Description
This is my BBSHD motor Dual Sprocket Chainguide & Tensioner meant for single speed ebikes. It is designed to work on engine positions from my hardtail to my DH bikes and secures to the back of the motor (using the available threaded holes). It has an adjustable Chainstop keeping the chain secured on at the top of the chainring. It is 3d printed out of PETG for its temperature, mildly flexible, and abrasion characteristics. Stiffer materials I tested did not perform as well. It has a steel cage for the sprockets and a strong spring to keep tension. It has up to 180 degrees of motion under tension so it can handle big travel bikes. The tensioner moved upfront helps reduce the rear unsprung weight and improve the traction and handling characteristics of your ride. Partnered with a rear Fixed Sprocket (bearinged) guide to lock the chain at the bottom of the rear cog. This also resolved issue with all these old bikes I love having hard to find, bent derailleur hangars throwing things off.
I currently have designs ready for 32t & 36t chainrings.
