K2ThePeak: This lube was highly recommended by the best bike mechanic that I’ve used. Key is a little goes a long way. For example, maybe five-six drops on your chain, then basically crank a cycle or two whole holding a shop cloth against the chain. It leaves just enough lubricity to have you drive train running smooth and quiet. Yet, not wet where you pick up tons of road grit. This is key especially on long rides like centuries. Great product.

D. Freisinger: This lube is the best! It greatly improves shifting performance and keeps your chain clean. I put one drop on every link roller/connection, cycle the chain through every gear and then thoroughly wipe off all excess lube. I have tried so many lubes over the years, and this is the very best!

Saltydog: Over the years I've tried numerous chain lubes and they all seem to fall short of the desired effect. Clean well oiled chain attracts dirt and things go south quickly. Extreme Purple goes on wet and once the carrier oil flashes off what is left behind is a dry extremely effective dry lube that resist dirt attraction. One suggestion I would make is to help mother nature out a bit. If you follow the instructions you are to apply , wipe excess, and let sit over night for best results. The problem I've had is unless the weather is extremely warm the carrier oil never seems to evaporate leaving once again a wet chain prone to dirt attraction. What I do now and works great is this. Clean the chain. Roll into a flat tight circle and place on a piece on scrap ceramic tile. Take an electric heat gun an warm the chain so its nice and warm. Now with the chain heated apply the chain oil. You can see it being sucked into the rollers . If the oil smokes the chain is to hot. Now once lubed put the chain on the bike. Now if correctly done the chain is still a little damp. Take the heat gun and while turning the crank slowly warm the chain as it rotates drying the remaining oil....

Geoffrey Anderson: I am giving this a try. As a long time White Lightning user, I finally got fed up with the waxy build up on my cogs. Chains lasted well, but the annual feel cleaning was a pain.

After buying a new mountain bike, I was reading reviews on MTBR.com and in the maintenance area, there was a long discussion on chain lubes. The conversation around purple extreme was intriguing, and I took a chance.

First, I removed and thoroughly cleaned/degreased the chain. A new chain comes with this assembly lube that makes it glide like butter, and shift super smooth. But that comes with a price, this lube is a dirt magnet, so after a couple of off road rides, the chain has collected a lot of gritty dirt. Off it comes.

Following the directions, about 1/4oz of purple extreme applied, and while the drivetrain is not as smooth with the assembly lube, it is still a crisp shifter.

4 rides in, the chain is fairly "dry" to the touch, but not noisy, the indication of a good application. A few more rides and I will repeat.

I suspect if I rode in the rain a lot, I would breakdown and run a wet application of Finish Line, but for my typical riding, this...

KettleonSonna: I have had this before and it is a great lube for bikes. Simple, clean and all weather. I would definitely recommend!

penthouse dizzle: Having bought this I decided that from that day on I would take care of my chain the way it deserves, and this has really helped. I cleaned it once and apply this lubricant as directed and it has meant and incredibly smooth ride on my Felt Z5.
It's also purple, which is excellent.
