G'day all
As some of you may know, i have a SickBikeParts Jackshaft Shifter Kit installed on my bike to great success - to be truthful, a single speed drive system is a waste of time.
One thing that has been bugging me though, since installing the kit, is the issue of maintaining an appropriate level of chain tension from the output shaft to the chainwheels as it stretches.
For the most part, it's not a problem, especially for those using their bike as recreational enjoyment.
I on the other hand use my bike as a sole means of transport and need reliability and functionality to be as good as it can be; travelling up to 100 kilometers per day (approx 60 miles) witrh trailer attached necessitates absolute reliabilty and ease of use.
Messing around with adjusting the chain tension is something i "need" to eliminate, something you don't want to or have to think about, especially when travelling daily long distance commutes.
Necessity is the mother of all invention and in so saying, i'm posting my solution (so far proven to be reliable) for an automatic chain tension system, that "works".
A picture tells a thousand words.
Cheers Fabian
