Paragon Machine works 12mm dropouts 100mm (4)

In terms of far reaching implications for the industry as a whole, one of the more interesting tech items at NAHBS earlier this year came in the form of prototype hubs from Chris King and a fork from ENVE. Specifically, it was the fact that the axle size was yet another addition to the world of axle “standards.” The new 12x100mm combination hinted at the future of disc brake road, cross, and gravel, but it’s been more or less limited to prototype show bikes to this point.

Now, with the latest introduction from Paragon Machine Works we’re getting a glimpse into the future. Something tells us we’ll be seeing a lot more of the new 12x100mm axle size this fall…

One of the beautiful things about custom bikes (aside from their inherent beauty of course) is the fact that builders can change features of the design at a moment’s notice. Without having to wait for new tooling to be created at a factory far away from where the bike is built, with the exception of some possible changes to their frame jig, custom builders can quickly adapt to new standards. That is, as long as raw parts for those new standards are available. Having made a name for themselves with all of the small bits that add up to to a complete bike, Paragon Machine Works is usually off the front when it comes to new designs.

That seems to be exactly the case with their new 12mm front dropouts and new thru axles. Starting with the DR2052, the flat/tabbed dropout is machined from 4130 steel and is meant to accommodate up to a 15mm diameter tip on the fork blade (not to be confused with a 15mm axle).

The other two sets of fork dropouts (DR2054 and DR2055) use a flanged design and are machined from 1018 steel with a 1″ outer diameter. The 2054 is narrower at 18mm, while the 2055 is 24mm wide to allow for a wider fork blade. Paragon mentions that if builders are looking for a large diameter fork blade for the build, they should still use the current 15mm dropouts and 15mm thru axle skewer. Paragon claims all three dropout designs weigh less than their 15mm dropouts, and the heaviest 12mm dropout is only 5g heavier than their lightest 9mm dropout.

While Chris King made their intentions for a 12mm ISO hub clear at NAHBS, Paragon tells us other companies are following suit. Apparently Industry Nine will have 12mm versions of both their Torch Classic flanged hubs and their Torch Road Disc System wheels this fall, along with 12mm hubs from White Industries and Paul Components. We won’t be surprised for that list to grow come Eurobike/Interbike.

Since fork builders will need some sort of thru axle/skewer to hold the new hubs in place, Paragon is offering two different options in 12×100 sizing. First, Paragon’s own bolt-on skewer is turned from 6061 aluminum bar stock and includes a 6mm tall head that includes both a 6mm internal allen fitting as well as 15mm external wrench flats. Lighter and cheaper than existing skewer options, the M12x1.5 threaded skewer checks in at 37.4g and sells for just under $20. The same design is also available in 12×142, 148, 157, 177, and 197mm lengths to cover the spectrum of bikes including Boost and fat bikes. Soon the hex head skewer design will also be offered in 15mm diameters as well. Paragon is also selling a 12x100mm version of the DT Swiss RWS skewer which measures in at 62.1g and sells for $31.35

I really just want to know why…

It’s very hard to understand why 15×100 needs to be replaced for road. Given that it does, why not 9×100 instead? Such a design would be compatible with some hubs already on the market and would be compatible with existing dropouts using a 9mm through bolt that you can buy today. Is 12mm really better than a 9mm through axle for road applications?

This seems like the most gratuitous, least justified new standard of all with the possible exception of the idiotic disc brake flat mounts. Perhaps a tie. Makes Boost look like genius.

Buying a wheelset will soon require a master’s degree. Hub spacing, thru-axle diameter, 8/9/10/11 speed compatible, rim vs disc, centerlock vs 6-bolt disc. That fork-mounted roof rack is going to require adapters too!

12x142mm rear and 12×100 front seems to make sense. 15×100 is probably overbuilt for road purposes anyway, but why change platforms just for the sake of changing them?

wuffles

Why? Just…. why?

15x100mm already exists. Now we’re gonna go 12mm? Because of some miniscule weight savings? Actually, scratch that- I bet 12mm is actually going to be heavier, just like 31.8 mm bars are actually heavier than the 35mm bars. This is a stupid standard on all fronts.

In 3 years some company is going to come out with a 15mm front end and claim it’s “new design is 23% more stiff in the corners, while saving weight!”

If you recall the initial blurb on 12×100 said the reason was basically that for some reason manufacturers didn’t want mountain and road parts to be compatible.
no idea why, but it’s a reason. Not a good reason…

12 x 100 is just stupid – its actually heavier than 15 x 100 – just like the example of the bars from Wuffles.

Most of the Road and Mountain parts will/are going to be compatible because its going to be a simple axle or end cap swap. Wheel makers aren’t going to completely redesign their hub for something I can shim their 15mm to 12mm that would just be stupid… but then again it would go inline with the whole idea of 12 x 100 anyway…

You can thank one of the bigger names in cycling for this one.

Complain all you want but it’s coming whether you like it or not. Just about every single hub mfg of note not listed in this article have been prototyping 12×100 for the last year or more. Amazing how many people think that the industry should just stagnate and there should be advancement in tech whatsoever. There’s always going to be curmudgeons that just gotta poo-poo anything new, but it sure makes for great comedy. Synthetic chamois, clipless pedals, STI, disc brakes, aerodynamics, carbon, axle, headset, and BB standards, etc etc were all considered “unnecessary”, “overkill”, any excuse to complain by the friendly neighborhood Luddite contingent. It’s just a ‘marketing conspiracy’ to get you to empty your wallet, right?! Hey, I have a great idea! Let’s revert back to wing nutted axles and push rod derailleurs. You game? Heck, just give me a dandy horse and I’ll be on my way!

Because a 14mm axle is ~15g lighter than a 17mm axle. LOL.

