It sucks to buy a new pole just because a part was knocked off by a passing tree. See below for some pole parts available from Dynafit.
Ultralight Pole Straps - The same Ultralight Pole straps found on the Carbonio pole. Please note these are sold with black webbing rather than the green webbing shown in the picture.
Butterfly 2.0 Baskets - The updated edition of the user-favorite Butterfly Basket. This version has a detachable "surface-area extender" that increases or decreases float and weight. The 2.0 is a versatile basket with a carbide-steel Nordic tip.
Broad Peak Baskets - Push-on baskets specific to the Dynafit Broad Peak poles.
