    Stem length?

    Building a FG bike based around a Leader 72TS frame and S803 fork. It's a 61cm frame and I am going to run bullhorns. My current road bike is a 61cm Panasonic DX-3000 road bike from the mid 80s. This bike has a 90mm stem and drop bars, and I find if quite comfortable. I ride almost always on the top of the bars, on the brake hoods. Would a 90mm stem be a good place to start, or would I most likely want a longer or shorter stem?

    You usually use a shorter stem with bullhorns, but 90mm is pretty short to begin with, so try it out.

    The reach of the bullhorns is also a factor...some are longer than others.

    I run a 90mm with nitto rb-010aa (short reach) and it's good for me

    measure to total reach of your Panasonic and try to copy that onto the Leader. Headtube length is a factor but you might be able to compensate with headset spacers

    I had a similar question but going from drops to drops. Tell you what Scrod told me: try the 90mm and start from there.

    don't 'try' anything...do this. why guess when you know what works? measure the reach to your favorite hand position and duplicate (rear edge of saddle to hood points/bull horn ends are suggested references). ideally you match both vertical and horizontal, but just matching total is better than nothing.

    Stem angle?

    Getting a dimension stem for my new FG build. Frame/Fork is a Leader 722TS & S803. I will be running bullhorn bars. I need to decide whether to get the 83/97 stem or the 73/107. I honestly have no idea which would work best for me, or how to figure it out.

    Buy them both, send back/return/sell the one you don't like, only start one thread about the same topic at a time.

    Dude, why don't you put all of your questions, into 1 thread.

    Stem angle?

    I'm posting the questions as I think of them. While both of my recent ones involved a stem, they really were two different questions.

    Its pretty much common sense here man. Its a 7 degree stem, or a 17 degree stem. They can be flipped up or down. So do you want a little rise, a lot of rise, a little drop, or a lot of drop?

    Those stems are cheap enough to buy 5 and try a few to be honest. Then you can go ahead and grab a thomson when you know what you want.

    Please don't assume it's common sense just because you understand it. Most stems I've seen list angle has plus or minus a certain degree. I've never seen a stem listed this way.

    Merged.

    Smurray, you don't need a thread for each question.


    Dude, go to a shop and try before you buy. That's why bike shops exist. Take advantage of them. Their stems aren't that expensive. You may save $10 by buying online...IF you buy the right thing.

    The plus or minus degree is when it gets flipped. For example a 0 degree (also listed as a 90 degree) will be a straight stem. No matter which way you put it on, it will be the same. It will be a 90 degree angle from the steerer tube. Straight out.

    Now a stem listed as 83/97 is a 7 degree stem. Depending how you flip it, it will either rise 7 degrees, or drop 7 degrees. The angle it will make with the steerer tube is 83/97.

    Hope that helps.

    To follow on what diff explained - take the shown number of the stem and subtract from 90. The 90 is 90 degrees. So, a 83/97 degree stem minus 90 degrees will be +7 and -7 degrees depending on if you have it flipped up or flipped down. The same formula for the other sized stems.
