I've been riding profile cranks for close to 7 years. I think i bought my first set when i was in 8th grade, and rode them up until they bent inwards 5 years later. I bought left hand drive arms and a ti spindle after that and have not had too many problems, other than where you tighten them, the metal on the cranks bent inwards so i can't loosen the bolt. But other than that they're tough cranks and have lived up to their legendary name.
