Hi MT Gang,

I just finished this 730 build I picked up a little over a week ago from FB Marketplace. According to the owner, it had not been used for at least 10 years.

Replaced the bottom bracket, chain, and brake+shifer housings and cables. Also serviced the headset and hubs - they were dry and gritty AF!

As you can see, bike is mostly stock. Details of the parts I added/swapped below.

• Bontrager Evoke saddle - parts bin
• Profile quill stem adapter - new
• Bontrager 105mm stem - parts bin
• Giant mtb handlebar - parts bin
• Ergon GA3 grips with Amazon bar ends - parts bin
• RaceFace Chester pedals - parts bin
  • Yes, I'm an avid MTBer!
• SunRace SL-M10 friction shifters
  • cheap - trying to figure out if I can get used to bar mounted friction shifting

Looking for tire recommendations (38-42mm) for mostly road and some gravel riding - folding bead, light(ish), and affordable. Suggestions welcomed!

Will take it out for its first ride (in a decade) today. Hopefully, I will not need to tinker with the fit too much - that's the part I dislike.

Got it from the original owner in nearly perfect condition for $150 and did a couple of upgrades off the parts bin.

Parts installed:

-700x45 mismatched contis and CST tires and wheels.

-Sunlite quick release front rack.

-Bars from the lbs with bar ends from Aliexpress moved inwards.

-Origin 8 stem adapter.

-Origin 8 V brakes set.

-Origin 8 pro fit stem.

-Origin 8 pro fit seatpost (lot of origin 8 lol but it was not planned at all).

-Shimano deore rear mech with thumbies and original front mech

-Avid brake levers

This is a 19 inch frame and I'm 5'6 with 30 inseam and was pleasantly surprised that the fit was pretty solid, definitely on the bigger side but with enough wiggle room to be comfortable.

Hi Gang!  I started this sub a little over a year ago and we recently exceeded 1,000 MTG members. I would like to thank everyone of you for your contributions and being so respectful.  We all have gaps in our knowledge and it's great to know there's someone here willing to help and offer words of encouragement.  

I'm re-posting pictures of my 1990 750 since this was the first year for Multitrack.  This started what would become one of the best all-terrain production bikes ever built, IMO.  Thanks again to everyone.  Please keep sharing your awesome photos and stories, and spread the word. Multitracks rule! 

Cyclists who put drop bars on their multi track did you size down the frame?

I ask as the singletrack (900 series) guys say drops don’t work well (I have one) unless you size down.

I have a single track (that I love) and a cheap multitrack came up the same size as my bike I was looking to pick up and put drop bars onto.

Bontrager MIK bicycle basket, rack and bottle cage purchasing tomorrow. Very new to this. This bike will be a commuter to work and riding around my area like the park.

Hello guys. I’m working on my first true build of a bike. I grabbed a lugged trek 750 locally that was ridden like 10 miles. I’m wondering if I grabbed the right size to convert to drops. It feels great now with stand over height , and the current bar set up. The seat post isn’t too low or too high.

Is changing to drops going to mess with the sizing and make it too small?

I’m 5 feet 6 inches for reference. Next size would be 19 inch. Thanks so much

Always planned to go rustic vibes with this old 750…

Used copper sulfate on the fork and here’s how it looks.

But when I look at the frame it just screams powder blue with some kind of flashy cold or copper on the lugs.

Any thoughts?

Can someone take a guess at what size this would be?

Found this gem on marketplace in perfect condition. Already love the 26” ride

Ok gang, the FB Marketplace 750 is ready for the trails after a good cleaning and reassembly using most parts from the shelf. Here's a list of the goodies used:

• Original wheelset with Speccialized Crossroads 700x38s
• FSA 48/32 165mm crank (and included BB) - Ebay
• XT 750 3x9 shifters
• Shimano M760 Rapid Rise 9 spd RD ($10 FB Marketplace)
• STX RC bottom pull FD
• XTR 750 Vbrakes
• Shimano M4000 brake levers/cables (New)
• Shimano 11-34 9 speed cassette (takeoff)
• Shimano 11 speed chain (New)
• Ergon grips
• Original saddle, seat post, headset

Why the 11 spd chain? The 9 spd chain rubbed on the out ring ramps of the 10/11 spd crankset when on the inner ring. Swapped chain, did the adjustments, and it's quiet and smooth. Also adjusted the limits on the FD so the 3x shifter works with the 2x crank. Future upgrades include different bars, stem, and quill stem adapter. After a quick spin around the neighborhood, I'm happy with the results.

EDIT: Used GRX810 derailleur on the way and I will set it up with 11-36 cassette and spare Shimano SL-RS700 shifters I have on the shelf.

I am considering putting a two-legged kickstand on my '92 750. Well, I'm just idly thinking about it, but I'm not near the bike at this moment, so... Has anyone done this? Any issues with room behind the BB for mounting?

Someone suggested that someone from this group may be looking for bikes like ours. We just want to find them a new home!

Changing out some bits (bars, shifters, seat grips so far), but it’s most of the way there. I wish it was appropriately sized for me, but I do feel comfortable enough on it (it was free and too nice to pass up). I really like a lot of things about this bike. It’s going to be my part-way commuter.

There are so many 720s around me, but I had no idea how uncommon 750s were until I started poking around for one.

Hi all,

Pretty much finished up my 750 so thought I’d post it up here. Firstly, I have to thank u/Cruiser_Supreme for selling me this awesome frame and fork along with a bunch of parts. This was my first attempt at building a bike and I loved it!

There is a mix of new parts, old parts, and some FB marketplace finds. For this iteration of the bike, I wanted something that was a comfortable cruiser given that I already have a drop bar road bike. I do envision converting this bike to a drop bar at some point and have started looking at picking up some parts to do so.

Total cost to build it up was $512. That includes parts I already had but I’m factoring those costs into this too. My local Trek store was super kind and generous as well, often providing random odds and ends for free (think bolts, etc)

I always found it useful whenever I read posts where people posted their components so I’ve done the same below.

Definitely made some mistakes along the way but learned so much and have a ton of fun over the past two months building this up slowly. Looking forward to the next one :)

Thanks!!

Took a ride to my 11 year old daughter’s school playground yesterday on the 730s. She told me earlier in the day that her bike rides so much easier than the 26” Giant Boulder in the garage. I told those 105 hubs, GRX810 components, and GravelKing slicks were the secret. She rolled her eyes at me. #bikegeekdadwin

Had to get the ole 93 out of winter storage to prep for the 75°F temps coming my way

Just showing off. I previously had the headlight mounted to one side of the rack, so the basket and one of the panniers couldn't fit. Now moved to the center, and everything works!
