An economical way to keep the older Truvativ IsoFlow and newer Truvativ 5D cranksets on the road. I used mine to replace a rounded out crank arm that had been pushed a little too hard on it's steel bottom bracket spindle. Considering I put over 5000 miles on my crank it was worth the twenty bucks to save me the money of buying a whole crankset. Tighten to 28-31 foot pounds of torque and you're good to go!
PROS: It Fits, Easy To Install
CONS: Limited Compatibility
BEST USES: Casual Riding, Saving Money, Mountain Biking
I have had to purchase two of these left crank arms because they were breaking. These are not compatible with normal square taper cranks, they are specific to this crankset. The first broke along the spindle interface, it cracked in half. The second stripped out even though the pedal was tightened with a torque wrench. If you're buying this part, think about a new crankset instead.
