Ion CX packs a race bike pedigree and loads of performance into an aluminum Cyclocross chassis. Ion is equally at home on the course or on the commute, in any conditions.


200 Series Alpha Aluminum

Trek's premium road alloy, formed into sophisticated tube shapes for maximum strength and minimum weight.

E2 head tube and fork

E2 head tube tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the lateral rigidity of a 1.5" system without the added weight.

Crown-mounted housing stop

Isolates the brake cable from steerer tube flex, significantly reducing chatter for better braking performance in all conditions.

Gary Fisher Collection

Innovative bikes imagined by Gary Fisher, built by Trek.

BB86.5

Wide, stiff bottom bracket improves pedaling performance for exhilarating acceleration.

Vanishing fender mounts

Frame is fashioned with discreet fender mounts so you can ride all year long.
