Downtube Shifters
I am wanting to put downtube shifters on my Trek touring bike. I see lots of shifters on ebay, but most are for two chainrings and my bike is a triple.
Since the shifters only work in friction mode on the front derailleur, will the 2x7 shifters work with a triple chainring setup?
Thanks

Nothing matters when running in friction mode. Even with index, it was common to have index for the RD, and retro friction for the FD, so if you have an index RD that's also an option.

Yes, the RD is index and the shifter is SIS. The Front shifter is friction only. So, I'm taking it that they will work fine? Also, my bike currently has STI shifters on the handlebar. I hate these shifters as they are failing on me all the time. Anyway, the cables run through a mount on the downtube that is where the shifters would mount. Can I just remove these cable mounts and mount the shifters there without any problem, or will I need something else to mount them?

bending over to shift and taking a hand off the bars , will get old soon enough , as you may find out..
been there done that.. long ago ..
hence the popularity of bar end shifters or the combo brifter.

I have resurrected quite a few sets of "non" functioning STI shifters doing the flush and lube.

I've used downtube shifters for many years and have never had a problem. If I'm on the tops, which is where I normally ride while touring, I don't have to bend over at all. I simply reach down and shift. No body movement at all except for my right hand. I have considered barend shifters, but believe for touring the downtube shifters would be more reliable and easier to make repairs on should I need too. Of course I've never used barends, so I may be completely wrong about this. I guess I'm just going back to what I know best.

If the frame is a bit older and has bosses for D/T shifters that have been converted to cable stops with something like these, then removing the part is all you need to do. However if the frame was built more recently, odds are it was built for HB controls, and has only cable stops brazed on. In that case you'd need band mount levers, since to my knowledge nobody makes a reverse (stop to lever boos) adapter.

The STI shifters will work better if you flush them out. If you use nearly a whole can of WD-40 solvent on them, they will clean out and loosen up all the hardened grease inside them. Then lube them with a good lube and they should work flawlessly again for a long time.

I just use whatever I have, but everyone has their own choice lube. The key is to use WD40 at first to flush the snot out of the shifters. I take them off and hold them upside down and keep squirting WD-40 into them while working the ratcheting levers. They will start to feel better and better as you clean them out. Some also use an air compressor to blow the dirt and WD-40 out after cleaning them before lubing them.

A bike mechanic told me not to use WD 40 for flushing out shifters, but instead use boiling water. Soak for a while. Let it dry, and then oil it up. Make sense?

These days one has to be very careful about heat of hot water around bicycles. Hot tap water is fine, but boiling water is above the temperature which can damage many plastics.

Well, I had my doubts, but decided to try it anyway, nothing to loose. So, I took the bike out to the shop and sprayed it down good with WD40. I sprayed in every hole or opening I could see and within just a few minutes it started to work. Sprayed it down another time or two and it works great now. I blew it out real good with the air compressor and now I'm going to let it sit over night to air out and dry out a little. Tomorrow I think I'm going to try the white lithium grease in the spray can and see if I can't get all down in there real good.
I really appreciate the help and suggestions from everyone.

in your second post you said "I hate these shifters", then some stranger on an internet forum implies that with a little lube they might work, then it's "I'll have to give that a try".
you sound like my first wife. as long as i was bringing home that weekly paycheck, everything was fine and dandy. lose my job, sit on the couch in my underwear with an occasional beer for a couple of weeks, and all of a sudden i'm not good enough for her...
good to hear it's working.

Don't let anyone tell her about WD-40

I agree with you on the brifter (combined brake and shifter) setup. What an elegant design solution.
However, I disagree with you that bar-end shifters are superior to downtube mounted shifters. I've done both (as well as stem shifters) and much prefer downtube to bar-end. Personal preference, perhaps. Best. DB

Keep your hair on, doodlebug. hueyhoolihan was on the money, and amusing to boot.
You hated the STIs, and now they're apparently fine for your purposes. BTW, I hope you didn't get WD40 on the hoods... they don't like that.

FWIW, I used spray white lithium grease on my Shimano mtn bike shifters and found that they got gummed up too soon, much sooner than I expected. YMMV. Now I flush them out with mineral spirits, blow out with compressed air then lube with DuPont Teflon Multi-Use lubricant (the new stuff without wax) from HD or Lowes or someplace. This is the same as Finish Line lube but cheaper and does not have the Finish Line panashe. A year later so far so good. I may stand alone here.

dont see front panniers on bandura's bike downshifting on a loaded tour bike on a hill with a touring load
is different than another day ride on a road C&V rig.

As to the WD40, I was careful about not getting any on the hoods. I read somewhere else that the stuff would damage them.

You need to have thicker skin here on BF. You asked about installing D/T levers, and about half the responses were about "better" alternatives. That's about par for the course. As for the "like my ex..." comment, not surprising in the context of the thread, and in all fairness it was kind of funny.
It's your bike, take the advice that you want to, ignore the rest, and don't feel obligated to justify your choices to anybody.

Triple crank, Crane GS rear derail all operated quite nicely w/ Campy DT controls while loaded fully, not particularly taxing when one develops the technique and keeps at it for several decades.
My Rando-ish build is being converted to a triple this spring, indexed DT controls make shifting a doddle.
To each their own,
