FFS I've been at this for over an hour. Previous Dia Compe shifter fell apart during my last race, obviously three times outdoors was too much for it. And made for an IM70.3 UK 'interesting' bike leg. All easy so far...despite having to replace the nearly new gear cable as well...then shifter no.2... It just *will not* go back together, (per image 2) after installing the base into the bar. Its busting the cable too. F. F. S.
