Sea Otter - The Hive - Chub hubs and Fifteen G Cranks

 Polygon: In geometry a polygon (pronounced /ˈpɒlɨɡɒn/ or /ˈpɒliːɡɒn/) is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain).

That crank interface sure doesn't look like a polygon to me, and the "100% surface contact" is total BS, but if the weight is truly only a few grams more than XTR at that price, they might be worthwhile.

Not sure if I really believe that a carbon hub shell transfers more load to the non-drive side than a single-piece aluminum hub shell, but again, sort of a cool idea.

Seems like there's a lot of marketing BS in the video, but some potentially promising products.

 Ummm? Cranks are sort of pressed on. You use your you tighten that bolt and it pulls the crank onto the spindle, just like square-taper. Thus why you need a puller (or in this case self-extracting) to get the arm off. I agree that 100% is impossible to get, but hey 99% is close enough.

"All the cool kids are running them" is a joke, people need to be less serious about this stuff.

Large flanges have been around for a very, very long time. Not a new concept, they just look ugly as sing, and most of the time the extra weight just isn't warranted. We shall see with this one.

 I've already seen these cranks in action and in my hand. They really are nicely made, very light, and look the goods. You know how sometimes you get something in your hands and you know it is well designed and you just know it when you see/feel it? Well these give me that sense of quality.

Some of you MTBers may have not noticed that ALL road bikes are going through a phase where the BBs are being redesigned to maximise bearing size, spindle diameter and crank/spindle interface. Why? To maximise the input from a riders MUSCLES. Surely the force put on a set of cranks when one does a decent drop is a lot more than a roadie in a sprint. Case in point: I've never pushed hard enough on a pedal to hurt my ankle!

The shape makes sense. Doubters should first read the literature presented by mcrammerstein above. Some industrious Germans have done the tests. Is it overkill for bikes? Dunno.

 I'm with k2dan - "all the kool kids are rocking them" has got to be the dumbest reason to buy something, and probably the most condescending thing you could say in a marketing video. jeez.

 A lot of the tooling at work (machine shop) uses that style of fit. Mostly on high end boring tools. Should work quite a bit better the square taper, if they make them to the right tolerance and shape...

 First of all; that is not a polygon. Any engineer or company that decided that should be called a polygon can't be trusted to handle the most basic engineering tasks because that's day 1 trigonometry. Also: WWII tank transmissions? Give me a fvcking break. When we entered WWII we only owned 1 model; the M2. It was terrible. So they rushed the development of two M3s, an M4, and, eventually an M5. All of them had MAJOR design flaws and were phased out soon after the war. The M5 was so dangerous to it's crew that several men deserted rather that be forced to work in that death trap. Bragging about copying their design is stupid. Almost every car manufacturer in the world has realized that splines are the way to go on torque transmission shafts. Why can everyone just get over their own bullshit and use a small spline with a pinch bolt ala shimano? It CLEARLY works.

I'm sick of all this bullshit over engineering. Over engineering sucks. Can't we just not mess with things that already work and spend our time on actual problems?

 idk, i think these things looks pretty sick, the large sized hubs to cut down on spoke length seems ingenious. its weird that nobody has come up with that yet. the crank seems pretty legit too, id like to get a close up look at some of that shit. but when it comes down to it, i think that that the majority of their marketing is just going to end up pulling in kids who like the graphics.

 lol, the Hope Biggun is back, but in carbon form - I really like these new products, and from an engineering point of view, they make a lot of sense - look like some really sold parts!

 I think the designers at this company need to revisit simple mechanics with that BB/Crank interface. What a farce, what marketing hype!!! 100% surface contact? BS!! That's impossible under load, not to mention that if it's 100% contact, do you have to hammer them on? I'd guess no, so even with exacting manufacturing tolerances, it's impossible to even suggest that 100% contact is possible, let alone achieved.

We've already learned this lesson with square tapered cranks. Enough of this marketing hype and 'new ideas' just for sake of being different. Make something worthwhile. Pure marketing BS.

 why doesn't somebody come up with a tapered bearing BB?? that way with these 2-piece cranks you can someone who didn't read the directions can really crank down on the crank bolt and not worry about over-stressing the bearings like with the cartridge ball bearings.

 One more: We already tried the huge flange thing in the 90's. Ohhhhh the 90's: The time of "standards" used by 1 company, neon colors, spandex, and a million ill conceived engineering "revolutions." When you build a wheel with a large diameter hub flange it increases the angle of the spoke and increases the stiffness of the wheel and the spokes because it changes the angle that the forces work on the spokes. It also significantly increases the strength of the hub flange because it's pulling more to the side of the flange rather then straight out when there's less metal. The problem is the spokes sit at too much of an angle in relation to the rim. This puts all the pull of the spokes on 1 side of the spoke hole. Failures of the spoke holes were very common with large diameter hubs back in the day.

 Dude! Don't tell me what I'm going to be stoked on!!
That crank interface is not a polygon and could be called a tapered cam or a three sided ellispe (also with a taper). It appears to be a larger diameter than the old square taper which gives it a bit of a chance to be strong enough, but I don't think i'm ready to buy. The larger diameter axle is welcome though. We need to figure out the largest diameter that can be used and make that a standard. A real standard, not the splintered faux standards that we have now. The largest diameter we can get would probably use needle bearings to take up less space and carry more load.

 Built - Transmission ~ ~ in our country's very expensive to sell. . . Moreover, the easy mechanical failure. I feel no need to use this ~ ~ it's easy to use chain drive

 well the crank interface should be strong, it wont ever strip but the designe means that the cranks will split if there is a large enough load put on them.

 yea, he said bigger spindle allows u to run a bigger diameter bearing. bigger inside diameter which means a smaller rolling element. Which is opposite of what he said.

 we need datas, don't need the marketing shit... "a few grams lighter than xtr" - how much???
as i see you need a new tool for the BB... not good for a small company...
poor guy got hard time due the video

 but all the kool kids are rocking them ,wtf those that mean im not kool dam i need those hubs

 The thing about applying designs from other devices is that there are different design considerations with bikes. How many tank transmissions USE ALUMINUM SHAFTS? And how many tank designers are weight weenies like bikers? I know weight is a consideration with tanks, but they're not shaving grams like bikers. How many boring tools are made of aluminum? And how many of those are in weight critical environments?

This whole enterprise is marketing BS, and I'm surprised that since the entire thing hinges on marketing they didn't see fit to hire a better rep.

 i personaly dont like the look of them hubs...way to big and plane looking...ill stick with my Industry Nine but its good to see new companies out there trying

 sick!

 I wish the hubs came in a cassette interface instead ye old thread-on freewheel.

 all the cool kids are rocking them. thats a good way to sell em?? ahaha not

 LoL 100% contact with cast crank arms I think not. The hubs are pretty nice but the cranks need some work.

 come on, drink the Koolaid. OHHH YEAH!
