Pinkbike Poll: Which Major Component is the Least Evolved Part of a Mountain Bike?
Gearboxes are a major area. One piece carbon wheels, not spokes, made to be lighter, stiffer and not ever go out of true. Suspension damping. Shims are on their way out replaced by newer, patented cone valve technology that outperforms them and outperforms electronic suspension. Rear suspension. Light weight carbon springs will allow rate curves to not be compromised by crappy air spring ramp effect with minimal weight gain, if any. Combined with the cone valves, platform style damping will be more seemless and not need VPP style curve manipulation that negatively impacts bump absorption. Lastly, more rearword wheel travel, as is becoming the trend, to improve square edge bump absorption while also helping eliminate pedal bob. Better suspension performance, feel and no need for climb modes. Set it and forget it, yet perform better in all aspects. Dropper post reliability and both direction actuation.

Pinkbike Poll: Which Major Component is the Least Evolved Part of a Mountain Bike?
@Bustacrimes: Explain how we are being conditioned to want gearboxes? Name the last time one of the big drivetrain manufacturers told me gearboxes are the future. Name the last time one of the big frame manufacturers told me gearboxes are the future. Name the last time Pinkbike or another bike publication told me gearboxes are the future. Name one top 5 or top 10 factory racer using a gearbox. Sorry, but the big drivetrain manufacturers have majorly resisted gearboxes and consistently reaffirm their stance that derailleurs are the way to go. Not a single one of the big frame manufacturers makes a gearbox mtb (not e-bike). And all the articles about gearboxes have either been just "here's some pictures of the latest gearbox we say at Interbike" or articles blatantly expressing reasons why gearboxes won't be the future. All the top factory riders are running derailleurs, unlike what you seem to think. The reality is YOU are brainwashed. All the major corporations are pushing the narrative you are repeating. It is RIDERS that want gearboxes and tiny startup brands building gearboxes and gearbox frames. Yes, there are current downsides like weight and drag, but many upsides. The amount of money thrown into their development is tiny. There was a time people like you resisted disk brakes because they were more complex and heavier. Going from u-brakes to v-brakes was evolution. Going from rim brakes to disk was a revolution. Going from 3x10 to 1x11 was an evolution. Going from derailleur to gearbox will be a revolution. Current drawbacks will be sorted when you quit resisting and we finally have development money funneled to advancing the technology.

All About Unno - Most Interesting New Bike Brand in the World?
Lots of drooling by the editor and comments. But is it any better? Yeah, it's made in-house and looks pretty, but does it perform different? I don't seem more drawn to it over many other brands (YT, GG, etc) even if it was price competitive with them. Maybe some refinements in frame layup, but is that it? $5k for a frame to get some slightly different flex characteristics. Looks good, and I'm sure it rides good, but for the price and hype I was hoping for some actual innovation.

First Look: BREW Nitro Shox - Eurobike 2015
@hamncheez: Preload is good, but unfortunately the biggest factor in setting up a shock spring is spring rate. Without proper spring rate the preload and damping will have to be used to compensate, which equates to bad performance. It happens all the time on road motorcycles that come with way too soft springs so damping is increased to keep it from diving. The result is a fork/shock that wallows on slow speed bumps and is harsh on high speed. Going to a stiffer (correct) spring rate allows lower preload and damping so the suspension stays higher in the stroke but can absorb high speed impacts. Now as you said, race trucks don't change weight throughout a race, so why would you want your spring rate to change throughout the race? Same on a bike. Your weight from top to bottom of mountain doesn't change, so why should your spring rate (and preload) change as you ride? It's not good, that's why Nitrogen is beneficial. The spring rate and preload stay more consistent with what you set it at at the start of the ride.

@benwearsahat: Not really what I was talking about. Volume changes are done separate from pressure changes. Change the volume to the correct for your weight, THEN adjust pressure for sag. pV=nRT comes into play after it is sealed an operating on the bike. The unfortunate thing is no one builds a shock that separates spring ramp up from spring rate which leads to setup issues. I've already argued the benefits of nitrogen, so you don't need to tell me.

As the shock goes through travel, the spring force increases, just like any other spring. This does not cause an increase in damping (position sensitivity). Damping only knows the pressure difference over the piston, not the total pressure in the system. The needle system sounds more like a position sensitive device that adjusts bypass. The further in the stroke, the less bypass, so more damping. Likely meant to affect only compression and not rebound. Rebound you want opposite to keep you higher in the travel so you have more travel to utilize, and thus can make it softer without bottoming. Digressive is NOT the same as position sensitive. Digressive damping has to do with shaft speeds, not position. Also, shape of the bump is what changes suspension feel, not the size. Damping is speed sensitive.

First Look: Fast Suspension - Eurobike 2015
Right, and technically he never said it was chatter marks either, rather it should be an available finish like you said about tweed. Maybe he thought of it because the unfinished look, or maybe he did think it was. His comment didn't say that specifically though, so no need for half the comments to call him names without knowing what he meant.

As a side not, that shaft isn't DLC coated, like stated. And just because they couldn't get twin tube to works doesn't mean it doesn't work great. Ask anybody with Ohlins on a dirt bike or Ohlins or Cane Creek on mountain bike. Single, twin, both can work great.

Read the first comment, then read properp's comment. I don't see him saying the current finish is chatter marks, just a joke that it should be available finish, you know, following the tweed comment (no one yelled at that person saying it isn't tweed). Anyways, finish passing would be nice, for looks, cleaning and it will be lighter. And stronger considering there would be less stress risers.
