right.. i just bought a pair of the red heatsink pads with the CNC V backings and they have no hold and i have grinded my rim so harsh that it would probably destroy some other kinds of pads. another thing is after 2 days of riding one of the pads fell out of the backings . I am very disapointed because i have heard soooo many good reports on these pads and this has happened. can anyone tell me where i stand?
