I am looking to replace one threadless stem with another and I wonder if it is as easy as it looks. Do I stimply remove the top cap and two side bolts, take off the old stem and replace with a new stem? Do I have to do anything with the headset?
It is pretty easy to do. Make sure that when you swap the stems that you tighten the cap before you clamp down the new stem. Park Tool's webpage has a fairly good how-to section if you need directions.
1. Unless your stems have exactly the same clamp height you might have to add or delete a stack spacer. That's not a big deal.
2. When you install your new stem you will have to reset your headset bearing preload. That's not a big deal either as long as you do it in the right sequence. Check the Park Tool website if you're not sure.
