Replacement tips now available for Black Diamond poles. I ordered a pair off eBay, about 8 bucks with shipping. Talked to the folks a Black Diamond and they recommended placing the end section in boiling water to facilitate removing old tip. Tried it, no luck. Then I tried hot cooking oil, success! Musta been over 350 degrees.
Using some old motorcycle tricks, put the pole section in freezer, new tips in boiling water, gave the end of the pole section a coupla whacks with rubber hammer and viola! Poles good as new and ready for another thru hike attempt.
Oh, yeah. The BD site list two tips, long and short. My poles, Trail, had tips that are the same length as the "long" tip. Seems that the short tip aren't available yet.
