Finally landed a genuine Multi-Track! Yesterday picked up this 1996 720 for $80. It was mostly all stock except the bars, stem, seat, and front brake. Bonus: came with new Specialized Nimbus Armadillo tires in 700x38c size!
Of course I couldn’t leave well enough alone so I stripped it down and got to rebuilding with stuff out of my parts bin:
Shimano 700CX rear derailleur
Shimano 700CX front derailleur, XT crankset 24/34/46, XT bottom bracket 68x116
Shimano 9 speed LX shifters, Avid speed dial brake levers, Kalloy UNO AL-030 bars, Strong 26.6 seatpost and a Bell Dart 500 saddle
Shimano 400CX hubs, 400CX cantilevers
Shimano 400CX hub re-spaced/re-dished with an 8/9 speed free hub body
Still need to find a 9 speed cassette and chain, and cable up the shifters. I would really have liked to find a 750 or even a 790 (good luck with that!), but I’m pretty excited with this one!

My '95 730 is mostly original when it comes to components. If I were ever to upgrade the drivetrain / wheels / brakes, I would want to do it the way you're doing it, with higher-spec-but-still-fairly-vintage parts that "look right" (IMHO) on the bike. You don't need my approval, but you have it!
I am always on the lookout, but my local market (at least, the places I've been looking) has not been producing many interesting bikes.

I wish that at the very least it had the mid fork braze-ons for low rider pannier mounts. The 400/700CX parts were only made for a couple of years in the early/mid-90’s. Mine are date coded 1994. The 700CX was supposedly Ultegra level stuff. So it’s pretty nice, but mostly I like the aesthetics of it. It all came off a Nishiki Optima hybrid I picked up several years ago but was too small. Unfortunately the shifters were toast but my local bicycle collective is pretty good. I regularly find pretty good stuff there... that’s why my parts bin is so well stocked!

Found this post over on MTBr.com forum about Shimanos 400 & 700CX groups:
There were two high-end Hybrid groups from shimano, the 400CX and 700CX and "hybrid" is funny since the CX designation just screams cyclocross to most folks. The 400CX was the "LX" level and the 700CX the "XT" level. They both used the corresponding levels of BB and the cassettes, 11-19 7 speed compact cassettes. The cranksets used an unusual 58/110 bolt pattern with 58mm 22T and 32T rings matched to a 110mm 42T ring. Those 11-19 cassettes were highly coveted among bike couriers as they were the tightest geared cassettes you could ever get from shimano at the time. Whoever did that spreadysheet was an idiot though as he constantly grouped the hybrid groups in with the mtb groups, and put the low end mtb groups in as "other" groups. Another plus to the 400CX/700CX derailleurs is that they're the only middle cage derailleurs you could get from shimano until the late 90s when the road triple groups started getting them, as did the Deore XT group. Before then only XTR had them and the hybrid groups.
Kind of interesting anyway...

I recently bought a 1991 lugged Trek 750 and a 1997 Trek 750. I have been cleaning them up, lubricating and adjusting the brakes etc. I would like to replace the brake pads. As best I can find out the 1991 with Dia Compe XCE takes Dia Compe OPC-12 brake pads and the 1997 with Shimano Alivio brakes takes Shimano BR-CT91. I am hoping someone on this forum can confirm the brake pads. Also I was trying to go to a website where I could put in what I have and bing up pops the information for replacement model. I could not find such a bike website. Help!
Curious, I put these two bikes next to each other and was very surprised that although they are both 19" models, the top tube is completely different in length and the angle attaches lower onto the seat tube. It's pretty noticeable. Awhile ago I posted a query about whether anyone had ridden a lugged Trek750 vs a welded Trek750, post lug. I was curious about whether they found a difference in the ride. Nobody responded. Once I get new brakes on the bikes and finish my cleaning and lubricating, I'll find out for myself.

I'd love to see the difference in pictures if you're able to post them. I have a '97 750 and have never ridden a lugged one. I think the '97 rides pretty nicely.

Trek 750 Chain Ring Size 1991 vs 1997
I plan to post pictures when I get more posts. Another thing I noticed, the 1991 has 48-38-28 for rings and the 1997 has 42-32-22. I have not checked the cog.

