The oil I have is "universal oil" (100 ml) bought on a supermarket for car tools and spare parts. It doesn't say anything else about it. The chain lube I have is CRC Chain Lube - it says "Adhesive Lubricant" on the can. I expect your cables are shot, and that the rest will work with cleaning, lubrication, and adjustment. 7 speed stuff is pretty durable. OK! I get back to you tomorrow God willing. -- underground experts united http://user.it.uu.se/~embe8573 |

You must have visited the site like five seconds after I submitted the post. Anyway now it is done. Nope. I checked it again at about 0800 PST on a different machine. I also cleared the browser cache and DNS cache to make sure I was not looking at a stale page or site. The pages now work, after you fixed them for Sir Ridesalot. Indeed! I understand now how this happened. Because I was certain I had changed the permissions already. But I changed them on the server! So when I transmitted files from my computer, the permissions were still non-read on the local machine. But because the files were there, they were not transmitted, only silently reset to the old non-read mode. -- underground experts united http://user.it.uu.se/~embe8573 |

Step one: Flush it with WD-40 and the replace the displaced grease with Tri-Flow. By "it", you mean the derailers? OK, Tri-Flow. Step two: If that didn't work, replace it.

Again, what do you mean by "it"? STi is a Shimano brand name but we take now 'STi' as a general term for indexed gear systems. I think he meant your shift levers and yes a light spray such as WD40 is often helpful inside them. Don't disassemble the shifter, just copiously flush it through any/all apertures. Newspapers on the floor recommended. Investigate your cables first, they are the most likely source of your troubles and cheap to replace. As others have replied here previously, disconnect the cable anchors to see if the changers move easily by hand. If they do, replace cable set. Control cables can be cleaned and lubricated (if not kinked or split or frayed) but they are so cheap that your cleaning time may be worth more. YMMV, as always. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

I have a stack of newspapers around but the floor is wood and has seen much worse than dirt and "dislocated" grease Investigate your cables first, they are the most likely source of your troubles and cheap to replace.

Control cables can be cleaned and lubricated (if not kinked or split or frayed) but they are so cheap that your cleaning time may be worth more. Now I have replaced the wires and cleaned and lubricated the cables. The controllers were a bit slow to get free and open but not difficult (1 hex + 2 Phillip screws). I cleaned and lubed them as well (the entire things). I put everything together, wires in cables, and hold the wire while trying the controller. Both work great and click clearly into each step with the wire running thru the cable with no tangible resistance. Now I put the cables back on the bike which was also easy. However here the easy stuff ends. Is there some method to what to do next? I thought I'd figure it out because the combinations seemed limited what to do. However I didn't succeed. On both front and back, either the wire gets ridiculously loose (like a loop) *or* I gets so heavy I have to put considerable strength into getting to the next step. Not possible to do while riding the bike! How do you do it? -- underground experts united http://user.it.uu.se/~embe8573 |

Not possible to do while riding the bike! OK, I got it working! With a tight wire it is possible to shift when pedaling (with the legs). I don't know if that is normal or if it is still a bad sign it can't be done with just a little force to it. I discovered two little screws (PZs) on the front mechanism. It says H on the left and L on the right. The "H" is perhaps "horizontal" (?) because it moves the arm between the saddle frame pole and the chainwheels. Actually you can align the arm pretty far to the right this way. Is there a method to this? I understand the purpose but it wasn't the easiest thing to detect a good position or tell a good one from a bad (save for when the chain came off). The L screw tho I didn't see anything happening. What does it do? -- underground experts united http://user.it.uu.se/~embe8573 |
