Toot Engineering showcased its new custom-made 3D-printed road bike at Eurobike, with the new Eris said to provide dynamic comfort without sacrificing performance.

The Eris features a full 3D-printed, hand-welded construction, made from powdered titanium, and has an almost organic shape.

Toot has its roots in track racing, and the brand debuted with its X23 Swanigami bike at the 2023 World Track Championships in Glasgow.

Erika Marston, co-founder and general manager of Toot Engineering, says: "Everything that we do comes from the track, as this is where we start developments and do tests – from there we do technology transfers and find solutions."

While there is something very Graeme Obree about Toot's track bikes, the new Eris looks very refined and classical in its finish.

The brand says each element of the bike is dimensioned for a function of controlled absorption and deformation.

An interesting omission from the frameset is the lack of a seatpost clamp; instead, the bike uses shape memory built into the metal, which expands when heated and contracts onto the co-developed Gelo seatpost.

The transition temperature for the seatpost system is around the 70° mark, which Toot says is reached using a heat gun.

The bike we saw at Eurobike had new Hourglass wheels, which Toot designs and manufactures, with the brand saying their shape is the result of an aerodynamic study that involved NablaFlow tests to improve drag reduction while maintaining control.
