i'm pondering getting a rack trunk instead of panniers now. is kickback when your heel hits the pannier? on my old bike i had panniers and if i set them up all the way pushed back i didn't get that otherwise it was a problem. the new bike i will be getting soon will fit me! but i am short i suspect the bike being a lot smaller to fit me may make it harder to find panniers that i can ride with. also the rack trunk i found is really pretty! and i think is big enough to hold what i would need to put in it
