Agreed, plus I already bought the damn thing. A couple more failed attempts this weekend.

That looks terrific. Very nice job.
From my perspective you just cannot go into a bike shop and come away with a bike as cool as that for the amount invested.
These vintage mtb's are so versatile with what can be done with them,
like a blank artist palette waiting for the artist to customize them to their preferences.
Way to go 'artist' frantik.
Safe pedaling.

Great, love the gumwalls and Biopace that bar tape does more than just match the paint accents it makes a statement.

All these conversions look so sweet! Wish I hadn't looked at this forum......My city bike is a Raleigh Mountain Tour (Deore/Biopace/triple butted/bull horned fast menace! I use 1.5" Conti City Contacts. Nice light comfortable bike. BUT, it's itching me to see it dressed out in drops! Kinda like the day before the
honeymoon....Ha!

This is really a mechanics question, but I figured there's more collective knowledge about this on this thread than anywhere else on the forum, AND IT'S ALL YOUR (collective) FAULT THAT I'M IN THIS PREDICAMENT…
Has anyone successfully negotiated an On-One Midge Bar through a 25.4mm dia. Nitto Dirt Drop stem? If so, please share some pointers with me. I tried using a screwdriver as a lever/wedge, but was only willing to open up the stem so far, and I'm getting jammed up. Please help. I want to show some WIP pics, but it helps to get the drops on the drop bar conversion before showing pics. It's going to be a brutishly beautiful Kuwahara doomsday tourer.

I used this method to get my Midge bars through a Kalloy dirt drop. Almost put a hole in the dime, but it worked.

1998 Gary Fisher Wahoo
1998 Gary Fisher Wahoo (cromo, plain gauge)
Tiagra/105/LX/XTR mix
30.5lbs as pictured
Things I'm still working on:
1) Bars are 40cm, which is a bit narrower than I'd like.
2) Few options for 25.4mm drop bars, and few options for 26.0mm 1 1/8 quill stems.
3) Frame isn't worth a new threadless fork, headset, and stem
4) Frame is way heavy, and I'd like a steeper headtube angle and lower bb
5) Replacing tires (640g each), pedals, wheels, and saddle can save me several easy pounds
Considering a lighter (alu?) frame with an undersized fork to steepen the headtube and lower the bb

I'm not usually a fan of Fishers except for the original ones but your Wahoo looks great! Can I ask what stem you are running? I've been searching for a quill stem with a detachable face plate, that said I don't care for the one Niagra sells with the bolts on top as it blows the beauty of a traditional quill stem. Your stem still has the classic look but with the bolts on the bottom really lends itself to being a versatile stem with a traditional feel.
Really nice build, thanks for sharing!

pssst... frantik,
Did I ever ask you for formal permission to join the Chainstay Brake Mafia?
If not, here is my whip for consideration... a 1987 Panasonic Mountain Cub 7500. I fully redid the 1987 MC7500 from green and yellow "7Up" colors to the gloss black of the 1988 model. Almost all the Shimano XT is period correct aside from some newer 7 speed XT shifter pods mounted on DKG Shift-Ease mounts with a 7 speed XT rear cassette and derailleur. The front brake caliper is a XT "Deerhead" so I could run a Rick Hunter NUG for some micro-adjustment in the caliper (the PAUL CX Race Team runs them, certainly good enough for my slow "Clydesdale" racing). I had the decals made by DYI Decals online, they had the exact catalog font with a 3 color vinyl decal. As always, I'm running my favorite drop bar, the One One Midge with NOS Modolo Race levers with some Torelli bar tape.
I hope the build is up to snuff a this is my first u-brake dirt drop build...

The stem is from a Trek Allant. No idea if it's possible to buy one separately, but it was a great find. If I go the threadless route, I'll post it here first.
It looks a bit like a whale. Might add some googly eyes.

