  • A handy workshop time saver that makes determining the BCD of a crank or ring a cinch.

  • Simple to use; just put the pegs into the mounting holes or chainring bolts of the crank or ring you want to measure and the indicator arm will highlight the correct 4 or 5 bolt standard.

  • Anodized and permanently laser etched for a long life.

  • Includes a centre to centre distance scale and reference chart for measuring other mounting pattern dimensions.

  • Made in the USA and covered by Park's legendary limited lifetime warranty
