|Post-Odin's: DuMonde Tech|
First I wanted to give you all a look at how my DuMonde Tech lubed chain did at Odin's Revenge a couple of weeks back and tell you my thoughts on the performance so far.
It is going to be hard to impart to you readers just how severe the dust was at Odin's this year. Essentially, it was the polar opposite of what I put this very same drivetrain through at the Dirty Kanza, where it was wet and muddy. Odin's had this powdery, fine silt that was getting dumped all over the drivetrain at the bottom of every hill and on every dirt road I rode on during my time in the event. Probably around 30 plus miles of dirt roads alone. Each time I rode through a valley or a dirt road, the chain was getting bathed in this fine dust.
The result was that I have dirt stuck to every non-contact point on the chain, but where the parts meet and mesh, the chain is completely clean. DuMonde Tech recommends that you not reapply lube until you hear the chain. So, post-Odin's I kept riding, and only just the other day did I detect any chain noise. I'll probably back pedal the chain through a rag to knock the dust off first, then re-lube it. While it doesn't match up with DuMonde Tech's mileage claims, I don't think dumping bucket loads of dirt on the chain while riding was accounted for either. Same with the DK200 mess. Both very extreme circumstances, and I am going to take that into account here when comparing and contrasting with the other lubes in this test.
|Rock & Roll Gold so far....|
The next contender I wanted to show you is the Rock & Roll Gold lube which is on the Standard Rando right now. I applied this lube per label instructions and have about 25 miles of commuting and about 16 miles of crushed rock road with an additional 10 road miles on the chain.
The Rock & Roll has been keeping the chain looking really great until the 16 miles of gravel happened. That dirtied up the chain to what you see here so far. The roads were overlaid with fresh gravel for about half of those 16 miles, and the rest was typical Iowa gravel, so nothing really extreme here.
What I am seeing here is concerning me a bit, but I will reserve final judgement until I can pile on more gravel miles on this chain/lube set up. So far the shifting performance has been okay, but the drivetrain is noisy with this lube in as far as shifts and just running down the road is concerned. Not at all squeaky, just mechanical sounding, if that makes any sense. I hope to get a gravel ride on this bike this week to get me into the same territory in terms of mileage that I had with the T-9 before I punted that lube out from the test. I'll have an update along with the Pro Gold very soon.
