Bicycle crank arm and chainring carrier assembly

A crank arm and chainring carrier assembly, comprising:

• a crank arm having a plurality of crank arm holes formed therein;
• a chainring carrier having a plurality of carrier holes formed therein, at least two of the plurality of carrier holes formed with an angled section;
• a first pairing feature including a first wall forming an exterior profile formed on the crank arm and a second pairing feature including a second wall forming an interior profile formed on the chainring carrier to position the chainring carrier on the crank arm;
• a clearance defined between the first wall and second wall when the first and second pairing features are paired, the clearance substantially inhibiting torque transfer between the first and second pairing features;
• and
• a plurality of fasteners, at least two of the plurality of fasteners having an alignment feature formed thereon to cooperate with the corresponding angled section of the chainring carrier holes to align and connect the chainring carrier on the crank arm to form a torque-transmitting coupling of the crank arm and the chainring carrier and to maintain the clearance between the first and second pairing features.
