Alligator Serration Disc Brake Rotor
Alligator Serration Disc brake rotors are engineered to have superior strength, and to dissipate heat quickly.
Due to manufacturer restrictions we can only ship this item within the U.S.
Bought this to replace the stock Avid rotor that came w/ my Elixirs. I was getting the dreaded "turkey warble" sound and bad shuddering under hard braking. Nothing would fix it--sanding the rotors, new pads, re-bedding, etc. Bought the Alligator rotor based on some web reviews that said it was a good fix for the problem. Success--works like a charm. No more noise--just nice/smooth, quiet braking with no shuddering. The rotor does seem a little thinner that the Avid rotor, so it took several stops before the calipers adjusted themselves. But once broken in they feel great. I assume the thinness means it won't last as long either, but for the price who cares. I can't tell a difference in braking power--seems the same. Better modulation since the shuddering has disappeared. Great price--no complaints.
Looks cool and doesn't create the turkey gobble noise but they don't stop as well as the Alligator Wavy rotors. On the plus side, the braking power is very consistent whether you're on slow cross country or bombing down long hills. The Wavy rotors feel like they get more touchy when they get warm. These don't seem to glaze the pads as fast as Wavy rotors either.
Great price and look but I tried this rotor alongside the stock avid rotors and noticed increased pulsation due to the shape and less braking power. I expected it due to the reduced surface area.
Used these per recommendations that they would eliminate Avid brake turkey gobble and vibrations on my Specialized Stumpjumper. Worked like a charm. Over a year on these and they have been trouble free. I will say that they eat pads due to their shape, but I will take it for the silence!
Excellent rotor for the price. Lightweight, Easy to install, Good stopping power, looks great too.
