Anyone use an Ochain thingy?
- Thread starter ChrisRobin
- Start date
Back when those were still around our group of riders all got skooled on every climb on an 15mile XC ride by an invited along mate of a mate. He brought the wrong bike thinking we'd be riding DH and just ride it regardless. It weighed 52lb and had a 42t ring and a 11-25 cassette.
Humbling day.
figures....
maybe y'all will believe a lot of what some of us have been saying when steve says it
clutch derailleur discussion starts around 11:50
he also goes through the pk difference in rolling vs static rear wheel at the beginning
also addresses braking which westy's demo doesn't account for
With all of the above amounting to an expensive product that may kinda sorta partially address an extremely low percentage of scenarios that occur in reality, especially if you know how to use your brakes, and will make climbing up or pedaling over super rough stuff compromised in more common scenarios

Why let it bother you so much when you're not dumb/naive enough to fall for it yourself?
Substitute "fast person" for "well known accomplished professional partaker" and that's the exact same strategy every "sport" sells it's gear to amateurs and hobbyist by
Several reasons. I don't like when people misrepresent reality to sell useless shit. To me rolling around in the woods on one of mankind's most elegant and simple machines is a way to get away from all that crap. I don't like that this entire industry preys on people's lack of knowledge and even gullibility, now simply refreshed with every new generation who doesn't know this is how bikes are primarily sold these days when most of them all work pretty damn well. A reminder that I'm not even the one who came up with all the lizard jokes to poke fun at this exact phenomenon.....
For all the self congratulatory 'human powered' and environmentally sound perceptions of what riding a bicycle is, this is one of the most wasteful industries I've ever participated in. I'd say it's actually THE most. Unneeded widgets are a huge part of that, along with needlessly changing standards every two years just to get people to buy new shit they don't need.
Plus I know and respect buckow. So when he says I just need to ride a dh bike on world cup dh tracks to understand the appeal of the next widget, he should know better than to fall into that trap. I'd much rather hear HIS opinions on something than "check out that racer on it, it obviously works because you know.....reasons"

I get that it saddens you when friends fall for it but honestly don't get why the bike industry doing it annoys you so much when the world is litterally full of lies to sell shit. but worse still lies to take from the most in need.

Don't think I don't rail on that shit too.
A lot of what I'd consider the bad bits of the mtb industry I used to be able to ignore and escape. Of the last handful of frames I've bought over the last 10 years each and every one of them I had to get a new wheel or wheels for, a new BB, some stupid crank shit, none of it because of any functional improvement in design (some of it backwards even), but rather because some asshole in an office decided this was a way to get an appreciable part of the bike population to buy something new they wouldn't otherwise 'need'. That combined with the imba brain takeover of trail construction here neutering anything that was legit, fun, rowdy riding and I just got squeezed out of something I used to genuinely love, but just kept getting more and more annoyed with. With increasing popularity, this sport just got a lot more predatory on it's users. Anyway, I'm mostly done with it. Y'all can have it. With the demise of GG, there's not a single company out there I ever want to give money to again.

In that case just keep hold of an old bike you know works well from your favourite era. Take it out from time to time and enjoy riding for what it is. component wise there's still nothing you can't get hold of to keep older bikes running (usually a lot cheaper). Surely it's not that difficult to ignore fashion?
You know fine I don't really buy into new new shiny shiny at all... and when out riding I've always prefered seeing pinners on old bikes than all the gear crowd chatting shit about the latest/next gimmick. So long as they're happy and I'm happy nothing else really matters.

that's the plan
doesn't help the local mtb club keeps fucking up trails however....
I can't slave over a mcleod for hours to build what I want to ride any more.
I'm enjoying running over endurobros all with the same moustache and pit vipers, as well as the sierra club douches while riding my dirbike too much at the moment.

Damn dude. They/we can keep trying, but no amount of lizardry and trail fuckery will keep me off bikes.
You know I'm a picky motherfucker
You remember that trail I was building that y'all came out to and hung out for a bit? I got a few days help from two other people but I built that whole thing myself. I get yelled at by people on mtbs when I ride my dirtbike up it, explaining to me who built that trail and why it was built for them.

Nice. It's one thing to be ignorant as to what it takes to build a trail (like most people out there), quite another to claim it as someone else's work. Next level douchebaggery right there.
Anyway, stay gold Ponywooboy, stay gold.

This year they do not run those anymore.....and you know what happened to all their team riders? Just sayin.....

