Ghost H AMR X

The H AMR X also plays on the idea of being an adventure bike, but with 140mm of suspension travel front and rear, some people may not be too keen on bikepacking with this rig. However, it does have some quality componentry, with a RockShox Pike RCT3 Solo Air fork up front, a Cane Creek DB Inline Coil in the rear, SRAM Guide Brakes, 2.8″ Schwalbe plus tires, an SP Hub Dynamo, Race Face Arc 40 wheels, and a RockShox Reverb Stealth dropper post.

Unfortunately, it has the same poor chain tensioner design as the Roket X.

With an aluminum frame, claimed weight is just over 36 pounds… and that’s without bags.

MSRP: 6,000 Euros, or $6,682

Back in the days of 3x drivetrains with their less than reliable shifting on the front chainrings, a gearbox drivetrain seemed like a good idea. Now, with modern wide-range 1x drivetrains like the Sram Eagle, gearbox drivetrains are solving a problem I just don't have anymore. The fact that they weigh more, cost more, and are likely to be difficult to repair makes them even less favorable.

Can only imagine how much more these systems cost relative to chain / derailleur types.

I agree with stumpyfsr. I like the fact that the drivetrain weight will be transferred to the b/b and help with the center of gravity. It makes the more whippy, so to speak. However, what do these thing run for? I'll bet they ain't cheap. So the question is: are they really worth the extra weight? Are they actually easier and more maintenance free than a regular shifter set-up? What happens if it breaks? Do bike shops have the tools needed to fix one of these gearboxes? Just some questions to consider. I'm sticking with a normal set-up until internal gearboxes become more common. Then we'll see if they are worth it....

If and when they get the balance right - low enough weight, reasonable cost, etc, then these will become real game-changers. The advantages for the average rider are not there yet. But in certain applications, they might make sense. From my understanding, the units are fully sealed, and there's little to no maintenance required for thousands of miles. So for someone doing a long bike-packing trip one of these gearboxes might make sense. If you price out the cost of an Eagle drivetrain, along with all the chains and cassettes you'll need over the course of a few years, the additional upfront cost of a gearbox might start to seem less onerous.

Like the idea, and maybe on an adventure bike, DH, or even an enduro rig the weight penalty is acceptable. Any idea what the weight penalty actually is?

Looks like a good idea to me. I think it's (gearbox) similar to Alfine internal hub but with benefit of weight being transferred from rear wheel to the center of the bike.
