Von Hof Cycles is small bike company based in Hoboken, New Jersey that contracts American builders for its frames. Although based on the East Coast, we have seen Von Hof frames in the wild as far away as China when Kathryn Cumming raced one at the UCI races held there

Last week, Von Hof held a release event for the Columbus steel ACX, its newest cyclocross/gravel frame. Today, we take a look at the new American-built steel frame via the press release below.


On August 1, Von Hof Cycles released the ACX, a new line of American-made steel cyclocross frames. The geometry of the ACX is modeled after the race-inspired geometry of the aluminum AL Cyclocross frame. The race-inspired geometry makes the ACX a choice for either cyclocross steel enthusiasts or riders looking for a sturdy build for gravel and off-road adventures.

The ACX is built from Columbus steel tubing and features a custom-designed proprietary top tube designed for shouldering comfort. The front fork is an ENVE CX disc fork with a 12mm thru axle and the rear features a 142x12mm thru axle. Quick release forks are available upon request.

The ACX meets its gravel mission with clearance for 40mm tires and the rear is set up for flat mount disc brakes. The bottom bracket is a T47 and the head tube is tapered.

Full pricing on complete builds of the ACX will be released in early September, and frame production is expected to be complete around November 1st.

Von Hof held a launch party Thursday, August 3rd to celebrate the release. In addition to unveiling the new ACX frame, small batch builder Carl Schlemowitz from Metal Guru / Vicious Cycles was on hand to talk about Von Hof’s newest cyclocross offering. Von Hof-sponsored cyclocross racer Kathryn Cumming of Jalepeno Cycling and Ritchey Logic, whose build kits Von Hof will be offering on complete bikes, were also featured at the event.
