i find my Fritzz goes through the travel way to fast on the first stroke. iv had the shox serviced and tinkered with the air pressure,i do really enjoy how it descends BUT it climbs very slugish. another reason is that have snapped the rear chainstay once and dont have much faith in it along with snapping bolts twice on the drive side.
i ride in south wales by the way mainly do natural trail but might do cwmcarn as its on my doorstep
