So now I love really nice tools, and MC turned me onto Efficient Velo Tools, which is like a Toys'R'Us for geek bike mechanics like myself. I ordered the Smoothie Headset Press because it is the only one I've found that can press the sometimes long head tubes I build in the custom market.
The tool works like a dream, thanks in part to being able to get leverage at the bottom and top of the press (see the vise grip clamp at the bottom in the pics below), and a nice bearing underneath the "wingnut", which keeps the pressing action extra smooth.
The headset is my old standard -- a Chris King one and an eigth, in red with the stealthy Sotto Voce decals.
The bike is a Seven Sola S (full Ti)single speed 29er with slider dropouts (i'll post more on this bike when it's done).
