e*thirteen DH Crank – Finally a lightweight DH crank without strength sacrifices.
• Forged and then machined 7050 Aluminum arms.
o 7050 is 40% stronger than most common hollow forged alloys.
• 30mm heat-treated cromoly spindle.
o It is 200%+ stiffer than 24mm steel spindles commonly used in external bearing cranksets.
• German DIN 32711-P3 Polygon interface provides 100% surface contact between spindle and crankarm
o Eliminates fretting corrosion – the prime cause of dreaded crankset creaking and loosening.
• 14mm pedal thread engagement + 7050 arm construction + quality pedal washers.
o Eliminates the need for costly and unreliable pedal thread inserts.
• High quality titanium-nickel hybrid spindle coating.
o Increases durability and extends material life (to just about forever). Tell your machinist friends. They might hug you.
• Standard 104 BCD
o Of course!
• Lengths:
o 165mm, 170mm and 175mm lengths.
• BB:
o Larger BB 6806 (7×30x42)Bearings carry 20% greater static load and dramatically increase BB durability.
o 68/73mm and 83mm BB shell versions.
• New: 24-38 Shift ringset option available.
o For you core freeriders who like to earn your downhill.
o Inner ring bolts to outer ring requiring no inner ring tabs on crank.
• Weight: 870g: Crank weight: 759g (165mm x 83mm) / BB weight 111g.
• MSRP: $349 w/BB and BB install tool.
Ring Configurations

• 24-38 shiftrings: 9 & 10speed compatible. The 24T chainring bolts directly to the 38T chainring to optimize tooth location and provide the greatest amount of modularity and compatibility seen in a heavy duty All Mountain / race weight DH crankset.
