I bought some new spacers to go with a new stem for my Kilo. The bike originally came with 50mm worth of spacers. I wanted less and with me being a noob only bought 40mm worth of new spacers without even considering the fact that the steerer tube would then be sticking up past the stem.

Is my only option if I want a shorter stack to get the tube cut? Is this a relatively quick and easy thing for a bike shop to do?