@Kernel Flickitov

We’re not talking about QR vs thru-axle, we’re talking about 12mm vs 15mm. The existing 15mm standard is both lighter and stiffer, and has a whole bunch of hub options already available. 12mm is an inferior design that isn’t compatible with a whole bunch of existing hubs. That’s nether innovation nor progress, it’s just money-grubbing.

I wonder if liability plays into this… Somebody might have decided that they could get sued by someone who put a mountain wheelset on a road frame, rode it off road, & hurt themselves due to a component failure.

(deleted), but they’re doing a voluntary recall of approx eleventy billion bikes because people can’t figure out the basic operation of a QR, so stranger things…

JBikes

I think people may be getting hung up on the 15mm vs 12 mm weight issue, looking only at the axle.
15mm TA do require significantly more drop-out than 12mm (obvious huh) and the resultant total weight may (or may not) be more. I know Giant has publically stated that the existing TA choices are way overbuilt for road use.

@wuffles, where in my post did I allude to that this is about QR vs thru? If you can find the exact quote I’ll bake you a batch of cookies. 😉 I know EXACTLY what we’re talking about, I currently have two active NDA’s with a hub and a wheel mfg, both US Co’s. If 12 thru is “inferior” why is every major and aftermarket mfg keying up to release it soon? Greed? Pffft, c’mon guy I’ve literally heard it all before. Like I said in my OP, sorry if you don’t agree with 12×100, it’s coming whether you like it or not. Years down the road 12 and 15 thru axles might phased out entirely by something else, but we can’t get to that point if we don’t try new things.

Keep in mind mountain 15mm axles are too long for road fork dropouts. ( I found out the hard way) So there would be a “road” 15mm front axle length and a “mountain” 15mm axle length. It’s not like they would be compatible anyway.

I think it sounds like a great idea. And really, how much weight are we adding? And to the center of a hub, at that. Weight isn’t important. It’s exercise.

BillBob

@Kernel – trying new things for the sake of trying new things isn’t innovation or advancement. It’s a step backward. It makes consumer and mechanic lives more difficult and offers no performance advantage. So why do it? Design something BETTER than makes the bike FASTER and people will be all for it. Designing something DIFFERENT simply because it’s different is regression. Let’s just start changing all kinds of parts diameters every other season for no real reason. What’s next, 25.4mm seat posts?? Oh wait…

@Kernel Flickitov

This isn’t some change resistant luddite thing like you seem to think it is, it’s purely about performance. I don’t give a d*mn if I have to buy new hubs, if there is a benefit to those new hubs. But 12×100 seems to be inferior to 15×100 in every way. Do you have any hard data on how 12mm axles are superior to 15mm axles? From a pure engineering perspective, the only reason you would go with the smaller diameter axle is due to space constraints, everything else is worse. There are plenty of road and CX bikes on the market now that are doing just fine with 15mm axles, why would I want a 12mm axle?

JBikes

Outside of CX bikes, that may stick with 15mm TA, there isn’t a big market of 15mm TA road bikes for sale. Adoption of 12mm for road is, at the very least, well timed. Normally, we’d get 15mm TA road bikes for 2-3 years then this would trickle out. As-is, not many will be hurt by road TA equipped bikes fitted with 12mm TA’s since they will be unlikely to have a pile of 15mm TA road wheels. One bright side yeah?

@BillBob, 12 thru is coming on line not for the “sake” of anything. You can misrepresent what I said and strawman all you want just like @wuffles, but the fact is the R&D and testing behind this has been on-going for a while now. 15 thru in the road/cx format isn’t leaving the scene anytime soon, it’s a perfectly viable system, and there are a bunch of frames out there built on that format already. And how is adding a 12 going to make anybody’s life more difficult, mechanic or end user? You build the bike to spec, simple as that. That’s in the same vein as saying ’44 straight head tubes as opposed to tapered will cause problems for everybody’. Just not true.

Weight: DT Swiss 15x100mm (79g), DT Swiss 12x100mm (63g), PMW 15mm dropouts w/ inserts (105g), heaviest PMW 12mm dropouts (59g)

Hub Compatibility: As people have alluded to, many existing hub manufactures can simply swap end caps on their hubs and they will be compatible with 12mm hubs. This means many of those 15mm front hubs/wheels you’ve already purchase will be forward compatible with the new 12mm specification. That being said, some hub manufactures will be releasing hubs that are specifically designed around a 12mm axle as end caps are not an ideal solution.

Paragon is viewing the 12mm as an excellent option for road, gravel and cross frames. As you will note from the above posting, these are only available in steel. My personal view on 15mm steel forks is they look massive on any frame that’s not a ~2″+ tire bike.

Personally I’m really excited about these 12mm dropouts, for my touring bike. Tapered head tube, 12mm through axle, 40c tires and some good old BB7’s seem like an excellent option for those of us still wild about fronts racks and panniers.

Thanks everyone for your comments/interest, and if you have any specific questions about these dropouts feel free to ask!

Aside from the conjecture and broad sweeping generalizations thrown out by both sides here, as a wheel builder I’m genuinely super anxious to try out the new 12×100 for myself. Won’t be the first time I built a bike around a hub set, imagine that! If you think about this objectively it only makes perfect sense in the road/cross/gravel realm. Thanks for cutting through the noise and giving us the real deal Sam!

12mm will have some aero advantage over 15mm on road bikes in both centre of hub thickness and bulk in the fork tips.

Hopefully when the UCI adopt disc, they will nominate supported specs, i.e.
– disc size: 160mm?;
– hub width: 100mm front & 142mm rear;
– hub diameter: 12mm front and rear.

Is this hub size thing going to be like when Cannondale kept making larger and larger tubes to make it lighter and stiffer to the point their frames were completely unrideable for more than 10 miles and your body would be numb and tingly?
