Walnutz is right, I think they might have added the Dia Compe part because I or someone else gave them cr@p about it. Did some digging around and found that the Dia Compe model 188's are the first reverse pull levers used on TTs because they were what were available at the time. Hey 'nutz, the fact that they don't have a return spring doesn't bug you? I know that the only spring you need is in the caliper, but methinks it would be weird to not have the lever return when you take off the pressure. Anyways got a set of gently used carbon 200tt's for $25 on the 'bay last week.
