Canfield Unveils Jedi 29 High Pivot DH Bike
So you’re telling me that you think their claiming it’s generating free energy? It’s about losing less energy. This thing is going down hill. Without obstacles, you will accelerate. That’s just how gravity works bud. The kinematics are simply trying to negate how much they slow you down. The less your kinematics interfere, the less forced due to gravity is lost. And if you have terrible kinematics & axle path, you're going to lose more energy. Therefore, assuming one bike loses more energy than is imparted by gravity and another loses less, the bike that loses less will accelerate while the other decelerates. High pivot bikes just simply lose less energy through obstacles, hence less deceleration and possibly allowing acceleration. Gravity is a pretty neat thing for imparting energy.

Trek Domane 4.5C
$900 USDIm selling my 2015 Trek Domane 4.5 Compact because its a few sizes too small for me and I just don't ride it any more. The bike is in great shape and has always been well maintained (I work as a bicycle mechanic). I'm including a pair of Look Keo Plus pedals, a Bontrager Node 1.1, and a Garmin cadence and speed sensor. The bike has Ultegra shifting and 105 brakes and cassette. The tires and bar tape are in good shape and still have plenty of miles left in them.

Trek Debuts New RE:aktiv Thru Shaft Shock Technology
@sparkylab: Interesting. I wonder if these shocks don’t have a gas pressure in the oil expansion chamber. Something gotta keep it from simply flowing into the chamber during compression and rebound

Trek Debuts New RE:aktiv Thru Shaft Shock Technology
@MX298: I agree. I would be worried about cavitation I this shock, especially if you start working it hard

Trek Debuts New RE:aktiv Thru Shaft Shock Technology
I think there is very little hysteresis in the DVO shocks from what I have seen. Also, super low hysteresis is not something that is overly important in mountain biking asour bumps are not as small nor as minor as those in cars. If you watch the video by Steve from Vorsprung he explains this in finer detail.
