I switched from an aluminium Nitto B135 Rando bar to a steel Nitto B125 bar, and had been using a Dia-Compe 188 reverse brake lever in the end of the drops as in the picture below. When I tried to move the lever over, the internal diameter of the bar end of the new steel drops was too big, even though they both have an external clamp of 25.4mm. I am thinking the expander at the end of the lever may have bent/squished in past installation and a new lever might sort this. So the question: would a new lever (£20 for a pair) indeed sort this, or should I find a shim for inside the bars (a la beer can)? Since I remove the lever at the track this would not be a fit-and-forget application so a shim is a less attractive option. Anyone know, or absent facts have an opinion?
