About This Product: Answer Mini Crank Arms

Light weight machined aluminum crank arms with aluminum 5-bolt 110mm spider.  Available in several sizes from 125mm to 165mm.  One of the lightest arms on the market, the Answer crank has been reinvented. The highest strength-to-weight ratio of any mini crank on the market.

J&R Helpful Hint:  This crank set requires a square spindle bottom bracket and typically needs a 113mm length.  You will need a crank arm puller for these cranks (and to possibly remove your old cranks) that works with square spindles.  You will usually use the short chromoly or standard alloy chainring bolts (unless you use Profile or some other thicker chainring).  As with all 3-pc cranks they require 9/16" pedals.

Weight: (white option adds a few grams to each size due to the weight of powder coating - weights are based on the black anodized arms and spider)

How To Measure Your Inseam

  1. Start with a pair of pants you already have that fit you well and lay them flat on the floor.
  2. Carefully measure the length from the crotch seam to the bottom of the leg.
  3. THIS NUMBER IS YOUR INSEAM. Use this number to help you choose your cranks.
