*vid* Perfect sprocket alignment every time, how easy is this??

[nidyanazo]

Just thought I'd share this trick that makes the sprocket alignment 100% concentric every time, and takes 2 mins..

With this vid, u may be putting the sprocket adapter peeps out of bizness!

(not!)

Great tip for the MBer on a budget though!

Arent you supossed to have rag joint between the sprocket and spokes?

 

[Al.Fisherman]

1. Rag joint on each side of the spokes..yes
2. I use the tape when able
3. Won't work on coaster brakes.

Wrong, it works fine with coaster brakes.
Our kits include sprocket bolts with low profile heads. Not sure about other kits though..

If you sell a sprocket that the center shaft will fit OVER the dust cover, I want to see it.

That is cool. One of the youtube commenters suggested a piece of zip tie. I wonder if that will stay in there though. I bought a 38 tooth 5 hole sprocket and had to drill my own holes to mount, and sand out the inside hole to fit the hub. Now that 36t offset sprockets are out there, I will be glad for your tip when I need a new sprocket someday.

I'm using 1 donut and have the cog against the spokes. No problems for me.

On another thread, people were using cheap flip-flop track hubs and drilling 4 holes to pull the cogs against the hub. That might work if you don't need a coaster brake.

Great tip Nidyaman! Thanks for the heads up.

How did we all miss that until now? Genius in its simplicity, props to Nidy.

As AL. Fisherman said that trick wont work on coaster brake hubs like those on any of my bikes, either the sprocket or the dust cap would have to be modified before it could even possibly be done I would think.

Peace

That's a good idea,Al ! One of my bike's I had a machinist turn the hole bigger to fit over the dust cap!It would work on any bike.

 

[happycheapskate]

I didn't have such a thing, so I used a half-round file, and an old section of chain on a BMX bike (upside down) I held back on the file inside the cog and spun the crankset of the bike, grinding it down until it fit over my hub flange.

? HElp help, please

Rap tape, cut PVC collier or whatever you can find to take up the slack between the hub and sprocket evenly. Finger tighten bolts, then tighten each one the same amount all the way around 1/4 turn, then test for wobble. Straight edge from engine sprocket to big one, must be touching on all surfaces for proper chain alignment.............Curt
