This warning is on the fork of my wife's Norco CCX cyclocross bike.
This fork is only to be used for normal road riding. It has not been designed to withstand the stresses of off road riding. Use of this fork off road is not safe and could could cause sudden and catastrophic failure. For more information, please contact your dealer.
A cyclocross fork that is unsafe for off road use, what is the point of that? At least Norco is honest that their carbon forks are junk.
