After Market Chain Tensioners -- where ??

[Junster]

I agree, the seat post mounted units seem best. At least if it fails it isn't in the spokes. Fortunately for me I bought a half link and discovered that with everything seated in I could now remove a full link. I was able to remove my tensioner completely.

thanks for all of your help so far motor bike riders

not sure if the one or ones that attach to current tensioner would be good to use ??
reason -- many times that is the part that goes wrong -- letting it twist on frame

ride that THING on a 45

I just got back from about 20 miles with no chain tensioner. What a difference. Much less vibration and alot smoother feel. I did the "t-shirt" shim behind the rear motor mount to adjust the chain. This is a way better ride now.

Large Fillipino made a good thread on a sprocket chain tensioner, same as on millions of current production bikes. Why reinvent the wheel? It 's as quiet as a rear derailler

 

[Mountainman]

yes -- the one made by Large Man is nice -- for sure

not trying to reinvent the wheel here
just want to give riders a place to come to so as to get many good ideas regarding idler wheels

when I worked with machinery for years
saw many many different types of idler wheels - gears
and most were super heavy duty -- almost never threw a chain or belt

this is what is needed for motor bike riders

be nice if those so called kits came with someTHING better !!!

ride that thing sideways

the plastic gear will wear pretty quickly (a lot more force is applied to it)
an old school metal gear would be perfect

can you email me...

very well put, mountainman. i'm making this my priority because my new build is fast enough to scare most people riding it. the tensioner pulley is the weak link on multi-speed bikes with an offset rear wheel. if either the tensioner pulley , smaller teeth sprocket, or rear wheel moves slightly out of alignment to the engine sprocket, the rider is going to get seriously hurt when you're gunning down the road at 30+ mph. i spent over 3 hours reading every post about tensioner pulleys and have collected pictures and such on various home made ones. if anyone needs them i can email them to you. sorry but i neglected to document the names of the posters but i will try and go back and add them to my compilation because they really deserve proper credit.

i have gone through 2 tensioners in pretty much a week!! or just where to get a replacement pulley!! its the pulley's bolts which keep breaking on me as i'm trying to find an adequate adjustment for them!

Tensioner

her is what i made. sporkets are from a derailer they are plastic. top one is a guide and bottom is a tensioner. put them under the chain to help hold them then the chain droops from gravity. works good so far. it is louder than with no chain but seems much safer...

That is brilliant AdamT. This is the best one I have seen so far.

my eyes are trying to see this Adam

kind of hard to see Adam
do you have two idler sprokets on there ??
if so
the one on top maybe -- should be removed ??
they are only meant to be used on the slack side of chain ((return side))

have fun as we ride those things
