One was already chewed up beyond use and the other just came apart in my hand. The spring has gone to that place where single socks and lost guitar picks live. Is there a source for these?

Thanks in advance.

Unless someone like "loose screws" reopens, I doubt it. This is the kind of stuff that bike shop mechanics pull out of the cannibal or scavenge box.

I might be able to make those work, but I was referring to the adjusters that are at the lever.

Thumpic- Your op was confusing. For which cable, brake or gear, are you talking about? Where along the cable's route are you talking about? Many frames, brake calipers and ders have adjusters built into them. So what are you actually looking for? Andy.

I'm sorry, I thought it was pretty clear. On my STI brake levers are barrel adjusters. They are unusable. I was asking if there was a source for replacements.

It might have helped a tiny bit if you specified mtn. Though there are no adjusters in road levers.

Thumpic, If the brake body is phenolic resin there is also the possibility that the threads are trashed in the body.

thumpic,

Try your local bike co-op... you might be able to find a pair from an old set of levers.

FYI... these adjusting barrels fit into a recessed filling on the brake lever that was not threaded; all the adjustment was built into the 'barrel'.

Back in the day when this stuff was all new, STI was the idea that the shifters and brake levers were one integrated unit, instead of being separate pieces.

Yes they are, STI covers both road and MTB, it stand for Shimano Total Integration, and covers all combined shifter / brake levers, STI was printed on MTB units from the early 90's (Rapidfire era), although now the term is primarily used for road shifters now.

The Shifters the OP has look to be from the Rapidfire era (200GS?) / 1990 ish, for spares, this is long after Shimano has stopped supporting them, so either co-op/LBS with good spares from broken parts, a current barrel adjuster should have the same thread, and there are plenty of non shimano options, check out a search for brake barrel adjuster on ebay.

I've bought metal adjusters just because I did't like the plastic ones on the Shimano MTB levers. It's been a few years, but I think it's likely that they were made by Problem Solvers.

I understand what STI stands for, are you saying you can shift with those brake levers? As you can tell, I'm not a mountain biker and should have stayed out of this thread.

I you look at the photo in post#6, you can see Shimano Total Integration printed on the shifter pod body, the shifter pod is integrated to the lever, as in it cannot be removed and installed separately. STI has nothing to do with being able to shift with the brake lever, its the integration of the brake lever & shifter into one assembly.

For MTB's this culminated in the DCL concept (where the shifting was done with the brake lever), which lasted for a single generation, now MTB STI's are available upto Alivio level, from Deore on, you get separate shifters & gear pods.

Currently, Ispec is the closest you can get to higher end MTB STI , by mounting the shifter on the brake levers handlebar mount, by using compatible brake lever & shifter pod cover assembly. SRAM use a similar system with Matchmakers

For staying out of a thread, the is BF, you have to have your say

Actually,it's only used for road brifters. I've never heard anyone use the term for flat bar shifters,not even integrated ones. That's why I posted those adjusters.

Are the shifter mounts(where the adjuster threads into) plastic or metal? If plastic,I'd say it's time for new ones. If you don't want to buy new ones,then you could go with the previous poster's recommendation of a co-op/bike kitchen. If they're metal,you might be able to get something like these to work:

You may want to tell Shimano that, and the designer who had it printed it on the part in the photo on post #6 .

STI is now the term mainly used for road bike shifters, but in the past, and still for lower end groupsets, has been used for flatbar brakelever/shifter units, this is clearly shown on the Rapidfire units in the photo (they are from the age of the 200GS series, although if anyone can ID the exact model, post up).

I'm saying most people only use it for road brifters. I'm sure most of the folks who responded thought the OP was talking about brifters.

When I first saw the post, I was thinking about inline barrel adjusters for road bikes, like Shimano CA70's As with everything bike related, you have to be really specific if asking a question, bit like saying 'I have an issue with a 105 STI'; that covers 3 difference speeds and 4 generations (5500,5600, 5700 & 5800), confusing!!! It can get confusing very quickly unless the question is very specific about the exact part in question.

Judging by the photo showing the Cantilever arches and plastic covered metal levers, I would estimate that they're 300 or 400 LX integrated levers & pods.

FYI... until Dura Ace Integrated brifters were introduced to the marketplace, STI was strictly MTB domain.

A picture does say a thousand words...
