geoinmillbrook said:1.)From crappy old Araya touring wheels to Mavic Cosmos with 130psi Contis.. rolls much nicer, climbs a little better, even with my 200lb load.
2.) Wider handlebars - opens up chest for better breathing
3.) Went to Ultegra derailleurs - they seem to index more accurately and more positively, I used to have to play with the 105 front triple more.
4.) From crappy Bike Nashbar to SRAM force chain. Huge difference in shifting smoothness and rust resistance.
5.) Seat ! From hard as a rock C'dale stocker to something more anatomically designed and comfortable (WTB Race or something)
That's it.

interesting one with the handlebars - when i bought mine, i swapped in a slightly narrower set of bars, cos im used to them a bit narrow... lose some torque in sprints, but the breathing seems to be fine? and the aero is worth it, i think?
