    Son 135mm hub dynamo!

    Expected by July: Schmidt Maschinenbau News and a picture: http://www.m-gineering.nl/son135-2.jpg

    Life starts looking good for electrically challenged fatbikes

    Have used a 100mm version in my fatbike and am quite pleased with it. You don't notice any drag and your GPS doesn't run out of juice anymore mid-way in a bike-packing trip

    Very cool! I have these on my commuter, big dummy, and 29er (thru-axle version). The only real downside has been the price. They just keep on rolling, and using a dynamo hub (Shimano, SON, whatever) is fantastically convenient.

    Now if they'd just make a lefty version.

    Very cool. I just got a dynamo equipped road touring bike finished, it is sweet. This is fine news.

    Just when I had finally decided I would just have to go a little narrower for a dynamo this happens... Any word on the expected price?

    very good news indeed. Watching for more details. Will be interesting to see how robust they are - want to be able to bash the bike to all hell and still have it work. Also need it to be able to survive full immersion without playing up. Suspect this is unreasonable though ;-)

    My buddy Billy (arcticcycles.com) ran one of the two original prototypes on his 2,000mi odessey on the Iron Dog trail. No disapointments I'm told.

    I used mine (a 100mm one) on a recent trip 1 week trip in Sweden that involved lots of bush wacking and the occasional involuntary water dunking. No trouble whatsoever.

    With the discontinuation of the 100mm Pugsley front fork, this is looking like a suitable alternative. I'm about to order a new Pugs and being able to move some of my B&M lights to the Pugs and not buy $300 worth of new battery-powered lights will offset a good chunk of the cost. I just asked my shop to quote adding one to the build for me.

    The CQ Cyo-Rt is nice, but the Luxos is incredible!

    How do I fit my front wheel to a 100 mm fork? My rim is a Clown Shoe and the tire is a Bud.

    Saul...the move away from 100 to 135sym came about because folks didn't like dropping air pressure or removing the caliper just to get the wheel in or out of the fork. I switched to a 203 rotor on a 100mm Blacksheep Ti Unicrown to get around most of the issue without switching to 135sym...

    Right, so the fact that I can mount a wheel without removing the caliper and dropping air pressure (and I'm still suspicious as to whether the Clown Shoe and Bud will fit) is "zero benefit".

    Yeah I know Lars used the weasel-phrase "in my view". I'll let you in on a little secret: nobody gives a damn about your view. Take your negativity elsewhere. There's a number of fat bikers with 135 mm hubs in front out here and for us a dynamo hub is good news. We don't need to hear about people who don't need it, because if you get into that there's a few billion people who have no use for a 135 mm hub dynamo. The point is that quite a number of people do like to have this option and it's about time someone started making one.

    Don't need one? Don't buy it.

    ...pretty sure it (Bud/hundie) would fit in my Ti BS, though I'd probably have to go back to airing down/removing caliper...not excited about that. Bud/hundie quite probably won't fit in a Surly 100sym......that being said, my buddy loves his 135 SON; I'd start meandering down that path, but between three wheelsets w/100mm SON's and two fatties w/100mm Ti BS, It's way too expensive for my GF and I to change to a new standard that hasn't even established itself yet...135 w/QR is already as outdated as my 100 w/QR...TA is where "it" is at...but which size/width is "it"...and then SON has to play catch-up, which they may be hesitant to do as they just got left in the dust with their newly released bit of hardware that was already obsolete four months before they released it...

    well, I may have some more details about this soon. Just asked my bike shop to put together a build using this hub. They're going to see if they can source it, probably going to go direct Peter. Anybody else tried to buy one yet? Wonder if they're available...

    Yeah, it is really pricy right now. But I already have great lights to go with it, and not having to spend 200-300 on new battery lights offsets at least half of the cost. And not needing batteries for winter commuting is worth it to me. Ymmv.

    understood, I would probably have one of the 15mm Son hubs if I had a bike to put it on. But this one looks like a much simpler modification to the regular hub, I wasn't expecting a premium over the 15mm. The usual suspects online don't seem to have the fat bike hubs yet. Usually, Peter White will say if he doesn't have something

    Ahh, got it. Frankly, if Surly still made the 100mm fork I'd probably go with that (although fork + Alfine Dynohub approaches the cost of the SON 135). I suspect that the $50 premium over the other hubs is just due to small production runs... if we buy them, hopefully the price will come down somewhat.

    There are a few 100mm 29'er/fatbike fork options that I know of...BlackSheep Ti Unicrown (easily fits hundies and 4.0's, possibly 5.0's too), Blacksheep Steel Unicrown (easily fits hundies and 4.0's, quite probably 5.0's too...there is a ton of room between the legs), Bontrager Switchblade (max is 65's and 4.0's), Surly (max is hundiess and 4.0's...barely)...not sure what else...actually, you could also try DeSalvo, they are no stranger to fatbikes as they built Wildfire's frames for a number of years...I'm sure there are a ton of other rigid 29'er forks that would work with the mid-fat range (45-65mm and 3.0-4.0's).

