Bicycle Mechanics - spacers above stem/cutting steerer?
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
I very rarely ever see road bikes with spacers above the stem. With an alloy steerer you can cut the steerer once you are certain you want the stem lower. With a carbon steerer I understand that you should not cut the steerer. Do my observation and my understanding mean that riders cut their alloy steerers and do not lower their stems with carbon steerers?

Who says you can't/shouldn't cut a carbon steerer?

You can certainly cut a carbon steerer. You just have to be a little careful when doing it. I would recommend getting your LBS to do it for you (delicate things sometimes, carbon components).
my local bike shop cut both of my csrbon steerers with no problem, a winwood on my trek2000 and an alpha Q on my older Lemond :beer:
whoops, csrbon = carbon, darn illiterate fingers

You rarely see this, because it is usually only done temporarily, while dialing in your fit, often with a new bike, or an old bike with a new fork.
Let's say you want to test a lower riding position without making any permanent cuts. You pull the stem, remove a spacer or two, replace the stem, and then place the spacers that you just removed on top of the stem. You ride the bike awhile and realize you're too low. Reverse the process and add a spacer back below the stem and try that position for awhile.
When you're sure that the position is right, then you cut the steerer. This method simply allows you to test different positions without making permanent changes/cuts. Doesn't matter what the steerer is made of.
Just a quickie here. I would leave extra steerer to be able to move my bars up when I wanted to mount aero bars for time trialing or doing a flat ride where I wanted the extra option of an aero bar postition. Otherwise my bars were pretty comfortable in a lower position. I suppose I could flip the stem too or swap it out for a + stem but, this seemed to hit the perfect spot for what I was looking for. I always hated the finality of cutting the steerer. Maybe it's committment issues!
