike stores don't really think through their lubricant selection, but when you sell bikes to city cyclists you really have to be careful. Most lubes out there assume diligence on the part of the rider. Every week you are supposed to happily clean then lube your chain and do the same again and again and again. Most of our customers are lucky to lube their chains once a month, let alone once a year. That means the lube that does go on the chain needs to stay on, but also can't attract too much dirt (because dirt causes wear). And that's really hard to pull off if you're making lubricants. We've been really impressed with the longevity and cleanliness of the Muc-Off lubes, more-so than any other brands. Recommended by our mechanics.
