Review on DMR Chain Tensioner Stainless Steel by Cris Drew

No assembly instructions. I fitted it incorrectly the first time and over time (while riding of course) I realized that with the chain constantly loosening something was wrong, but I can't understand what was. So I had to do a quick internet search to solve this problem. Everything was ready and installed correctly, I had to attach an aluminum angle arm from the MDR to the bike frame to strengthen the mechanism and avoid the loosening problems I experienced a few times. even with a properly installed mechanism. This is due to my riding style (hard cross country here in the high hills of Los Andes de Venezuela) and the drive ratio used (22 to 14 to be able to ride uphill in very rough terrain). It may not be necessary, but I opted for a leverage solution to avoid over-tightening the system's iron bolts to the aluminum brackets. In any case, be prepared to do some mechanical repairs from time to time (when the chain wears out), re-tighten the cranks and pedal brake more often, and forego a "quick fix for a flat tire". I think the system will work perfectly. with a ratio of disks from 32 to 17-21. In any case a good and reliable solution to get a single speed experience. Sorry for my english.
