…did it on a Meta 5 with Pikes this year!!
Depends on what you what to achieve results wise really…
I've got an 09 and found it a little steep on the lower switchbacks and the rp23 was a little too inconsistent for my uber faffing set-up….super light build though so great to pedal!!
I'm doing it again next year but prob on a 6" with coils fr&Rr…..the Coils pikes up front are fine though…just run them with a 66 or 67 deg head angle…
If you're not too fussed about rear shock consistency then you'll be okay with the rp23 too…
BUT – if you've got a larger bike for the quali….then use it…oh, and don't forget to get a UCI license….you'll be provided with a better position on the quali grid!!
