Two clicks per shift works really well. I am wondering if there is any way to make this into a one click system - some way to make it skip a click perhaps. I haven't tried to dissect the shifter yet. I thought I would ask first and see if anyone has done something similar or at least who understands how to take these shifters apart without destroying them.

I have a small crack in the rear of the frame where the seatpost would insert on my 2003 Cervelo Soloist (alum).

I have been reading in this forum about TIG welding as an option but was curious to see what other thought was the best fix. The mechanic at my lbs told me this crack when fixed SHOULD be okay as it doesn't receive an overwhelming amount of stress. Is this accurate at all?

Is this crack worth fixing? I am willing to pay to keep this frame in use if it that's the big factor. Thank you in advance.

I'm having trouble getting the RD to shift right, though. It used to shift "like butter" back when it and I were young. Now, it doesn't.

The bike is mostly stock SunTour/Sugino/DiaCompe. The only thing in the drivetrain that's not original is the freewheel (and the RD--see below). It came with a SunTour 5-speed freewheel that wore out. I replaced it with an NOS 6-speed SunTour ultra-spaced freewheel. It never shifted right (from the time the 5-speed started wearing out, until now). I've worked things out mostly, except for one thing: it likes to double-shift, when shifting downward, between the middle great on the freewheel (2-->3 I usually end up on 4; 3--> 4 I usually end up on 5). In trying to sort it out, I've replaced the cables (of course--always an easy first thing to do), chain (SRAM 8-speed), rear derailleur (original well-used sloppy SunTour VGT Luxe, for tight NOS SunTour VGT Luxe). I've adjusted the b-screw on the derailleur, the pivot spring tension (easy to do on a VGT Luxe). Each of these things has made it a tiny bit better, without solving the problem.

What remains?

Chain length: I made the new chain the same length as the old chain. Actually, I didn't "make" anything. I didn't have to take any links off the new chain--it was already the same length as the old one. Some time in the mid-'80s I did take 2 links out of the old chain (why, I don't recall), but it still shifted fine at this length for years after.

Difference between the old FW and the new one: The original was a "typically-spaced" '70s 5-speed. It was either 14-32 or 14-34. The new one is a 14-34 6-speed. I don't have good enough calipers to measure it, but the I believe it's got narrower "ultra" spacing (I didn't have to re-dish the wheel when I put it on). This ought to get along fine with the 8-speed chain, though, I think. I don't have the old 5-speed anymore (drat!), but I do believe the 5-speed's middle cogs may have been bigger than this 6-speed has. If I adjust the b-screw so that the jockey pulley is closer on the middle cogs, it's too close to shift to the 34-tooth cog (josckey wheel bangs into the side of it, in fact).

Bent hanger? To the naked eye, it looks fine. Perhaps I should take it to the LBS so they can measure it, but then they might want to do everything, and I've been fixing this bike myself for 30 years! [pride]

I've been working on bikes since I was 12, and on this bike since I first bought it, new, in 1980, so I know my way around a bike. Have I lost my touch ?

I wish I hadn't tossed the old freewheel. As I recall, the teeth were very worn on it.

So, what do you think? Should I try a different freewheel? Something else?

Picture here, as it looked before I replaced the chain and the RD. You can kinda see the big jump from teh low cog to #2:

I've been rebuilding and repairing a garbage-picked Huffy English 3-speed. Project bike. The rear hub is a Shimano, not the classic SA. It's been baptism by fire - learning how to do it as I go.

Right now, I'm working on the chain. My problem is trying to figure out the length chain I need. There wasn't a chain when I found the bike. I have a few spare 1/8" single speed chains (for, like, a BMX bike) that I've decided to use for this 3-speed. But each is about one-half link (or, I guess, one link) too short to fit on my 46/19 chainrings on this 3-speed. I have a master link, too, and some spare 1/8" link sections lying around.

I'm not sure if I should add a whole link to the chain I'm using, go out and buy a new chain, or slide the rear wheel forward in the dropouts to compensate for the half-link short. Will extra slack with a whole additional link be a huge problem? I'm not well-versed working on single-speed bikes, and don't want to bastardize a chain that may break one day by adding links to it.

Not exactly sure what other information you need to shed some light on this, so let me know if I can post more info about what I'm working with.

There are lots of threads on this topic and I've read quite a few of them. But would like to pose a few more specific questions.

First of all, I have a 2008 Specialized Allez triple. It originally came with Sora Front (triple) and Tiagra 9sp rear. It has the Sora shifters and Tektro brakes.

I have since changed front and rear to Shimano 105. I still run the Sora shifters and everything runs perfectly fine. Except for the fact that I'm outgrowing the Sora shifters and looking into bidding on these (Campy Record Carbon 9Sp shifters):

http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT

Here are my questions:

1) I know I will need a JTEK shiftmate to get the rear der to shift correctly. Will these shifters work well with the 105 triple front?
2) Are there any concerns compatibility between my Tektro brakes with these levers? Any workarounds, etc?
3) Lastly, If any of you bought shifters like these from Ebay, what price should I expect these shifters to end up at the end of the auction. Guess I can wait and see..
