Tech Specs:

• Headset Size:
  1.1/8"
• Seat Tube:
  Some XC-2s use a 31.2mm ø post, others accept a 27.2mm ø post.

• Rear Pivot
  Use #6902 bearings. These are available from BETD in the UK.

• Disc Mounts:
  Most are International Standard (51mm Centre to Centre).
  More Info...
• Bottom Bracket:
  It uses a 68mm shell / 110mm axle. I believe the axle length can vary according to what cranks/chainset you are using - mine is fitted with Shimano LX chainset. You can buy a BB from Wiggle.
• Bottle Mounts:
  There aren't any. Buy a CamelBak or similar hydration pack.

• Replaceable Mech Hanger
  Is the same as the one found on the 1999 Claud Butler Merak. I bent mine and it turned out to be the same as one on the Claud. More info coming soon...
• Rear Shock Mounts:
  Shock Eye to Eye length is an unknown quantity. Mine is 190mm, it seems others are longer.
  More Info...
• Multiple Shock Mountings:
  At the front end of the shock (where it meets the mainframe), the mounting the shock in the upper position offers a slacker head angle (slower steering, more stability), and the lower one offers a steeper angle (quicker steering, twitchier handling).
  At the rear (swingarm) end, the lower mounting offers a bit more travel and the upper gives you a bit less.
  Experiment to see which works best for you - but beware, some combinations may make the swingarm bottom out on the mainframe near the main pivot, or cause the shock to scrape the bottom of the swingarm mounting.
