i have a trek trunk bag with it's folding side panniers, problem they are not big enough (as 11"x11"😉 i want to store in one of them a small laptop (12" screen) with it's a bag. the laptop itself can not be fitted EXACTLY inside one of them, however i would want to store the laptop inside a case. i thought about getting side panniers alone, but i'm always afraid they might be detach/fall off the byciles as they are not firmly secured to the bycicles... i use the main compartment to house a the chain and a bike cover, so there is no room for more (even if there was i would still be too small). i can't carry it on my back becouse it can give back aches.
