Work in progress, but my 2x7 to 1x10 is already done

Up next: shorter stem, bartape, and in the longer term a paint job
This will be my winter-gravelbike.

lookin good !

Good work! A good mix of the old and the new. I used the same threaded to threadless stem adapter and it works pretty well IMHO. I've also switched back and forth between flat bars and drop bars. I also did the 1x10 conversion with updated wheels. I look forward to seeing any other mods that you make.

Just finished the clean and tune on this 750. Such solid well riding bikes.

Beautiful! A '95 model, if I'm not mistaken, brandenjs ?

Got this Multitrack in a trade a few days ago. I think I’ll put some 105 shifters on it instead of the bar ends.

The stock config on all the Multitracks I have seen is either riser bars or flat bars with grip shifters or trigger shifters.

Would anyone know what's the chain line on MultiTracks? 1991 750 in particular. Looking to get a new crankset for mine.

I wanted to share some photos of my 750 but I cannot post with photos still

Nice finds! I am quite jelly!

How do you find these fresh Multitracks in FB marketplace? Is there a specific word you include when searching?

All I could find are really beat up or maybe it depends on the location.

nivekelyk

Thanks! I'm located on the side of the world. I have sent a few bikes to a relative in the US and then shipped them to me. And yes, I've been searching through FB marketplace from time to time. Hehe, I am really just trying my luck here.

That one in particular was a lucky find. The others I've gotten have generally been in a little bit rougher shape. There's no trick beyond brute force, not that I've found for FB marketplace at least. I'll search "trek 750", "trek 790", "trek multitrack", and "trek touring". I also look out for the 520's of that era as they're the same geometry, have lighter tubing, and an extra bottle mount on the bottom of the down tube.


I recently built up this mongrel; a 520 frame with a 790 fork that had eyelets brazed on. It now has grips, a black Brooks Flyer, and a matching set of 700x43c Gravelking SS's. Currently installing some Velo Orange Zeppelin fenders, but I need to trim the rear fender where it meets the chainstay bridge to get clearance.

Hello all, my 90, 750 will fit 45mm front and rear, probably larger.

Question; do all steel MT frames fit tires of 45 wide without fenders?

Thanks Ruben in So Cal

My '96 720 will fit 45's with loads of clearance...

No. Anytime the question is does everything do the same thing, the answer is generally no. Fitment is something best left to the actual bike and testing. They could have changed something year to year for whatever reason or that frame could have come out differently and won't fit certain things for certain reasons or whatever. Also probably more so tires are different one tire might be a 26x2.0 and another might be a 26x2.0 and one measure 2mm or more wider or narrower or maybe one bike has wider rims or narrower rims...

Basically check your frame or a frame you wish to purchase and go from there. Generally if it is the same year and model likely it will have the same clearance at least for the middle and larger sizes sometimes smaller sizes might run into some issues not always but sometimes. Measure twice cut once!

The simple answer is no. I have a 1997 MT 750 and I might could squeeze a 45mm tire in there without fenders, but it'd be very tight. A 42mm would be tight. It'll comfortably run 38s or 40s but much larger than that is more difficult. It's also more than raw frame clearance. If I fit wider than a 38mm tire on my MT, I have to deflate the tires to remove the wheels to clear the front brake pads. You can get special short-style pads to help clear fork blades, but it's definitely a consideration (brake pad clearance).

After thinking more about the frame clearance I really have on my '97 750, and seeing just what actually would fit, I dismounted the 35s I had on it and tried something larger. Much larger. I have a set of 29x2.0" first generation Schwalbe Hurricane tires from a previous bike in my tire pile, so I dragged those out to see if they'd fit. On my 750's rims (which are only about 15 or 16mm internal width), the tire casing/carcass itself measures about 44 or 45mm wide and tall, though the cosmetic knobs on the side do push the overall width to an actual 50mm. But as far as the tire height goes, it's about 45mm above the rim edge...so likely similar to a 45mm tire that actually measures 45mm.

They did fit in the bike...like...barely. I did have to have them mostly deflated to slide them up between the brake pads, but they do fit, and actually ride pretty nicely. Traditional fenders would not fit on this bike. The clearance is tightest down at the seat stay bridge near the bottom bracket (and front derailer area), and there's not enough room to fit fender mounting hardware down there (with the tire in place). The brakes are Tektro Mini-Vs (to work with the factory short-pull levers), and the brake cable yoke just barely clears the tires...there'd be no problem here with longer brake arms or with cantilever brakes.

Pictures below. Again, except for the side knobs, these are basically 45mm tires.

I have a 1992 750 MT. What @hokiefyd says above is pretty much the same experience on my bike.

Here is my mid-90s 750. Just a fantastic bicycle, rides so smooth. Looked everywhere for some mx style handlebars, and something that would work with a 31.8 stem. Then I found a pic and the owner graciously responded back and said that they were Cannondal Cruise Control bars. Finally found a pair a few months back and it has improved the ride quite a bit.

I've been trying hard not to pick up more bikes but I couldn't turn down this pristine Trek 750 when it popped up last fall at $125. I stuck it in the garage and pulled it out recently to take a few pictures. I haven't decided on the build yet but I'm strongly leaning towards trekking bars. They're comfy and versatile.

This is how the bike came to me in the wild. Bit of an odd set up with the drops and thumb shifters but otherwise the bike is pretty much all original. I picked up a set of Schwalbe 700 x 38c green guard tires to turn this into a trail and gravel bike. I plan on bringing it along on car camping trips in the summer and I wanted stout tires especially for riding out west where the goat heads are plentiful.

The cantilevers will need to go but I may keep all the other parts other than the pedals. They're not top of the line Shimano parts but they work fine and the cost is right. I've overhauled the wheels and they're in great shape. I need to overhaul the headset and replace consumables. I'm a big fan of Treks and this is my 5th (!) lugged steel Trek (3 road bikes and a 1992 950).

I'll pick up a set of MKS Allways pedals. They're a little pricey but MKS makes great pedals and this is a good design. I'm not sure what I'll get for cantilevers. I really like the Tektro CR720 cantilevers; they're cheap and they work great but it looks like Tektro has discontinued them. I suspect I'll hunt around the parts bin and go with what I have on hand.

Korina

@bikemig, I like the Tektro Oryx's on my RockHopper; they stop the bike and look stylish doing it.

Maybe I should clean it before making pictures next time
My winter bike ...

DorkDisk

Winter is long over here in NY; was a very mild one overall. Time to put the winter bike away. Here you can kinda see the full length liners on all the cables, which have done a great job of keeping the cables clean.

Just finished fixing up this 750. I think this one is from around 1991ish from the component date codes. It looked like heck when I got it, but it cleaned up nicely. Full Suntour XCE, except it came to me with a set of thoroughly trashed Grip-Shifts. The cleanup & rebuild went fine until selecting replacement shifters - the Accushift cassette would not play well with the Rapidfire or GripShifts I tried on it, and I had to break into my Emergency Strategic Component Reserve and commit a set of XC Pro thumbies to it in order to get decent shifting.


Update: I swapped the XC Pro thumbies for a pair of refurbished X-Press shifters, which worked fine; however, the bike has gone on to a new home as a bike for a local teen who is a friend of a friend. I hope it does well for many years to come.

Nice bike, I have the identical one but in a 23 inch frame, it's my official touring bike. It is an official 1992 model. I like the blue tires.

I put my MultiTrack 730 back together today and took it for a short spin around the neighborhood.
probably the lightest bike I own .
