Re: Brake lever as Chain tensioner or Pizza Cutter
Technocyclist - Very ingenious, but your left chain should not be so slack in the first place. I'm wondering if you have an interesting variant engine or an alignment problem. Can you post or send more pictures of your installation?
JasonH - A proper movement tensioner and retainer is preferred to a contact tensioner. The roller and contact will rob (a small amount of) power.
