griffons are fine if you are lighter rider, and not so hard on your gear. my bud is 150 punds and 6 feet tall and he has no problem with them. even my dad has these on his pipecleaners and he has not broken them.
I MAKE CUSTOM DIECUTS, LOTS OF COLOURS TO CHOOSE FROM AND CAN MAKE ANY SIZE YOU WANT. PM ME FOR PRICING ETC.
I didn't fix your brakes, but i made your bell louder - e flip
