Debonair name was used in Solo Air Lyrik and Yari forks in 2018. We call this Debonair V1. Debonair V2 was introduced for MY 2019. It features shafts with higher negative air volume and lower friction than previous Solo-Air air spring shafts. Visible differences are the red flat seal-head, plastic moulded grey or black piston and removable shaft foot. This bigger negative volume and lower friction gives you better small bump response and lets you run more air pressure for more mid stroke support. They are a bolt-in upgrade, but only fit solo-air forks. Debonair V2 shafts are also available in different lengths if you want to change your fork travel. Select the correct one for your forks.
These are available for self-install or can be installed as part of a Shockcraft service.
