While it’s not powered by an Arc Reactor, Stijl’s Iron Man 29er is trick enough to make Tony Stark proud.

Builder Hinmaton Hisler used a multi-step lug process in order to make use of steel tubes that were originally too short at the downtube. It was a happy accident that led to this really beautiful concept bike built for a customer that owns an iron foundry.

This is the first lugged bike from Hisler, so it was a learning process. Rather than risk getting the angles wrong, he went about it differently. He built the complete bike in steel first, sleeving the shorter, smaller tubes into a larger one, then cutting away the appropriate parts to slide the full length carbon tubes into place.

The tubing is Columbus Zona and Spirit with Dedaccaia stays and a headtube machined in house.

Rocker dropouts with a frame break for the belt drive.

The paint was a layered process to create a deep candy metallic finish that was simply gorgeous in person. All told, they have about $8,000 in the bike, with $2,300 of that in the frame.

Stijl’s otherb 29er frame is built entirely of road bike tubes and his own seat stay bridge and brake mounts.
