I am starting to get into the habit of cycling to my job which is a solid 5.5 miles one way, but they require a decent dress code. I have a backpack that I can carry the change of clothes in, but my back gets sweaty af and the cycling clothes don't get the chance to dry off while I am at work, meaning the shirt is still damp and smells like shit. To get around this, I am looking at a bike rack, a Topeak Explorer rack specifically, because the local bike shop has one on hand for ~$55 (same as online equivalents). Is this a worthwhile rack for something as bulky as a backpack, or should I look at a different rack/try to shove the change of clothes in a duffel bag?
