Did a bit of work on it over the weekend:
Managed to get the RP23 rear shock fitted instead of the 5th Element after receiving the fitting kit and new bushes for the front mount.
Swapped the SIDs for my Rebas World Cups.
Swapped the Ritchey WCS Stem for a Syntace one and the Monkeylite bars for RaceFace carbon ones; they're a bit wider and slightly less back sweep.
Swapped the USE Alien 'post for a Syncros Ti one as it's in-line rather than lay-back

The RaceFace chainset was swapped for a Middleburn RS8 Duo which the Yeti will share with my King Kahuna
The Dura-Ace mech was swapped for an M952. Oh, and fitted a Sram 9spd 'attack' gripshift as the right hand shifter instead of the x-ray 8spd. Oh yeah, also M953 9spd cassette
Took it out for a little 'pootle' today and seems to be working quite nicely. Rear shock will probably need a service though :roll:
Cleaned, post-ride....
I do wish (some) dog owners would be more responsible with their mutts produce :roll: :evil:
