The 1981 Trek 710 Project

So I've been acquiring a lot of Treks lately cause I like them but each has become a project bike, mostly for paint ('84 Trek 760), some for frame work ('84 Trek 610) and one was just to small ('85 Trek 620), which was a bummer. So I'm looking through ebay last week when a 710 goes off in my size. I pull the trigger. Paid to much and looks rough but I don't care.
So I'll just keep this thread up for the build so I know what I did later on when my memory goes further down the rabbit hole.



Looks like someone rode it as a cross bike. The Rigida Rims are beat up. The rear is a lost cause. I might be able to salvage the front. I'm sad but I'm not to upset... Now if they had been some Mavic GP4's...



The shape of the Concor makes me sadder than the Rigida's. I still might use it on the Trek 760 though since I am going old school on that build...someday



The wheels will probably get pulled apart as the rear is gone and the spokes are galvanized.

I'll keep the brakes. Everything else will be swapped.
I'm going 10s Campy, thereby allowing me to swap my wheels between my other bikes easily. I'll probably keep an SR front derailluer on it since you can't get anything in a 28.6 hardly anymore. The Veloce 34/50 compact crank will move from the '85 SR300 and I'll replace that one with a newer style Veloce UT crank. That way this one at least sports the Phill BB and square tape cranks. Nitto Technomic Stem and Noodle bars. Velo Orange hammered fenders (if they fit) and the Grand Cru Headset. Some leather or leather type wrap with some gel pads and a Selle An-Atomica saddle should get me comfy. I'm still deciding whether or not I want to grab a VO Constructeur front rack for it. But then I need the bag...

I'm keeping the paint for right now, just some cleaning and some wax. I may add some bosses to it later on when I'm ready to repaint it (It needs another bottle and pump peg for me) but I'm going to practice on the 610 first.

That bike looks like it'd be fun.

So for 1981- the x10 series frames would be the 'touring' series, right?

It's more of a sport touring frame. They didn't really have those designations back then but it has a longer wheelbase than their Pro frames of the time.

Finally some progress

Ok so its taken a long time...This first picture is progress from last week. The frame has been cleaned, the seat tube has been honed, the frame prepped with framesaver, polished and waxed. Not that it looks like it with all the chips and scraps on it. It came with 27" knobbies so I suspect I saved it from a life of cyclecross. Surprisingly for the scraps and missing paint there aren't any dings in the tubes.





I had to order a new Huret downtube shifter clamp since the campy ones I have are all built in for the friction shifters. The Huret was the only thing I could find that was exactly like braze on shifter bosses and would accept either my Campy shifters or my Shimano shifters. I also had to order brown brake cables at the same time so all that took an extra week. The last couple of days have been long work days so I only get a little done. Most of it has been spent stuffing the high profile 32c's I'm running under the brakes and front rack mounts. And don't get me started on where I have to go to find M5 and M6 nuts and bolts. I think they are made of gold, not stainless steel, they are so elusive at what we have for hardware stores anymore. but the rack is finally mounted, the seat has a seatbolt and none of the 32c's currently rub anything. But I am bummed I won't be running fenders with them like the Cannondale SR400. If I went to 28's I wouldn't have a problem..

I had to swap out my Campy front derailleur for the Suntour because the cable bolt threads wound up being stripped out on the Campy. I might swap it our for something else but right now I'll try it.

I had an '82 710 for a bit, and all I could fit in the rear was a 25mm, no fender. There was much more clearance under the fork crown, if I recall.
Nice frame though. The ride was super

To mount modern derailleurs on skinny vintage 28.6 down tubes, use braze on adapters and the braze on type derailleurs. The adapters cost $20 maybe.

For the stripped out Campy FD, if you cannot tap the hole to a larger bolt, perhaps you could drill the hole through the derailleur arm, then use a longer bolt and nut. A bit ghetto but who's going to look that closely?

As for the fender clearance, would a 650 conversion allow you to run wide-ish tires and have fenders?

This is cool. My next frame will probably end up being an early 80's Trek as I now miss my 620 sumthin' fierce. Well, it's gonna be steel anyway. Great work!
