O.K so why do they pack that small nylon cracker jack spool in the kits and call it a chain guide or tensioner and it's a channel! with a skateboard wheel , it gives a lot smoother run for the chain without fear of jumping off sprocket! thats what I done and it works for me so thats what really counts!!!

Whatever works for you or me and we can disagree.
I know that the guys using no tensioner don't seem to have a problem with the chain falling off or climbing the sprocket.

I have a skateboard with 4 unused wheels... Anyone is welcome to 3 of them.

I DID have to cut a small groove into the wheel...then I realized the "skin" or "tire" on the wheel came off, leaving a nice flat surface instead of the rounded worn wheel.
Still, yes, it's best to cut a little groove in your roller.

I decided to go with the $5 one from Boy Go Fast. Quality appears to be top notch, I was going to buy from Dax, but it was going to be $20 with shipping. Dax did have the bolt and the nut, but I got that taken care of at the hardware store for .80 cents.

LF, your pixs are a little cryptic.
Is the little wheel from a derailleur, do you use spacers to allow it to roll?
Nice idea, BTW. |

Off a dreailier. First pic shows what attaches to the sprocket and those you toss. Then the hole that remains fits that bolt in the second pic perfectly. It just rolls on the bolt so make sure you get that bolt that has that smooth neck. You can use dry graphite or just chain lube for lubrication. Hit it when you lube your chain. I used both
Both of mine has since broken in half.(I blame the alignment. Those sprockets give you little room for error) I haven't experimented much more afterwards. I'm currently using Dax's roller.
I think if you find a derailier that has metal sprockets it would last. And if you find a sprocket with more teeth it would spin less therefore it should last too.
I loved this mod because the chain rolled SMOOTH. The sprocket touches the rollers only and not the chain body so none of that "bump bump bump" you find in regular rollers. And yes,this sprocket although made for a derailier chain works for the BMX and the China chain like it was meant to be.

I went to the factory the other day and the service person was replacing the idler on one of the robot welder arms .He said he did twice a year,it is made of a white nylon block.I got a section of it which is 3 by 3 x12 foot long.If it works ok i will chop it up into 3x3 and give it to anyone who wants it.HARLEYS DAD | | Thread Tools | | | | Display Modes |  Linear Mode |