It used to be, Ponywooboy.I'm not sure my blind optimism is what I'm best known for
It used to be.
I did not dive enough in the ochain thing to build an opinion around it, but I swear that when I switched my 30t chainring for a 28t, while replacing the 18t by a 36t ratchet in my DT 350, I did not notice any pedal kickback anymore. It was not super noticeable, but I thought it would be the opposite. If anyone knows why and cares to explain, I'm curious to why. Bike is a Meta AM '20.
Roger that Brother. He was big here IMHO, but not that Frame. I never seen one. My fault on the 10 comment,did not see it? That Frame to me,is one of the Heviest Looking frames of All time.
Another wonderful memory I have of Shandro is a video he did way back. I cannot remember the Name? However,the scene in the video is this: Andrew gets up early in the am and walks out to the porch to look at the mountain. Does not look good,grey with black in the clouds. Phone in hand,Wade says good morning to him. Wana go for a ride? My next memory is of them starting the ride with my favorite SRV in the backround. Has tobe top 5 for Avy.
Avy
How do you know that the bike is well designed? Use the o-chain money to buy a little more expensive bike?
yes the mondraker discussion was a few pages ago
I won't tell you about Q-Z chain I've already built then.
I did that so that you run out of letters and have nothing left to sell.
well you could run two p-chains with the o-chain and get the o-p-p chain effect. YOU DOWN WITH OPP?
and i believe that the proper way to carry drinks, as tested by me during a local urban goon ride years ago is the whiskey bottle in the cage and the imperial stoutlebak on your back...
in fact, my current avatar pic was taken at the end of that day. look how much winning is occurring!
The next step is to just get rid of the chain part and have an O-Ring drivetrain.
Ran the o-chain bike (Speshy Enduro) at Purgatory and some rough surrounding trails this weekend.
Purg is blown all to hell right now and whatever it does the o-chain does something good in the high speed chunky stuff. The bike feels smooth and fast there. Very confidence inspiring.
Here is some data acquisition o-chain testing (not mine) as well for the non-believers.
Slightly higher tech than bouncing the old XC bike on a trainer.

Downamics Racing Performance on Instagram: "Crank accelerations recorded on a run with no @ochaincomponents (first video) then another run with the @ochaincomponents installed (second video). Synchronized data shows the vertical G-forces measured at the end of the crank and what you'll see is sections of track with accelerations up to ~6-7G's on the run with no O-Chain are significantly less on the run with the O-Chain as well as increased stability at the feet. Low speed damping for the pedals. . . . . . #mtb #dh #mountainbiking #mountainbike #downhill #ochaincomponents #testing #data #datadrivendescents #dataanalysis"

Downamics Racing Performance on Instagram: "Some of the results from the testing I've been doing on the @ochaincomponents I did three runs with the O-Chain on the bike and another three runs without it on the same track, in the same conditions and with no other changes to the bike. The headlines are: - O-Chain didn't have a discernable effect on the suspension damping, which is a good thing in my opinion. There are marginal differences but these are in the regions of 2-3% (which is more likely due to other variables such as speed and slight differences in line choice). - On lower velocity crank accelerations, the O-Chain reduced the impact of these, especially when you look at ±15° of crank movement either side of horizontal. This is great because it keeps the pedals isolated from the most common types of bump forces that cause pedal kickback. There was a 14% cumulative reduction in time exposed to accelerations ranging from 0 to 5G's. - Higher vertical crank accelerations weren't influenced or reduced by O-Chain, but I was expecting this to be the case as it quickly moves outside of the O-Chains operational window and the time exposed to these kind of accelerations (7-16G's) was 0.4 seconds for the entire run, as opposed to ~26 seconds of accelerations ranging from 0 to 6G's. Think of the O-Chain as low speed damping for pedal kickback. It's important to remember that this case study is specific to the bike I tested on (modified Commencal Supreme V4), with the same gear ratio on every run (34t chain ring and 17t (or 4th gear)) with a low engagement DT Swiss 240 hub and coil shock. All these factors will have an influence on the result. Also, this isn't an exhaustive or comprehensive breakdown of the testing I've done as there's more to learn but this is where I'm at currently. . . . . . #ochain #datadrivendescents #dataanalytics #dataanalysis #dh #downhill #mtb #mountainbike #pedalkickback"

Anything unusual about that particular bike?
Congratulations. They've damped chain slap. Which on a 20 ft chain, I'm sure gets to be pretty significant.
