I have a 2009 Heckler I have been riding for a few months now (large, fox rp23, fox float 32 140mm). I have experimented with suspension setup and tire pressure. I ride trails that are mainly xc/trail type. I'm not doing drops or jumps just hitting lots of singletrack with a mix of climbing and going down and lots of roots, logs etc. The bike rails turns and handles great. The problem is no matter how I set the bike up it seems I am fighting to pedal and keep momentum especially when the trail gets choppy. Unless I am going down or straight and smooth it feels as if I am towing a cinder block. I took my other bike (Giant Trance X1 maestro, 5" front and back) out and rode the same trials a few weeks ago and the bike felt like a rocketship. Climbed better, rolled and kept momentum better and it only weighs about a pound lighter. So, I guess my question is this a matter of a difference in suspension design? Single pivot vs multi link? or is there something else I should try setup wise? My riding partner took my Heckler for a spin today and made the same analysis so I know I'm not imagining this.
