Answer Question
Yes, the 110mm brakes will fit on Head Cyclic 181 skis. They will be a little tight fitting and the plastic of the ski brakes will catch a little on the edges of the skis, so you will want to bend the brakes out slightly. To bend the brakes, you can use a metal pipe (like a bike seat tube, or mountain bike handlebar). Just be careful when bending the brakes so you don't break the plastic on the binding.
