Mary McConneloug has raced Seven mountain bikes to four national titles and in two Olympic Games. The Sola IMX SL uses carbon fiber top and seat tubes and double-butted titanium elsewhere to create a top-of-the-line mountain bike frame. Seven also offers full titanium and steel frames. After a lengthy discussion with each customer, Seven helps decide on full custom geometry, ride quality particulars, frame add-ons and finishes. You are guaranteed to get exactly the mountain bike you�ve always wanted from the folks in Watertown, Massachusetts.
