I purchased a pair of Spinergy Flex rims and love them except in about 6 months the rubber has split in many places. So I send them back to Spinergy for $100 shipping and $200 to fix them. I get them back and in 2 months they are split again in many places. I am around 200lbs and work 40 hours in an office and not really abusive on them. So I'm sick of that shit and just want to put good handrims on a set of good wheels. So I get to looking and there are not any holes drilled in the rim to mount to. Has anyone had this experience or should I just take them to a bike shop and drill them out?
