finally got the slick e13 direct mount stem for boxxers, and installed it over the weekend. took advantage to trim the steerer tube a bit too. i now see why they don't recommend running 25.4 carbon bars w/ this stem, as you really need to work to get the shims in over the curved part of the bar. of course, this means i can now use the thomson stem on my bike a bit of advice; if you are cutting steerer tubes, make sure the star nut is not in the path of the cut. i thought my hacksaw blade was really worn out.
