Shimano Alfine 11 Speed Hub – SG-S700

The Shimano Alfine 11 speed is scheduled to be available in the Fall of 2010.

It’s an upgrade to the Alfine 8 speed hub and ups the gear ratio from 307% to 409%.

Like the Alfine 8, it incorporates the Shimano disc brake with the hub.

Alfine 11 Specs

  • Weight: ~1600 grams

Bikes Built With Alfine 11

  • Mixer 11 – an urban/commuter bike from Charge Bikes
  • Duster 11 – a cross-country/cyclo-cross bike also from Charge Bikes

Here’s an early video about the Alfine 11 narrrated by a Shimano employee:

If you’re looking to buy the Alfine 11, you can find it at Amazon here.

    quero comprar um alfine 11speed.

  2. Frank from Germany

    Puedes comprar la Alfine 700 (11 Cambios) en Alemania. Pero todavio cuestan muchos Euros. Entre 350 y 400 Euros.

    Mejor esperar un poco. Los precios caerán igual que con la Alfine 500 y 501.

    has anyone tried the shifter for this hub on the older alfine8? i want to know if the shifters pull the same amount of cable for each gear?

    I have found a picture with the specifivations of the alfine 11 …

    I have a question. Does anyone know whether or not the oil actually makes its way onto the main load bearings? Or do the cones stop it before it can actually gets there…?

    Hi. Does alfine 11 uses the same non-turn washers of alfine/nexus 8? it´s not clear in the docs nor on the online shops pages. I´m looking for non-turn washers for a Surly Karate Monkey frame (horizontal dropouts), and it seems that i need the 6R/6L, is this correct?

    • Anonymous

      Yes,
      and for horizontal 0° drop outs are good:
      Y33M39600/610 silver/white

      and if using a chaincase (& 0°) recommended
      Y33Z20500/510 Yellow/brown

      And sometimes(here in Germany) it is cheaper to buy them completly with the interface instead of the two single washers

      • Hi,

        Thanks for the info. I got the silver/white ones, and it seems good. But you got me thinking… what is the “chaincase”?

  7. Anonymous

    I suppose it is like Hebie`s chainglider (Chainprotection)

  8. New roadie build with alfine 11 and belt drive.
    I’ve started making a new road bike. I have an alfine 11 hub, ally fixie frame and carbon forks, a versa VRS11 brake lever and am making it belt drive.
    The belt drive is a gates carbondrive belt with DIY stainless laser cut sprockets made on the schlumpf pattern. This means of course that my old bike (alfine 8) will appear on ebay fairly soon….

    If the picture works I’ll put more pulley pics on as I progress.

    • picture didn’t work – how do we put pictures on here?

      • eliotk

        I think that setting up the image tag like this should work:

        [img src=""]

      • eliotk

        Actually Bob you can just use regular HTML code for embedding images and that should work. Can’t really show you here because it will disappear but I’m guessing you know what that means.

        Also, sweet setup! I was able to see the URL to the image in the admin area.

    • Plenty of progress (& money spent). I’ve done 3 trial sprockets & the proper design is now at the laser cutters. The frame has a bolted joint in the rear triangle to let the drive belt in & I bought a brooks B17 saddle for it in black. Here are a couple of pictures – one is photomicrograph of the gates belt which I used to determine sprocket geometry, the other is the sprocket design to go on the alfine11 hub.

    • Here’s an ilfine pulley lamination, fresh from the laser cutters

      here are all the parts to make “chainring” and “rear sprocket”

      just needs flash scraping off & screwing together….

    • pulleys done (the ally crank pulley took 3 hours to fettle – the laser left a lot of flash) & installed; frame split at the RHS dropout seatstay

      all feels good but not ridden yet.

