The GnarCore eccentric is an optional replacement for the lower/upper eccentric core on the Ibis Ripley 29.

When Ibis designed the Ripley they made the eccentric core parts as lightweight as possible while still passing all machine and ride tests. With the GnarCore, Ibis have added back a small amount (8 grams) of strategically placed material to make the part more tolerant of over tightening the hardware.

As of January 8th, 2014, all Ripleys have been shipping with a new, beefier lower eccentric core and new Titanium bolt. A side benefit to this added material is that the new "GnarCore" increases the lateral stiffness of the Ripley by 10%. The new Titanium bolt is recognizably different than the anodized aluminum bolts that were being put on the bikes until now. So if you get a Ripley and notice a slight change in the lower eccentric bolt, that's why.

The updated parts can be retrofitted to all Ripley frames.
