Custom chain tensioner for the Jitsie Varial Race 26"

I made this tensioner to avoid chain slap as the chain would either be too tight or too loose with the snail cams.

Also I can push the rear wheel forward to give me super short chain stays at consistent 374mm (stock is 380mm advertised  - that grows with chain wear)

I mounted the Clean forks with an adapter to go from 1 1/4 to 1.5 headset. The change would change the wheelbase to a longer bike, but measured wheelbase with this new tensioner is just 1081mm (stock is 1085 advertised).

The tensioner mounts to the frame and stays in position even when the wheel is off.
Tension is easily taken care of without the chain mounted and then the chain is wrapped on to the jockey wheel afterwards.
