Let's try science: erm.. I don't have it written down anywhere (don't really want to know total cost!), but from memory:
Grips: superstar components
Brakes: Hope Tech M4 (bloody marvellous)
Bars: Syncros FR31 790mm
Stem: Syncros FR
Pedals: Superstar components Nanos
Wheels: Halo Freedom (gold hub is a Hope ProII to replace the sh1t halo one, only colour they had)
Shifters: X0 red
Rear mech: X0 red
Fork: 2010 Reba Team 120mm
cables& outers: Jagwire/BBB
Tires vary, I find MKs great in the slop, Ardents good for most of the year, and RRs best in summer.
Next upgrade: new wheels, still white of course, but a bit lighter and prob tubeless. Everyone needs 2 sets of wheels do they not?
