I have gone for a 46/34 combination but the front mech is meant to be used with a 50T ring.....The rings are both Shimano , the rear mech is a 9 speed 105 and the shifters are downtube Shimano DA SL-7700. Any suggestions as to which front mech i could get?....My choice would be the Shimano CX70 mech but the blurb says best with STI shifters....Would this 10 speedfront mech work with 9 speed DT shifters.....if not any suggestions for a suitable front mech....does even need to be Shimano?
