I, like most cyclists I know, am very obsessive about bike fit and ergonomics, but especially so with my steering assembly.

This is what I'm running right now:

Felt F4 - 54cm
Bar: Deda Newton Deep Drop, 42cm
Stem: Ritchey WCS 110mm/-6 degrees
Headset: Cane Creek Integrated
Spacer Stack Height: 15mm
Bar Tape: Deda Elementi

Surly Cross Check - 52cm
Bar: 3T Ergosum Pro, 42cm
Stem: Thomson X4 110mm/+10 degrees
Headset: Cane Creek S-3
Spacer Stack Height: 35mm
Bar Tape: Deda Elementi

What is your current/preferred set-up?
