First Look: Cavalerie's Blackbird Carbon Gearbox Bike - Garda Trentino 2019
@connorjuliusjohnson: trust me, the grip shift is superior for gearboxes. Even if you shift accidentally, it really doesn't matter! There is no loss of power transmission, no skipping, no rattling when backpedalling after a shift. Just a very slightly different gear. And the shift forces are so much lower than with derailleurs. All of that means grip shift sucks on "old" drivetrains, but none of that applies to the pinion. I understand it's very difficult to convey the ease of shifting by words. It's even not that evident when you test ride a gearbox bike. But after 2000 miles, going back onto a traditional bike, I really had to re-learn how to shift "properly" - not when standing, not when coasting, repeatedly hammer on a heavy thumb shifter before going into a climb... This is when you realize what a crutch derailleurs are.

You feel it. And then you get used to it. Think of it like an 2.3 Enduro vs. 2.5 DH tire. Getting used to the shifter takes a bit longer, but it is much harder to go back to a derailleur afterwards.

@hamncheez: i don't feel too much drag with my pinion. Yes, it is there, but it's not that bad. The upside is a bulletproof shifting system with huge range AND fine spacing. The real problem with the pinion box is that it's overbuilt - coarse teeth and heavy duty gears make for high weight and a slightly "chunky" pedal feel. It feels sort of like pedaling on a 13t cog with a cassette, nowhere near as bad as the 10t SRAM uses to get a better spread number. Other than that, I HATE getting back on my MTB with traditional shifting after riding pinion. Shifting while coasting or stationary is so convenient, and the fine spacing is just awesome. And the shifter has a very rewarding feedback when you bang through gears, absolutely no delay and it NEVER misses a beat.

I used to think alike. But I commute on a pinion bike since half a year now, grip shift is superior. Super fast shifting through the finely spaced gears... Going back to a derailleur is like going back two decades in time.

Review: 1 Year on Cane Creek's Ultra-Light Titanium eeWings Crankset

Interview: Aaron Gwin on His Break With YT & Becoming a Team Owner
I don't think we will hear much YT in thid regard - which is fine. After all, it's just business - just like Gwin is handling his side of things. Maybe Gwin was just asking too much, maybe they were not confident he would offer them enough cvalue for that money... Whatever it is, "it's just business". For all involved.

Exploring the Relationship Between Handlebar vs Stem Length
@dirt-klaud: You didn't get the point, or at least didn't understand me: Fork offset is not defined by wheel size and head tube angle, but dictated by it. Meaning, in order to get a proper figure for trail, you need a certain fork offset - depending on wheel size and headtube angle. Fact is, fork offset is creating a force due to a different mechanism than handlebar offset, so it is not correct to try and correlate these two. The proper approach is to evaluate handlebar offset in isolation from fork offset and trail. Rather, what has a more significant impact is reach. With a higher reach, you will need a lower handlebar offset, otherwise the bike will be incredibly difficult to steer - even with a low trail figure. And if you don't have any handlebar offset, it will be difficult to keep the bike straight, even with a extremely long trail figure. The point is that handlebar offset always creates a centering force (torque, actually) on the steering, irrespective of the leaning angle of the bike. Trail, in contrast, creates a force that wants to turn the bike upright with the relation to the ground. Which is a huge difference once the ground is not flat anymore: If you're riding an off-camber section, trail will cause the bike to steer uphill. Handlebar offset will keep the handlebar straight, greatly inceasing control in this scenario. It also increases stability under hard braking; here, the trail figure decreases dramatically (due to the compression of the fork and concurrent lifting of the rear suspension, the headtube angle gets a lot steeper). Simultaneously, the deceleration puts a lot of pressure on the handlebar - which in turn keeps the bike going straight due to handlebar offset. The impact of wheel inertia is tiny in comparison - otherwise, stunts like whips or tabletops wouldn't be possible.