    • Bike all together now, rides great (everything behaving exactly as it ought) Versa ‘STI’ lever and alfine11 seem to make an excellent partnership. The hub puts up some resistance to rolling or pedalling backwards but otherwise seems superb. When I get a nice day I’ll post a photo of the finished bike.
      To be honest I’ve only ridden 400yards…. it was raining :^(

    • Anonymous

      OK the bike is together and I’ve had a couple of short rides. I must say that so far, so good; the bike delivers all I had hoped. The Alfine 11 + versa shifter work beautifully and the belt transmission delivers a magic carpet ride. If my home-made timing pulleys keep this up it will be a great success – we’ll see over the next few thousand miles if belt wear is acceptable ;^)

  9. try agin then…

  10. struck out with the pictures…

    • I have been using the bike for 2 years now & probably covered 3000miles on it. Frankly it’s been fansastic. The Alfine 11 hub has not missed a beat (or a gear). I had to remake the crank chainring recently, the Ally original collapsed with fatigue failure(s) & I replaced it with a better designed stainless steel version. That aside, I have done absolutely zero maintenance this year, just pumped up the tyres twice & twiddled with one of the brake barrel adjusters. That’s what I wanted from the bike, consistent great performance at the price of zero TLC! Here’s a picture of the new front pulley

      I’ll probably build up a new bike over the winter – I fancy a retro steel frame, drum brakes & a cheaper belt drive system on the next one…. but this bike has been a good ‘un

  11. Simon

    I have a 2011 Charge Duster 11 (only for the last 3 weeks) and have been on a few rides , so i guess about 150 miles covered. I am encountering a few worrying noises. Klunking under power and some gears (6 & 11 especially) often work at a lower ratio than they should.

    Whilst it is not easy to guess what is wrong, I have adjusted the cabling to what I think is optimal, but there is still problem in these few gears, and i am worried by the klunking as i felt that this would be impossible with the oil bath?

    returning the bike is an option but a last resort as it is wiggle and there warranty team are not quite up to scratch!

    any clues?

    • make sure red dots line up on hub. a video on youtube shows how its done on an Alfine 8. You’ll get the idea, just gets your cable adjustment correct. ride it around on the streets before heading into the rough. plus the hub is designed to change when you stop pedalling. halt your pedal stroke particularly when changing into an easier gear, it only needs a moment.

      • actually, they are yellow marks and when you turn the bike upside down, will be obvious as they then face upward. they are supposed to line up in 6th gear. count down from 11 or up from 1 since you’ll not see the indicator with the bike upside down. The indicator doesn’t exactly line up with the numbers anyway.

  12. Simon

    Tim, I have ridden it a little more and building confidence in it, but, no matter how much fine tuning, it always seems to have 1 or 2 gears that play up (if 6 is working 11 may not, if 6 and 11 work, 4 doesn’t) but i guess it may still be bedding in. I have sped up the cadence a little. This may help to; identiify if it is a bedding in issue, and, if i am slowing down enough for changes.

    Will report back with any observations.

    • Anonymous

      Hi Simon, It could be a bedding in issue, try clicking up and down through your full range of gears, whilst standing still, it could be something as simple as the gear cable is to tight or even the chain.

      I’ve just had my bike serviced, I have an Alfine 8 fitted to a full sus MTB. The gears were working fine before the bike went into service, after the service when riding up hill some gears seamed to slip when stomping hard on the pedals.

      I was told they had removed 2 links from my chain durring the service. After clicking through my full gear range 5 or 6 time the gears stoped slipping and worked fine.

      Good luck, Dean.

      • Simon

        The setup I have is a steel hard tail with a alfine 11 speed shifter, 11 speed hub and fully enclosed cable run. The cable run or shifter is where i feel the problems now lie. I have to adjust this every ride, perhaps it will settle down, and tuning in is not too arduous. I will check back if i get more info.

  13. Zen

    Just bought a new Specialized Source 11 (Alfine 11 speed belt drive bike.) I have slippage in gear 7 and a dead spot around gear 10 (crank just spins wildly.) Will adjusting the cable solve this problem?

    • Simon

      Zen, I have had the same issues, but they do resolve themselves. You do need to keep tuning, it gets better as it beds in. use the adjuster on the shifter to line up the 2 yellow marks.

