I got an opportunity to test full suspension Ghost bike, model RT, from our local shop here in Croatia.
The bike is equipped with slx components, except wheels that have xt hubs, RS Reba 100mm, X-fusion 02RL rear shock.
-bike is very good on uphils, easy to climb.. on downhills very good control
-tires (rocket ron 2.25) superb
-slx brakes are great for xc rides, good power and modulation
-bike looks very great, I know that is subjective matter but..
-rear suspension doesn't work imho very well, I was driveing on 35% sag becouse on 25% the suspension was very rigid.. even on 35% in wasn't smooth.. I know it is race bike, but this bike is worth a lot of money and I think they missed the design of suspension..
I don't have a lot of experience with full susp bikes, I've tried specialized epic and my merida lrs (have exactly same shock on it) and both bikes have much better rear suspension
