e*Thirteen recently released their new XCX pro chainguide.  It has cam-assisted chainline adjustments and a sweet white color to match all your other fresh new white components.

Wondering what’s up with the *prototype disclaimer on that image?  Well, sharp eyed downhillers will note that a seat tube mounted chainguide isn’t the most common thing on the trail.  This was a CNC machined one-off made custom just for Julien Absalon’s Orbea XC world championship race bike.  Seems he didn’t need the little ring on SRAM’s new XX 2×10 to take the podium:


JHK’s apparently a fan, too, and cyclocross racers are jumping for it.  In fact, it’s the first chainguide to ever make the top of the podium at a World Cup race!  The current production version (which launched in November) uses the standard BB mount and is shown after the break with specs and pricing…


The e*Thirteen XCX BB-mount chainguide retails for £39.99 (guessing about $50 US??) and has the following specs:

  • Extremely light at 56 grams!
  • World Championship gold medal-proven top slider design
  • Easily change chains and chainrings w/o removing wearplate
  • Captive gold anodized alloy hardware
  • Wearplate has chainring size indicators for simple adjustment
  • 1.5 mm backplate spacing with provided 0.5 mm spacers allows perfect setup
  • Gear range of 32T – 42T, small enough for the steep Mont Saint Anne climbs and big enough to win Glouchester, Massachusetts!
  • Available in black or white
  • Made in the USA

I’ve been using the MRP X.1 BB mount all summer and it’s been great. I’m glad to see both E.13 and MRP are releasing seat tube mounted versions. It’ll be much easier to dial them in as well as keep chainlines in check as compared to the BB mount.
