Cleaning specialists Muc-Off have launched C4 Wax, a chain lube that has been developed with Team Sky. Muc-Off claim the lube can “produce savings of over 7 watts for a 60-minute time trial.” Their words, not ours.
Team Sky, who have been heavily involved in the development and testing of the new chain lube, first used it in this year’s Tour de France time trial. We know of course that Team Sky’s philosophy is all about marginal gains and even the slight difference a chain lube might potentially offer is something they'll take seriously.
“In a discipline where seconds can be the difference between 1st and 10th place, it is a marginal gain that can help steer a rider to victory,” says Muc-Off.
To help them test and develop the new C4 Wax, Muc-Off built a ‘Chain Lube Efficiency Dynamometer’ that allowed them to thoroughly test the “efficiency and performance durability” of the new product, before it was fit to be testing in the real-world with Team Sky. The video above shows this contraption being used.
“This [Dynamometer] allows the Muc-Off R&D team to hand pick the most efficient chains before treating them with the C4 Wax. After they are treated, the chains can be tested again and graded accordingly. This process allows Team Sky to give their G.C rider the most efficient chain and the other members of the team will use the chains that fit their role in the team,” adds Muc-Off.
Unfortuaently Muc-Off have no plans to make this C4 Wax available to the public, they are however developing a new lubricant based on C4 that will be available in the near future, and be easier to use than the heated wax system of C4.
