Saw this in the commuter forum earlier and quite like the sound of it. I understand Shimano are giving a provisional release as sometime in September.
As my Pugsley build has been shelved for the time being, I'm rather looking forward to this.Stav83 wrote:Even the thought of the costs involved are scaring me... :shock:
Certainly cheaper than going Rohloff I'd imagine. Can't see it being that much more than the existing Alfine.0 -
I thought it was going to be the new SRAM ''XX'' groupset on one of your bikes. Mildly dissappointed, but the more I think about it, internal hub gears are absoutely the way forward.
No delicate deraileurs, twisted up chains, mud issues, and better ground clearance.
Plus, you can fit a beasty, last-forever chain. Or a belt drive, or something even more interesting!Boo-yah mofo

I'd love a Rohloff/Alfine + Hammer + Beltdrive system, it's just sooooo much work to get them fitted onto existing bikes though (unless you have a bike with elevated chainstays).0

I bet that sounds like a cement mixer in some gears - and probably about as efficient.0

I was under the impression Alfines were fairly quiet. That not the case? (never ridden one)0 -

Being an Alfine owner for 18 months years I can say that they are pretty damm quiet and very reliable. Obviously I can only talk of the 8sp version, but mine is smooth, quiet, and has never missed a gear change. Definitely makes sense for mountain biking The number of rear mechs and hangers I've been through is ridiculous, though Shadow technology has reduced that somewhat.
As an aside, my Alfine hub has been sat in the garage unused for 6 mths (I converted my Cannondale Badboy into a fixed gear job for winter training.) If anyone wants to make me an offer for a perfectly working hub, shifter and all parts to make it work, please do. The hub is disc compatible and comes with the 6 hole adapter. (I've also got the complete disc brake avail. separately if needed.) It's only been used on the road (bar one summer cyclocross race) and is as smooth as the day it arrived. And it's in black, rather than the cheap looking silver.0 -
I think they are going to be useful for MTBs - gives people the choice of derailers, or hub gears. Both have their pros and cons, so the consumer can pick what suits them best.
I imagine the 11 will be nosier, especially if the ratios are widened: just have to ait and see!0 -
Ok - I want the XX 11 speed cassette bastardized onto a Rohloff 14 speed hub gear, with 3 sprokets on a Shulmph 2 speed crank....supersonic wrote:I think they are going to be useful for MTBs - gives people the choice of derailers, or hub gears.

Theoretically 924 gear ratios.... :shock: Boo-yah mofo

Or how about the V Boxx 16 speed gear box?!0

or somebody develop CVT for the bike...0

there is a guy on STW who has an alfine and hammerschmit combo (refered to as Frankenbike) but has commented that in 'overdrive' it is Incredibly draggy so i think the alfine was coming off??
certainly makes sence though, the less delicate parts on the system the better but at a penalty of weight??
Belt drive would Rock! bit of a bummer if you break or stretch one though!!Timmo.

I was waiting for someone to mention the weight penalty on the Alfine hubs. I think in time they will resolve the weight issues. How often, if ever do these things require periodical maintenance, if at all?0
-
I had a genius idea, crack open an alfine and move the pawls so it freewheels in the other direction. Mount your cranks the wrong way round.
Replace bb spacers with metal h to hold hub there. Fit a c-lock - 6bolt adaptop and a fixed 6-bolt sprocket to the other side. Run a fixed+6-bolt rear hub and voila, gearbox bike!0 -
The Alfine 11 hub is reported to weight 1600g0

1600g! :shock: :shock: :shock:

XT hub, cassette and mech is, for comparison... about 850g.0
-
That is a bit of a fat bastid.0
-
so twice the weight and prolly a smidge more than twice the price????
i can see the benefits for such items but the weight penalty just doesnt suit it IMO,
same as the Hammerschit, great system but again twice the weight of std set up, if the weight could be reduced without the price rocketing for Ti internals! then i think they'll catch on a lot quicker!!Timmo.

well if xtr, xt and slx go ten speed next year, then why would you want 11 speed??? thats just silly plus its a darn sight heavier too. 0

Surely you would also need less chain and shorter spokes which would weigh less? ... Every little helps and all that 0 -
That is true! Add another 50g!0
-
I have to say, Imo the only application I can see for the 11sp Alfine hub at the moment (considering the 8sp one does a perfectly good job, albeit with some large gaps), is going to be the fat bikes, where the extra durability afforded by internals will *sometimes* outweigh such a massive weight penalty (weight is generally not so much of an issue on something running 4" tyres).0
-
Got to remember that with this new one you'll be swapping it for two mechs, one shifter and a good length of chain so the increase is likely to be 3-400g0

dunno about the 11 sp but the 8sp is quiet as the grave ... but in a good way. None of teh funny noises like you get with some gears on a rolly
transmission efficiency probably isn't as good as a nice clean deurallier set up but it's certainly not bad (I have 5,000 road km on mine so far) and apparently can be improved by cleaning out teh factory applied grease and replacing with oil.

Beer in moderation ... is a waste of beer
If riding an XC race bike is like touching the trail,
then riding a rigid singlespeed is like licking it
... or being punched by it, depending on the day0 -
thinking about how many gears you could get on a bike, didnt me and SS have a bit of a big gear battle a while back, im sure one of came up with over 100000 gears....
here goes..

the thing is, im sure we got better than that... what have i forgoten?I like bikes and stuff0
