2007 Shimano pRon. beware rodie types, contains MTB bling as well.

i actually odnt like SRAMS shifting system which is why i went with dual control. ( IMHO rapid fire and rapid rise dont mesh very well, but rapid rise and dual control are excellent) .

what was wrong with the old trigger systems? i think they were much more intuitive and easier to use than SRAMS shifter gear, why copy somone else instead of having your own neiche.