      • Zen

        Simon, this is now Nov 1 and I still have slippage around gear 6 and between 10 and 11. I checked the yellow marks and they are aligned. How long does it take to “bed in?”

  14. Matt

    Hi I’m a newbie looking to purchase a Alfine 11. The only issues I have is the price of the service kit (excluding the oil)
    Two syringes and some clear tubing for £45 +. The only peace of kit I would need is the bleed nipple that fits the hub. Has anyone done this or looked into and if so could you point me to website were I can buy just the bleed nipple. Thanks Matthew

  15. Steve Weeks

    I’m riding a Tern Eclipse S11i with an Alfine 11. It is a very nice hub. Shifting is smooth and operation is utterly silent. Actually, the entire bike is silent. I am really impressed with the hub, though. I have tried standing on hills and it does not slip at all. There’s more range than my Nexus 8 hub; I rarely get into the top 2 or 3 gears.
    Steve

  16. Has anyone disassembled an Alfine 11-speed and can send me tooth counts for the internal gears? This is the one important hub for which I don’t have fractional ratios in my charts of gear ratios at http://john-s-allen.com/gears/hubratios.htm. You may respond as a follow-up comment here or by e-mail to the feedback address at sheldonbrown.com — thanks!

  17. Christian Lyra

    Hi. I need a advice about cranksets. How (or which one) to get the recommended chainline of 42mm on a Surly Karate Monkey frame which has a 73mm BB Shell? I would like a 34T ring, and strong enough for XC. Thanks!!

  18. See http://sheldonbrown.com/chainline.html. There are many ways to achieve the required chainline when there is only a single chainwheel. A Phil Wood bottom bracket offers adjustability, as well, and is available in a version for a 73 mm BB shell.

  19. Is it 6th gear or 4th you tune the yellow dots in?

  20. 6th gear. You are supposed to approach 6th from the higher gears, not the lower ones. This is going from lower cable tension (gear 11) to higher tension. See this (from this site): http://techdocs.shimano.com/media/techdocs/content/cycle/SI/SI_37R0A/SI-37R0A-001-ENG_v1_m56577569830713437.pdf

    Need to buy the maintenance kit for the Shimano Alfine 11 speed – have been waiting more than 6 weeks. Does anyone know where I can purchase the following parts either Australia, UK, USA, etc. –

    1 YI3098481 SG-S700 Oil 50ml (seen on eBay from Estonia)
    2. YI3098025 – Tube set and bleed nipple

    Thanks, camijen

    • Steve Weeks

      I finally bought the kit (oil plus tube & nipple) from Estonia. It arrived in a timely fashion, and I am ready for the oil change in another hundred miles or so. See my note here: http://www.ternbicycles.com/forum/verge-s11i-report?page=1#comment-4960
      I’m goinf to have an NMR comparison done of the (very expensive) Alfine oil versus automatic transmission oil. I’ll post a note here when I have the results.
      Steve

      • Steve Weeks

        My bike reached the 500 mile mark, so I changed the oil. I noticed that the procedure was supposed to be done at 500 *KILOMETERS*, so I’m a couple hundred miles late. Oh, well.
        The procedure was quite simple. Instructions came with the kit (see http://techdocs.shimano.com/media/techdocs/content/cycle/SI/Tools/SI_7080A/SI-7080A-002-ENG_v1_m56577569830746517.pdf

        I’ve posted a bunch of images on the Tern site: http://www.ternbicycles.com/forum/verge-s11i-report?page=1#comment-5842

        There was a fair amount of metallic dust in the old oil.
        Next oil change in 1,000 KM (~600 miles).