    ...gottcha...A rear gen hub would be cool too...I thought I found a Shimano rear gen hub right after Billy and I started looking into gennies for our fatties 8 years ago, I figured it was some obscure euro offering none of us had ever heard of...turns out it only turned out enough juice for the early generation electric derailleurs...oh well...I wonder how much generating capacity you could cram into 190mm?

    you could easily put a full-wattage generator in even a 130mm rear hub (first, buy a component factory...). The generating parts of the SPs are tiny.

    Just to confirm, that 135 SON hub won't allow you to pedal if you need to swap out hubs front to back in the middle of the wilderness, right?

    You could skin that cat:

    Problem Solvers Centerlock Adapter
    +
    VeloSolo 6 bolt disc rotor flange cog

    Noteworthy: normally I would recommend getting the actual Shimano made centerlock adapter because their machining is precise and any disc brake rotor you mount to it will rotate true. This is not the case with the Problem Solvers adapter, it ends up wobbling a few mm throughout hub rotation. However, the Problem Solvers adapter retains the flange threaded holes, which is important in this particular case you bring up because I'm not sure that the Velosolo cog and a standard disc rotor have the same thickness... and the thickness is very sensitive when it comes to the Shimano made adapter.

    Interesting ... but would that work with the Pugsley offset? You'd have to flip the wheel around to get the brake rotor on the drive side.

    If you cared that much about having a front brake in those conditions, yeah that might be an issue. Don't know about you but I've been in snow that's hard to pedal going downhill and the front brake was the last thing on my brain...

    No I mean you'd have to flip the wheel around to get the brake rotor mount on the right side so you can mount your cog on it, in line with your front chainring. But the offset would be backwards. Maybe I'm missing something.

    You're not missing anything. I'm saying to make the offset work you'd need identical offsets (Pugsley) and sacrifice the use of a front brake because your front brake flange (in the form of the SON) would be on the wrong side all the time.

    Or else be willing to mess with bolts and sh!t in the snow, bringing spares and what not.

    But! But... this is all irrelevant when you consider that Fatback et al have concentrated on a symmetrical rear that has no regard for swapping wheels, using very low viscosity lubricants during the winter in Alaska and more typical lubricants in the summer. I've never had to do the wheel swap thing but I only live in MN and my temperature floor has been, practically speaking, -10F, which doesn't even touch temps farther north...

    Probably not. On the other hand, it looks like there is a bunch of space free on the non rotor side of the hub. I wonder if Schmidt might turn the hub into a full geared rear hub someday

    It's pretty mountainous where I live so I need a front brake. Last year I was flying down the hill at 30 miles an hour on the cross country ski trails. It would be pretty easy for SON to put another brake rotor mount on the other side of that hub. Doubt it will happen though.

    Does the Son Dyno require a spacer to move the caliper inboard? It looks like the just extended the axles, not the hub body.

    My LBS just sent me a picture... a viewpoint that I haven't seen in any of the online pictures yet. We have decided to lace it to a Holy Darryl, since it will be for snow commuting.

    Son 135mm hub dynamo!-son-dynamo.jpg

    Is it just me, or does the right-hand half of the hub cry out: Why is there no spline here for a SS Cog? Seems like it shouldn't really take any extra manufacturing to put it there instead of the extended axle. I'm getting it put in a symmetric front so it doesn't matter for me... but it would be interesting to get the very first dynamo rear-capable hub out there.

    I already own a B&M IQ CYO-T and a B&M Luxos-B. They are both awesome, but the Luxos-B definitely has the edge. Most likely it will have the CYO-T on it while I'm primarially commuting on my cross-check, and once the snow drops and I'm commuting on the Pugs I'll probably swap it with the Luxos.

    Waiting for the Pugs frame to show up... LBS is guessing mid-Oct, but with the recent "my bad" that Surly sent out, they aren't too sure either. Trying to get better data from QBP and Surly. I'll definitely be getting you some pictures and thoughts when I finally get to ride it.

    I'm putting mine together too. I have the frame, fork, brakes, BB, cranks, Alfine 8, and an old XT rear hub I'll use for the front. Tomorrow I'm going to the States to pick up my Rollin Darryls (they were all sold out for months and I got the email saying 40 were in stock. I immediately ordered them and within half a day they were sold out again). I order from Universal Cycles which is really good.

    It's a lot of fun putting it together myself.

    It would be really awesome if they could put a SS mount on the other side of that SON hub, that would just complete the setup. I think I will email them and suggest it.

    Well, the truck with rim strips didn't show up at NCC by the time I got there this morning... I'm heading back in a few weeks when the wolvhammers show up, so I'll have to wait to ride the new wheel until then. However, I now have my SON 135 built into a Holy Darryl... Wish I could ride it though!
