I have a Soltera 7 with almost 4k on it. I have tried various bars to allow me to sit up a bit more and take the stress off my shoulders and neck. Finally!! A friend, who bought the Pace 4 on my wife's and my recommendation, asked me to try it. I was instantly in love with the swept back bars. I was so glad these were made available . They fit perfect, the only exception was the selection/on-off controll had to be repositioned, the wire was too short, no biggie. The other cables and wires routed perfectly. I can't tell you how much more comfortable my bike is. Btw, I'm in my 70's and comfort matters. I can now ride full range and feel ready to ride again the next day...really pleased with this purchase.
