JCL: You use the Thule 450 Crossroad square bars, correct? I am thinking that this is one of the best options for me. And then use the echelon tray for mounting the bike to the roof rack. Are you using the 58 inch bar? I am wondering if the 50 inch will work or if it is just to short. The 58 is what thule recommends. Took a nice 35 mile ride on the R3sl this morning. The new freehub is installed and I think the previous one was never right. The bike rolls much smoother and faster. I have heard that sometimes the freehubs come to tight from the shimano factory because they are machine tightened. Its gonna be time for new brake pads soon. I am going to replace with Swissstop Flash Pro Brake Pads GHP II,
