seat angle

speedy fro

I was wondering what effect seat angles have on freeride bikes. I was thinking of buying a Kona Coiler, and it has a 72 degree seat angle. If i put the seat up to cross county height, would i be to stretched out or too far over the back? why do freeride bikes have slack seat angles? all help very appreciated

Freeride and downhill bikes tend to have slacker angles in order to keep the riders weight further back on the rear wheel as well as positioning the rider further back so when you get of the saddle to go down or drop your weight is as far back as possible. Usually this is combined with a very short stem so you can drop your weight to the rear easily. XC bikes have steeper angles to position the rider closer to the middle and weight down the front wheel during climbs to keep it from lifting up. This of course makes the bikes more susceptible to endo when pointing down.
On most freeride bikes you are still able to set the saddle in a XC style position by using a seatpost with little or no setback just as you can move it further back on a XC bike with a seatpost with more setback. Unless the seat angle is extremely slack you can easily set it at XC positioning with the right post.
72 degree's however is actually a fairly steep angle and is pretty average for many XC and trail type bikes.
