Am I the only one who's thinking/ trying this? On a Saturday afternoon I am throwing caution in the wind! I have weeracerweenie who's kindly gonna help me modify my 2012 10 spd RH STI to go 11 spd.


1. So far I can verify that the RD can easily move another 2mm toward NDS without running out of low stop screw - check
2. Assumption - YAW FD may get rub in big-big & small-small. I sometimes hit big-big under pressure racing but not fussed bout small-small rub-age! As I have a quarq S975 PM it may pay to get the red 22 chain-rings in future.
