    Stem position question

    I just adjusted my stem up one notch by moving one of the spacers above the stem on my Specialized Allez. The tube of the fork where the stem attaches ends about 1.5 cm before the top of the stem. Im wondering if this is safe. any help is appreciated.

    I wouldn't do it. Get a stem with more rise.

    I'm thinking that you mean the steerer tube stops short of "flush" with the stem so that there is a 1.5 cm gap from the stem top surface and steerer's top surface. Is this correct? My initial response was to just cut the excess off the steerer until I thought about what you were saying...

    If so, I don't think I do it. You'd would either have to put the stem back in the position where it was (I'm guessing it's too low to be comfortable to you), or purchase a stem with a narrower clamping surface. Hope this helps.

    Fifteen millimeters is a lot. If it was my bike, I'd start to worry at anything over 5mm. Some carbon steerer forks even specify placing a 5mm spacer above the stem so that the stem clamp can get a better grip on the steerer. If you feel like you need a higher handlebar position, I'd go for a stem that has a little more rise.

    No. That distance should be about 3 mm, just enough to allow the cap to apply some pressure to the top of the stem for adjustment before tightening the stem bolts to clamp everthing in place. At 1.5 cm you have effectively only one clamp bolt holding the stem in place. Take out spacers below the stem to get it down. If you need the bar higher flip the stem over so that it angles up.
    If it ain't broke, mess with it anyway!
