To me this is unneccsary wear on the meniscus, why put the extra strain on it. A fluid stop without a brake can be achieved, but at what cost, is all the additional grinding neccessary. I love my fixed gear, its a great ride and i enjoy the benefits, but i am not so sure i want to add to potentially cripling list of geriatric ailments.
