I got lucky with drops from an old steel Ross 10-speed; meaning: they were the right diamter to flip the Rapidfile shift/brake combo. I did have to replace the cables and housings too because the flip requires more cable looped up front by the bars. Also the steerer extender was a must for me. I am 6' tall with 34" legs.
Now I'm thinking about how long these Rapid fires will last and what would berequired to swap with other levers and shifters and do I have to change the brakes then. I'm thinking this setup should last the season. Hope I'm right! :-)
