There are a few variants, you need a special one for the alfine. The sprockets slips onto the hub. It should come with a C ring that holds it in place. Having said that I have stripped the sprocket where it mates with the hub, and am waiting for a reply and replacement from distributor.

I have an 11 speed Alfine in hand and the Gates Carbon Drive rear sprocket but I do not see how they mate or connect? I suspect I am mising an adapter of sorts, do you have a art number or reference to where you bought the connecting part? I bough the rear cog and belt from Gates but it did not arrive with any fixings?

No, 135 mm spacing is required.
With some tinkering (grinding off the locknuts to a smaller thickness) you may take it down to say 132 mm judging from the cut-out model at the Eurobike, but that’s it: The left bearing is very far left under the CenterLock stubbin’.
If someone needs even lower OLD on a standard bicycle, any Shimano Nexus hub (preferably Inter-8 Premium red stripe) for RollerBrake without the Roller brake is the best bet: 122 mm without the spacers, using thin locknuts a few millimetres less.
The Sturmey-Archer X-RF8 (W) is narrower still, but only suited for small-wheeled bicycles, direct gear being first (!) gear.

Does anyone know if/when a manufacturer will offer a complete bike with this hub? I’ve looked, but so far have not seen anything at all. Thanx.

Excellent piece of engineering, as always from Shimano. The price is high now but that will pass, the performance wont. Shimano Alfine 11 is something I would give myself for Christmas.

Sorry, I correct new “developpements” with Alfine 11 speed is 1.7 to 6.9 meters !
Before the Nexus 7 speed I had a Sturmer Archer 5 speed, akward shifting, two cables and setting difficult. I think hub gears are not recommended for mountain bikes and heavy brutal service. Moreover repair and on site urgent interventions are far easier with classic dérailleur. I have both system on several bikes.

Since 1999 I have a Nexus 7 speed on a light sport bike with 700C 23 wheels, 42 front/21 sprocket gears which gives 2.65 to 6.50 meters developpement (sorry I am french and metric minded). Nota, I withdraw the internal brake crown, using normal on rim more efficient brakes.
Presently a Paris french cycle shop prepare a new similar wheel with Alfine 11 speed.
I will use a 32/21 gear which gives 1.7 to 8.6 meters. First gear is very low but as first to second gap is a bit high I intend to start practical extreme rides with second gear 2.2 meters.With previous 42/21 gear , it should have been 9 meters, which means 48 kmh (sorry not miles) at 90 rev/mn, too fast for a 70 years old however fit veteran RGDS
