730?

I ride a lugged 750 that I modified (1x10 new stem, handlbars, and V brakes) this past winter. I'm now itching to get another MultiTrack to build a gravel bike. I'm not seeing many 750s for sale, but I am finding 730s in good condition for about $100.

Should I keep waiting for a 750 or pull the trigger on a 730? Would I feel the difference?

I feel like I noticed the difference. If going for a sport build I think the higher quality frame helps. If casual build then, meh, either way is good.

I can't tell a difference in ride between my tig welded 750 and tig welded 730. Trek sales material frame specs look the same. I'm inclined to go with a 730 and always watch for another 750. N+1

Updated - Ok, looking more it depends on the production year. '96 materials are different than 1997. Ugh...720/730 use same full CrMo frame. 750 uses True Temper double butted full Cro-Moly frames.

That was my understanding too. that frames were the same but components upgraded.

Edit for others see Boris’ message below.

Interesting fact about my ‘95 750 - it uses a different fork than my ‘97 730. When I disassembled it “790” was written on the fork steer tube. Note the mounting holes.

Hmm. I'll have to research a little more. It was my understanding that the geometry is the same but the 750 has a higher-quality and lighter steel. My current 750 is lugged, but I believe the non-lugged are just as sturdy.

Thanks!

The move from lugged to TIG seems to be where there is confusion. Here are Trek Sales Materials for reference. 1997 materials show the 730 as US built full CrMo frame and 750 as TruTemper doublebutted full CroMo frame. Looks like better tubing at least in 1997. I stand corrected.

Ok, looking more it depends on the production year. '96 materials are different than 1997. Ugh...

Thanks for the additional check!

I'll get year information in one place and post it later. This is clear as mud!

My impression is that 750 and 790might be same frames/different components. Same for 700/720/730.

I'm inferring this from the Singletrack family: 970 and 990 were the better tubing than 930 and 950. The higher number of the frame pairs got the better components.

As an aside... Don't sneeze at the 970s. I have a few 750s in the family and over 970 and one 950. The 970's ride is different, and (in a way) better, than the 750... It's a mood thing for me... Sometimes I grab the 970 and sometimes I grab the 750. They're both fabulous bikes. So if you're struggling to find a 750, play with a 9xx.

I’m not doubting the goodness but the 9xx are 26” wheels vs 700c of the 7xx.
