Double Elipse Rocker – The two elliptical curves at the waist and at the curve of the rocker work in tandem. Depending on the effect of pressure placed on the binding area, you get varying edge length ideal for each situation. This guarantees optimal edging on icy steep terrain without losing the playful lightness in turn initiation and control.

2mm Camber

Single Radius Shape – Harmonious sidecut to guarantee balanced skiing qualities among a wide range of use.

Ride Tip – The special carbon core in the shovel ensures an effective reduction of mass and an optimization of vibration and damping properties. The resulting smoothness without chatter -- especially in changing snow conditions -- delivers perfect precision in turn initiation and dampens impacts like a shock absorber.

Ash-Poplar Ride Core – By combining the high strength of ash with particularly lightweight poplar, Dynafit created a highly responsive core with outstanding damping properties and rebound without giving up lightness. This has a particularly positive effect on power transfer to the edges and cuts down on chatter at high speeds.

Carbon Speed Stringer – Carbon stringer enhances the ski's performance at speed.

Full ABS Sidewall – Impact resistant ABS along the full length of the sidewall for durability and precise edge control.

Skin Attachment – Patented SpeedSkin attachment is built into the ski - it's light, secure, and easy to de-skin without removing your skis.

We recommend a brake width equal to or at most 15 mm wider than the ski waist width.

Radical Toe Piece – Cast alloy baseplate and forged steel toe arms with hardened pins

Side Towers – New Side Towers aid step-in entry and reduce chances of pre-release from lateral shock.

Four screw mounting pattern rather than the traditional 5 hole Dynafit pattern

Crampon Slots – Reinforced crampon slots in baseplate for ski crampons.

Alloy pivot post with polymer body and stainless steel heel pins

Release – Lateral and Vertical release both originate at the heel, and release values are set with separate screws.

Speed Step Climbing Bar – New design climbing bar is super easy to adjust while skinning using a ski pole.

Anti-Twist Device – 2014-2015 Speed Radicals include an anti-twist device that keeps the heel from rotating inadvertently into ski mode while skinning.

Toe lever should be in locked position for skinning.

Tour mode is accessed for all positions by rotating heel 3/4 turn counter-clockwise (heel pins face user's right). Height adjustment is done by flipping the Speed Step Climbing Bar up or down as needed. On the fly adjustments with a ski pole are simple and precise.

Heel should be rotated counter-clockwise to access skinning mode, and clockwise to return to ski mode (disregard the red arrow on heel top plate).

Tech Soles Only – Boots with tech fittings in the toe and heel are required for use with this binding.

Dynafit Compatible Boots – Boots with Dynafit toe and heel fittings are required to use this binding.

One Size Fits All – Binding can be mounted to fit all boot sizes.

Uses Torx 20 screws instead of PoziDrive #3 screws

Not compatible with ski brakes; Dynafit Guide cable leash included.

Last: 99 mm – Performance fit and above average instep height for average width feet

C.A.S. Shell – Custom Adaptive Shape shells are anatomically formed around the heel and problem areas at the factory. Common punch zones are plainly marked with a dot grid pattern on the shell, and the new polyether and Triax 3.0 shell materials offer improved stability when heated.

Quick Instep – A shaped plastic component at the instep that is softer than the rest of the shell helps you to step into and out of the ski boot.

C.A.S. Grindable Boot Board – The removable C.A.S. boot board offers plenty of thickness for grinding and a grid pattern for reference.

Bootfitter's Notes – The Zero G shells use the same last as the new Cochise line, with a 99 mm forefoot and narrower midfoot than previous Tecnica "average" lasts. Volume around the ankle is much reduced, though the instep height remains fairly relaxed as is typical for Tecnica. The new Triax 3.0 plastic punches well and holds its shape without turning tacky, but care should be taken when attempting aggressive punches at the bi-injection seam line.

Flex: 110 – A stiff flex that's still forgiving enough for narrow chutes, trees and mellow pow days.

Ultrafit Ultralon Liner – Heat moldable liner with Ultralon foam.

Power Light Design – Bi-injected triax 3.0 frame that is 30% thinner and 2.5 times stiffer than conventional boot material. Results in an 18% weight savings without a loss in performance.

Shell – Bi-Injected Triax 3.0 with Quick Instep Flex Zone

Cuff – Light Grid Triax 3.0 with Strategic Cutouts for Weight Reduction

Adjustable Cuff Alignment

Mobility Cuff Walk/Ski Mode – Tecnica's redesigned walk mode features a 44˚ range of leg movement, a super smooth pivot action, and metal-to-metal contact in the locking mechanism. The new S.A.S (Self-Adjusting System) tightens the locking action as the metal wears to eliminate play.

Zero G Buckles – Extra light full aluminum buckles with innovative Lift Lock mechanism and extended cuff hook.

Lift Lock – Innovative Lift Lock system holds the buckles up and out of the way so they don't catch while getting in or out of your boots.
