Hybrid bikes from 20 odd years ago came in many flavors, some with dreaded front suspension or super upright riding positions but there were also many "sporty" ones whose geometry more resembled road bikes albeit with longer top tubes.
By now, there are a ton of these bikes on the second hand market and they are largely forgotten and cheap, particularly if they need some work to get going again and as they are now old, many sellers are unaware of the quality level of the various models so bargains abound. And some of these had decent components like Deore XT or Ultegra gearing, CrMo or decent Aluminium frames, Carbon forks and threadless stems etc.
It would seem these would make ideal bikes to make a budget drop-bar conversion gravel bike. Throw on a pair of drop bars, some old shifters or cheap Chinese ones, perhaps change the brakes to mini V brakes, new tires (most will take 40mm tires) and you've got gravel on a budget. A search of this shows some people have done the conversions but it seems there is way more interest in converting old MTB bikes to 700c wheels or even old 27" to 700 conversion.
Below are some of the models I think would work.
Felt SR 51, 71 or high end 81
Giant CRX series. CRX 4 is low end and CRX1 high end.
Jamis Coda series. Sport or high end Comp.
Trek 7700 series.

So why not?

I've thought the same for years, though I did it the other way around back in the late '80's. I cobbled an off-road bike together using a Schwinn sport touring road bike, to which I added flat bars and tubular wheels with Barum cyclocross tires. I rode it on fire roads mostly, but some single track, too.

That was a fun bike. It was two years later (I think) that Bianchi came out with the first commercially available hybrids. (Unless Specialized's Rock Combo---26" knobbies, drop bars---was first.)

An alternative to doing fairly complicated drop-bar conversions of hybrids: ride those hybrids as is. The bike I've done the most miles on for years now is a 1995 Cannondale H200 hybrid, which I kept stock, other than installing a front rack, fenders, and bolt-on aero bars, which I prefer to drops.

The aero bars make the bike faster on pavement and smooth gravel than it'd be with drops, and flat bars obviously work at least as well as drops on rougher surfaces. I also prefer the flat bars for riding through Baltimore traffic on my way to the roads and trails out in Baltimore County.

I think it's because no one wants to put hundreds of dollars worth of components on a bike that is worth dozens of dollars.

The experience of riding it with cheap components will not be satisfying to most BF members.

The higher end hybrids you're talking about had better components, so maybe rather than having to buy brifters, get one of the drop bars that accept flat bar components. (I think VeloOrange & Surly make them?)

It's a good idea, though.

Even without changing bars, adding bullhorn grips and/or a bit more aggressive stem would change the character of the bike for not much money.

Here’s one I converted recently:


Hybrids often don’t have ideal geometry for this, as they tend to have long top tubes and low cockpits by modern standards, being designed around flat bars. Same reason converting mountain bikes can be a challenge. Though here’s one of those I did:


Had to get kind of creative in both cases to get the handlebar in a comfortable spot.

There are a remarkable number of threads in C&V on doing exactly what the OP proposes. There are threads on converting rigid MTBs to drop bars, threads on converting hybrids to drop bars (which tends to be somewhat easier given the geometry), threads on 650b conversions for older road bikes, and threads on road bikes that can take fairly fat tires. These conversions are done to make some sort of an all road bike. If you're willing to ride tubulars (see the post 2), then a lot of bikes can do the job.

This is my 1993 Trek 750. I had planned on using drops but then decided to use trekking or butterfly bars. The bars give me multiple hand positions which I like. It's also inexpensive since you don't have to buy or scrounge around for new parts such as brake levers and shifters.

I have a 1992 Stumpjumper that I converted to drops and I use it on the local single track which is not too technical.

There are a lot of youtube videos of people converting hybrids and MTBs into drop bars. Converting a flat bar bike into drop bars is a hit or miss process. It can work on some bikes and not work on others. Dialing in a fit requires experimenting with different stems. Having a steer tube uncut and using a 35 degree stem seems to work on some frames which were not designef for drop bars.

I did one with a Schwinn Crosspoint. Using a very short stem countered the long-ish reach very well. I used it for some local gravel rides and in our fall cyclocross series this year. Nitto drop bars, Tricolor levers, old Dura Ace shifters, mostly Deore LX everything else. Ended up as a 3x with a tubular wheelset instead of what’s pictured here. Those are 35mm Gravel Kings in the photo. There’s room for a lot more rubber.

I did just find an old cantilevered Kona Jake for CX and plan to send this down the road though. It’s a fun bike and I’ll be a little sad to see it go. Per [sous-sol] (this was meant to say "spousal") agreement I’ve got to keep a static N at the moment, ha.

I have posted about it elsewhere on the forum, so apologies if you’re tired of seeing the dang thing.

Not sure how the geo stacks up on other Schwinn “Cross” bike models, but I wouldn’t hesitate to recommend for conversion if they’re the same as the Crosspoint.

They are out there, but it's like "Look at my supped up Corolla, ain't she great?"

