The Alfine 8-speed hub gear features a Center Lock system for mounting a disc brake rotor. Furthermore, this 8-speed hub has a high driving efficiency by using needle bearings and a forged hub shell in an attractive design. Gear range is equal to the already proven Nexus 8-speed internal hub gears. The Alfine gear hub has a single sprocket and a chain tensioner will be available for use with vertical drop outs. The single speed sprocket has been provided with a chain guard.






its actually been out for a while but only OEM on bikes.
i can't seem to find if its any better than the red band hubs
that GT is using on there bike.

anyone else have any info or work at a shop that has one
on a 08 trek/rm/cdale?

So....is it too weak to take a DH beating, or is it decent enough to take a beating and matched to a Rolhoff's pricepoint?

in board it would be fine.

yeah, its like 400 so it would be way afordable vs gboxx/rohloff.

i hope to find one to ride on a city bike at the show to see how

far tehy have come.

So would typically fail in these things if applied to DH use? Would it be the hub body, flanges, etc. or would it be the internals? Just curious. I don't know much about them.

i've seen the axle snap, then internals just shatter when using a nexus hub as just a rear hub. for dh use. its not pretty

the guy's wheel slammed into his frame, breaking the swing arm.

I've been using one on my commuter for 6 months and I love it. So smooth and quiet. I'd love to see one mounted onboard a dh bike. It would be one of the only ways to get a trigger shifter on a gearbox bike. DO IT BCD!!

thats what i was thinking, people want a inexpensive, simple, trigger shifted DH frame.

i am riding one at the show end of the month to see how it feels.
mainly the shifter, can you take more that one gear at a time?

looks pretty cool. i have been out of the loop for a bit and missed
its debut. not that it was available then. but now it is.

i broke two axles. that is why i think gt mounts it on bearings
where the hub flanges are. to take some load off the axle. still
have to fix the axle to let the hub drive around it.

Just to clarify, you broke 2 axles on your frame mounted nexus bikes? I was hoping that in frame mounted applications it would be protected from the huge side loads a rear wheel feels. I'm suddenly a little depressed.

By the way, that Brodie Ocho doesn't actually have an alfine rear hub in the picture. They faked it to get the catalog shot. The real one has a larger cog (18 or 20 t ) with black plastic chainguides on either side.

The trigger is only one gear at a time. However, it more than makes up for it by being able to shift while coasting.

well mine was not exactly in the center of the main pivot so as
i went into my travel it tightened the chain over loading the axle.

it was my second bike ever, didn't know much. i think i can get it to
hold fine now with being more accurate.

bcd- could you make a frame that would accept almost any geared hub such as rohloff or one of these alfine hubs, (i want the rohloff 14sp)

I am more interested in a more fr/not too mini dh type bike than pure dh, and I pedal up hill most of the time, so a typical 2 chainring and mountain cassette gear range is a must, as is a seat tube that allows full up and down movement. the new corsair maelstrom looks pretty sweet(geometry and travel are what I have been waiting for), but I would rather have a gearbox bike. I can deal with the grip shifter until someone actually makes a trigger for a rohloff.

I like the Lahar except it is too much of a race bike. too long and slack. too much travel. pivot is higher than I need.

this winter I would like to get another bike/frame, currently I have a bottle rockett which is great but not enough travel.

anyways just throwin' my idea out there to see what you think.

well you know me. i make race bikes.
the shimano is smaller OD than the rohloff so it can't retro fit.

what about a nikollie sp?

Internal hubs require cocentric pivot placement(chain growth) which once calculated with the chain line doesnt give very good anti-squat.
its a compromise for center weight distribution and sprung-to-unsprung a lot of people don't mind taking.

It looks damn near like the exact same thing as the saint shifter. If that is the case you can shift multiple gears with the thumb and one at a time with the index finger. The paddle for the index finger is very tiny and kind of a pain in the ass to hit in a hurry. You may want to experiment with making an extension for it to use on a race bike.

I wonder if the hub is a low normal or a high normal set up.

aaron mentioned developing an 'all mountain' variation of the m9 with different links, no floater, dhxa, etc. sounds interesting. may be a ways out though.

having ridden the rohloff gripshifter for most of a season, i can't really say it's something that bothers me. (though i'd most likely pick up a trigger if it ever comes out).

It's low normal / rapid rise. too bad. With some of my bikes using sram shifters, I always shift the wrong way a few times on my commuter.

the terms high normal and rapid rise are really only applicable to cassette-type drivetrains, don't you think?
planetary hubs don't really shift easier one direction or another..

nope. and it's slow.

A bunch of people talk about using a thumb paddle for each side of the handlebar, but how would you route the cabling on that?

I think if you went to the trouble and cost of custom designing a bike around one of these hubs you'd realize you'd rather ride a derailer and cassette.

As far as using it as a hub:
I'm a huge fan of planetary-geared hubs, but they still belong on commuter bikes. That's all the alfine is made for. and the disc brake mounts are really meant for bikes in this market:


not mtn biking.
I mean, what's that hub going to do when it heats up from the brake mount anyway? It'll cook the grease.
