I say if you can dream it build it. There may be less expensive ways to do it as others have pointed out, most notably the Alfine 11 speed IGH, but part of the fun of bikes and gear is coming up with off the wall applications. I recently converted my Handsome Devil from a Sugino Triple

Back when the mystery bike was still a mystery, Grant had thrown out a clue, which I had wrongly guessed as meaning the inclusion of a Hammerschmidt 2-speed derailleur-less crankset. Well I wonder now whether it might not be a bad experiment to try out the FSA Metropolis Patterson crank on

I'm really kind of intrigued by the 1x11. From what I've read, it's a whole system — special front crankset with the teeth shaped so that no chain catcher is required, and the RD is new as well, moving differently than typical derailers. This link has some details:

Interesting and doubtless silly-expensive. I'd like to know the proposed price of those one-piece cassettes. The idea is good, but I wish they'd put that RD into cheaper, wider-range (500%+) and more efficient internal geared hubs instead of ever more complex and expensive -- and finicky? Don't

I believe the cassettes are around $425, and they require a special hub. You're buying a system, really. It's geared for terrain riding, so a different market than the Roloff. Lighter, too, I'd imagine. On Thursday, September 27, 2012 10:00:02 PM UTC-4, Patrick Moore wrote: Interesting and

Maybe this 1 x 11 equipment will start out at the top of the line then trickle down if it sticks. $425 for a cassette is aimed at some extremely rich riders. Is 11 speed chain even narrower thatn 10 speed? Wonder how friction would work on 11 speed off-road? When you think about 10 teeth to

At least for the new model with its horizontal drops, you can use an IGH. And the Rohloff hub gives more than 500% range, better than any cassette, I would guess. Very expensive of course, but the quality and durability match the price. And the Alfine 11 gives more than a 400% range; I've

Shifting gears while the bike is stopped and your feet are on the ground is a nice benefit. Really helps a lot in traffic. And a straight chain path with no rear derailleur to run through is nice as well. Additionally, as Doug mentioned, there is the gear range issue. Rohloff for sure and I

I'm pretty sure the combination of slack seat tube angle, super low BB, and long chainstays that angle noticeably upwards from the BB prevents the use of a normal FD on the Mystery Bike/HS/Bosco Rubbe. If you set the derailleur low enough to be effective, the cage will hit the chainstay