I've posted before but I've updated my Multitrack to drop bars...
Late 90's version...
3x7 speed, Matrix rims, flat bars, thumb shifters, plastic fenders...
2010's version...
3x9 speed, VO fenders, flat bars, battery operated lighting.
2020's version...
The changes were new stem, bars, brake levers, bottom bracket dyne, and stem shifters. Took it for a test ride yesterday in a 14 mph headwind. I think the drops are the way to go with this. I used a pair of NOS Suntour Sprint friction shifters. They are probably the smoothest shifters I have.

This is the 1992 790 I've been rambling on about. It came almost 100% stock from what I can tell. These images were taken after a good shine up and removing some things off of the frame like fenders, a kickstand, and a rear rack.
I have a few hundred miles on the frame now and have made a large number of component changes including a drop bar conversion. Here are some stats/thoughts that might be useful/interesting to others:
Bike details:
1992 Trek Multitrack 790, 21 inch frame.
Sizing:
I would say the 21 inch frame it is on the large end of fitting well. If I had to guess the 19 inch frame might be on the small end of fitting well. I am 5'9" with about a 30.5" inseam.
Weight:
26lbs as pictured (stock)
Wheel spacing:
Front: 100mm Quick Release
Rear: 135mm Quick Release
Side note: I am using a 10 speed 130mm rear wheel right now on the frame and it seems to be running fine. I may try to have a custom wheelset built around the original spacing of 100/135.
Tire clearance:
With fenders: I would guess max width to be around 35mm with fenders. Go with 32mm to be safe.
Without fenders: I have a pair of semi slick 38mm tires on the bike now with clearance for more (but no clearance for fenders). I will likely attempt to fit a pair of more aggressive ~40mm tires at some point for more heavy duty trails/gravel. I doubt anything more than ~44mm will fit.
Seatpost Diameter:
26.6mm
Ride Quality:
Great

Updated pic of my 730 MT . Had to lose the rear rack to swap out the rear cantilever brakes for Shimano V-brakes . I was worried the V-brakes wouldn’t be much of an improvement on the old wheels . No Problem , the V-brakes are soooo much better than the cantis .
This is the lightest bike I own .

This 730 from 1998 (I think) showed up on my local CL over the weekend and at $40 it seemed like a good deal so I bought it to use as a starting point for a drop-bar conversion. I'm more excited about the project aspect than any particular bike use. It's a 17" which is a little too small for me as is (I'm 5'8"), but I'm hoping will be about right with the additional reach of a drop bar. For comparison I have a 18" 930 that's about right with a flat bar, although the 930 has more aggressive geometry.
What should I do with it?

Ride it, see how it feels. You'll definitely need to change out that "saddle" and probably the seat post. After that, your best bet is to check out the C&V mtb. to drop bar conversion thread. Good luck, have fun, and take lots of pics!

It's a Profile Design 1" to 1 1/8" (https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1). Upanbike also sells one on Amazon. I covered the exposed part with spacers. I couldn't find spacers with a 7/8" internal diameter so I had to rig some shims to fill the space.

I posted a picture of this 1995 730 about seven months ago, but I'm posting new ones because it has seen some changes since then:
- Topeak Super Tourist DX rear rack; home-built bracket to mount a pair of CatEye reflectors without interfering with the taillight mount.
- Shimano PD-T8000 pedals (hybrid SPD/platform).
- Replaced the headset with a Tange-Seiki Levin CDS.
- Replaced the original lever-action seatpost collar with a Salsa Lip-Lock.
- Sella Anatomica X2 saddle.

Anyone have problems with ovalized head tubes? I took my lugged 750 on what I thought were pretty mild trails and ended up with an ovalized head tube anyway. Maybe should have installed a new headset instead of the old stock one and ran tires thicker than 35mm...
I thought the wheels would be the weak point and the frame would handle trails basically the same as a Singletrack frame... doesn't seem to be the case.

The Chris King Steelset has a deeper insertion than normal headsets- you might be able to get enough purchase in the still-round section; Chris King also used to provide oversize cups upon request. Both of these options require expensive facing and reaming tools and the headsets are expensive but if you want a possible solution, those are two. FWIW I have a 1" King headset I purchased in '93 for $100 thats still in use and could be resold for at least that.
