Many here are probably aware of my ongoing love hate affair with friction drives. My latest design has been tested over 5000km of commuting and has been been documented on this thread https://endless-sphere.com/forums/viewtopic.php?f=6&t=74269
After discussions with US interests, I have continued to refine this design, reducing the parts count and increasing its strength and reliability. My under bottom bracket design has been copied on a number of occasions and even commercialised under the pretences that it is their own unique design. Having always been open with my designs I suppose there is not much I can do about that.
Although this latest design looks to be simplicity personified, it is the culmination of many years of development, trial and error, and real world testing. It has its limitations as with all friction drives but on the right bike, has proven to be an amazing performer.
Precision laser cut from 304 stainless and assembled completely with stainless steel fasteners, this drive is built to last. The design allows for left or right bottom bracket mounting and has a unique end stop adjustment system which makes setup and adjustment very quick and easy. with the drive being so well hidden, powder coating is an unnecessary expense and as such an elegant brushed Stainless Steel finish has been opted for. The low parts count and economical manufacture of parts means the drive can be brought to market at the right price point.
Its not for sale quite yet but watch this space. Here are a few teaser shots.
