Answer RC lightweight locking wheel nuts

The new lightweight locking wheel nuts from Answer RC are now available. Designed to offer the best of both worlds, security and performance, the security aspect is two fold. Firstly the have a knurled section machined into the back of the nut to allow it to lock onto the wheel and secondly the nuts come with O Rings that seat into the back of the nut to secure the nut against the wheel stub axle and prevent vibration loosening. The nuts come with 8 o-rings giving you a complete spare set. The nuts are machined away on the faces and drilled into to save weight and as with any closed cap wheel nut, knowing that the stub axle will not get mangled up is always a welcome benefit. Available in red and black in both 1.0mm and 1.25mm threads.