I think people are starting to do so more and more. I've seen a lot more conversions with bikes with Cross somewhere in the model name in the last year.
I can think of a couple of reasons why:

• Old Stumpy frames continue to be coveted, to the point where Hard Rock frames are getting snapped up. Some early Crossroads have the same style graphics.
• Tire selection for 26 inch bikes is still pretty bad, but there's tons of 700c 35 tires to choose from.
• Tastes are changing. Drop bar conversions aren't practical. The reach on most old mtb frames are too long for it to work. People do it because it looks cool. People didn't think the Specialized Crossroads was a cool frame, so why would you spend the time and money on a conversion? It seems like that's changing.

How many do you want?

There are a quite a few number of vintage enthusiasts that prefer their vintage bike to be equipped as was original or as close as possible. So that probably leaves less vintage enthusiasts that wish to modify a hybrid vintage bike compared to the other cyclist that will just go out and buy what's actually made during the last decade and a half as a drop bar gravel bike.

I was thinking along the same lines but lucked into a CX frame that took at least 40's so I used it. It was a way better platform than an a hybrid.

And that may be the answer to your question. Before someone goes to the trouble of sourcing all the parts and doing the build, they are going to look pretty close at what frames are available. I think in most cases, the hybrid just falls short compared to the vintage MTB or CX options.

It’s a dirty little secret but a “hybrid” was meant to be something that could be used off-road or on-road instead of a mountain bike. “Gravel bikes” are really just tarted up hybrids. Go ahead and build one of those up. You’ll shock and horrify the gravel crowd because how could you possibly ride a death trap like one of those…they don’t even have disc brakes!!! You are going to die!

But who needs a Bugatti to go to the grocery store?

Maybe some of those older frames haven't lasted the test of time or maybe some people haven't found anything to work with nearby where they live? I don't know, I'm just speculating. Still it seems to be a pretty fun idea. Good projects for those that don't want to purchase a brand new gravel bike.

There are plenty of them but I would just get a drop bar bike these days. Nothing wrong with a conversion if that is your thing but I am unlikely to want that when I can get a modern bike with more tire clearance or modern geometry designed around drop bars.

It’s happening more than most people think. Perhaps I notice it more because I’m involved with two different co-ops but there are a lot of people doing the conversion that bluehills3149 is talking about above. I don’t personally have a “gravel bike” but I have two touring bikes that have done more gravel than most gravel bikes have done. If you stick with old 9 speed components, it’s also very cheap to build with used parts.

There are two technical reasons why this conversion doesn't work too well:
1. the aforementioned long top tube
2. A lot of these bikes came from the factory with MTB groupsets. MTB front derailleurs don't work with road brifters, and MTB cranksets don't work well with road front derailleurs.

That reminds me of a story...

I was in my local area on a singlespeed MTB I had put together from a 1999 Trek 9900 (26" wheels, v-brakes). It was a lot of fun. Chatting with some younger folks on their new, big, squishy bikes, I indicated that I was planning to ride down the same fun, challenging, singletrack descent that they were. They questioned my decision and wished for my safety because of my old bike with old brakes. They seemed very confused when I told them that we used to ride that same trail on fully-rigid bikes with cantilevers, and somehow, we all survived. I'm pretty sure they brushed it off as an old guy who doesn't know anything.

That said, my current Trek Supercaliber is a fantastic machine on that trail.

Didn't you get the memo? Gravel bikes are all 1x now.

(Yes, I know that they aren't all 1x.)

1.) No disc brakes
2.) 2x or 3x chainring
3.) I might die.

1.) No disc brakes
2.) 2x or 3x chainring
3.) Too old of a bike
4.) I might die.

I'm not really interested, but it's filtered across my awareness that 'Gravel Bikes' have larger section tires than 'Road Bikes'. 40mm at a minimum, and usually 45, 47, even 50mm. What HYBRID allows for that kind of tire selection??? None. Hybrids to a one design around 32mm rubber, and of course people get 35mm and more into them but that's not a real 'Gravel Bike'. So a HYBRID cannot be the practical donor for a proper 'Gravel Bike'. A legacy MTB can be, and while I was skimming this thread, I saw a couple of exactly that kind of conversion. More work because you are doing way more than a wheelset and tire swap. But the question as asked in the title answered itself IMO. Even a non-cyclist would have known the answer.

My first gravel bike was a drop bar conversion of an early 90s Univega Via Activa hybrid.
To keep the price down, I kept it 3x7 and used bar end shifters.
Some good brakes, a nice bar, and some 40mm tires were enough to help me sort out what I wanted in a proper gravel bike that fit more correctly.

My brother in law and I converted a 90s Trek Multitrack for his drop bar gravel bike. Used 41mm tires.


As for geometry, for at least a few years in the 90s, the Trek 520 touring frame had identical geometry to Trek 7XX Multitrack hybrids.
And my Univega didn't have an overly long top tube. Schwinn CrissCross and CrossCut hybrids don't have long top tubes either, at least not that I remember from refurbishing them.

Are we sure about this though?

What's a little overstatement between forumites?
