Re: Why the Rohloff Speedhub is (secretly) inferior

Nothing is perfect and nothing lasts for ever; when it comes to bike parts it is arguably a question of choosing your poison. I don't know how you can maintain the fiction of '100% reliablity in A11' when you have had hubshells break. It doesn't make sense. That's not what I'm saying, Brucey. What ...

Re: Why the Rohloff Speedhub is (secretly) inferior

Alfine 11s hubs which see hard service seem to have hubshells which fail near the disc mount cheers I have come across this issue, Brucey, as you well know, I reported it in the thread (did manage to weld it back up and that hub is operational, just for V-brake only). That was a first type A11 SGS7...

Re: Why the Rohloff Speedhub is (secretly) inferior

For a hub that was never opened up in more than 10 years, trust me, the cog will not only be stuck but effectively welded shut (cog is steel, driver is aluminium, the cog is screwed in by way of pedalling, that's a recipe for disaster that became so apparent they had to put out that flimsy adapter w...

Re: Why the Rohloff Speedhub is (secretly) inferior

Dear Brucey, Thanks for taking the time. As always, your points are valid and there is no doubt that, apparently, the Speedhub is the "better" hub but my point is that is due to a sole design difference between the two: indexing. If Shimano take the time to refine their one cable approace ...

Why the Rohloff Speedhub is (secretly) inferior

I have been servicing Shimano IGHs for years and using only Alfine Inter-11 on all my bikes. I'm very familiar with the inner workings and the materials used in these hubs. This year, out of curiosity, I got my hands on a Rohloff of my own and started tearing it down. First major issue with these hu...

Re: Shimano Alfine 11 - Longer term reliability

it makes a difference if it is 32 or 36 drilled cheers Cheers Brucey! Indeed, it was laced onto a stamped 36h 559-19 Ryde Zac Pro rim. I haven't tried a 32h but issues could appear as the angles would increase. as reading somewhere the more holes a rim has the more crosses it can take, like for ins...

Re: Shimano Alfine 11 - Longer term reliability

I laced an A8 4-cross and it's fine, the spoke heads don't touch the spokes. I used Sapim 2.0mm straight spokes. They way it looks, more likely that with more heavy-duty 2.3mm spokes the heads would touch the spokes but other than that, it's doable.

Re: Shimano Alfine 11 - Longer term reliability

You can lace it four cross but a) in 32h especially, the spoke heads may foul adjacent spokes b) the rim may or may not allow the nipples to articulate fully; choose your rim with care Small rims invite bigger nipple angles and are less easy to build this way. cheers Thank you much, dear Brucey, fo...

Re: Shimano Alfine 11 - Longer term reliability

Is it possible to lace the Alfine-11 in 4-cross or is the hubshel too big to allow for such extreme spoke lenghts?

Re: Rohloff Oil - alternative

The thing that worries me is the probability of the rohloff oil being inferior to what one can find in the market. I mean, the officially recommended oil change intervals are ludicrously short considering the gearbox does not experience the extreme temperatures and the torque levels an automobile do...

Re: alfine 11 hub shell replacment?

No the welding material simply interfered with the hub How exactly it interfere? When I got mine welded last week, some material overspill on the centerlock splines and a bit of bubbling was on the opposite, on the inside, but managed to file it all back to a workable shape. Only thing now is to we...

Re: alfine 11 hub shell replacment?

The guy that made the welding had the welding interfere with the hub itself, it's not like i had much hope for it. The newer version has a small difference in parts , but i'm not sure about the shell itself Did the hubshell warp or something? The newer version uses the exact same hubshell, I'm not ...

Re: alfine 11 hub shell replacment?

oh i have up on that a loooong time ago, but i've discovered they made a newer model more suitable for e-bikes, would be interesting to see how it holds out.. Did you give up on that hubshell? What happened to it, didn't the weld hold? Wasn't it usable like that? Please let me know more about your ...

Re: Shimano Alfine 11 - Longer term reliability

I appreciate it, Brucey, but it's not a matter of replacing the hubshell. I'm running A11 transmissions on my three bikes and this is part of the longer term reliability ;-) testing of these units. The challenge is to have them run for as long as possible without recurring to new parts, if the parts...
