![]() Weight counts there because it is essentially unsprung weight unless we are running soft, fat tires (most don't). WILL WEIGH both LIME wheels, one without the tire, the other has the Hank tire (about 800 grams, that). So, in summary: I like a straight chainline or.what will be the next step: the cogged belt drives just now coming to marked for internal geared hubs.Īnd WEIGHT: Nuvinci is necessarily heavy, isn't it? Like about ten pounds? ![]() I think/expect that the typical derailleur suffers considerable power wastage due to its running the chain in other than a straight line.Īnd too, for off-road work, that derailleur chain tensioner and the exposed cogs are all dirt and junk grabbers. Q: what is the power transmission efficiency of a good internal geared transmission, v. Not able to do a full search at this time, These geared transmissions must have a higher internal loss than the NuVinci. IF "yes", then the Nuvinci has little to offer over the Nexus Inter Eight, or the very costly Rolloph (spelled wrong), The wheel is based on the old, simple NEXUS basic three speed.Ī Nexus Inter Eight would weight about the same, and can be shifted under full power.īut, as we long ago discussed/asked rhetorically, will such a transmission stand up to the HARD pressure of a fast-spinning Cyclone-type of motor ![]() Need to weigh the assembly, but it is LIGHT, even with the hank in place. HAVE at this moment of writing, a LIME rear wheel (two, one bent and one OEM new, but the Hank is mounted. The power transmission comes, if I recall, from their proprietary drive fluid, which makes the balls and raceways "grip". It is a "geared" transmission, but the "gears" are simply and properly, hard balls. Click to expand.I just bolded in blue a key sticking point against the NuVinci, that I was not aware of before.
