    NuVinci Pugs

    Laced a NuVinci on a Rolling Daryl with a Nate for my Pugs. The NuVinci is really cool. No shifting noise or sensation. Its more like a volume control. Takes a little getting use to since I am use to Alfine 11's on my Jones'. Not too sure which one I like better yet. Need more ride time to compare.

    I'm interested in what you like better also. I'm debating getting one for my pugs. I just don't know which one and this would help. Let us know what you decide.

    Looks sweet.

    I saw some reviews on them and looks like the N360's are a clear winner.

    Though I would like your input using it on a fatbike, especially riding in the cold, through water, mud, etc.

    I had one on my first Pugs and liked it, save for the narrow gear range. I'm interested to hear what you think of it in terms of climbing.

    it may have been a fluke, but mine blew up after a very limited number of miles on my fat bike. began intermittently freewheeling forward, and then wouldn't engage at all. conditions did not change at room temperature and there were bits rattling around inside, so it wasn't just the cold. the company was accommodating and friendly with the warranty claim process, but I probably would never put one on a snow bike again out of fear of being stranded.

    Was this the N360, or the first generation model? I recall a few folks had slipping issues with the 1st gen.

    Gnarly Traction

    The Nate on a Rolling Darryl at 14 psi has awesome traction. Riding the lake shore has never been so easy. I was able to go places where in previous rides the Endomorph and Larry lost traction. The NuVinci is working great.

    Note: The picture was taken before the engagement with mud.

    How much do you weigh? That's pretty high IMHO. Closer to 8-10 will yield far more traction happiness for the average 175ish rider....

    I'm about to build the same rear wheel for my pugs and was trying to do a quick sanity check (planning on ordering the parts now). Did you end up with some very short spoke lengths? I think my calculator ended up with around 231mm spokes. Not finding a lot of options at that lengths.

    Just kinda curious how you built yours up.

    Keep us updated as I'm interested in how it turns out for you. I figure it's a fun experiment (we're severely lacking snow here at the moment).

    Running a Rolling Darryl. Spoke length I calculated and used is 231mm. 2X pattern. A 3X put too much of an angle on the nipple (no pun intended). I have a LBS that has a spoke cutter and is excellent to work with. So far the NuVinci is fantastic. There is a break-in period of about 100 miles. The shifting is like a volume control. Everyone that rides it just smiles. You are more than welcome to take it for a spin if you find yourself in my neck of the woods.

    It would be awesome if nuvinci made a hub for mukluks.

    It would be great if they did made something for the other fatbikes..

    cool. what ratio are you running? i'm thinking of trying around 32-20 to start, but really need a little lower (32-22) to be able to make it up some steeper climbs. that falls under their 1:1.8 ratio, but from what i'm reading it doesn't sound like it blows up like an alfine 11 might.

    A new Nuvinci Pugsley is born!

    NuVinci Pugs-image.jpgNuVinci Pugs-image.jpgNuVinci Pugs-image.jpg
    Finally got around to lacing my eBay sourced N360 onto a new RollingDarryl rim. Build was pretty straight forward and I am enjoying the hub! Running a 36/22 gear combo, giving me most of the middle range of my previous 2x11 set-up minus what feels like the top two high gears and the lowest granny gear. Still sufficient for my needs, I think. A bit squishy feeling at first going from the very efficient derailleur system, but I feel I have gotten used to it pretty fast and don't feel much slower on my regular rides. Maybe not the first choice for racing, though!

    Happy to answer any questions and share ideas about this hub and its application to fat bikes.

    Would be curious to hear long term report. I tried to like my N360, really tried - had it on my KM and on Moonie, sold it after couple of months. In higher gears it was OK (although huge weight penalty was quite pronounced, my KM wheel (laced to Dyad rim) was at least 10-11 lbs by itself). But in lower gears it felt like mashing through soup
    (Moonlander, Krampus, 1x1, Pacer, X-Check,Big Block, Space Horse, Nature Boy Disc, Kona Unit, Bertin, Falcon, Awol) +.

