My dmr went in the bin. The aluminium dropout part stripped its threads, the bolt isn't long enough. 4:50 hard to explain but the 2 bolts are offset and some hangers are offset so you need to put a washer under the tensioner small bolt or the whole tensioner gets put on an angle. After a year that Eurethane jockey wheel disintegrated. I've got some brand new dmr pedals that have sloppy ass bearings from the factory. They don't even know how to tension cup and cones
Haven't you mounted the CT incorrectly? The jockey wheel pushes the lower chain down and off the freewheel, concentrating the pedal force onto fewer teeth and chain links, causing faster chain wear and sharktoothing. But if the jockey wheel pushes up from below the chain it wraps chain around more freewheel for less wear and more efficient drive.
Yes it's mounted correctly. If I would force the chain up I may only get 1 or 2 tooth more which wouldn't be much of a difference. Think about it even with a regular cassette and derailleur you're grabbing less teeth through all the Cog sizes. Now for the chain wear that could be a double-edged sword I see how you think it could have premature wear. But on the other hand the more the rollers on the Chain comes in contact with a cog could wear it out even faster which they call chain stretch.
@@hardtailrider7172 Hmm....I'm not quite convinced. Note that on a usual derailleur setup the chain runs off the rear cog and upwards to the top derailleur jockey wheel giving the wrap effect described above. After ditching all that for a single speed I was mystified that my chains only lasted 3 months max compared to 5-6 months with derailleur. So i tried a CT and doubled my chain life. The descending chain from the JW grabs the freewheel in front, meshing with more than half of the freewheel teeth. Now compare that with your setup.
@@sidmarx7276 I've been running the same chain on my single-speed for about 4 and 1/2 months with no issues and I'm running an aggressive single-speed. no need to change something that works Flawless for me but I do value your opinion. Trust me I tried to make it to where I didn't have to have a CT I spent a lot of money trying to make that happen but it just couldn't do it.
It is possible to open up the roller to accept 1/8 inch chain - turn it with a lathe if you have one. I used a butane fired soldering iron to melt and push the extra material away. Looks janky but works. They should offer another roller. Pain in the a$$.
40 dollars?? For piece of metal with the plastic wheel 🎡?? I just shortened the chain as much as I need,so it won't fall off the sprocket or a rear cog! Works perfectly! 😊
DMR are awesome, I see what your saying about it's just metal and a plastic wheel. Honestly the customer service is great and all the parts are available to buy if you loose them or break them.
On the back of the packaging it says that it’s better to tension up for better chain engagement, but every video shows them going the other way lol. Read your packaging guys haha

I never knew I needed a chain tensioner on a SS, I’ve been riding one for 50+ years
I got da bomb tensioner the orange plastic cracked not durable, why did you change tensioner ztto? Better than plastic

@@hardtailrider7172 Glad your method works, and i'll try it if my chain starts wearing too near the chainstay.
@@sidmarx7276 I will be putting a video out on Wednesday on the DMR chain tensioner things I had to replace and needed modifying minor stuff.

Please can you tell me the bolt size for the hanger? I have lost mine and need to replace? Thanks

Chain goes on top of the red rubber wheel. Everyone installs these wrong. Even the manufacturer gets it wrong.
No it doesn't. That would literally give zero tension. I tried it on the top first 🤣
Yes it does cuz it pushes the chain more into the cog and spreads the tension out more evenly
With other tensioners, yes but the DMR tensioner was designed the way I installed it
How did u cut ur chain down for the chain tensioner
Good video bro
Great video thanks my friend.
40 dollars??
For piece of metal with the plastic wheel 🎡??

Yes I agree $40 is a lot but but somebody has to make contact😂

40 dollars there now 10 pounds on ebay amazon different bike shops 😮
We re men, we don't need instructions. We prefer to convene over the issue and everyone throw his 2 cents idea about how to do it, lol...
Yes we do 😂
This don’t look my MR5
