NuVinci N360 hub fitting to Sofrider.

I thought I'd start a clean post on my hub installation of NuVinci N360 CVT hub as the original post was about Quest running gear being fitted on Sofrider and then it turned to internally geared hubs.

First of don't believe the dealer/bike shop has any idea of what they're doing most haven't even seen this hub and don't bother to read the instructions.

My case the bike shop did a half-baked job but at least they still helped to sort it out.

First mistake they forgot to check they received the correct hub and fitted the earlier model N170/171, to spite the fact I emailed them to double check N360 model.

Second mistake (part A) when reordering the correct hub they didn't check if the spokes they had fitted in the wrong hub would be ok, the N360 has smaller diameter to the N170/171, another 2 day wait.

Second mistake (part B) when reordering the correct hub again I asked them make sure you have the correct sprocket to suit the new hub, they didn't they again assumed the other one would be ok it wasn't (screw on type, N360 9 spline type) lucky the hub was supplied with 18t sprocket (I needed 16t but it got me going).

Third mistake they supplied the wrong chain (1/8") the hub needed 3/32", and the chain tensioner didn't align with the sprocket again stuck with running extra spacer to get it aligned (I'll revisit this later to get it right) they gave me a 8 speed chain they thought would be ok but it rides up the sprocket at one specific spot on the chain it works but you can't push too hard on the pedals as it starts to jump (hills in low gear where fun almost had to walk!).

Hoping to pick up the 3/32" chain tonight crossing everything that it works, I'm pressed for time with the RAC bike hike is 24/3/13 local charity ride and not ridden much with all these problems.

The Fallbrook (USA) / Southcott Australia agent have supplied the 2012 model with 2010/11 instructions and they have redesigned the shift adaptor setup and it was confusing looking at one thing in the instructions and looking at something different in your hands but worked it out in the end.

But the hub itself, it's heavy but this doesn't bother me for my style of riding, the one thing I found is it helps stabilise the bike, bit like a gyroscope (it is full of oil) gear shifting or sliding is brilliant just a gentle push on the shifter twist grip dials you into the prefect ratio especially on down shifting just push with the inside of your thump and pedalling gets easier a little more resistants on upshifting but still easy.

I tried a full stop in top gear, wound back on the shifter you stop about a quarter of a turn than while gently turning the pedal a half turn whilst twisting the shifter gets you back to low gear, brilliant the main thing I was looking for.

The original thread title ... "Convert the ering & hub from Quest to Sofrider" in the Sofrider section ... http://cruzbike.com/convert-ering-hub-quest-sofrider

Link on installation http://www.parktool.com/blog/calvins-corner/NuVinci-360-Hub+ this is the 2010/11 model the shift adaptor on the axle is different to 2012 model.

Costing around the $600 (Australian) if you can mount the hub yourself (lace it up) and use your own rim it would be cheaper but I wanted to keep the standard setup as spare.

Hope this helps others who are looking for alternatives to derailleurs.

Great post, Greg. Would the

Great post, Greg. Would the NuVinci fit into the Silvio or Vendetta frameset?

Thanks Romagjack,
it would


Thanks Romagjack,

it would most likely fit anything with 135mm drop out and 3/32"chain, the weight puts most people of but if you're not chasing speed and worried about weight it great.

I was after 16t x 34t setup that would get the same low end and one gear short of the original Sofrider had, but with the stuff up above I'm using the supplied (with the hub) 18t with 34t it's lower gearing and short the 2 top gears but still in hi with steady pass 35kph I average (2hour ride) low to mid 20's on average.

Greg

P.S - again waiting for the chain that was supposed to have been ready yesterday ... today maybe who nows, once I have it sorted I'll post the chain type.

With the chain tensionner you

With the chain tensionner you have in place, you could put a double crank on that puppy. Imagine the range you could have with a 38T/22T front crankset... :D

Well finally got the correct

Well finally got the correct chain 3/32" x 116 links, the one that they gave me assuming it would work was 8 speed chain (cut to 106 links) and the link plates are closer together than 3/32", I think it was 7.2mm link pin and the 8 speed was 6.8mm or something like that and I'm guessing the 4-5 links that were riding up the rear sprocket was because of the narrower spacing maybe!.

Leaving the chain full length gives the tension a better looking position (pic below).

