I saw these things for the first time on last years Paris Roubaix and I had to look them up to see what they were, then was shocked at the cost. I could see if you were racing on the cobbles, but not sure if the cost benefit ratio is quite there for general riders, however, if you feel they are worth it and will give you peace of mind while riding, have at it. Sort of like the peeps that use the Varia, I questioned it until I borrowed one on a ride and realized that I wanted that that peace of mind going forward.

you should learn to embrace change, and mock it's failings every step of the way.
