MONDIAL: One frame to do it all.
Designed in Montréal by Atelier Olympia, the MONDIAL frame is built from butted steel and modern standards to create a durable, versatile platform. It can be built as a full steel touring or commuting bike, or configured with a carbon fork for a lighter, faster gravel setup. One frame, multiple lives.
Designed for:
- Daily commuting and year-round use
- Long-distance touring and bikepacking
- Gravel riding and mixed-terrain exploration
- Riders who want one bike instead of many
