FondTF2 Posted May 12, 2021 Share Have recently changed over from an Ultegra Crank to a FSA Kforce Light crank. Having followed the installation guidelines for a BSA frame fitment, there is a gap between the BB and the left crank arm where the wave spring washer is. (see pic) Would I need an adjustable spacer as well? Link to comment Share on other sites More sharing options...

RobertWhitehead Posted May 18, 2021 Share The BB has a spacer that you need to add between the cup and crank arm Link to comment Share on other sites More sharing options...
love2fly Posted May 18, 2021 Share Many would disagree but 2.5mm spacer each side and NO WAVY WASHER. Wavy washer is only for PF BB. THE drive side bearing also has the plastic insert taking from 25mm ID to 24mm Link to comment Share on other sites More sharing options...
