Wow, that top tube is massive for that seat tube length. Or maybe it's just perspective. I don't think my mtb to drop bar conversion had that much difference.

Pretty normal for early MTBs. The Repack klunkerz were basically modified beach cruisers, and beach cruisers tend to have lots of backsweep on the bars which effectively "shortens" the top tube. Even after mountain bikes entered mass production, it took a while for the geometry to change.

Similarly, here's a profile view of my '84 Stumpjumper:



Although the top tube is huge, much of it is behind the bottom bracket; the actual stack and reach of the frame isn't too far off a road geometry for me. So by slamming the saddle forward on a zero-offset seatpost, I was able to do a road-ish fit without things getting very weird.

OK, I've only put drop bars on a late 80's Schwinn (many, many years ago) and an early 90's Mongoose (back when they were still a bike store brand), so maybe that was after geometries started changing a little bit (or maybe those were so long ago my memory is foggy).

1990 was NORBA era, MTB geometry got more road-like during that time. Since then, MTBs have moved back to very slack front ends, but the chainstays have remained short.

Ah, that could be, my Schwinn Woodlands was a 1989 and the Mongoose was probably a 92 or 93 at the latest. They worked ok for what they were and were a decent gateway drug.

It has been a while since I've posted but this 1987 Street Stomper - it has gone through several changes. Here she is with Compass - now Rene Herse - Rat Trap Pass tyres:



I believe the next iteration will include moustache bars and a front basket.

If memory serves correctly, they're origin8 bullhorn bars, not quite a drop bar, but to me, they're very comfortable

Dekerf? Really?

Sorry, if I had a Dekerf, I'd keep it as a MTB, but sub some slicks on a second pair of (good) rims. A very nice bike. I'm jealous.

No need to be sorry, what youd do with the bike isnt relevant to me. 🙂 It did a decent job of being a CX bike for a season (7 years ago!) before I bought my Cross-Check.

That one was great craftsmanship but too small and too beat up for me to keep. Its moved on to someone else, and is being adorned with period correct parts and gently ridden around town. I hope this meets with your approval. 😉

I'm just jealous. What's most important is that it is being used and thoroughly enjoyed. An my opinion should mean nothing to anybody else. It is a great bike.

Wanted to share an update on my Univega Alpina Uno conversion. I love this bike! Recently added the front basket and the Oury grips on the drops. Such a fun and versatile bike.

^ Nice Univega.
I also zip-tied the stretch net onto the basket on my town bike. It's amazing how much easier it is to deal with, having one side fixed.

Still a work in progress, and in the final shot next to my other work in progress!

But I think this will turn out to be a good candidate for a drop conversion.

Her she is... Long and Low. Looks to have a 24" top tube and I ride a road bike it a 22 1/2 top tube, so I need to find a 1 1/8 threaded BMX stem, if such things exist.

Try a threadless conversion and a super short stem. Thats the challenge with SOME of the vintage MTBs, really long top tubes. Its something to watch for as others can have more manageable length TT.

That should make a nice drop-bar conversion!

I've got few frames that I'd like to try with dirt drops, I figure I can sequentially build them up as single speeds and see how they ride with the same wheel-set and cockpit.


The dark hunter green paint on this one is realy nice, and dark enough I think I can do a good job touching up the dings and rust.

Stumpjumper 2.0 for gravel duty.
Lots of custom bits, front brake bridge and relocated brake mounts, relocated rear brake mounts,
custom adjustable rear derailleur cable attachment to mate Campy to Shimano.
Rebuilt fork, relaced old road race wheels. So far so good.

Not an MTB but a hybridI guess it counts. 1993 Marin Redwood, full 700CX, pretty darn light for its size and age. Climbs like a beast.