    There's a new model with slightly less range - 330%.

    Don't know if this means it is lighter though. It sounds as if they are concentrating their efforts on the ebike market though.

    That's kinda the vibe I got.

    Slightly absent low end - smooth power conversion / no jolt action. Makes sense from a business standpoint.

    I could see one heck of a fancy utility bike in my future.

    I reckon they would be perfect for mid mounting. They could gear it up to spin it faster, and then reduce it from there. That would eliminate the increased drag from underdrive in high torque situations, so quite likely it could be made much lighter.

    So a week into it I am really enjoying the Nuvinci N360 on the Pugsley. Most of my rides have been flowy single track with some short steep climbs, as well as creek beds with lots of rock gardens, logs and deep water crossings. This thing does exactly what I need it to do, which is to shift on a dime and take a beating. And it gives me lots of OPTIONS! I am always in the exact gear ratio I want - no more getting stuck after hitting a sudden climb while in the wrong gear - and no worries about submerging my rear hub in dirty water or smashing my derailleur on a rock or log.

    I have felt some of the squishiness referred to previously, especially in the lower range. In my mind, I imagine it as the transmission fluid hardening under pressure and as the distance between the drive spheres and ring increases this process takes an instant longer. I have gotten used to this, and noticed that I only feel it on the initial application of force to the pedals. If I keep a steady pressure as I pedal it does not feel squishy, which I think engrains good pedal technique and is def not a deal breaker.

    As I said before, this hub would probably not be a good choice for racing, but for a bomb proof and maintenance free system you can beat the crap out of and have a ton of fun with, I think this technology has alot to offer!

    I also have an Alfine 8 on a 29er which is great fun to ride and is definitely more efficient, but has less range and only 8 options...

    My Nuvinci didn't last long in my Origin8 Crawler, about 7 months. Original wheel build with stock 32x18 gearing. It spent most of it's time in low range, singletrack or snow. Pawls were destroyed.

    My other wheelset is 47mm rim, I never had an issue with the pawls in that Nuvinci, I changed up the gearing a bit with that. I had to keep re-adjusting the shift cables because of where the axle would sit in the dropouts after gearing changes. That got old quick.

    I gave up on it, I couldn't make it do what I wanted/needed. So I converted the Crawler to a dinglespeed and love this setup!

    I think if you don't change gearing often, and keep it's use to road/gravel riding, not low range mashing, it should be good.

    TrailCrawler you may have been unfortunate recipient of one of the early hub batches that experienced insufficient hardening of the freewheel. They resolved the issue quickly, if memory serves.

    I'd return to using the hub, squishiness and all -- if I could get a real, ultra low granny gear without having to violate manufacturer spec. The shifting action was delightful... but when I bonk, I bonk hard and need that granny gear.

    When you say the pawls were destroyed, you mean of the freewheel? I had an issue with mine where the freewheel wasn't destroyed, but the clip holding the mechanism in place came loose, causing the freewheel to disengage. The hub was shifting just fine, but no power was being transferred through the hub. Tech support said that had been an issue that some pre 2012 hubs had had, but they'd addresses it in later versions.

    yup, according to the bike mechanic, it was fixed under warranty. I bought the bike new in '14.

    The second wheelset I had built, I bought an older 2010-11 N360 hub, never had an issue with it. It was brand new and paid $150 for it!
    In case anyone is wondering, you can convert the older model to be compatible with the newer models cable end hardware...
    The older model has a "keyed" nut holding the mechanical hub interface in place. The newer hubs (2012 and newer) use a splined nut to hold the mechanical hub interface. Replace the keyed nut with a splined, buy new mechanical hub interface (I think it was about $30) and the wheels can be swapped without changing cable end hardware. Also the newer hub interface is a much better design.
