Black Diamond have revamped their poles spares for their aluminium poles in attempt to simplify things - time will tell whether this is in fact any simpler!
The sections listed below should provide suitable replacements for nearly all recent-ish Black Diamond aluminium poles. If you bend or break a pole it's nearly always the lower section that goes; however both lower and middle sections can be replaced if need be.
You need to know whether your pole is a Lightweight model such as a Pursuit Pole (in which case the lower section will be 12mm diameter and the mid section 14mm diameter) or a Heavy Duty version such as the Expedition Pole (in which case the lower section will be 14mm diameter and the mid section 16mm diameter).
You also need to know whether your broken pole is a Short version (mostly bought by women) or a Long one (mostly bought by men). However, the 16mm Mid Section is now only supplied in the Long Length of 460mm - but will fit both Long and Short poles.
The Lower replacement section includes the Pole Collar, Trekking and Snow Baskets.
The Mid replacement section includes the Flicklock.
Neither section has height markings.
NB2 These pole sections will not fit really old BD poles (which can often be distinguished as they have a red plastic end to them). Unfortunately there are generally no spares left for these much older poles, but if you need a spare section for a really old pole please email us a photo of the pole and we will see what is available.
NB3 If it is just the tungsten tips that have worn out/broken off your well-used Expedition Poles, the cheapest repair option is to fit a pair of Black Diamond Flex Tips to the ends of the poles.
