Just curious if anyone has tried some 155mm cranks on their Santa Cruz Bullit or Heckler.. Lots of new articles have come to light lately abut this. My buddy swears by them. He just switched ,but rides an analog Nomad... So not much to go by.. I'm 5.5 ft (167cm) and ride medium MX Bullit. Reading that these shorter cranks benefit a shorter rider... Maybe it's just a way for the bike industry to sell more parts to people... (Insert Facepalm here.)lol .. Would love to hear some thoughts on this.. Cheers From Canada.
