This is a Cane Creek Invert CS gravel suspension fork with Climb Switch that was used in our shop strictly as a demo display fork. It was professionally installed on four bicycles to showcase fit and ride quality, then removed and cleaned each time. Total ride time is approximately four weeks.
The fork is extremely clean and mechanically sound. This is a lightly used demo unit—not customer-owned—and is being sold as a shop demo at a reduced price.

Service / Ownership Context
This fork requires routine suspension maintenance like any air-sprung system. Cane Creek recommends a splash oil flush every 50 hours and a full service every 100 hours. The demo unit has minimal ride time and has been shop-inspected. Installation and air-spring setup are shop-recommended to ensure correct steerer length, brake alignment, and rider pressure.

- Good fit for riders wanting front-end compliance on rough gravel
