As I remember buying my threadless stem and bar combo a few years back, the question of angle came up and the LBS mentioned I could flip the stem and try the other angle if I did not like the first one. I was shopping at aebike for bars and stems and ran across a Dimension adjustable angle stem that is the correct length for me and diameter for a set of Nitto bars I am thinking about buying and on top of that, it's silver!! Anyone tried one of these? seems to have adjustability from 80* to 130*, adjustment is done through loosening an allen screw and the stem pivots nothing bulky about it at all. $25 or so. Did I mention it's silver?

I've seen these, but never used one. If you're not sure what size or angle you need, it might be a viable option.

I have a Ritchey adjustable stem. Works well. I would buy it. Especially in SILVER!

I have no idea what angle I like either or if it even matters. All of my quill stems appear to be the same angle (73* I think)and my threadless is a 80* and if I flip it, it gets taller, I don't need taller. This opens a whole can of schnot I would rather not deal with and the reason I really don't like threadless. Honestly my current setup looks cobbled together. I intentionally left the steer tube a little longer and put 1 spacer under the cap on top just in case I did not like my position(have 2 spacers on the bottom) and then their is the stupid frankenbolts of the stem to bolt into position on the tube. Nothing elegant or simple about the whole setup. I also ran into a few compatability and price issues with the bars I'm considering. Was looking at the 45cm 177 noodles, $52 and the more narrow version is $20 cheaper,WTF? And some of the stems were 26.0 and others were 25.4 but not available in silver or my length but I looked around further and I just need to be selective with getting the right length/diameter/width/style/mfger when picking the combo out. Can't believe this, 3 years now on this bike and still don't have the fit dialed in yet. Final touches might be a white San Marco and white bar tape.

:lol: LMAO! I feel your pain. Ain't new technology great? Truth be told - I'm anything but anti-technology and new ideas. I just prefer things that make sense. The quill stem was an elegant and simple design. Then someone with way too much time on their hands decided to redesign it. And to what end? Has anything, (besides the seller's pockets), noticably improved? Don't even get me started on oversized bars, embroidered saddles, and carbon fiber bar ends. Pretty soon now, someone is going to start selling CF toothpicks, or maybe rollers with CF rails. Yeah! That'd make a lot of sense.

I've been racing & riding since the '50s The truly helpful, beneficial, techno changes I've seen since then are few. Index shifting, brifters, clipless pedals, and the use of new materials, (in SOME applications) are some that come to mind. Tires have come a long way, as have rim materials & designs. Aside from that, IMO, everything else is just hype, gingerbread or outright bull$hit.

I could do the Dimension adjustable stem in SILVER ($25) the Nitto Classics ($25) and shims @ $9 to make the whole thing work. But then I'd have to go buy silver spacers or strip the black off the existing spacers. It never ends, as bad as remodeling a house.

If you've been riding for years, surely you know what bar height you prefer, measured from the floor to the top of the bars. It's not hard at all to convert any bar height into a combination of steering tube length, spacers and stem angle to produce that height.

Stay away from adjustable stems. They always detract 30 "coolness points" from your bike. Make your measurements, and buy the correct stem.

Use this chart to figure out what size stem to buy. Use your best-fitting stem as a guide.

this assumes the same BB height.... works when dialing in fit of a given frame, but if fitting a new frame it might not be correct.

as a temporary fitting tool they are ok... 'cept those adjustable angle ones have limited range, better to go with (borrow!) an (almost) infinitely adjustable look ergostem type... esp if the OP "don't need taller"... if height ain't the issue, I don't think the adjustable angle stem is the answer... if lower is desired then just move the spacers. Frankly I cannot tell what OP is trying to achieve. "3 years now on this bike and still don't have the fit dialed in yet"... wow.

About 99% of modern road frames have a BB drop that's within a few millimeters of 7cm. Most that deviate tend to have a little less drop, except for Serotta, where 8cm is more common.

true again... but if somebody not as smart as us is going from road to cx or doesn't use the exact same tires there could be a small difference

give me 3 of 'em an a couple pair of those black knee high tube socks.

All are set up fairly close and I want the Ti to fit closer to what the other bikes fit. Sort of feel like I'm sitting too high and stretched out further than the rest of the fleet. Overall, feel sort of "inefficient" position wise. I moved a second 1cm spacer above the stem and will try that out as I took some measurements and confirmed that the bars are higher than the rest of the fleet, along with the new 36t ring I put on. Hopefully fit wise and drive train wise I might find my groove with the bike yet.

No,no,no,no! Good God man, don't you know ANYTHING? :mad2:

You have to get the white ones with the 2 red stripes around the top.

If you're trying to match fit to another bike it should be easy, assuming same crank lengths and similar saddles..... fit saddle and bars in relation to BB center independently, i.e., don't fit bars in relation to saddle. Saddle height and setback should be easy to match... for bars on vertical axis, measure bar height from ground and subtract BB height to give bars to BB- match this measurement on both bikes (make sure bike is level). for bars on horizontal, drop a plumb line from the bars and measure to BB (you can also drop a plumb from the BB, but it's easier to just go from BB center to plumb taking the shortest measurement, again make sure bike is level). If you change crank length then you might need to adjust saddle height (lower for longer, fit for 6 o'clock) and then adjust bars accordingly. easy

And trying to put my finger on just what I don't like and how am i going to fix it. First off the frame is not too large. I just don't feel balanced, as if my arse is not under me, too far back to use the glutes for power and the reason it feels like that is i feel like I have to reach too far out to grab the hoods. All of my bikes (except the ti) have a measurement that i call cockpit (front tip of the saddle to the front of the handlebars for me 22" is good) and a second followup measurement I call sleeve (center of the saddle where the post would be if it came through the saddle to the front of the hood with the front wheel centered, for me 34" is good) I don't have either of those with this bike, I got 23" and 35". Now something else I take into consideration is saddle length; all of my other saddles are 270mm except the one on the ti, 260mm San Marco Concor. I gained 1 cm there with cockpit measurement and is corrected for in measurement when I do sleeve/reach measurement. I may have gained more room when i swapped out the creaking seatpost for a new one possibly more setback than previous. I just slide the seat forward some to compensate. And with the bike in the trainer and I sit down if I grab the bars about where the hood rubber starts about 1/2" is under the thumb webbing is comfortable. It is when i have to reach and grab the hoods(my 90% riding postion) then i feel the reach, like I can just get my fingertips on something I am reaching for on a shelf yet i can't fully grab it.

My thoughts are that I am going to swap out my 110 stem for a 90 and get some different bars as i do't like the ones i currently have. I know I'm close on fit on this one and I'm fairly sure the stem angle of 80 works for me, i just need to pull the bars back to me about 1" and all should be right in my ti world.

I ordered a 90mm stem and a pair of Nitto Classic bend bars, hopefully this will get the bars to where I want them and my hands will also feel happy also.
