As a 200 pounder, I am classified as a “seated climber”. In other words, it is much more effecient for me to remain seated when climbing than it is to lug my giant arse out of the saddle to grunt my way up the hill…thus the need for some sort of rear suspension.
Ever since I started single speeding, I’ve been using some sort of rear suspension. My first SS foray was on a K2 Razorback, but I couldn’t get the tensioner/cog combo to work for me. I gave it up quickly after a banged knee and a shot to the nuts from the top tube.
On my current hardtail SS, I use the Moxey Suspension Seatpost. Since these posts don’t exist anymore and parts are unavailable, I don’t like to spend lots of time on it…..especially since the Cane Creek sucks crack.
So I’ve begun my second foray into full suspension singledom. With the generosity of Renny at YESS Labs, I now have a full suspension specific chain tensioner. My second ride with it was the Horny Toad NMORS XC race which I crushed on a 32×17. I had some skipping, but I’m pretty sure it was related to the slightly worn aluminum cog with a new chain. I put on a steel 21 t for the weekend and rode over 6 hours with it. I got no skipping or popping! I also don’t have a front chain guide or tensioner other than the cateye chain watcher….which I probably don’t need as I’ve yet to throw the chain on it. I did drop it during a night ride when rolling a 20 t after the Horny Toad, but I think my chain alignment was off as I was popping excessively in the rear.
Setup is tedious with this device as there are 5 points of adjustment. The use of almost every allen size on your multi-tool is required. Once set up correctly, it works really well. I really like the fact that it works! I never had luck with the rear deraileur as a tensioner and the stupid little “singulators” don’t work with the lower swingarm being in the way. I have to use those as a push down tensioner which does not allow for any chain wrap on the cog.
The YESS ETR-D has a fixed upper bushing/roller/pulley/thingy that allows for maximum chain wrap. The lower pulley is a standard pulley that is spring loaded with a cantilever brake spring. I found that running the spring with max tension and as little chain as possible provides the best performance. There is a bunch of leeway for adjustment in pulley position and spring tension, so set up may take a bit of time.
You’ve already heard me complain about set up a couple of times. There are some other things that may bug you that kind of bug me. I don’t think this device was originally designed for epic SS rides. I think it was designed for dirt jumpers or park riders who want to forgo gears on their FS bikes. I say this because the thing is noisy. The upper pulley/bushing/roller/thingy is quite loud on the chain. I don’t think it really adds that much friction to the system, but it is definitely more than a sram XO with ceramic bushings. Not being able to remove the wheel hasn’t been a big issue as I’ve yet to flat while using it. But if I were to flat at hour 5 of an 8 hour adventure, it may cause some problems if I space off and lose a skewer spring or nut. I also have only done wheel changes on the work stand, so doing it off the stand may pose some additional challenges. These are the only gripes I have. I think that Renny has something pretty good here and if demand dictates it, some minor changes may help create a product that would work even better for us long haul SS’ers.
This thing will get a ton of use this fall and winter and I’ll be keeping Renny updated. If you are using one for SS XC use, let me and Renny know how it is treating you. Maybe we can help develop one that is quiet and allows for easier wheel changes.
This year’s Horny Toad was as rowdy as years past as a really bad band decided to take the stage at 11 pm and played till 2. They got worse as the night wore on and their bass player dropped out somewhere around midnight.
Here’s some shots from the chainless DH from which I have retired.
It’s tough on our dog here in the desert. She’s a swimmer! She loves hitting the creeks and ponds on our summer travels. At the end of every summer the Mary Tobin Pool, not far from our house, opens up to dogs! $2 and your dog can swim in the pool. We took Luna down on Saturday for well over an hour of hard swimming. Once she figured out the ramp, it was non-stop fetch time. They even had a swim race. Luna raced 5 other dogs. It went a full 25 yards, but Luna couldn’t figure out how to jump in. While all the other dogs were swimming away, I finally threw her in. It took her a second to figure out what was going on, but with Jen on the other side calling her, she straightened out and started throwing a wake. She caught all but 2 dogs to finish 3rd. She got a cool little trophy and stuck around for the podium with the winner Peaches…who was owned by one of the skankiest lookin’ chics I’ve seen in a long time.
Today we went back down, but only had 10 minutes left to swim. She showed every dog there how it’s done. Jen threw the log out to the middle of the pool almost every time and she hauled butt fetching it back. She continued to buffalo her way around on the ramp with little regard for other users. We can’t wait for next year.
We’ve been getting some much needed rain. It’s getting the critters out. Jen and I saw a nice size diamond back cruising across Sotol, but I didn’t have my camera. It didn’t make a sound. Nice set of rattles too.
I went out by myself last monday and saw this fat horny toad.
Then I saw this creeper. I saw some more not long after, but I wanted to keep the pace on.
Have fun out there and respect the wildlife.
Gonna have to figure out how to configure the camper for a crib.
