Dynafit Radical ST backcountry skiing binding.

Dynafit Radical ST backcountry skiing binding, this model first introduced for 2011-2012 season. Main changes over previous are an entirely redesigned heel lift system, as well as metal 'power towers' in the toe that may help with binding entry and possibly help prevent inadvertent release in downhill mode. Sister model to this binding is the TLT Radical FT, only difference being a connector plate between toe and heel, and the ability to set higher release values (12 instead of 10)

Dynafit TLT model of backcountry skiing binding.

Dynafit TLT model of backcountry skiing binding. This model began sales in the early 1990s (the version pictured) and was still in production through 2011, called TLT Speed. The binding has been available in numerous color schemes over the years, all offerings have been nearly identical in mechanical parts. Ski brakes were formerly available for the TLT but are no longer manufactured.

What is the Dynafit binding?
Dynafit is a backcountry skiing binding that allows you to ski downhill with your boot attached to your ski the same way a regular alpine ski binding functions, yet transforms into a touring/climbing binding for skiing uphill or across level ground with your heels free to move up and down. The binding is available in numerous models. The TLT Speed (Tour Lite Tech) has been available for several decades. We have used the TLT extensively and highly recommend it as well as the Dynafit Comfort, ST and FT model offerings, as well as the TLT Radical FT and TLT Radical ST. Note that this TYPE of backcountry skiing binding is commonly called a “tech” binding. “Dynafit” is a brand.

Below, Dynafit models generally available for 2014/2015 season:

– TLT Radical FT (new in 2011, redesigned heel lift & more, heel elasticity added for winter 2014.)

– TLT Radical ST (new in 2011, redesigned heel lift & more)

– TLT Vertical FT (introduced for 2006/2007, still viable, buy with wide brakes and Power Blocks for what’s perhaps the best Dynafit binding ever made. Manufacturing is discontinued.)

– TLT Vertical ST (introduced for 2007/2008, still viable. Manufacturing is discontinued.)

– TLT Radical ST Baltoro (orange plastic otherwise same as Radical ST.)

– TLT Speed (Classic introduced in early 1990s, see photo above)

– TLT Speed Radical (New version of Speed, another sweet spot in the line, no brakes.)

– TLT Speed Superlight (racing & lightweight tour, one adjustment for release values.)

– Low Tech Radical (combines lighter heel unit with TLT Radical toe)

– Beast 16 (Heavy duty “freeride” binding with additional elasticity.)

– Low Tech Race (same heel as Low Tech Radical, special race toe, very light at around 115 grams. Original versions lock into touring mode when you step in, later versions may not per new racing regulations.)
