Dynafit Back Adjustment Plate
Here's what other sites are saying:
The adjustment range for the racing bindings Low Tech Race, TLT Speed Superlite and Low Tech Radical can now be increased to max. 60 mm. With the front plate weighing only 18 g and the rear plate 36 g, Dynafit has developed the lightest adjustment plates. The bindings can be moved and adjusted quickly and easily on the plates. There is also the option of mounting the adjustment plates either only on the rear (full adjustment range of 30 mm) or at the front and rear (full adjustment range of 60 mm).
