after riding the pulse thats fully ridged the cake mushy
Two different kinds of bikes that take a different riding style.
The Pulse will take finesse. It should be a strong climber, lightweight, and precise. Pick your lines wisely coming back down the mountain.
The Cake will require more saddle time and a smooth, steady pedal stroke on climbs. I don't think out of saddle mashing will get you much.
Coming back down, you will be faster than your Pulse.
I haven't found hardtails to be faster or slower than full suspension bikes.
Though I will say that the faster you go, the more valuable full suspension becomes.
If you go down hill at 3mph....doesn't matter what bike you're riding.
