It's not a MTB but it's a vintage drop bar conversion...

I agree this is probably not how that type of bar was "intended" to be set up. But I don't think it really matters - I think as long as people are happy, comfortable, and out riding that's the main thing!

Since I ride mostly on road, I have a Nitto Randonneur bar. I like the flat ramps for most riding, but also the shallow flared drops work ok offroad and for headwinds.

In my experience, the stem has to be short to get the reach right so the primary riding position is in the drops, which can allow for a shorter stem height. I found that rotating the bars so the drops are at an angle allowed for an aggressive and stable stance. I found that the flats on the Portola weren't really good for technical riding, just a change of position. It looks like abshipp preferred to set up the bars so that the hoods would be the preferred position?

Here's how I liked my Portolas, not a lot of room on the hoods:


I don't have good profile pic, but I set up some Origin 8 drops the same way:

I agree with @yangmusa. Set your bars up however you want. Nearly all the bikes I see are set up differently than how my bikes are set up. There's no "right" way to do it.

Bars are like saddles, everyone is comfortable in a different position. By using the bars from and old Nishiki International on my '87 Renegade (Raleigh Canada) I got to set everything up fairly level. I don't use the bike for extended high speed single track so these work great. I have Salsa Cowbells on my Vaya and would not want more flare than that.

This exact thing worked for me, too.

How do you like the Panaracer Comets? I'm looking at those for an upcoming drop-bar build and am wondering about their ride quality vs. rolling resistance on pavement vs. gravel. Their price is certainly the reason I'm looking at them in the first place, just hoping they might be decent for mixed conditions. Any comments?
Thank you! I love the all-Nitto cockpit. I only have maybe 25 miles on the Comets so far, with 20 on pavement and 5 in really wet fine gravel. Running about 40 PSI, they seem to roll quite well, are pretty quiet, and my brief foray into some loose stuff didn't bring out anything alarming. I was quite surprised that I never broke the rear end loose, but that may be more to do with, as Squeeze so eloquently put it below:

Thanks! Its funny to switch between a road bike and this thing. Stability over agility is the name of the game with the Mirada.

I have a question for all the drop bar MTB people. I often see people put those dirt drop bars on bikes like this with the bars angled upwards, so that the ramps are flat and the drops have a somewhat extreme angle, as abshipp's bike above.
I tried that setup once with a pair of Soma Portola dirt drop bars. My experience was that with the bars angled up like that the reach of the bars was pretty long. And being in the drops was somewhat impractical, because with that upward angle they were farther away, which meant I'd have to lean forward quite a bit and get low to be in the drops. Ultimately they were pretty uncomfortable in any position because both the hoods and the drops were quite far away with the bars angled up.

My takeaway from this experience was that these types of bars were designed to be angled so that the drops are parallel to the ground, or almost parallel, and the drops (behind the brake levers) would be the primary riding position. This makes the reach reasonable, and coupled with a very tall stem, allows you to have a wider hand position for off-road handling, and more leverage on the brake levers. If you look at the original WTB and Nitto dirt drops, that's how these were always set up.

So I'm confused why people angle them upwards, taking away all their advantages so they could ride on the hoods like a normal drop bar. If one wanted a position like this, I feel like a drop bar with a short reach and very shallow drops would make more sense (for example, the Soma Condor, or Salsa Cowbell, etc) for this riding position. With the dirt drops angled up like that, they just seem like a drop bar with a long reach and far-away drops, the opposite of what someone would want for offroad!

Anybody share this opinion or is my analysis idiosyncratic?
I have to admit that the particular angle that this picture was taken is a bit misleading. The ramps are not flat, but angled quite far down. The drops are maybe 20 degrees away from parallel with the ground. You can ride on the ramps with some interesting wrist contortions, but the two main positions are really just the tops and the drops.

Took a minute, but I finally set up my 1991 Raleigh Technium Chill with Origin8 Gary-2 bar. Wheelset bought locally, mavic 117 S.U.P laced to some old school zip speed weaponry hubs and cook bros skewers. Threw on a NOS ideale TB90 saddle which I was super stoked to buy locally after I saw it posted on eBay. Recently added a simple rack with a Walmart-sourced dish rack to keep things funky.

Whoa, cool. What's the rack underneath the dish rack?

Ross Mt. St. Helens update

I posted this awhile back, but finally got around to finishing up this '84 Ross Mt St. Helens. It's been a great winter / gravel / dirt / whatever ride so far.

Hot dang that thing is a beast! And another build with Panaracer Comets... how do you like them?
I feel like I saw one of these with that same crankset on the Tallahassee Craigslist a while back but never could make the drive to check it out. Now I'm wishing I tried harder!

Last year I bought a lightly used, inexpensive Schwinn Frontier from craigslist to keep in my office in the city for lunchtime rides to the library, taco stands, errands, etc. I am finally getting around to replacing the narrow flat bars and twist-grip shifters with something else.





Those drop bars aren't right for me with that stem on that frame but it was a fun exercise and an excuse to post not one but TWO drop-bar MTBs here.

I repainted the bike. It doesn't show in the pics but it has a blue pearl clear coat. I ride the snot out of it.
