SRAM X01 Annouced

by Brian Mullin on August 1, 2013

The not very secret SRAM X01
group has been officially announced to the world today, and the new
brethren of the XX1 are cheaper ($200 less) and has the same basic technologies and
designs, with some subtle changes and alterations for cost savings.
While not exactly inexpensive, it does decrease the cost for entry to
the SRAM 1×11 drivetrain system, with only a small weight penalty. A 1x system offers simplicity (no front derailleur, less clutter), decreased weight, less dropped chains, easier frame design (especially for FS 29ers) and stronger chains. 

In a nutshell, in direct comparison to XX1, the crankset uses a
different BCD, a less sculptured rear derailleur and chain, shifters
with aluminum cable covers, and a cassette with a new durable coating.

crankset uses carbon fiber crank arms and an aluminum spider, but
forgoes the more expensive to produce XX1’s 76mm BCD (bolt circle
diameter), and goes with a 94mm BCD. Unfortunately, this conversion
means there’s no room for a 28-tooth chainring, so they’ll only be
available in 30, 32, 34, 36 and 38 sizes, but it does mean they’ll now offer an optional chainring guard option. The CNC machined aluminum chainrings use the X-SYNC tooth
profile for better chain control and retention. The cranks will come in
red and black, 170 and 175mm arm lengths, BB30 and GXP bottom bracket
options, wide and narrow Q-factor, weigh around 655 grams and retail for
$279 (no chainring or BB). The chainrings will retail from $98 to $127, depending on sizing.

29er riders and those that like low granny gear ratios, the loss of the
28-tooth chainring is a big deal, so you might see many people using
the XX1 crankset with the rest of the X01 system.

  • New patented X-SYNC™ tooth profile provides maximum chain control
  • Carbon arms with forged aluminum spider
  • Chainring guard option
  • New spider design allows for easier ring changes
  • CNC- X-SYNC™ machined rings (30-32-34-36-38)
  • Colors: Red and Black
  • Weight: 655g (with BB)

X01 gets all the XX1 technology, including the X-HORIZON horizontal
parallelogram design, the 12-tooth X-SYNC pulley wheels, carbon-fiber
cage and TYPE 2 rolling bearing clutch. The only difference I can tell
between the X01 and XX1, is some more sculpturing  of the derailleur
body. The X01 rear derailleur comes in red and black, weigh 252 grams
and retails for $269.

  • Large upper pulley offset automatically adjusts chain gap
  • X-HORIZON™ design reduces shift force and ghost shifting
  • 12-tooth X-SYNC™ pulley wheels
  • Carbon or aluminum cage
  • Sealed cartridge bearings
  • Colors: Red and Black
  • Weight: 252g

X01 shifters gets an aluminum top cover instead of the XX1’s carbon
fiber, but they still use the X-ACTUATION shifting and Zero Loss Travel
design. The X01 trigger shifters comes in red and black, weigh 91 grams
and retail for $139.

  • SRAM 1X™ X-ACTUATION™ for precise and dependable 11-speed performance
  • Zero Loss Engagement for fastest shifting
  • Multi-adjustable trigger shifter
  • MatchMaker X compatible
  • Aluminum cover and adjustable forged aluminum pull lever
  • Includes discrete clamp
  • Colors: Red and Black
  • Weight: 91g

X01 Grip Shift gets an aluminum cable cover instead of the XX1’s carbon
fiber, but they still use the X-ACTUATION shifting, SPEED METAL shift
indexing and ROLLING THUNDER ball bearing technology. The X01 Grip Shift
comes in red and black, weigh 143 grams and retail for $139 with the
JAWS lock-on grips.

  • SRAM 1X™ X-ACTUATION™ for precise and dependable 11-speed performance
  • SPEED METAL™ shift indexing
  • ROLLING THUNDER™ ball bearing technology
  • JAWS™ lock-on grip technology
  • Aluminum cover
  • Includes lock-on grips
  • Colors: Red and Black
  • Weight: 143g (clamps, cable and JAWS™ lock-on grip)

X01 cassette uses a new dark finish, which is supposed to be more
durable and long lasting. They use the same XX1 manufacturing technique
to create the cassette; they CNC a solid block of 4130 chromoly steel
into a 10-speed system, and then pin on a 42-tooth cog. The X01 X-DOME
cassette has the same 10-12-14-16-18-21-24-28-32-36-42 gear ratio as the
XX1, attaches to the XD driver body, weighs 275 grams and retails for a
whopping $399.

  • Unique finish for high durability
  • 11-speeds (10-12-14-16-18-21-24-28-32-36-42)
  • XD™ Driver Body creates more stable hub connection
  • Optimized Gear steps across entire range
  • Weight: 275g

X01 chain uses the same HARD CHROME plating and hollow pins as the XX1,
but doesn’t have the XX1 weigh saving cutouts between the pins. The
chain retails for $63.

  • New 1X™ specific chain
  • HARD CHROME™ technology for maximum strength and wear resistance
  • Proprietary link finish provides improved life span
  • 11-speed power lock
