That’s what i ment by P clips,but i don’t know if they’re good for very heavy loads,it could depend on how much you’re carrying.
I’m no expert,but i thought something might be less likely to go ping with a not very heavy load and P clips. It could depend on how much you’re carryig though.
In Cycling Plus the Kona Sutra does have a similar bodge to that on the left hand side,and the testers didn’t really like it. It had a very long bolt and they thought with heavy loads it could put a lot of weight on the end of the bolt,and possibly cause it to fail.
If it was me i’d get a hole put in at the bottom of each seatstay and use those to mount my rack,but i probably worry about some things more than i need to occasionally.
