So I was taking a look at the Rover page earlier and noticed the i8 is no longer there anymore. Not "out of stock" or "discontinued", but completely gone. It is in the online shop, but listed as discontinued.
It appears that NuVinci hubs are the only internal rear hubs offered on any of TT's trikes now. Found that interesting at first, but after some thought it makes complete sense. The Rover was the only model with non-NuVinci hubs for some time now, the Rambler and Traveler lost them ages ago. The i8 had a couple of significantly different hubs that could be used, and the online store didn't let you pick which one you wanted. That's the kind of situation that leads to confused and unhappy customers.
Funny thing is that would have been mitigated a bit with SRAM's recent departure from the internal hub business. That leaves just the Sturmey-Archer. I wonder if costs for the SA were/are going up, bringing it closer to the NuVinci costs? I could see that happening if SA is having the same issue with declining sales as SRAM had. According to the site, the n330 and SA8 setups have similar ranges. I know there have been concerns from people regarding the NuVinci's efficiency, but I don't think I've seen that it's really that much worse than the SA. Given that and how much more robust the NuVinci hub tends to be, I can see why it would be simpler to just drop it.
Curious what other folk's thoughts are.
