9/11/2017 9:57pm That 'one of the women' is none other than Jenny Rissveds, the olympic champion. I also doubt Marcelo blacked out the Giant logo, since it's prominent on his leg and is his factory ride, it must have been some other sponsor on his national jersey that isn't kosher with it being there and having a factory Giant ride.

Wait, where does the bearing sit on the crank axle?

This is what i was thinking,t he chain is constantly being centered on the chainring, if you're not pedalling, it can get misaligned a bit, even more so at the bottom, it starts comming off and before you know it, it's completely off. With the rear end moving around, the same can happen in the front, if you don't have a chain guide.

But when pedaling, the chain is under tension and less likely to pop off, and that clutch looks like it was overtightend just for this demo

9/6/2017 10:41am Well of course he would. And then he could say he will retire. Audi was saying they will race in the 2017 WEC championship and had a car designed, when the bosses pulled the plug. Same with Porsche, they were saying they are staying, until after Le Mans, when they announced they are quitting. You don't announce everything until you...
Primoz Added a comment about feature Pinion's 12-speed, 600% Range C1.12 Gearbox
9/4/2017 9:57pm
I've actually contacted the guys at Effigear, regarding backpedalling and pins releasing and so on, their bikes don't have a freehub, which enables you to shift without backpedalling, since the chain (or belt) drives the gearbox. If you had a freehub, you'd have to backpedal for the output gears to effectively rotate faster than the input, releasing pins. If you'd use a chain tensioner, you couldn't have a freehub-less rear wheel, which means the chain wouldn't drive the gearbox, which would mean you would have to backpedal. This is straight from the horse's mouth. Using a tensioner and having no...

But Effigear has issues with maybe not enough gear range (460 %, should be okay though), but it only has 9 gears, which means quite large jumps. This is due to a direct 1:1 gearing configuration (there are 9 gear pairs to cover 9 gears), while Pinion uses 2 gear stages (3x6, 3x4 or probably 3x3 gear pair layout for 18, 12 or 9 gears), which means they get 18 gears out of 9 gear pairs. The other factor, that i have issues with, is that the wheel needs to rotate the gearbox in order to shift in one direction...

This or a frankenstein blackbox mating an Eagle shifter to the Pinion gearbox.

What size is the weehlset? 27 or 29? That's 42T cassette in the rear, right?

4/14/2017 11:24pm You have a very good point here about opinions, one I should follow as well. But I can't get out of my skin :-D As for damping, bikes aren't much different to other vehicles, moving systems need damping in order to prevent unwanted oscillations. The only issues I can see with bikes are first that the rider plays a significant...

4/14/2017 11:17pm The damper is a bolt on addition, it's not integrated.

4/14/2017 3:16pm I find it funny how Voss claims his design needs almost no damping while Jose says that a system needs damping in order to function. I think i'll stick with the opinion of the guy, that worked with MX bikes, designed shock absorbers and has developed many race winning bikes over the opinion of a guy that designed URT mountain...

4/12/2017 12:52pm It looks to me that they went with a different design for the sake of being different. Also, this is kinematically relatively simmilar to Yeti's Switch Inifinity, a linear slider with a link for guidance. So still a four-bar design. The general layout is different of course. I also love the fact that the designer bashed marketing, but Dirt then...

3/21/2017 10:15am Not external, it's a different stamping process. But maybe it'd make sense to just curve the outer plate so it narrows in the middle, you still need more material than for a flat plate, but less than for a thicker plate. Though, how will that work with shifting ramps? This might be just a patent covering the possibility with no...

3/16/2017 10:49pm You would, you wouldn't have anywhere near the balance and momentum needed to ride up obstacles with a 22/52. Riding technical uphills is not a low gear ratio game, it's a 'you need enough power and stamina to not use the granny gear to have enough speed' game. Even a 22/32, based on my experience, is often not a high...

3/13/2017 2:29pm That is an interesting question, but i wouldn't be surprised if it didn't work for some reason. If nothing else the Pike or Lyrik, which i would prefer, has a 15 mm axle. BTW, i was thinking back in the early 27,5" days that if you'd take the old Lyrik (Mission Control) and put 27" Boxxer lowers on it that...

3/13/2017 1:54pm Hm, good point. And yeah, having a 29 in the front would be better. Even more so with the high pivot rear linkage design which moves away from the obstacles. But how many 29" DH forks are out there?
The bike still looks short though, so i wouldn't be surprised if it's running a steeper HA for a 29"...
