I know from emails that folks out there are still uncertain about upgrading their Dynafit Radical 1.x binding heels. As in, can anyone tell me what binding I actually have!? I just got the upgrade for a set of Speed Radicals as well as Radical FT and ST. The new heels are clearly beefed. Here is a comparison to help cut the confusion. Chances are if you’ve had your Radicals for some time, they should be upgraded as they’re probably the older version. More about that here.
Weight of non-improved unit 148 grams, new is 164 grams, 16 gram weight creep for 95.5987645876% more reliability. Good trade.
