Description
xCoil-like feel from your air fork, the Vorsprung Secus rewrites your spring curve for better traction, support, and suppleness across every inch of travel.
Stock air forks are built for the masses, but riders who push hard know the feeling: that stiff initial stroke, the mid-stroke dead zone, and a ramp-up at the end that feels more like hitting a wall than using travel. The Vorsprung Secus fixes all of that. Coming out of Whistler, BC, Vorsprung engineered a compact external air can that plugs into the bottom of your Fox or RockShox fork's air leg and completely transforms the spring curve. The result is an air spring that tracks closer to the linear feel of a coil for the first two-thirds of travel, without giving up the weight or adjustability advantages of air.
The secret is a three-stage approach to the stroke. An enlarged negative air chamber delivers a plush, supple feel right off the top for serious small-bump compliance. A proprietary Midstroke Support Valve then picks up where traditional air springs fall apart, boosting mid-stroke spring rate to keep the bike predictable and supported through the chunky stuff. At the end of the stroke, enlarged lower leg volume softens the ramp so you can actually use your travel with standard volume spacers still in play. Reviewers across the board noted noticeably better traction and front wheel tracking on the trail, and the difference is real enough to feel in the parking lot before you even drop in.
At just 130g, the Secus is a fraction of the weight of a coil conversion kit, and it transfers between compatible forks with minimal hassle. It adds no friction to fork movement, uses your existing OEM seals for air and lower leg services, and comes with a 12-month no-questions-asked crash replacement guarantee from Vorsprung. Compatible with a wide range of Fox and RockShox models, this is the upgrade for riders who want to keep their air fork but refuse to leave performance on the table.
Why You'll Like It
You'll feel the difference the moment you drop into your first trail, with your front wheel sticking to the ground through roots and rocks that used to push it around. If you've ever wished your Fox or RockShox fork had the planted, confidence-inspiring feel of a coil without ditching the weight savings and easy tuning of air, the Secus was made for you. It suits riders who are serious about dialing in their setup and want every inch of their fork's travel working for them, not against them.
