    Talked to Manic:-|| Mechanic's shop today and to my dismay found out that the sprocket adapter won't work on my Shimano Nexus 3 Speed Hub. I am disappointed, since I really wanted to use Jim's adapter.

    To that end, does anybody know of any alternatives? I don't want to use the spoke kit that came with the engine.

    Thanks.

    You could try livefastmotors, but not sure. Isn't that hub a large O.D., like 3-4"? I know livefast sells sprocket adapters for either coaster brakes or multi-speed bikes and also can be ground a bit if they need to be resized. But if it's one of those larger hubs, you may have to try and bribe someone to make one.

    I'm confused? Are you just using the Nexus 3 speed hub for pedaling, and not using a jackshaft?
    Also I dont think you would be able to use the kit sprocket adaptor with that large of a hub?

    Get the shifter kit... You'll maximize your hub's abilities... :) I have a Shimano Alfine, with a shifter kit... :)

    I hate to bust your bubble but Jim is doing a sprocket for my Felt MP and it has a nexus three speed. And at first there was a little confusion but after sending photos to him he is now building my sprocket and adapter. You should give him a call first thing Monday because he is doing mine on Tuesday. Hope this helped

    Terry,

    This totally confounds me; the person I talked to told me she they had a nexus 3 speed and she said it would not be possible for Jim to make the adapter & sprocket for it. Unfortunately, I have already ordered the clamshell adapter.

    Wish someone at jim's would have checked with him, before telling me that nothing could be done; I would definitely perferred his adapter & sprocket kit.

    Damn.

    Thanks for the heads up.

    NOt exactly on point but why don't guys change their hubs to a standard one that Jim's adapters work on. Isn't that easier?

    $35 to have your wheel re lace plus the cost of a new hub that would be why. When all you have to do is speak to jim him self problem solved

    Gene,

    Got the clamshell adapter (good product), howver, the adapter fits up to 1.5 inch hub, the MP Felt hub is 2 inches.

    That was going to be my next step if Jim can't make the adapter (the adapter&sprocket are less labor & cost intensive than changing out the hub). Sounds like Terry and Jim have worked out a solution; and I going to place the order Monday for the set.

    Looking forward to installing the adapter & sprocket and taking this baby for a ride.

    Thanks for your advice.

    Yea well not every hub is able to have an adapter made for it so my question is even more basic
    we all ride at speeds not designed for bicycle bearings and hubs and nobody is asking Jim to make a standard hub with tapered roller bearings. For my physical safety and drastic improvement in reliability whats 35 bucks to re-lace a wheel? I would buy a hub would you?


    And if you had a good motor who needs a 3 speed anyway.

    Do motor cycles have tapered bearings,?I haven't taken one of them apart,,,I figured husky heavy duty wheels would have heavy duty bearings.

    Gentlemen,

    Hopefully the problem will be solved. I sent Jim a e-mail tonite, requesting he machine a set for me; since he is already doing one for Terry. I am sure that his shop assistant did not know about the work around for Terry's hub, when we spoke last Thrusday.

    We all can agree that Jim's setup is far superior and economical to relacing & installing a new hub.

    Pre 99 Harleys had tapered roller bearings. In 2000 the design changed to a sealed bearing pressed in the hub. The improvement was it eliminated 10,000 mile wheel bearing cleaning and re packing. The hubs we ride on suck. The ball bearings and the races are pretty crappy. The go fast boys around here aught to be concerned.

    I would rather buy a hub...The nexus 3 speed is a waste if not paired with a shift kit.

    I agree that it is a waste but there is no shift kit available for the 4G T Belt yet so this is only temporary. As soon as one is on the market and I can afford one I am getting a shift kit. 2Dawgs you have to speak to Jim him self or the order will get messed up so you better call Jim ASAP if you want to get the right adapter. Just speaking from experience I emailed Jim with all the info needed but he is swamped with emails and orders so he dose not have the time to read the emails that is why you need to call him.

    And like they said, Jim is swamped so be very patient. I have bugged the crap out of him and I know he is doing his best to get all of his orders caught up but I also realize that his products are well worth the wait. I'm the worlds worst when it comes to patience and Jim probably realizes that now. Simple fact is, you cannot build quality builds without Jims products, end of story.

    Folks,

    Just got off the phone with Karen from Jim's shop and she said that there is a misunderstanding; Jim can not make an adapter for the Shimano Nexus 3 Speed hub.

    So, I am going to buy the Shimano C-110E hub and get my wheel relaced and order Jim's adapter & sprocket setup. Problem adddressed.

    Thanks to everyone for their much needed advice and help.

    Can't wait to put this bike together and ride; even with the setbacks doing this build is a hoot.

    Workman has a wheel with the cb110e hub 11 gauge spokes clincher rim 74.99 plus shipping number 4136a. If that is what your looking at. You have to fish around on there site to find replacement parts list. I have two one on each of my 4 stroke bikes. One has Jims adapter and sprocket.
