    Nexus 8 IGH on the way out -- What should I replace it with?

    Loved having this hub on my new bike for the past 4 years or so now. Bought the bike with it on and really don't have too much to complain about until a few months ago. Seems to be getting worse by the ride, or just about. Started having problems shifting at first. Thought it was a bad adjustment, but this is something I have always watched pretty close, so adjustment wasn't really the problem. What it does is have a hard time doing is moving down the gears mostly, but sometimes upshifting would sort of "clunk" going into gear. That clunk has now become a mis shift when going from 7th to 8th. It will actually drop back to 6th instead of going to 8th sometimes. I have to stop peddling, or somethings reverse pedal a bit to get it in 8th. No doubt my riding style and my 1000 watt mid drive setup didn't help I suppose. But, 4 years seems good enough, so now I just need to replace it.

    I have given thought to just getting the same thing again, but I have also sort of dreamed about having a gearless hub like the Nuvinci. Really can't spend much more than either of these would cost, so keeping that in mind, what would be good alternates to look at.

    Thanks for any helps.

    I love my Alfine 8. I think they are similar. You can rebuild your IGH. https://www.sheldonbrown.com/nexus8.shtml

      Took a little ride this morning to see how well this Nexus would take the long climbs up to Horsetooth Reservoir. For the most part it worked OK, but it did clunk a number of times upshifting. It was just about 45 miles round trip and took maybe 3 hours or so, with a sandwich break overlooking the Lake for about 20 minutes or so. Gotta fix it though, or one of this times I will have to maybe us a thumb to get home, HA!

        You might want to relube it with the Shimano blue oil dunk method. http://thegoldenwrench.blogspot.com/...eared-hub.html

          Thanks for the replies. I have given thought to rebuilding, but pretty sure alot of stuff will have to be replaced. I have researched the Nuvinci hub and it's just not a tough enough option. May just buy another one of the same. We'll see.

            Spinning Magnet's article on IGH's is informative, he was saying the Shimano 3 speed is a good option for ebikes, said the middle gear is very durable.

              Do you guys think the Nexus is strong enough for a steep climb twice a day, 5 days a week?
              I currently run an 8 speed 34-11 cluster to 46 tooth chain ring.
              I want to convert my mid-fat Cooker but afraid my HD will blow any IGH up in no time doing 6,000 kms per year commuting via a very steep, first gear climb.
              I've seen conversions where they half the gearing/load on the IGH by placing it in the frame and drive back down to the wheel, but not sure if I really need to do that or not.

                My 8-speed nexus has held up very well under high loads but I take it easy on it, especially while shifting.

                I also have a spare, complete Internal Assembly pack sitting on the shelf - they can be had for about $120.

                I plan on "converting" the hub to ATF.

                  I guess I could try one in the wheel and if it blows up then repair and put in the frame.
