Saddle to bar drop(6 posts)

I'm having trouble finding some info on this, so if someone could help me that would be great. How is saddle to bar drop measured? from the top of the seat to the top of the handle bars? or somewhere else (drops, hoods...)?

Also, once i figure out where to measure this, whats a good general distance to start with, for racing and training?

and lastly, before i do anything drastic (cutting the steerer down) is it ok to ride with 2" of spacers above the stem (thomson stem on an alloy steerer OCLV fork with a cane creek IS headset)?

Your measuring the drop correctly. The distance is the one your comfortable with and it depends upon many factors includung how flexable you are. According to the stem police 2" is too much. If that works for you, go for it. 2" is OK for an alloy steerer, If it were carbon it would be too much. If I were you, I wuld get several different size spacers and play with the height by adding them above and below the stem to make sure you find the spot is right for you. I would then ride the bike like that, for at least a week or two, before I cut anything. It's easy to take off, impossible to put back.

My two cents.

I thought he was asking about spacers ABOVE the stem. Why would it matter how much is above? I thought all that mattered was how far the stem was above the head tube (ie how many spacers are below the stem).

Did you ever notice the pros bikes in the spring, there is a big stack under the stem as they ride more miles the spacers start to come out from under the stem and go over the stem as they lower the position and become more flexible, this is the beauty of treadless and also the reason you may not want to cut that steer tube to short. Aside from looking a bit strange how many spacers you put over the stem should not matter.
"The beauty of threadless?" Quill stems do that all day long.Silverback

No biggie, but it's way easier to change the height of a quill stem than a threadless. Just loosen the bolt, push down or pull up and tighten the bolt. I can do it in 10 seconds.

True Temper the maker of the Alpha Q Sub 3 say 40MM max. on a all carbon tube. The very best thing to do is adjust your stack height go for a ride make a change ride again, remember what feels good in the driveway may not feel good 20 miles into your ride, take your time and do it right cause you only get one shot at cutting the steer tube.