        If anyone understands how to read a magnetic resonance scan of lubricants, have a look at the post here: http://www.ternbicycles.com/forum/verge-s11i-report?page=1#comment-7207
        I saved a half ml of the Shimano Alfine oil and a friend of mine ran scans of it and a sample of ATF. I’m sure there are other parameters that are relevant (viscosity, for one; ATF is somewhat less viscous) but the scans look fairly similar.
        It is hard to imagine any reason that a lubricant that serves and survives in a car transmission would not be adequate for a bicycle.
        Any opinions?
        Steve

      • David A

        My sg-700, with about 3000km on it, had a couple of ‘haemorrhages’ – overnight, deposited 5+ ml of oil under the bike. That’s a lot when you have only 25ml to start with! So lower viscosity ATF might worsen the problem. I added silicone around the axle as the OEM seal isn’t that great, and the hub hasn’t had a serious leak since the last oil change, tho’ it does ‘weep’ a bit.
        All that said, given the price difference between ATF and Shimano oil, I plan to switch lubricant at the next service. Please post any further investigations – yours is the first scientific appraisal I’ve seen. Regards

  22. Steve Weeks

    David, I have been thinking about the same things. Though I have not measured the viscosity of the “Alfine Oil”, my distinct impression was that it is higher than that of ATF. That would make it seem more likely to leak through small gaps in seals, etc. I’m thinking of using 80W-90 hypoid gear oil, which is more viscous. Still looking for alternatives, though.
    Cheers,
    Steve

    • David

      Steve, I think your 80W guesstimate sounds good – could your kind buddy add viscosity testing to his resonance scan, so we can be more certain? it’s a (relatively) low-stress mechanical environment, so I don’t think fancy ‘stickiness’ additives will make that much difference…

      jsallen: I don’t run my hub much over 100 degrees Celsius, so a single-viscosity oil might suffice… :-)

  23. Phil Wood oil is about the same viscosity as hypoid gear oil, but it is sticky. Aaron Goss uses it in his hub rebuilds. I’ve used it in Sturmey-Archer hubs, sometimes thinning it with lighter oil in winter. In a hub that is full to the brim with oil, high viscosity could be an issue by preventing pawls from seating, and especially in winter. I wonder whether the Shimano oil is multi-viscosity. Motor oil is multi-viscosity, but it is thinner and intended to be constantly renewed under pressure. Industry info on gear oils: http://www.le-international.com/uploads/documents/079_Gear%20Oils.pdf

  24. And note that the indsutry info describes multi-mivcosity high-viscosity oils — probalby available at the nearest auto-parts store.

  25. Cummings Transmissions TRANSYND ATF is great for internal hub gears. Available at truck shops that service over the road, Allison transmissions or perhaps from your local NAPA auto parts.

  26. Haward Enginator

    Oops I meant Allison Transmissions… Not Cummings.

    Try Allison Transynd

  27. Steve Weeks

    I’ve got a few weeks and about 60 or more miles on my Alfine 11 since I changed the oil to “Royal Purple” gear oil, 75W-140. This has about the same viscosity as the green Shimano oil, but only costs about $24 a quart. It’s a synthetic, for whatever that’s worth. The Royal Purple web site says that this oil does not contain sulphur or phosphorus compounds which can corrode “yellow metals” (brass, bronze, copper). I do not know if the Alfine hubs contain these metals, or if they would corrode at the low temperatures the hubs operate at. It seemed like a reasonable thing to avoid a risk.

    What I have noticed is that the hub’s performance is no different than before, as far as noise and perceived energy loss go. My *impression* is that the hub shifts better. I usually have a missed shift once a week or two, and since the oil change the hub hasn’t missed once. Of course, this isn’t anything more than my impression, and could have resulted from a change with new Shimano oil too… a bunch of fine metal particles were flushed out during the process.

    But, the oil seems at least as good as the OEM stuff, and is much cheaper. It is also possible that the heavier weight of this oil will make it less likely to leak through the seals than automatic transmission fluid.

    So the experiment continues! :-)
    Steve

    • David

      Thanks for leaping in to the unknown, Steve :-) I agree about the metal dust at each oil change, and wondered whether a mild solvent flush (pull off the end cap, run the waste out the bleed hole) might assist the process…

    • Krirk

      Would like to hear a catch up how did it go
