I really wish the paint was in better shape. The parts that are intact are just stunning in the sun

I’ve learned to descend with a knee on the top tube just in case, but it really doesn’t show up unless I sit up and ride no-handed.
I get wobble at around 15mph as well. Seems to be a bit of a quirk for the big Trek 71X series.

Curiously, when I added the handlebar bag, it got much less pronounced. That was the exact opposite on my Tempo when I through a front bag on it. I expected the bars to go totally sideways the first time I took my hands off, but I am actually able to ride long enough no-hands to get a good back stretch.

Interesting, I get more pronounced speed wobble with weight over the front wheel like your Tempo.

@mountaindave are you running 700c or 650b?

I know that going from 700x32 to 650Bx38 lowered the trail a touch, but not enough that I think would make a really significant difference.

Just this morning I got the wobble on my 79 930, with a decent load in the back. It happened when I stood up. I don't ride no hands anymore.

650bx38 - the max I can get with fenders without modifiying the chainstays. Mine is a mid-trail 710, so I had hoped it would ride well with a font load. Not so. But it’s still a fantastic ride and I love it.

I've been working on a couple Treks, one that I've had for a while and one that I've had in my garage for about a year.

My trusty-and-no-longer-crusty '90 or so Trek 520:






I reused some Newbaums for now as I'm going to make some more tweaks to the cockpit. I'm on the lookout for some 46cm Salsa Cowchippers if anyone's got a lead. It'll get a front bag support soon, too. It's a land yacht on those 43mm Gravel Kings.

And a '91ish Trek 2100:







I was very hesitant to invest in an old bonded carbon frame, but some other projects recently posted here inspired me to finish it up. I'm really glad I did, I think it's my favorite ride. It's going to get some more pampering and upgrades soon, but it's a fantastic ride as it is now.

Snagged this 92 1400. It needs to be disassembled and thoroughly cleaned and lubed. I want to find a better wheelset than these Alexrims, something more fitting. But it is ridable and feels good.

This is a '79 937 I recently aquired from @tarsi - tarsi I just finished building it up and haven't even taken it out yet for a shake down ride. Been too cold here recently, but fingers crossed it will warm up soon.

Beautiful. Glad she found a nice new home and will see the riding she deserves.

Already posted it there! That's what what me think I should post it here in the Trek thread too.

Thank you very much, I can't wait to ride it this spring. I was going to take it out this afternoon, but then it started snowing again, lol.

That's spectacular!!!

I've got a 79 730- same geometry, but 531. It's a great riding bike!

Thanks you all for the kind words - it's got "inside house" display status so I can look at it in my office loft. As nice as it is, I'm still going to ride it regularly like my other bikes or at least try to!

I still need some more time between the saddle and handlebar bag before I can decide if it rides well without modification. I've been duped by novelty before

Looks like for your 1979, you should have 45mm geometric trail with 12mm of wheel flop

I've got 52mm geometric trail and 14mm flop. Objectively yours should behave significantly better.

I've got a 0.5° steeper head tube angle, but the 10mm less rake on mine might negate the gains from that half degree.

Correct. I was just riding it back from the gym today no-handed with an unladen handlebar bag. It’s doable at speeds below 15mph, but I wouldn’t go above that. I can sense its squirrelliness. I’m quite looking forward to swapping in a low trail fork!

I just experienced the exact same thing! Finally went on a "real" ride with the Campy shifters (not just around the neighborhood) and had shimmy above 15ish. A knee on the top tube solved most of it. Not a huge deal, I don't really want to be riding no hands above that speed much anyways

It looks like I failed to answer one of your previous questions about shifting earlier. The group shifts quite well. I still need to get used to the biomechanics of exactly how much to throw the levers to get a clean shift, but overall I am very happy.

It was my first ride with index shifting in close to a year, I had forgotten how nice it is I'm a big fan of the Campy mechanics, especially with the left lever trimming options. It does a great job of combining the best parts of brifters and friction shifting. Ergonomically they feel great too!
