I just fully restored an '85 Trek 600 complete with a nice JB paint job. I, too, had the Trek headbadge pox. JB had no solution. But I finally decided to just keep the tatty badge. My thinking? It's the one visible piece on the bike that looks old. Kind of a "tip of the hat" to its age and original owner, whoever that was. Don't know if that makes any sense, but it works for me.

My little homemade bracket doesn't look too bad in final fender installation. Even better, it works great. I could have sanded/polished file marks a little, but whatever:

I'm going w/stitch on leather handlebar wrap, but first I want to ride it some, make sure I agree w/all the geometry, stem extension and lever placement particularly. Only get one shot w/the stitch on stuff. So some quick and dirty tan cork wrap:

Went on my first real ride on my new Trek 620 today, post Irene. About 30 miles, mostly the loop of Rock Creek Parkway & Capital Crescent Trail plus a little bit. Lots of small branches and leaves in the road/path, but only had to do 3 portages around downed trees. I had done two shorter rides while my wife/son were here from Japan, but that was with trailer, so this was my first chance to see how the system really works. Ended up with 35mm Pasela Panaracer Tourguards, pumped to 60psi, a nice cushy ride:
That's a new Zimbale front rack bag I just bought. I'm pretty happy with it, nice quality, big enough for typical fair weather day tripping ride and completely out of the way unlike handlebar bags.
I originally fitted the fenders up for 28mm tires - the 35mm fit, but I'm going to rework them for a little more clearance.

That's a great looking bike, I know I said that before! I took the 85 Schwinn LeTour Luxe out and rode it 110 miles yesterday and got back at around 10:30 at night (using lights of course). Those touring design frames are great, you ride it for 100 miles or so and feel like you've only gone 30 or 40 miles, it's like going from a Lotus (my Miyata Team and 912) to a Cadillac ride. I still need to get some fenders for it that look better then the cheap black crap ones I have now. That Schwinn is now my all weather late riding bike, all my lights are on that one so if I know I'm going to out after dark I just take that bike so I don't have to transfer lights around.
By the way, it seems your tire pressure of 75 "might" be a bit high on the front and too low on the rear. Go to the link I posted and use the second calculator, not the first or third one, enter in your weight plus bike weight plus whatever gear your using weights, and change the percentage from 40/60% to 45/55% and change the tire size to 37 (their max tire size) and see where the pressure is according to the calculator. Try it and see what you think. https://www.dorkypantsr.us/bike-tire-...alculator.html

Actually, I had them both inflated to 60psi, I think I might roll the front down to 45-50, keep the 60psi in rear. Both your calculator and the bicycle classics tire drop seem to recommend something around this for my weight.
I'm looking forward to my first longish ride (more than 60 miles or so..). All the components are super high end stuff, brand new, so the operation is smooth as silk. The Berthoud saddle is very, very stiff, the only other leather one I recall being this stiff was a Fujita Professional and I think the Berthoud may be beating it by a nose. Fortunately, the shape seems to agree with me, at least on the short rides I've taken. The 30 miles today was continuous w/out stops except for a couple of portages around/over downed trees and the saddle was still quite comfortable, so that is a good sign for longer range comfort.
I did have 28mm tires on it for a couple of short/quick rides, but the steering felt a little squirrelly - the fork is fairly large offset and then going to 700cc wheels and narrower tires than what was originally specc'ed on the bike seemed to have lowered to the trail a bit too much. The steering feels a lot more stable with the 35mm which, on a 700c wheel gives essentially the same diameter as a 1-1/4" tire on a 27" rim as the bike was designed for and consequently the same steering geometry, more or less.

Excellent work, Robatsu. Looks real good, and the fenders jive nicely with the color of the decals. I like the painted(versus polished/stainless) fenders. Since you posted the link to Alfred E Bike, I've been going back and forth on pulling the trigger on some primer red fenders.
Since you've put some miles on it, are there any clearance issues between the fenders and the 35mm tires?

But in general, yes, these are definitely wide enough for 35mm tires.

Cool! I thought 28mm were a bit narrow for a bike of this style. I like how the 35mm tires fill out more of the space. Looks good.
Can you offer any advice for routing the RD cable through the chainstay? How difficult is it? Does the exit requite a particular type of housing end?

The cable slide right through the stay perfectly, just like slipping it through a housing, no muss, no fuss. I don't know how it is constructed inside the stay but it sure was easy.
The end of the stay has an inset for a ferrule. It is too small for a 5mm ferrulle. I used a step down ferrule that came with the derailleur - it is a bit small for the inset, can move around a little. I think it is a 5-3mm step down. It works fine for friction shifting but may introduce some inaccuracy for indexed shifting, which I haven't tried yet (the shifters I put on it have both index/friction mode). At some point, I'll probably round up a 5-4mm stepdown ferrule and put it on there.

5 to 4 step down ferrule. Thanks!

In principle, you shouldn't even need a ferrule on the chainstay end. However, on my previous 620, I found that the inset on the end of the chainstay wasn't so deep and that an unferruled cable end would get chewed up.
One of these might work:
https://www.loosescrews.com/index.cgi...id=24004169888
This is definitely one of those experiment around situations.
The other alternative is to forget the internal cable routing and use a clamp on chainstay stop.
Again, all this really only makes a functional difference in the index shifting case. Otherwise, it is just for appearance and clean finish.

On my frame with internal chainstay routing - but not a Trek so I don't know if designed differently - I stripped about 1" of the outer housing only down to the spiralling metal strands. Then I used a plastic ferrule and opened the end to the same diameter. The modified housing went throught the ferrule and then I inserted this package into the chainstay hole. It's working OK for index shifting, but I have had to tweak it some.
To route mine, as it didn't want to go easily the front way, so: I stuck a cable through the back way - slides easily down to the BB shell - taped the shift cable (with a small amount of tape) to this chaperone cable and pulled/pushed it back through. Was actually a pretty easy workaround. Let gravity be your friend when extracting - this will keep you from pulling the cables apart out from the tape.

Robatsu, what do you perceive the differences to be in terms of frame construction quality and ride characteristics between your 620 and say the 1983 Fuji IV and 1984 Fuji V?

Supposedly, Trek was continuing to silver braze their 531 frames through 1985 at least, not really sure if that makes any substantive difference. The Fuji has chromed fork crown and dropouts, I'm a sucker for that, Trek really never chromed much of anything back then anyhow.
I never put fenders on my Fuji V, but the clearances looked astounding IIRC - I've got 700x35 w/fenders on the Trek, that looks to be the max, which isn't bad, but it would be fun to try 37.
The Trek has an integrated headtube & lugs (with fake cutouts...), some may perceive this as cheaping out a bit, but I'm not sure what the motivation for that was and even if it was for economy if it has a good or bad effect.

When replacing the cable, I always solder the cable end to the new cable, then pull the new cable through the stay as I pull out the old. If I were to have to snake new wire in without having it tethered to the old cable, I would probably first snake through some stiffer wire, like solid-core picture wire, and use that to pull the cable through.
