I'm looking to buy a Jett 155 or Ruby 155. I really don't care on the color. I'm just wanting to try one out before I spring for a Brooks. I think one of these will work for me. I'm 5'7, 180lbs, a sit bone measurement of 140mm. I'm fairly new to riding, so I might sit heavy in the saddle. Any other suggestion are welcome, but so far this is what I'm thinking of trying. Please don't laugh, but I'm trying to not spend a crap-ton of money!!
