Ya I might see in time there not very expensive anyway so maybe the next time I’m servicing my bike I might throw a set on and see!They've been around for a long time and were normalised in the nineties by Shimano with their Biopace chain sets. I've used them but can't say I noticed any difference but try them and see if you can.
Great point thereBeen around (see what I did there ) since forever and pushed by various suppliers, including Shimano for a while in the late 80's early 90's. I think on paper, or in theory, they might make sense but in practice this probably amounts to nothing due to the way our non-machine bodies work, which likely negates all the possible advantages in the real world. If they were that effective then they would dominate the chain ring world rather than being the tiny side chapter that they have been for most of cycling history. Don't waste your money.
Indeed,and even if one was able to do so it solves nothing as it simply puts it in phase with the other leg... but as they're intended to be in phase with each leg in turn they're bilaterally symmetrical so you'd be actually returning it to normal.I stopped watching the video at the point where he suggested rotating the ring 180° relative to the 5-arm spider ...
