I hope y'all don't mind me joining in. Just finished building (at least to the point of being rideable) this mountain bike this morning, have not had an off-road bicycle since 1997.
It is a 1996 Caloi Elite frame with a modified Quadra 21R fork, and mostly used parts from ebay. Much to my surprise, it came out at 27.4 pounds, I was expecting it to be over 30 with that fork. I spent some time today between road rides doing laps around the yard adjusting things. It feels like it fits me, but it has been so long since I have ridden offroad I may be mistaken. If nothing else, it was fun to put together.
