1984 Trek 760, The Newest Edition to my Bike Family! (Easthill READ ME)

So, after doing some market research (AKA consulting you guys), I decided to go check out the bike even though it's the furthest I've ever been shopping.

I tried it out and it felt really sweet. It was heavier than the peugeot that I just sold, which was unfortunately a little too big for me. When I was trying out the Trek, I looked for the roughest patches of road that I could find, and to my surprise, I couldn't feel them. The bike just absorbed every patch of bad road that I could throw to it.

The frame is in pretty good condition, some road rash here and there and a few scratches on the frame. The frame is Renolds 531P (Professional, which is lighter than regular 531 it also has a 200lb weight limit). The parts are in decent shape too. The groupset is suntour superbe except the RD was swapped to a Shimano 600 for some reason. The shifting is a little sloppy but I think that can be remedied with a few simple limit screw and tension adjustments. I actually want to swap out the parts for 10 speed 105 stuff that I can get for a good price, and I might be putting the superbe stuff on ebay. If any of you are interested let me know and I'll put it up there as a closed auction so you can get it via buy it now or something.

I don't know how to do much of my own work, but there's a shop nearby that doesn't charge for labor and only charges for parts so I might take the bike to them and watch while they swap out the shifting cables because they're a little rusty.

I have time on my hands over the next 2-3 weeks since I'm at home from college and I want to get this bike cleaned up and working beautifully.

Anyway, without further ado. I present my 1984 Trek 760. With this buy, I also got the original sales receipt and catalog! Huzzah!

PICTURES!







The wheels hubs also have this metal thing on them and I have no idea what it is.


Enjoy the pictures and if you have any tips for me on how to get this bike pretty and better working again, please let me know. Also, If you want me to post a different view or closeup of something I can do that if you ask!

Have a good holiday everyone!

Those are clips that cover an oil port. The idea is that you flush the hub with oil every so often and it pushes out the grit that would otherwise shorten the life of your bearings. Generally found on higher end hubs.

How would I do this, I still haven't cleaned the dirt off the areas yet. But how would I put in the oil and let the grit out?

The bearings feel a little gritty and this would be a nifty way to clear them out!

If things feel gritty I would do a full overhaul of the wheel bearings.

Many older bikes were oil lubricated and these ports allowed one to keep the bearings lubed and an oil lubricated hub will spin like nothing else you've seen.

For the long term grease is a far better lubricant.

I have an '82 Trek 750 and can really appreciate how great a bike these are.

First thing, it needs a good cleaning. Start taking off the parts, one at a time and give them a thorough cleaning. Read the Park Tools website about working on each of these parts, before you take it off. I personally I prefer to have Leonard Zinn's book in front of me, because I am old school. There are somethings, like the bottom bracket, headset and hubs that require special tools, that should wait until last. At that point, you can decide whether you want to invest in the tools or take it to the shop.
The chainrings look a little worn, but it is hard to tell with all the dirt. They may well need to be replaced. That would mean the freewheel and chain need to be replaced too. But if you are going to convert to 10 speed, you will be doing that anyway.
The cable housing looks like it has seen better days. But, again in the 10 speed conversion, the shifter housings will need to be replaced anyway. Old fashioned housing won't work with indexed shifters.
Replacing the brake cables and housing is one of the easiest DIY jobs around. The hard part will be picking out the right color. There is a good chance you will damage the hoods when you replace the cables, so be prepared.
Don't mess with the oil ports in the hubs. Those were for racers.

I might just buy the 10 speed stuff and put it away to work with at a later date. For now concentrating on fixing up the frame and cleaning everything up. I'll start with the small stuff myself, but the girlfriend and I have some bonding time which will certainly involve us hanging out and taking this beauty apart and giving it a good cleaning. I'll probably leave the bike at her place and go over every day/other day and work on it with her. Should be a blast.

What should I do to clean it and take it apart, I've never taken apart a bike before and while I'm psyched to do it, I'm a little weary of what I could do wrong.

The first adjustments will involve fixing the limit screws on the FD and RD to get rid of the chain rub and actually use all the rear gears. Also wiping down the chain and lubing it. I have a 7 speed chain at school, I'll put that on later. I need to check for wear.

Does anyone know what the superbe parts might be worth if I decide to swap everything. I'm too young to have a sentimental attachment to this stuff, but I can look at it and tell that it's awesome stuff.

Edit: I'm still curious about the oil ports on the hub. Is that an easier way to clean out the bearings or should I repack them? I watched and learned while my friend did it once and I'm wondering if it would help me keep the hubs in good condition and would make them work better.