After a ride last night and being able to put full pressure on the pedals & with the bit of drive lose in the hub I'm going to need lower ratio than the Sofrider has.

At the moment I'm running ... (the original) 34t x 18t (as supplied with hub), low feels little lower than the Sofrider and the high feels like it's between 5/6th in hi range, I was going to change the chainring to 38t but going to try 36t, the tensioner should take up the difference, I think it may need a bit more tension anyway, from some of the reviews there is a run in period and the hub starts to drive with less loses.

34t x 18t gives you 1.9-6.7
36t x 18t gives you 2.0-7.1
38t x 18t gives you 2.1-7.5
Sofrider is 2.1-> 6th 6.3, 7th 7.3, 8th 8.6

I rarely used 7/8th anyway maybe coasting down hills, and 5/6th I was up & down between them 5th to low 6th to high.

Still not sure what to do with tensioner just enjoying riding again at the moment :)

link to the 2012 model instructions ...

The cable lengths are different and I've emailed Fallbrook (USA) to see if they will send me a new set, they did answer the origianl email which included the undated instructions so I'm hopefull, it does look like it is going full low and full high!.

Tensioner is Shimano CT-S500 for reference.

Hi,
I found the original


Hi,

I found the original Sofrider gearing didn't go nearly low enough (although I liked the high end and even wished it were a bit higher). In my current setup, I've almost halved the gear inches of the bottom gear (from 38T/32T front back to 22T/32T).

Putting a double crankset up front really might be the way to go.

Even if you use a really bad front derailleur, you'll almost never use it. The biggest problem using an IGH and front derailleur is the chain length, but you already have a chain tensioner.

Just plantin' seeds... :)

Hi Greg,
Yes, it clearly


Hi Greg,

Yes, it clearly makes a lot of sense to ride with it a while and decide what you want to do.

And don't worry. Take your time. That double crankset ain't going anywhere.

Cheers,
Charles

Hope that you are still enjoying the Nuvinci N360 as I have just ordered one.

I recently installed the Stumey Archer CS-RF3 with a 9 speed cassette. It makes a good combination but the CS-RF3 disingages when in the high range. Sure would not want to try that one while standing up. Though it was an adjustment problem but that was not to be.

After I get the wheel built, will see how they compare.

After my RAC bike hike on

After my RAC bike hike on Sunday I'm sticking with the 18t x 34t combo I need that low gear ratio and I was using top ratio on some area's of the freeway, went better than I thought staying hi 20's to mid 30's klmph most of the ride, heart rate was highter than I'd like for old falla 160-175 (max for me 168).

Also I'll be shortening the outer cables from the 1200mm I guessed when fitting to about 1000mm I'll post the length when done.

Phil, you'll enjoy the NuVinci hub I'm loving it, if your ride is Sofrider than you should have all the info you need.

NuVinci Hub

Just got the Nuvinci Hub, laced up the wheel and did a 25 mile ride.

After riding one of these, just can't imagine going back to anything else. Easy installation and great engineering. The cables are quick disconnect for easy wheel removal, a real plus. Absolute silence, only hear the tires rolling on the surface. No chain tensioner required. Got a good tight chain fit without a tensioner, another plus.

Floridabike,
Are your using


Floridabike,

Are your using 18tx34t combo and is you're axle center's 450mm if so how many link's is the chain, I'd like to lose the tensioner myself.

Nuvinci Hub Chain

I have an 18t X 28t combo and it works ok for me now. Very windy in Florida this time of year so my top speed is only about 18 mph. I have a 34 that I would like to try and it sounds like that combination is working for you. Unless I mis-counted I have 94 links which came out perfect for the chain tension. I may not be so lucky with the 34t as you always have to add or remove 2 links but I like not having the tensioner. Removing the derailers and all the grears helped compensate for the heavy hub and it sure is quite. Without the tensioner when you kick the peddles around backwards to get in positon to start off it will spin several times if your are not careful.

34t chainring

Greg,

I tried the 34t chainring with the 18t on the hub and I would have to use a chain tensioner. I could get the chain tight but I was uncomfortable as I had to move the axle to far out of the dropouts so I put the 28t back on. Perhaps going to a 19t or 20t on the hub would work. For now I'm just enjoying the ride with the variable drive.

Good to know floridabike,
I


Good to know floridabike,

I wont bother trying that than, I'm happy with 34x18 setup I need the lower ratio more than I need the higher ratio.
