heya!

current setup.
sram rival front and rear derailleur
sram compact crank
sram 12-27 cassette
kmc chain

i was at the bike shop recently and everything seemed to shift perfect.

maybe im shifting incorrectly. but i noticed if im in small ring but middle"ish" in the front der doesnt want to throw the chain on big ring. on some rare occasions it has worked but after this test run and one dropped chain im hesitate...its not much a problem when shifting up front when im on small cogs in the back though. i rode on hilly terrain however on flats, this is when it dropped while shifting up front.

please advise on a correct shift method. in small ring i shift up big ring, then 2 up in the back? i've read this before but i guess with more experience in shifting and practice it will help?

is this common for compact cranks? also should i get the sram f/d that is equipped or comes with a chaindrop guard?

its a pain in the butt. i swapped out my standard crank for this compact, and all these problems arise....ugh

thank you for any advice guys/gals!
