Geometry First

Every degree, every millimeter matters and can mean the difference between having an average ride or an epic experience, being on the bike or being at one with it. The Optic represents the next evolution of our geometry philosophy. A new approach that delivers the optimal fit and handling characteristics for every rider, not only for the frame size they fit, but also the wheel size they prefer.

27.5 (650B) & 29" Platforms

No two riders ride the same trail in the same way. That’s why we developed the Optic from the ground up in two wheel sizes, offering the choice between the quick acceleration of 650B or the improved rollover and momentum of a 29er. To make your choice easier, we’ve optimized the geometry of the 29er to share the same fit and handling characteristics of the 650B version. How do you roll?

Testing and Development

The development of the Optic required our largest fleet of prototype bikes to date. In order to validate the fit and handling between the two wheel sizes, each bike in the fleet was carefully outfitted with the same spec to isolate the effects of wheel size and geometry. Test riders rode the 650B and 29” prototypes back-to-back and provided detailed feedback to the engineering team to further refine the geometry to meet project goals.

Reach Plus and Stack Plus

Optimal Fit and Handling

Stem length is incorporated into the bike’s geometry measurements as Reach Plus and Stack Plus to achieve the optimal fit and handling across each wheel and frame size combination. The Optic 29er uses a shorter stem, longer top tube and slightly steeper head angle for extra leverage over the bigger wheels to maintain similar handling characteristics as a 650b bike without changing the fit.

Modern Trail Geometry

Aggressive and Progressive

To give the Optic a unique ride quality, we adapted the aggressive Killer B geometry from our Sight and Range platforms. The result is a short travel trail bike that shares the same handling characteristics as its longer travel siblings in a nimbler, lighter package.

Optimal Weight Distribution

Gravity Tune fixes the front-centre/rear-centre ratio across all frame sizes. This means that a large frame will not only have a longer front end, but a proportionally longer rear end than a small frame. This keeps the rider’s weight optimally distributed over the bike regardless of their height, delivering equal ride characteristics and unrivalled control for all.

An Efficient Pedaling Platform

Suspension kinematics optimized for trail riding to provide the perfect balance of traction and efficiency on the way up and complete control on the way down

Geometry First

The difference is in the details

Every degree, every millimeter matters and can mean the difference between having an average ride or an epic experience, being on the bike or being at one with it. The Optic represents the next evolution of our geometry philosophy. A new approach that delivers the optimal fit and handling characteristics for every rider, not only for the frame size they fit, but also the wheel size they prefer.

650B and 29" Platforms

Offering you choice without compromise

No two riders ride the same trail in the same way. That’s why we developed the Optic from the ground up in two wheel sizes, offering the choice between the quick acceleration of 650B or the improved rollover and momentum of a 29er. To make your choice easier, we’ve optimized the geometry of the 29er to share the same fit and handling characteristics of the 650B version. How do you roll?

Key Features

Everything you need in a trail bike

Trail bikes are all about versatility. They need to be fast and efficient without being afraid to get a little rowdy. To find that sweet spot, the Optic is carefully outfitted with everything you need like a stealth dropper post, aggressive front tire matched to a fast rolling rear tire, custom-tuned Fox suspension and more.
