I am continue to plan the build of the JT tandem; I am thinking a 12-36T 9 speed cassette at the back with a 53-32T double combination at the front. Is 53-32 too big of a jump for a FD to handle?
50-34 is the standard compact double. Our T50 works fine with 26-44-54 triple.
It will be set up with the 53T chainring aligned with the middle cog in the 9 speed cassette, and the 34 only used as a bailout on steep grades, and only with larger 4 sprockets at the back. The upshift would not have to quick.
And facts? Opinions?
