I've got a '90 750. Great versatile frame with the same geometry as the 520. I've had mine built with drops and more recently as a city bike. Currently switching it back to drops with a compact double.

That is a great looking 750. Can you tell me what brakes and shifters that you were using as a drop bar bike?

Thanks. The brakes were Tektro RX5 Mini V and the shifters that I used were DA 9 speed bar ends with Paul Thumbies.

Does the 91 Trek 750 Multitrack use a 22.2mm or 1 1/8" quill stem?

Is the rear axle diameter 130mm or 135mm ?

My 94 750 uses a 22.2 stem. I have also discovered in 94 only, shimano stx used a 95 bcd crankset, and if you were considering putting a set of clamp-on downtube shifters on, the downtube is not standard road bike diameter but instead something like 33.1 mm.

Related, I am now in possession of a brand new, unused set of sunrace clamp on downtube shifters.

Very nice find! I was looking for something like that a few years ago for rail trail type touring. Hybrids with the mid fork rack bosses are hard to find. I wound up with this Univega Via Carissma (fenders added later) which worked out well for me but would have preferred a nice lugged Trek like yours. Enjoy.

Don't ask me how I ruined the crankset to my 750. What is the exact replacement?
Where might I find one.?

I thought about using a Sugino triple, but I like this combination of black rings and chrome spider.

What other alternatives would not cost an arm and a leg?

Threaded BB shell so you can put in pretty much anything you want. If the square taper BB is still good then any road triple should work, although watch the clearance between the chainstays and the inner rings. If you need to replace the BB just make sure you get one with a long enough spindle for a triple (unless you want to swap to a double. In which case you'll have to change your shifter.)

According to the 1991 catalog on vintage trek, Vintage Trek Bicycle Catalogs and Bike Brochures, Fisher, Klein LeMond, this came stock with a SR XCE crankset. Finding that exact crankset will likely be more trouble than it's worth, and it's not like they offer any advantages over any other crank. I can't find any specs but I'd assume it's a 74 BCD chainring because that seems to be what they used on MTB cranks back in the day. Someone else might have better info than me.

I won't ask, but I am pretty sure I have done the same thing. Or at least equivalent on the bonehead scale.

Today I won a Suntour XCE crankset on the auction site. What size bottom bracket should I use?

I would like to find an original type Tange bottom bracket with seperate cups and spindle. I may have to go with a cartridge type.

68mm bottom bracket, but I have no idea what length spindle. A few minutes of googling did not turn up the answer, although I've seen a couple forum posts that suggest anywhere from 122 to 127mm spindle. Any chance you can measure the old one?

At $20 I'd probably just throw a Shimano UN-55 in there with a 122.5 spindle and hope for the best; it will last for years and you'll never have to think about it.

ksryder,
Thanks for your suggestion. I sought the help of my favorite LBS to free my old spindle from my ruined left side crank. They were able to get it loose in just a few minutes. I am pleased that I will be able to use my original bottom bracket. It has a 123 mm spindle.
My replacement crankset should be here day after tomorrow. I let this bike languish for 2 1/2 years in disillusionment over ruining the left side crank. Before doing that I did manage to renew the wheel bearings and mount a set of Panaracer Paselas. I hope to get this bike up and running again soon. I keep thinking about chang ing to drop bars. Does this bike have a 1 1/8" stem?

Nice score, congratulations! I have never seen so much love from C&Vers for a Trek MultiTrack.

IMHO, the mid 1990's Trek Multitracks, whether 700, 730, 750 are underrated for desirability as a commuter or utility bike. The frames are sweet and the drivetrain parts are cheap and easy to upgrade.

Even more underrated is the mid 1990's Trek 850 Single Track, the spec equivalent to your MT 750, and very similiar to a Single Track 930.

I just picked up one of these from the Bikeworks warehouse sale! And it was even already converted to drop bars. If anyone spins up that hybrid w/ drop bars thread, I'll post it there. Just found a wheelset for it so it should be ready to roll soon.

Nice thread, guys. I've also got a Multitrack that I repainted sitting on my workbench in the garage right now. State tax return= finally finishing the drop bar conversion. Yay!
(And I will track down the hybrid conversion thread when it's finished, too.)

Here's my 790 with a set of Midge bars I added. I sold it years ago when I was having hip problems. Kinda regret it now.

This Vintage hybrids? Maybe not so bad after all... is the C&V show me your hybrid thread. I don't think there was a specific hybrid conversion thread as most just got posted in the mountain bike conversion thread.

Hybrids are fun to convert because they are so cheap to begin with and can take most anything you choose to do.

I cleaned and installed my original bottom bracket today. I also installed a black Brooks Flyer in place of the ugly torn saddle it came with. Trying to decide what to do about pedals. Hopefully, the replacement crankset will arrive tomorrow. I have a new chain to use.

Which Trek steel hybrid frameset is the ultimate in lightness and geometry?

The rear shouldn't work indexed of course. I've got nice condition 7 speed Accushift barcons if you're looking to go that route. PM if interested.

I received my replacement Suntour XCE crankset and installed it along with some Wellgo WR-1 pedals. I had a hard time getting the placement right on the front derailleur but finally it settled into a happy place. The X-Press shifters were hard to move so I degreased them with solvent and lubricated it with Blaster with Teflon. Replaced the front derailleur cable and with minor adjustments shifting was perfect. It is now totally stock except for the Brook's Flyer, Pasela tires and the rear rack and rear bag.

I went for a short ride today and it was great.The Paselas gave a smooth ride and it tracked straight and true. It is a little big for me at a standstill. I can stand flat footed with a lot of contact. While riding it has the "French Fit" that I prefer. I noticed a lack of braking power from the 25 year old DiaCompe XCE canti pads. Does Kool Stop make a replacement for the splined shaft DiaCompe brake shoes?

This thread got me looking...

https://charlotte.craigslist.org/bik/5998067122.html

Not my size by any means, It's close to my fiancee's size, but she has a bike that fit's this role currently.
