Friction Facts, a company acquired by CeramicSpeed in 2016, ran a very interesting test to determine the efficiency of a Gates belt drivetrain in comparison to a typical chain drivetrain. It turned out that, depending on the power output, .
Back in November, BikeRadar reported on a drivetrain efficiency study by Friction Facts, and our relationship with the component tester continues to bear fruit, with this installment.Friction Facts has developed test equipment and protocols to evaluate friction losses in bearings, chains, jockey wheels and lubricants. The Boulder, Colorado-based lab will continue to offer its. Friction Facts had this test jig built to find out - and yes, they do, albeit very slightly. .

CeramicSpeed's 11T pulley test has Dura Ace 11T at 0.159w total and CeramicSpeed 11T at 0.033w total -- a difference of 0.126w.. The most recent Friction Facts oversized pulleys report (page 6), however, has Dura Ace (with Dura Ace cage) at 3.80w and CeramicSpeed 11T (also with Dura Ace cage) at 2.96w, both on the heavy cage setting. A difference of 0.84w, or 6.7x .This test was unique from the other chain tests performed by Friction Facts. In previous chain tests, the Full Tension Tester was typically set at a span tension simulating 250 watts rider Two simple experimental facts characterize the friction of sliding solids. First, the amount of friction is nearly independent of the area of contact. If a brick is pulled along a table, the frictional force is the same whether the brick is lying flat or standing on end. Second, friction is proportional to the load or weight that presses the .Much of the friction is actually due to attractive forces between molecules making up the two objects, so that even perfectly smooth surfaces are not friction-free. (In fact, perfectly smooth, clean surfaces of similar materials would adhere, forming a bond called a “cold weld.”)
The last friction testing of chains was done by Friction Facts back in 2013 and I believe was done with factory grease still on which heavily impacted results – so obtaining outright friction results will be great indeed to match with longevity results from ZFC testing. Fingers crossed.CeramicSpeed acquires Friction Facts - BikeRadar
Friction Facts, a company acquired by CeramicSpeed in 2016, ran a very interesting test to determine the efficiency of a Gates belt drivetrain in comparison to a typical chain drivetrain. It turned out that, depending on the power output, both belts AND chains can be more efficient. Huh??? (You can see the full test report HERE) Preload Tension Friction Facts is a lab based in Boulder, Colorado, that specializes in quantitative mechanical friction testing of bicycle drivetrain components. While some may dismiss some of the lab’s findings as trivial, racers who seek every last possible advantage might be surprised at where they might find some extra speed — and how much is actually . 1.1 This guide covers information to assist in the selection of a method for measuring the frictional properties of materials. Requirements for minimum data and a format for presenting these data are suggested. The use of the suggested reporting form will increase the long-term usefulness of the test results within a given laboratory and will facilitate the .Bigger pulleys are more efficient, reducing friction and improving performance in cycling.
Zero Friction Cycling uses the most robust testing – both in house controlled test and field testing as well as from the most accurate test labs around the world, to determine very select best in class products. ZFC selects only the those whom have brought a great product to market, not those who have simply brought great marketing to the . Test results show a 1.2-watt efficiency difference in pedals.

As the Friction Facts lab test was conducted at a power output that’s higher than that of the average cyclist, let’s run a simulation at a more suitable power output of 150 watts. Drivetrain friction reduces linearly according to data shown in the belt drive test. This has allowed me to estimate a 31% reduction in friction for each chain . Ce test n'a pas à vocation à tester la durabilité des roulements, nous mettrons de ce côté ce paramètre.
