Alright well i was running through my gears earlier to test how long the up/down throws are. Then all of a sudden i heard a snap from with in my shifter (sram x-7) so i made sure it wasnt working (it sure wasnt) so i took it apart to try and repair any possible damage... obivously was unable to (as my sig says im a noob lol) so now i have to buy a new one, should i just buy a new single shifter to replace the broken one? or should i buy a front and rear one? considering the questionable relibality of this praticluar shifter (not the model but the shifter it self may possibly be defective due to how it happend to break) to sum it up im looking for 2 things, should i replace both shifters or just one? and if so what shifters should i look into?