+1 on the Zinn book (around $20 at most book stores). With a few weeks before school starts back up you should be able to guide yourself (with the Park site, or Zinn book) and be able to do a lot of the stuff yourself.

+100 to all this. Bike repair ain't rocket science! Or particle Physics!

You won't regret that Trek.

If you're going to put a 9 speed group on it, the chainrings will definitely need to be replaced.

FYI - I was putzing around starting to assemble my 760 tonight. The Campagnolo Chorus RD stop screw doesn't contact the part of the dropout that normally limits rear derailleur movement. I though I had everything I needed, but evidently I'm a part short. Just giving you a heads-up, as this might possibly happen with your new 105 group also.

Nice find!! I love old Trek road bikes!! Looks like you're loving this one already, hehe. I just converted my 83 560 to newer Trek wheels, 7 speed, and Rivendell pods with Nashbar shifters. With a Shimano 105 RD, the combo works like a charm.,,,,BD


EDIT: Sorry didn't mean this to sound like a 105 comment regarding your post US. The 105 RD I used is probably late eighties, Charcoal and alloy colored.

I was going to upgrade to a 10 speed group, so I'd need the thinner chainrings. Part of me wants to race on this bike, but I figure that's not going to happen so I might end up saving the money and just enjoying the bike. I do want to clean it up and make it look purdy though.

Thanks for the heads up though!

The 760 is a bonafide race bike according to what I've read, including the use of 531P steel instead of regular 531. The 770 was the campy version of the bike and the 170 was made of 753 steel (lightweight as trek refers to it)and was campy super record like the 770. This is straight outta the catalog i got with the bike. According to it, the campy version weighed just over 20 lbs. This feels heavier, not sure why, but the saddle on it right now is a huge gross avocet touring saddle (a womens saddle maybe). I'll use it for now, but the saddle needs to go and eventually I'll put bartape on instead of the stiched foam pad that's on it now.

The picture's also taken at an angle so keep that in mind.

Those rivendell pods sound pretty cool!

I miss my peugeot (and the nice wheelset that was on it when I sold it I shoulda kept the campy hub rear wheel and the 105 hub front wheel both laced to mavic rims!), but it was way too big for me and I'd been hit by the top tube atleast once when stopped on a a little hill. This project is going to be sweet. I can't wait to have fun working on it myself and bonding with the gf while we work on the trek. I think she might have been more excited to be working on it than I was!

Just kidding, but she came close!

Edit: Just for kicks, does anyone know what the superbe parts (Brakes, shifters, levers, FD) on the bike might be worth. I'm curious so I can decide on the 105 upgrade. I kinda want to keep things the way they are for a while though.

Rivendell pods and Shimano shifters from nashbar, and vinyl black wrap(Ambrosio) from Pro Bike Kit. The fork crown that's on mine is really sloping, with almost no shoulder. Yours is straight across the top, as in 90* corners. Never seen on like that except on old school bikes. Dunno.,,,,BD

This pic has the pods/shifters, and you can see what I mean about the fork crown(top near the yoke).

Way to go man! My 85 Trek 400 was my first road bike - bought it 7 years ago when I moved to New York. It's served me with nothing but solid rides and I always go back to it with a smile after riding my other wheels. Two years ago I took the whole thing down to bare metal (it was a bad red) and built it back up a metallic charcoal stealth bomber. My girlfriend got me a Brooks Pro for Xmas and it's riding great. If I were you I'd get rid of the fuschia Trek decals and throw on a tan B-17 and some leather bar wrap.

Get in good with a local bike shop and don't be afraid to get greasy prints on your Zinn and enjoy the madness!

The 753 frame weighs the same as the 531P. Main difference is the 753 tubing is a little stiffer.

Thanks for the photos! It doesn't look as if it needs a lot of work, either.

You posted this just as I was getting ready to go do other things last night .

Merry Christmas for ridethecliche !

I could feel the bottom bracket move under me when I stood up and cranked, resulted in chain rub on the FD. I was a little surprised, the peugeot did that too and I only weigh 140 lbs!

I kinda get what you're referring to. I think that's because mine has a lug there and the lug has a straight instead of sloping side. Maybe it makes it stiffer that way, who knows.

The 760 had a Reynolds 531p fork with a Tange investment cast crown, while the 560 had a Tange mangalloy fork with a Tange Aero crown.
I am not sure which is better or why they were different, they just were.
