I was looking for a rack for my new gravel bike that wasn't as wide as previous racks I had owned. This one is perfect-it's burly enough to carry two loaded panniers but it's fairly narrow width wise so as not to protrude far past the frame when not carrying a load. It also looks great. Big fan.
This rack worked perfectly on my Trek Madone 4.2 The off-set skewer bracket does the job getting the paniers far enough back to keep them out of the way of your shoes. Having the weight carried by the skewer resolves potential problems with the carbon frame.
I try to fit a front rack on my e-bike with no good result. So use the rear rack instead, the extra set back helps for heel clearance and fits 700c x 45mm tier with fender on.