I just put drops on my '88 Schwinn KOM-10. It was a good old bike before, now it's an excellent and fast gravel crusher. I can get low on the bike and get my weight in synergy with the bike's. I rode 50 miles on it yesterday, on about 60% gravel and B roads, in about 4.5 hours! I'm definitely falling in love with this setup; the bike was under-served as an upright town bike.





The bike is very original, with a lugged Prestige frame, and a full Deore XT-M730 group (including chainstay U-brake). The brakes work great with new cables and Kool-stop pads.
I put on Nitto B135 Randonneur bars, Suntour bar-cons, cheapo brake levers and Kalloy stem. (I kept the original take-offs, even the tires). The tires are ITS DJ Mk2, excellent 26 x 2.1 road/gravel tires for $18.

Love what you did with that Schwinn. That's a perfect middle-America 4th of July bike.
[edit] btw where did you find the tires? They look great but a quick search produced a lot of "out of stock" and bmx size; nothing in 26.

Your KOM really turned out nicely... definitely an overkill Townie!

Since it has a loud AMERICA!!! paint job, I call my bike "The King of 'Merica" or "The King" for short.
I originally wanted to try Nitto RM-14 Dirt Drop bars, but they're not in production and hard to find. (Well, they do currently make a Dirt Drop with a 31.8 clamp. I figured that out when I brought home my bike swap finds a couple weeks ago; I got that bar and the SQR bag shown. 1" threaded and 31.8 clamp are pretty much mutually exclusive, barring frankenstein solutions. Anyone want to buy a new 31.8 Dirt Drop bar?)
I had picked up the Nitto B135 bars in a parts lot earlier this year, so I gave them a try before buying a Midge. I can't compare the B135 to similar bars; my other bikes have: Nitto Moustache, Nitto B105 classic, and a flat bar on my MTB.
The B135 bars are the widest of Nitto's Randonneur bars, but they still feel a bit narrow at the top. Not too bad, though. I was able to get comfortable and you can tell by the 22" x 24" frame size that I'm not a small dude (6'1" 220#). I felt maybe a 1/4" or so of flex when I'm descending while on the bar ends. Not bad at all.
This thread gets into the differences between the B132 and B135 models. In short, the B135 has shorter ramps and longer drop ends.
I've found 5 usable hand positions on these bars: horizontal tops, top curve, ramps/hoods, hooks, and drop ends. The drop ends come back quite a bit more than most drop bars, and I've found that to be my favorite position. The ramp/hood position isn't as comfy as on my other bikes with more traditional drop bars, but then the el cheapo brake levers may not have very good hood shapes. These bars fit me well at this height, where the top is level with my seat but the drops are lower, for a more aggressive position.
Yeah, the KOM doesn't have anything that really differentiates itself from other top-end rigid MTBs from the era, just some small details. It's just a well-built, well-equipped bike. Mine was in very good original shape, with every original component but the seat. However, the frame has a ton of scratches (some nasty) from some metal storage hooks while it languished in the PO's garage. I'm gonna look for some touch-up paint (probably Testors) to cover them up.
My KOM was sold from Baraboo (WI) Schwinn, which apparently closed its doors at the end of the '88 season. I wonder if this bike was sold prior to closing or as part of a liquidation sale? The PO remembers riding the bike in high school in the 90s (purple registration sticker on the L seat stay) but doesn't know where it came from before that. The tread on the original Project KOM tires is at about 90%, but the sidewalls are all dried out.

Those tires were all over the web last fall, I found them at JensonUSA for $18 apiece. It seems like they ran out of that production run. Hopefully there will be a DJ Mk3 soon. They're made for 26" BMX dirt jumpers. They have NO puncture protection; you can see the reverse of the tread molding on the inside of the tire. But I've had no punctures yet and I've gone over some nasty rough gravel (almost 3" rocks in a couple sections) and nasty city streets.

Thanks for the complements. I knew the KOM was a good bike when I got it (for only $70 on craigslist!), but it took the drop bars for me to really feel great on it. Since it's a tall bike with a high BB, the upright riding position felt like I was perched on top of the bike, not part of it.
