are those spenco bar and brake grips? That's a serious blast from the past. Did the bike come with a skid lid as well?

Great find; appears to be a real time capsule with original tires, even! I've got the same wheel set, in pristine, black anodized condition, if you're interested. Been looking for an appropriate Trek touring frame for them, but so far, no luck.

That may be Trek's best 20th century touring bike. They used to claim that the 22.5" and larger frames were made with Reynolds 531 Special Touring ( heavy gauge top and down tube, 1.0/.7/1.0mm walls.). Only drawback is narrow spacing of cantilever bosses; the frame is "good enough" for any components ever made but your brake selection will be pretty limited.

Congratulations!

Yours is an 85 model year- all the 85s were brazed in 84. The big tell is the 84 model year decal scheme had the model number on the downtube "Trek 720," the 85s just had "Trek."

Tube set is slightly different as are the components (and wheelbase).

Due to poor customer demand for touring bikes, Trek used all the leftover frames from '84, updated with current graphics when they painted them, and sold them as '85's.

Nesteel covered it-

The Trek 720 had different frames in both 82 and 83- There's a few minor differences in components- but the frames for 84 and 85 Trek 720 are completely the same- HOWEVER- there are differences in some 84 and 85 frames- notably the number of eyelets on the front fork ends. Some have 2, some have 4. I've seen some of each decaled as both 84s and 85s. I prefer the 85 decal scheme, but I think the Sugino AT from the 84 is a better crankset than the LP from the 85.

The differences between the 620 and 720 are numerous- first- the 620 was a different bike every year, and even in 85- where the bikes were the most similar- they were still entirely different bikes- different components, different tube sets, different angles, different construction method- and the back half of the bike was assembled in Japan and final assembly was in Waterloo. I have an 85 620 and an 85 720, they're both REALLY REALLY good bikes.

were they Panaracer T radial tires with green label? from wikipedia: Radial tires have occasionally found application on bicycles, used on the 1980s Miyata touring bicycle; models 1000 and 610,[19] and more recently in 2009 on the Maxxis Radiale.[20] Panaracer radial tires were also standard on the Jamis Gentry model bicycle in 1985.

I don't see the narrow canti boss spacing as a problem, big tires seem to fit right in and the narrower spacing reduces pad dive, making the switch to 700c rims less problematic in that sense.

The stock M700 brake pads were low-performing even when new. The "TT Radial" tires ruined the handling, even when I had the last one mounted on the rear.
Finally getting rid of that tire brought out pleasant handling manners, and the Cadillac ride qualities of the long frame made it a good commuter.

You can see if you like radial tires- they seem to have “unique handling properties” from what I’ve read. I have a set of National Duals from 85/86 in “like new” condition- I wouldn’t trust them much, despite their condition.

The narrow boss spacing causes problems for most modern cantilevers to adjust that low. Where brakes like the M700 MC70 or the M732 work fine, the Tektro CR720 won’t work (according to people’s accounts).

wow, you must be a strong rider. my 620 seems to be built like a Tank, of course i don't max out any of my bikes...just ride and enjoy.

hope your bike hangs in there for some more decades.
