umm it comes in at 16kg's..... no it's not the lightest bike, but it is super stiff....... Yes it's justa swinger 4 way.... i wouldent recomend them for this type of riding, unless you have someone to give you new ones or fix them, since i have had the bike, the shock has spent more time out of the bike getting fixed than on it. I'm going to get a coil swinger when they make them with that eye to eye and stroke length..... you cant have a Yeti any other colour in my opinion. As for price i got it complete second hand for $3500 which is a hell of alot cheaper than a new frame would cost alone. I have changed a few bit's and spent some money on it. Put the mini's on instead of hayes, upgraded to 04 shermans, put on the MRP instead of a tru-vative, and a different wheelset.
