XX1 Crank, GXP 168 Q-Factor

1x drivetrain dedication by design, this is SRAM's XX1 line. Simple. Light. Durable. Less is more.

The centerpiece of SRAM''s XX1 line for dedicated 1X componentry. Simplicity means greater overall durability, lower weight, better drive management, and precise shifting.

A single universal spider to fit the six (28-30-32-34-36-38) available X-SYNC rings, available in wide and narrow Q-factors, and available for BB30 and GXP. Maximized chain control.

• X-SYNC: precisely CNC-machined wide/narrow tooth alternation around the entire chainring for an optimized fit to the chain''s inner and outer links.
• BB30 offers weight savings, narrow Q-factor for greater clearance, greater bearing durability, and a stronger crank. GXP provides improved performance and overall feel due to reduced friction, weight, and durability.
• Weighing in at approximately 650g with BB (BB NOT INCLUDED)
• Forged aluminum spider with carbon arms

What does "Q" mean? Q is short for "Q-Factor", which is the distance between the planes where your pedals attach to your crank arms-- measured as a line parallel to your BB axle. What Q-Factor you need is determined by your frame, which may require assistance to confirm. Feel free to give us a call (734 484 9999) if you''re confused, but most often the bike needs to be seen and measured. Conventional cycling knowledge recommends using the narrowest Q-Factor you can fit, obviously without running into stay clearance issues.
