I know that. but your computer will have a stereo in (mic) and a stereo out (headphones). 3.5mm jack lead out of headphones and into mic, then hit play on logic and record on fm8. It's not rocket science.
I had the alienation knock-off hazard lites (same cross section etc) in 24" on my leeson. They were really stiff and strong. Chrome was cool for brakes too.
I did a very similar thing ages ago with a file, some standard magura clams and a 2-bolt RB booster. Didn't feel noticeably different at the lever, but it's a hel of a lot neater and also less force on the bolts/threads in the frame.
I broke my collar bone on a bmx. I was told to not to stuff for a few weeks (8-10 I think), but I was riding again after about 4 weeks and it's healed fine.
