For years bike designers were working to make better full sus frames. Fantastically the non-bob shocks came along and....fixed/assisted the poorer designs.
But this meant that allot of big companies stopped working on designing better full sus bikes because they could rely on the shocks to fix the poor engineering.
The new Santa Cruz Lt that uses a revised Vpp rear sus design actually uses:
Fox Float R.
ie the rear sus design is so good it isnt using a pro-pedal/non-bob design shock.
Just think that in time a really great sus design could potentially have no shock at all.....(um just like they were trying to disign before).
Things are getting better and better
