Added a comment about feature TECH TALK: Air Shocks Versus Coil Shocks, What's Better? 10/15/2017 11:19 AM

Under the description header in that wikipedia link "A process that does NOT involve the transfer of heat or matter into or out of a system, so that Q = 0, is called an adiabatic process, and such a system is said to be adiabatically isolated.[4][5] The assumption that a process is adiabatic is a frequently made simplifying assumption. For example, the compression of a gas within a cylinder of an engine is assumed to occur so rapidly that on the time scale of the compression process, little of the system's energy can be transferred out as heat to the surroundings. Even though the cylinders are not insulated and are quite conductive, that process is idealized to be adiabatic. The same can be said to be true for the expansion process of such a system." So essentially under high shaft velocities the heating has little/no/less time to occur whereas lower velocities experience heating....and presumably a higher rate of pressure gain through the stroke. So basically the opposite of the heating process occuring at higher speeds.

Leverage-wise the endorphin is way more progressive. "Progressive" just means the ratio drops through travel. Obviously there are huge varying degrees of that. Like I said, the digressive hook is really the big no no with going with a coil shock.

You'll be fine with a coil on a scout. Like you said it's not as progressive as a patrol with the newer metric shock link but it's still mildly progressive. The thing you really want to watch out for is the fall off/regressive crap that some frames have ... more »

Depends on the bike. Like longwind said above, bikes specifically designed for air shocks tend to try and negate the inherent ramp up at the end of travel with air springs. Since coils do not, this makes 'most' coil shocks allow hard bottom outs on those ... more »

There's a clue nearby. See if if you can find it. It's not far.

Aw come on man, what's with the sped up footage? Just like Rankin used to do. Sheesh.

I've seen mountainbikers in 2017. This is an absolute necessity.

What year was that 'forward geometry' mondraker dh bike where he thinks it was the first to drop below a 65 degree headangle? Cuz I know of two others.

Not to add insult to injury but there's a really fun degraded road to the north of the current silver canyon road. It's pretty much singletrack now, kept open mostly by moto traffic but it's the 'old road' before they built that steep switchback mess. ... more »

Thank goodness a new 29er tire didn't have any bearing on the outcome this year. :D

Nah, just the lesser of two evils apparently.

OR....... These last two tracks are what everyone agrees should represent real dh racing tracks, instead of ones where just holding on and pointing in a straight line between groomed berms wins. So the real dh bike comes back out.
