upgrading woesmetonymy3

I'm upgrading from downtube to STI (DA 8spd) and I need cables, housing, and those little adapter thingies that go in the downtube bosses. Where can I get all of this stuff cheap. My LBS said about 30 bucks for mew cables and housing, and they told me that I need new shift and brake cables, all the way from the levers to the deraillers and calipers. Is that right? And then they told me that the adapters would be 30-40 bucks?!? They're kidding, right? Is there anywhere I can get these for cheaper, or does anyone have an old pair lying around they want to pawn off? Thanks.

already have the levers?Dog

Usually all the cables and hardware comes with the Sti levers.

If you have the levers without the cables, etc., check . I think they have everything you need. You really do need new everything, though.

I bought 8spd levers used (I don't know a place to get them new). And they're w/o cables and housing. Even if they weren't, I don't think I'd want to use the old stuff.

Ok, I guess you do need everything, but why? Why aren't the old cables good. Is the diameter off?

And, if I go to the Excel Sports cables & housing page, which cables do I need?

And I can't find the little adapters there either. No one seems to have them! Thanks.

Holy cow. I thought you'd get away with simply buying a brake cable set and 2 derailleur cable sets pretty cheaply. But then $29 for the stops? That's nuts!

Of course, you need much longer derailleur cables compared to what you had. That's pretty obvious. Then, I think the lead (or whatever) cable end on the Sti levers is different from a standard lever. You might get away with the same brake cable housing, though.

Just go to a shop and tell them what you need. They probably have some cheap generic stuff that will work. Don't know about those stops, though.

LBS's with all the tools and all the parts on hand have been far more than reasonable in their labor rates to do most of the *work* on bikes. This is especially true if you've developed at least a first name basic relationship with them and you buy the cables and etc. that they'll be installing.

well, ok, stops aside. Let's assume that I can find some on Ebay or used. What cables do I need to buy? On the Excel site, shimano has these listed:

Shimano Brake Cable Road $2.49
Shimano Derailleur Cable $2.49
Shimano Dura-Ace Brake Cable Set $11.95

I don't really want to buy from the LBS, because lately I seem to be getting ripped off. A guy tried to charge my $90 for a salsa quill road stem. Excel has em for $59. I'd like to buy from the local guy, sure, if the prices are marginally higher. But 40 bucks for cable stops and 30 for cables and housing? I've got a friend who'll help me do the labor, I like to do it myself so I'll know how to do it the next time, so I really just need to find some lousy cables.

Doug said I could just replace brake cables, and not housing. Good, because I've got rear brake housing that runs through my top tube and would be a pain to put back in. Front brake, I can use same housing. Front derailleur has no housing now, though it will w/ STI. Now it just goes straight from the lever, under the BB, up the the derailleur. The rear derailleur goes from the lever, under the BB, along the chainstay w/ no housing, but there's a little strip that goes around to the derailleur. I assume I could keep this. So 2 "Shimano Derailleur Cable $2.49" (which don't include housing right?) and 2 "Shimano Brake Cable Road $2.49", which I can use inside my current housing, and will be long enough, right? Then I just need a little housing to go from the STI levers to the downtube stops, and the Shimano Derailler cable will be long enough, correct? So where do I pick up this housing?

Or is there a much better way to do this? Please help!

Duh, I just saw the 4mm deraileur housing on the same page on that same page. If I got all of the stuff listed above, plus 1 order (5ft) of this housing, would that be the right thing?

Your LBS is ripping you off if they want to charge you $30-40 just for the downtube stops. I've seen them being sold on ebay for $10-15. I bought from my LBS for $20.00

Geez, what's the big deal? Installing a new set of cables and the cable bosses is pretty easy. the tricky part is making sure you use the right cable and housing for the brake and shifting systems - they aren't the same. You should be able to pick up a set of cable bosses used from a LBS or some local bike junkie. Problem is you don't seem to be on good terms with your LBS. Unfortunately Shimano charges a fortune for small parts.

You should make the investment and run new cables - they'll operate smoothly while used ones can get pretty gummy and then there's the safety issue.

If this kind of stuff bums you out you should seriously consider if you want to do you own work. Why not hit the guy up that sold you the levers for the cable stops - it's worth asking, but he may be using them on his new system.

In general you need to be pretty careful when buying used stuff - not only for potential quality problems, but you may not get all of the miscellaneous parts and not know it unitl you go to install stuff. then there's the whole sizing issue.

Checkout for killer deals, odd stuff, and great service. make sure you check the closeout section.

I made that upgrade this year (Shimano 600) I used the same brake cable, the length doesn't change. mine came with the stops though. Bike shops always say things aren't compatible.

Since you did this and it worked, can you tell me a few things? Brake cables worked. Great. so all I need is some 4mm derailleur cable and a little generic 4mm housing for the part between the levers and downtube stops. And dt stops, of course. Anything else? an extra bolt here, a little barrel adjuster? Thanks.

The only barrel adjusters are already on the rear derailuer, and on the downtube stops.

Exactly what you said just the housing the two cables, and the downtube stops.

Good derailuer cables will make shifting nicer but make sure you get housings meant for shifters. This housing will not compress when tension is put on the cable

housing meant for shifters or derailleurs? Excel has some generic housing: 4mm derailleur housing. Is that the stuff? Or do I need special stuff for STI levers. I don't know where to get that. Thanks.

That will be fine. nm.vanzutas

cable stops...DrD

So if you really need cable stops, find a shop that builds up framesets which don't require them - they probably have some lying around in the parts bin! (they come with the lever set)

I'd been wondering why anyone would pay as much as they were going for on Ebay! now I know!

For cables/housing and adaptors - check out the third hand/loose screws - they have everything you need (they also list adaptors with barrel adjustors for alot less than $30! I'd give 'em a call) -
