TENSPEED HERO Due to the support of Tenspeed Hero cycling blog, the frame utilizes the company’s brand language, based on the color palettes of Ellsworth Kelly.

FINISH PALETTE

IN STORES Treble would provide a package deal with bicycle retailers that includes the frame, dropouts and one set of components. The user could then exchange these components for a new set at any given time with the aid of bike shop employees.

EMOTIONAL BENEFITS This could encourage less experienced users to try out the system. By allowing the shop to swap parts, the customer can watch and learn from an expert without feeling intimidated by the responsibility of correctly applying the components.

LIFESPAN Common frame breaks are located in the dropouts.

If this piece is detachable, the dropout can be replaced without buying a new frame.

3 FOR 1 The monetary investment is reduced by nearly a third due to the need for a single frame as opposed to three.
