i'd be a little worried about the tensioner going into the spokes after a rock strike, otherwise that's a clever design maybe have a way to attach the other end of it to the chainstay to prevent that?
Hi, I think I am missing something. Why do you need a tensioner again? If it's a single speed without suspension, what limits you to make the chain smaller? Sorry if this seems like a silly question?
Not at all. I should've explained better. Bikes designed to be SS come with horizontal drop outs where the rear axle can be mover front and back to get perfect tension. Geared bikes have an almost vertical slot and the rear wheel is not adjustable. I took out as many full links as I could and still have the chain reach but it was really loose. Each link is 1 inch long so chances are the chain will be either too short or too long by itself. I hope this helps
Yes. An oval CR that’s 32 tooth acts like a 34 tooth when the oval is tall and a 30 tooth 90 degrees later in the pedal stroke. It’s pretty wide range of tension. It you are at perfect tension when tight (chain ring tall) it’ll fall off when loose.
Great job.
Thanks! I appreciate that! 👊
This is a better concept than whats available on the market at the moment, discreet clean lines and it works. Great job.
Thanks! It’s a lot quieter than my old non-clutch-derailleur-tensioner 😁
Good invention. You could sell those.

U need more views and subs ❤️
Thanks! I appreciate that 😊
Why didn't just shorten your chain and use one gear pushing up, the first concept?
Paint it to match the bike and no one would even notice
If you Had the perfect tension for a single speed on a round chainring Would changing it to an oval break the perfect tension?

It's a BIY not a DIY. Bodge It Yourself.
Lol. It works! May not be pretty😁
