Bicycle Crank Shortener – 1/2 inch pedal bolts

Description Replacement 1/2″ pedal bolts for use with our Crank Shortener when the original crank uses 1/2″ pedals instead of 9/16″ pedals.  1/2″ pedals are more likely on some old models of stationary exercise bikes and some kids bikes. Note: the crank shortener pedal axle holes are 9/16″ so you will not be able to attach 1/2″ pedals to the crank shortener.  You will need pedals with 9/16″ axles/spindles These bolts are used to attach the crank shorterner to the existing crank arm, through the original pedal hole. Two Versions You will want the one that matches the style of crank shortener you are buying. The single-threaded bolt  (per side) The 2 part: flange bolt (per side) Note: Sold as a pair. Note: Cannot be exchanged for the standard 9/16″ size that comes with the crank shorteners.  These are an add-on purchase.
