Cannondale M800 Stem
Looks like Nitto makes an adapter to adapt to a threadless stem (second one down): https://www.universalcycles.com/shop...s.php?id=23896

I think that Nitto adapter looks like your best bet and it actually looks pretty clean - plus it then gives you infinite options with 1-1/8" threadless stems to dial in the fit. That Soma stem might work, but it also lacks a removable faceplate - which may or may not make bar changes a pain?
Good luck!
Good luck!

Here's my dirt dropped Slingshot
Due to it being a singlespeed I can swap over to a flat bar setup in about 5-10 minutes

Lovely jobs on both of them, thankfully the Cannondale is quite a tall frame so I don't need to gain as much height as you did on the Slingshot. When I was buying the Cannondale on holidays in Florida, I think the other one I was considering was a Stumpjumper, which might have made life a bit easier.

Cannondale M800
Hi Korina, That's a very similar bike to my M800, it's even the same colour ! I'm not sure what you're asking though ? Do you mean would the bike be suitable for a drop bar conversion ? If so, then you would have the same problem I have, as it looks like it has the same 1 1/4" Pepperoni Forks. The best option seems to be a Nitto MTC-023 Quill to Threadless Adapter, and then some sort of suitable riser stem on top of that.

ETA: Oh wait, you were looking for a stem. This one looks alarmingly rusted, so never mind.

Cannondale M800 Stem
Ah, right, I see. Thanks for the thought. It's probably not worth $300, but it's quite a nice bike, would be easily tidied up. The frame and fork look sound, and are aluminium so wouldn't be rusty, the stem etc would be easily replaced with similar ones. Problem arises when you want to convert to drops. The Nitto Adapters I mentioned are hard to find, they may not be making them any longer, or maybe it's just Covid supply-chain issues. I think I have one on the way from Tokyo, hopefully it will get here, and I sourced an adjustable stem that should give some extra height. Loads of bits ordered now, waiting for various packages to arrive, Tyres, Mudguards, Shifters, Brake Levers, Bars, Stem and Nitto Adapter from various sources. Lots of postman visits coming up.

'94 Rockhopper rebirth
I had this bike since new. It was neglected in the garage occasionally used by my dad. I decided to give it a second lease on life by converting it to drop bars.
So far it rides well. I'm thinking of upgrading the wheels. I see some Rhyno Lites on eBay for $200. Worth it? Any other recs?

Is it weird that I like quill stems? Super easy to adjust, and they just look pretty. FYI, Factory Five makes a 1" quill stem that takes 31.8mm handlebars. A bit spendy, but very cool.

Nice bike, though I might be biased. If you're looking to sell it, no, new wheels aren't worth it. If you're looking to ride it, then hells yeah! I'd say get the wheels, ride it, see if you want to change anything, ride it some more to be sure, change what you want, and ride it.

I should have mentioned my current rims' brake surfaces are scored to the point where braking power has been reduced. I'm looking for quality replacement wheels for myself. I will never recoup the money I've put into reviving it so far. That's not the issue. Also thinking of converting to Linear Pull brakes, like Paul Motolites

Great build on the Stumpy there! Any updates on it? Ride reports with the gearing etc? Any more pictures?
I have an '84 as well and I'm trying to figure out what to do with it. I originally built it up as a drop bar tourer, but my weight and load caused that bike to climb like spaghetti noodles. My paint is oxidized, but was hesitant to paint over original. I think yours pushed me to do it.

At this exact moment, it's basically a 48-24 double. Upon my most recent chain replacement - earlier this week - the middle ring apparently no longer meshes with new chains. Not a surprise, looking at it:
So I'll need to fix that.

I didn't actually paint mine; the powder coat was done by the previous owner. Which is actually a bit unfortunate because, although the color works nicely, it wasn't done entirely well. The underlying steel is poking through in places like lug edges.
Any more pictures?

[QUOTE=KlunkerBiker;21500584]So, here are some pics of my 83 Stumpy. The only one I have of it finished is the second to last one unfortunately. The last picture is of it's current state. I think I will build it as a flat bar city style bike next.

Hey it's been awhile but with COVID-19 I have more time to jump onto bike forums for ****s and giggles.
I'm liking a lot of these older MTB with drop bars. I just purchased an older MTB off Craigslist that I was planning on turning into a crusty, nondescript (read 'not worth stealing') town bike. The seller didn't have much info on the bike; its been painted over at least once and doesn't have many original parts left.
I've started stripping it down as I intend on replacing the basics (cables, housing, brake pads, etc.) and clean it up a bit before I start riding it. Maybe I'll throw some drop bars on it.

Will do!
I've managed to get most of the components off. A friend/coworker of mine who has way more tools and experience wrenching bikes helped by removing the headset and bottom bracket.
The frame is starting to reveal itself (and perhaps it's next iteration) now that it's naked. I'll be stripping paint next.
Oh yeah it also appears to be an early 90's Mongoose MTB but I have no idea what model. Any guesses?
What is this frame?

Mongoose IBOC, don't know the years super well. Mine has the loop tail stays like that, but no cutouts, and no stamping.
Edit again: Though early '90's, could actually be pretty late.
