Alternatives to Jim's Sprocket Adapter

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.
