NuVinci n360 conversion

[stoney bones]

Looking for conversion info. I called my local LBS (they are authorized dealer) to get quote on price and parts. They didnt call back so I sent an e-mail to the manufacturer...they didnt respond either. so here i am asking the community.

I have a surly pugsley i would like to put this on. what im curious about is, what all needs to be changed/modified? I have almost decided to pull the trigger but i want to make sure im not going to be running into unforeseen costs.

another question is, can you use a surly MWOD crank with this hub?

Easy conversion. I decided to lace it to a Rolling Darryl. I removed the small and large chain rings. Of course, I removed the front and rear derailers.

Do you have any specific questions?

does the nuvinci come with everything you need to install it? like the chain and rear sprocket? and will this work with a MWOD or is that not advised/necessary?

The NuVinci comes with a 18 tooth cog. You will have to decide if it is the correct size for your riding and front chain ring. Surly cogs fit the NuVinci. You will need to shorten your chain. It should work with the MWOD.

I got mine from bikewagon.com (did an ebay make offer of $300) and it came with rear sprocket, all hardware, cables but no cable houses

I am not familiar with the quirks of the Pugsley, although I would like to be at some point, but here are my observations about fitting a Nuvinci to my Long Haul Trucker:

Chainline: Nuvinci has a fairly wide chain line. I had to keep that in mind when ordering my bottom bracket.

Grip shifter compatibility: Some handlebars won't work, but I think most mountain bike bars would be compatible.

Gearing: Nuvinci has a lowest allowable ratio of the rear cog to the front chainring. 1:1.8, I believe. If my math is right, that makes a front ring of 33 with an 18 tooth cog.

My original plan with my Trucker was to start with traditional gearing and eventually convert it, but when I realized that I'd also be replacing my bottom bracket, and maybe my chain rings, and possibly my handlebars, it suddenly looked more cost efficient to just buy all of those parts with the Nuvinci in mind. It's entirely possible that you could just add the Nuvinci and be ready to roll, but you might want to look at the various components and make sure it will all work properly. Fortunately it sounds like there are some Pugsley/Nuvinci owners who will know what pitfalls, if any, there are.
