A no comprimise answer to the question of a fat bike specific rim. The ARC 35 rim with a 35mm internal blurs the line between a wide mountain rim and Plus rim and is at home in either application. The ARC 40 is a true Plus rim with a 40mm internal rim width but in a lighter package than the ARC 45 which is the widest rim Easton makes and at the upper spectrum of Plus rim widths. A deep rim profile gives resolute performance and stiffness where others fail. This is not a simple size increase, this is a full re-think. And from that rethink, an optimised rim extrusion with great weight saving and Easton durability.
