The newest generation of track crank from Spécialités T.A. -

• 130 mm. bolt pattern chainrings
• 165, 170, 172.5 or 175 mm crank lengths
• 1/8" chainrings available from 44 to 52 teeth
• Includes crank bolts and pedal washers
• Bottom bracket spindle recommended by manufacturer: 103mm., symmetrical, with ISO tapers.

  NB: I encountered chainline issues (several mm wider than the common track standard) with this crank, even when used with TA's own bottom bracket. Caveat emptor.
