Hello Lightning 123, glad you are enjoying your Rockstar, still waiting for mine. I wonder if you could share a stat with me. I would like to know the size of the rear shock. I already ordered a front fork and would like to get a shock in before the bike arrives. some stuff will have to wait till I can take measurements but I pulled upgraded parts from my Stumpjumper before I sold it and I plan to make this new bike what I want before the first ride. I am taking the weight of the bike into consideration as well as my riding style. Looks like it isn't arriving till July ???. original delivery estimate was February. These bike were priced well so we have the option to improve the platform and ditch the cheap stuff. I hope you keep updating and I will share when mine comes together. ; )
