Ξέρει κανένας κάτι περισσότερο για το φρένο της Black Diamond; Παρατηρήστε πως είναι "σπαστό" (!!!)

Αντιγράφω από μήνυμα του Πάσπα:
Απο όσο βλέπω τις αρθρώσεις, το έκκεντρο δουλεύει όταν τραβάς την λαβή.nΔηλαδή το έκκεντρο συνδέεται άμεσα με την λαβή και κινείται αντίθετα από την λαβή.nΚάτω η λαβή, πάνω το έκκεντρο.

You lose about an inch when ascending due to the lever action of the handle, but that's nothing. The levering action only works if you're using the handle - attaching through the top hole (as some ppl do in pulley systems) and it behaves 'funkily'. BD's teeth are a little less aggressive than Petzl's, but they're still not as rope-friendly as the ones Kong used on their Bonaiti-B.nnΚαι από rl=http://storrick.cnchost.com/VerticalDevicesPage/Ascender/LeverCamPages/HT1LeverCam219.html:1sbircqt]εδώ:nnCommentsnnBlack diamond clearly copied some of the old Kong-Bonaiti ideas when they developed the nForce, and I'm not really sure why they chose to do so. Like the Kong-Bonaiti, the nForce operates on an entirely different set of principles than handled eccentric cam ascenders. The moving frame takes some time to get used to if you are accustomed to other handled ascenders. One disadvantage is that this ascender is more difficult to push up the rope, particularly if the rope is hanging against a wall with one's weight on it. This situation can often be avoided by proper pit rigging. This ascender gives a little more lost motion than normal handled eccentric cam ascenders. I see two main reasons for this. The first is the pivoting action of the handle. The other is that the sling attachment point is located farther from the main rope, so the ascender cants away from the vertical with each step.nnOn the other hand, the lever cam design is less sensitive to rope conditions than eccentric cam designs. In particular, the nForce can be expected to hold under some mud and ice conditions where the handled eccentric cam ascenders ascenders slip.nnThe workmanship on this ascender appears to be quite good, and the construction is solid. All frame edges are rounded. The sheet metal shell has the same potential bending problem as all other sheet metal shells discussed in this site, but at least the nForce used heavy 4 mm. for the frame and reinforced it well. The riveted joints are probably the weak point. The sling attachment holes could have the same safety problem described for the Clog Expedition ascenders.
