need help with a bike...please...
I have an old trek 400 road bike that i've riddin the hell out of..eight RAGBRAI's..and multiple long rides, however this is a bike with a double chainring and a seven speed freewheel..i'd really like to put a triple chainring on her and possibly go nine speed (friction is not a problem). It currently has shimano DT shifters and i'm fine with that as well.
Here's the deal, I already have a shimano XT long cage RD, and a sugino triple chainring as well as the proper BB, i'll be takin' this to a LBS, not sure of what FD i'll need or if this is worth the cost, but I gotta say this bike fits to a tee and i've riddin it thousands of miles. Problem is i'm not gittin' any younger and could really use the gears, so far i've managed the hills but they ain't gittin' any easier!
Just want to know what you experts thing...thanks so much for listening..take care..
Is your Sugino the XD-600? Up through 2008, that came stock on Surly LHT paired with a Tiagra tripple FD, so I would think the Tiagra would be a sure bet. The folks at your LBS will know for sure as far as clamp diameters, top/bottom pull and swing. Don`t worry- what ever they set you up with a new FD will run much less than your cranks and RD.
Aside from that, I`m not sure what else you`re asking, if anything. I have some comments about going to 9-speed though. You might find that the smaller rings on your new cranks leave you with a range you`re happy with without changing from your 5/6/7 speed. If you want lower still, IRD still makes freewheels with bigger sprockets than most others. They`re not cheap, but much less than a whole new wheel. If it`s the tighter gearing from a 9-s cassette that you want I doubt the IRD freewheels will help. Also, keep in mind that 9-speed sprockets are physically closer together, so friction shifting won`t be as simple as what you have now. I`ve never used friction for more than 6, so I`m just going on hear-say for this- try it and see. Indexed will certainly drive your bill up, but it might be worth it to you. For what it`s worth, I just bought Shimano 8-speed indexed/friction bar end shifters brand new for $56 plus shipping from Jenson- not too expensive. If you have the patience for eBay or Craigslist, I`m sure you could do better still. Have fun with your mods!
EDIT: It seems to me that 7-speed and 8-speed Shimano are the same spacing (sprocket to sprocket). If you happen to have 7 speed indexed now, it might be possible to use it, still indexed, for 8-speed. Maybe somebody who knows for sure will answer here. If not, they`ll surely know in the mechanics` lounge.

thanks so much for your reply...not really sure which sugino crank i've got other than i'm pretty sure its a standard road triple...i'm just not sure if I wanna do this or just go with a new touring bike ( LHT comes to mind) I just really love this bike...just don't wanna throw to much moola at it..but i've had these parts for awhile so the other cost shouldn't be to bad...again thanks!
I think the new LHTs are running around $1100. A front derailer runs... $40? Even if you go whole hog with a killer wheel, 9s indexed shifters and cassette you won`t end up spending anywhere near the price of a new LHT. And in my book a new LHT isn`t anywhere near as COOL as an old steel Trek!
