@somebody-else: to do sized chain stays on most bikes you move the suspension points relative to the BB, but this bike has a concentric pivot to the BB making that impossible.

@hllclmbr: The dropouts are not Paragon. They are Revels own design

@theobviousfaker: HTA is the steering axis, which is determined by the frame. The head angle does not change through travel, however the fork offset does. That is the perpendicular distance between the wheel axis and the steering axis. That will decrease through travel, increasing the trail number

@dododuzzi: You have to post machine all of the lugs for where they interface with the tubes or any other part. Not saying one method is more or less work, but it's not as simple as press print and you have a finished lug.

@dungeonbeast: Not the person you responded to, but I can answer. It depends how you measure kickback, most people measure pedal kickback with the brake unlocked and the bike on the ground compressing the suspension vertically. In this setup you get kickback from two sources. The first is the the distance between the top of the front chain ring and the rear cog increasing. As you said in this setup the chain wraps around have front cog to feed more chain into that space causing the cranks to rotate upward. The second source is due to the fact that the wheel can rotate. When you compress the suspension with the brake unlocked, the wheel will rotate backwards relative to the rear triangle. This will then cause the crank to rotate back as well. This is partly why bigger cogs have more pedal kickback, the degrees the wheels rotate are the same but the bigger cog means more teeth, which also means more teeth that the front cog will rotate back. That being said, while rolling this does not cause pedal kickback, since the rear freewheel is engaged. And when the brake is locked you will actually have the back of the bike try to rotate the cranks a bit forward instead of bike with a concentric setup. So yes pedal kickback with a concentric pivot, but only on paper and not really on the trail.

@blueninja: Check out linkage or syn bike, these are dedicated tools for figuring out suspension kinematics on MTB's. Once you have the points you want you can then bring them into your preferred CAD program. And Vorsprung suspension has some of the best videos to help you understand suspension concepts on Youtube.

It's probably that there is now a very robust off the shelf solution that fits nicely into frames. If you look back at most of the frames here, they have to either develop their own gearbox or run a second hub and chain to get a gear box. With off the shelf solutions like pinion companies don't need to develop their own which saves on development time, and the packaging makes it possible to use more conventional suspension designs and frame layouts.

@Newgame2113: I think that's Orange Vise Company

That's how you charge the battery for the pinions shifting
