My Ibis Mojo HD.
Have been riding this for a bit more than a year and slowly upgrading parts.
This is how it was set up when I bought it.
Brief specs.
Pike 160mm 27.5
Monarch+ debonair 8.5 x 2.5
Reverb
X0 trail brakes
XX1 crank
X0 derailleur
Kore bar/stem/grips
Currently running 26er haven wheels in 160mm rear travel mode, but I have a set of LB 30mm rims on DT240s in 27.5 which I have used in the past with a fox rp23 7.875x2.0 (140mm travel) and a Cane Creek DB air 7.875x2.25 (150mm travel).
Pretty happy with the current set up but it would be nice to run the 27.5 wheels with this much travel, they are a much nicer wheel and the havens break a spoke every second ride.
Haven't really got any more upgrades in mind except maybe some better 26 inch wheels. Maybe light bike 35mm or similar
All in all this is an awesome bike and gets ridden everywhere from xc-ish stuff to enduro races and some dh style shuttles. Only thing i would change would be longer reach. Maybe i need the new HD3!!
