Yeah. That’s the crux of it, really. I’ll offer three more points…one that supports this data set but is anecdotal and two that maybe cast a little shade on the muc off data…
First, when I brought up UFO drip on another thread the anecdotal experiences that folks shared seem to (predominately) support what this data show: UFO drip doesn’t have much staying power. So I guess I was a little pre-disposed to accept what Muc Off is trying to conclude about UFO drip. Further supporting the notion that UFO Drip doesn’t have much staying power is Jason’s own advice that you should re-apply every 120 miles. (Note that Muc Off simulated a 112 mile ride!)
Second, remember Jason’s data for chain wear? He just took a campy, dura ace, and sram chain out of the bag, slapped it on the tester, and let it run for several hours. Here is what that data look like:
After Jason went to work for CeramicSpeed he did a similar experiment with stock chains of various manufacture vs same chains UFO prepped (UFO prep is more than just UFO drip…looks like the chains are dusted with PTFE as well). Here is what that data look like:
My main point here is, that’s a lot of data from a lot of chains treated a lot of ways & none of those curves look anything like what Muc Off showed for the UFO drip chain. So, what’s up, Muc Off? Jason seems to have repeatable data. Is your data repeatable, Muc Off?
Final point…notice the conditions under which Muc Off claim to have tested: “a 112 mile ironman stage” simulation completed in 4 hours. ! Ummm…that’s like, record time, right? Why pick such an extreme simulation point? I suspect they picked it because, although it is at the extreme, they can still say it’s possible…but at the same time it sort of maximized chain tension which maximized chain wear for a thinner lube like UFO drip. So the power difference at the end of four hours is well overstated compared to a more mundane power output over that same time period.
But that’s neither here nor there to the main point I took away from this data set…which is that there can be substantial power loss in a drivetrain JUST FROM THE CHAIN. What Andy Starykowicz can perpetrate on a chain in 4 hours I can also do…it just takes me several more hours.
