New E*Thirteen Chain Guide

by Nathan 13

E*Thirteen have launched their revolutionary new XCX  – Xc and Cyclocross specific chain guide.

The XCX is an XC chain device designed to be used with a single front chain ring and with either a 9 or 10 speed cassette at the rear. Its lightweight design means you can drop your chainrings down to one and take off your front mech and front shifter further saving weight.


With a reputed weight of only 56 grams, the device is super light and has been designed by former World Cup mechanic Jonas Mikolayunas. Having won the Men’s Elite Silver medal in the 2009 UCI World Championship Cross Country race the XCX is the first chain retention system in the world to podium at an international World Cup XC event.

The chain device retails at £39.95.

  1. wonder how these compare to a full guide?

  2. can you run it with a bash?

  3. Looks slightly tidier than the MRP equivalent
    2-6g less, same RRP. Still expensive though

  4. Why is everyone obsessed with fecking cyclocross lately?

  5. I can see it being a top fit for XC racing, but not really for ‘cross. Surely a road/’cross bottom bracket doesn’t use BB spacers – so how’s it going to fit?

  6. external BBs still use spacers, even on cross/road applications

  7. not sure where the reference to cyclocross came from???

  8. Slowrider – from here “E*Thirteen have launched their revolutionary new XCX – XC and Cyclocross specific chain guide.”

    My ‘cross bike doesn’t have BB spacers. Perhaps I’ve put it on wrong 🙂

  9. Chipps: if you switch from a road to mountain bb it should fit. Road cups are wider. I like my MRP X.1. The only problem is if you do manage to spin it round the bb, it’s very hard to move it back. This now looks like it’s got less diddy bolts than the mrp, which I like.

  10. ah yes, right at the top in plain view, no wonder i missed it 😛

  11. At last, I’ve been trying to get hold of one for ages without success, must be because it appeared on their website months before they started selling it !!

  12. Anyone else think that this, and the MRP chainguide, are horrendously overpriced? I mean, an SLX front derailleur RRP is £35-£40 depending on model, and surely they are far more complex to manufacture.

  13. tidy looking but wallet rape for sure
