Two premium carbon poles, two very different bets. The Black Diamond Alpine Carbon Cork has eight-plus years of documented real-world durability on r/hiking but is officially discontinued. The LEKI Makalu FX Carbon AS costs $20 more, folds for travel, and carries LEKI's lifetime warranty. Here's the call.
Here's the evidence behind that call. Every row below is a decision-relevant difference, not a spec dump.
Before you click, here's what we couldn't verify in our research.
Is the Black Diamond Alpine Carbon Cork actually discontinued?
Yes. Black Diamond's product page for this model returns a 404, and the cons noted in our research confirm it is discontinued with a successor model recommended. You may still find pairs through Amazon and third-party sellers, but future parts and manufacturer support are uncertain. If you want a new Black Diamond carbon pole with current warranty coverage, look at the successor model rather than this one.
Carbon fiber or aluminum: which should I buy if I fall a lot?
Aluminum. Reddit users on r/Ultralight note carbon is much stronger axially, but most real-world pole breaks come from lateral falls, where aluminum bends instead of snapping. A csinstant.coffee blog post documented carbon poles shattering after a season of hard use, triggering a switch back to aluminum. Heavy users and beginners should consider aluminum. Both the Alpine Carbon Cork and the Makalu FX are carbon.
What height should I set them at?
Adjust so your elbows form a 90-degree angle when the tips touch the ground. For uphill sections, shorten by 5 to 10 cm to keep your posture upright; for downhill, lengthen by 5 to 10 cm for better braking. REI's expert advice page covers the full range. LEKI also offers a free online pole-length advisor on their site. Note that fixed-length folded poles (like Z-poles in their non-adjustable form) lock you into one length, so the Makalu FX's adjustability is a real advantage if you swap height on the trail.
Are trekking poles worth it for easy to moderate hiking?
Yes, per a top-voted r/hiking thread. The benefits listed by experienced hikers go beyond technical terrain: balance assistance, weight transfer on ascents and descents, stability checks on uneven ground, support during rests, and meaningful joint relief on the knees and hips. Both poles in this comparison are overkill for casual flat-trail use; if that's your primary terrain, a cheaper aluminum pair will get the same biomechanical benefit without the carbon premium.
Telescoping vs foldable: which one is right for me?
Telescoping (the Alpine Carbon Cork's FlickLock design) lets you fine-tune length continuously and is better if you change terrain often or share poles across hikers of different heights. Foldable Z-poles (the Makalu FX's SpeedLock Plus design) collapse into shorter fixed sections via an internal cord and deploy faster, which iRunFar specifically recommends for trail runners doing run-hike transitions. If you fly with your poles or stash them on a pack often, foldable wins on packed size.
