Alfine 8 adjustment
1 Attachment(s)
Hi guys,
I've recently purchased a customized bike from Temple Cycles (Classic Hybrid ? Temple Cycles - Classic Stylish Steel bikes UK) featuring an Alfine 8. Unfortunately, I've had some bad luck with it. To cut a long story short, the brand new Alfine 8 isn't shifting gears properly. Basically, anything beyond the 5th gear doesn't work at all and the first 5 gears don't work very smoothly. I've checked the alignment of the yellow dots (see attached photo) and, unsurprisingly, they're off. However, tightening or loosening the gear change cable by turning the adjustment thingie on the shifter didn't seem to do anything. I've tried both extreme adjustments (as loose as possible and as tight as possible) and neither seemed to move the position of the yellow mark. Since this isn't the only issue I've had with the bike so far, I'm a little irritated. If you couldn't already tell, I'm pretty much a complete newbie. I'd really appreciate your help! Thanks in advance! Cheers, Michael |
What does the Owner's Manual say? it should include the adjustments to synchronize the shifter and the Shiftee, the hub.
may the guessing of others commence.. cable dragging binding in the housing is my guess. |
Could be defective or improperly adjusted/assembled. Have you contacted Temple Cycles? Or brought it by the shop where you purchased the bike?
|
Are you saying that when you adjust the barrel, the dots do not move? Or is the problem that no matter how the dots are aligned, the shifting is poor?
|
I can see the problem in your photo. The cable is not routed around the cassette joint properly.
|
it's easier to have a shop look at it for you. sounds like it's not setup correctly.

oh yea, I think this guy might have put on the dropout washers on wrong. the cable guide should be horizontal with respect to the chain stay, either pointing towards the crankset or away. yours look like it's pointing at a 45 deg angle, and the cable is routed along the top, when it should be routed around the bottom...

In addition to an incorrect cable routing, you are looking at the wrong points for the adjustment. The yellow dots are only there for installation. The yellow LINES above the yellow dots (closer to the chain) are what should be aligned. In your picture you can barely see the 2nd yellow line. In the 8 speed I THINK it's 4th gear that should make them aligned. The manual will tell you for sure.
http://www.koga-signature.com/docs/m...nce-manual.pdf This link has a "manual" of sorts that includes color pictures. And I was correct. In 4th gear the yellow LINES should be perfectly lined up. Also, make sure you're using the correct dropout locknuts for the specific angle of dropout for your bike. |
Thanks a ton for all your replies!
To give you some more back story: I can't have Temple help me (other than remotely) b/c I ordered the bike online. That's also the reason why the local shop refuses to provide any service b/c Temple doesn't have any dealers/partners in Germany and the shop says they can be held liable if they damage something. Anyway, I recently had to remove the rear wheel to install fenders and the possibility that I didn't put the lockouts back in the right angle is very real. To me, this angle seemed like the only possibility, and of course I was dumb enough not to take proper photos from all angles beforehand, but I assume the guys at Temple know what they're doing. So I'll definitely check the cable routing. Also, it's a 7000 series hub.

The coloured indexing washers generally only fit one way. If the cassette arm just wont go at a good angle, you probably have the wrong washer. can you even fit them both switched over? Never tried it.
The other thing that can go wrong is the position of the nut on the inner cable beyond the outer. Shimano specify the length in mm and you should stick to that |

-- Anyway, I had another look at it and I can't see how the cable should be routed any differently. The gear change cable is currently routed along the top tube, so it's at a 45°ish angle close to the hub. There's no way to have it at a 180° angle so long as it's routed along the top tube. I've taken another photo from a slightly different angle. Does that give any more info? I'm afraid I am pretty much at a loss as to what to do. As mentioned, I am a complete newbie, so I am very restricted in what I can do myself. http://bikeforums.net/attachment.php...hmentid=482379 Thanks again! Cheers, Michael EDIT: Sorry for the double attachments. My JPG compression service flipped the photo for whatever reason. The vertical photo shows the original angle. |

I am not entirely sure what you mean, however, I wasn't the one who installed the hub. I am only trying to adjust it. I would assume it's been installed correctly - but then again, everybody makes mistakes. -- Anyway, I had another look at it and I can't see how the cable should be routed any differently.

Cable routing along the top tube and pointing the cassette joint up the seat stay is an option on some builds, I've done it successfully,but if not done right, there can be interference with the chain. |
