Of all the different lubricant vendors at Interbike, Purple Extreme was the one of the most impressive. After our discussions at their booth, I was anxious to test the samples they had provided.
Upon returning home from Interbike, I read their comments about the lubricant being designed for dual purposes. They mentioned that the U.S. Navy SEALS use the lubricant for corrosion protection. Well, I own an older model Sig Sauer, and sweat and rain during bike patrol has taken its toll on my faithful companion.
So my first test was to check it out. Wow! I couldn’t have been more amazed with how readily the lube wiped away the surface rust collected on my faithful companion. What is even more impressive is that I haven’t had any further surface rust. I haven’t even had to apply another coat to this point. The Purple Extreme certainly lived up to this claim.
Well, the next test was to check it out on the bike. I couldn’t wait to see how the lube would perform during Illinois fall weather. The first test was to go to one of our favorite riding spots where the conditions can wreak havoc on chains and drive train components with all the grit, grime and sloppy mud you can imagine.
I followed their recommendation closely and placed the correct amount of lube on my chain before taking to the trail. The lubricant performed very well under the extreme conditions. It shed away all the mud, grime and grit I could throw at it and allowed continuous shifts throughout the ride. Again, I was very impressed.
Purple Extreme is an extreme pressure additive with no oil, wax, PTFE, silicone or ceramic. All of those elements serve to either get dirty quickly or accelerate wear. They also claim that the lubricant protects from wear up to 400°F down to minus 100°F. This is a little more difficult to test so I guess I’ll take their word for it. It prevents metal-to-metal wear and stops chain wear from the inside out. They also claim it reduces drivetrain noise and will not harden during cold conditions.
My test to this point has proven Purple Extreme is a top shelf lubricant for both my faithful companion and my drivetrain. It can withstand the conditions Illinois and I have to offer it.
