hiya folks,
i'm after a bit of advice if you'd be so kind.
a few months back i purchased a B'Twin 5.0 RockRider mountain bike.

now i'm thinking of changing the gear shifters as i've found that the 'gripshift' system already on it is too unstable for what i want... i slight unintentional twist of the hand whilst riding and the gears will jump down without a second thought......
the bike is fitted with a Shimano TZ-30 front derailleur,
a Shimano Rear Derailleur - no numbers on it, just the letters SIS
and SRAM MRX 21-speed (3x7) grip shifters,
oh and a Shimano TZ-21 freewheel
i would like to change to the Shimano ST-EF51 shifters......

now my question is this...will the EF-51 work with the rest of the derailleur set-up ? or will i have to change other parts ?
many thanks for any replies.
