Kevin M. Mai ZhongJie helped me acquire these #672 left and right ascenders from I Climb in 2023.
The I Climb (元鴻興有限公司) #672 ascender comes in both left-hand and right-hand versions. Each ascender is 110 mm. tall, 60 mm. wide, 36 mm. thick, and weighs 128 g.
The ascender shell is hot-forged from 6061 aluminum alloy and then soft anodized. It is 4.4 mm. thick with some thinner portions in less critical areas. The rope channel is 17 mm. wide. The cam axle is centered 46 mm. from the inside of the rope channel. There is no cam stop. The attachment points are holes in tabs on the top and bottom of the ascender. The tabs are dog-legged inwards, accounting for the ascender's rather large thickness. The top hole is circular with a 17 mm. diameter. The lower hole is shaped like a rotated "D. It is 19.3 mm. tall and 22.4 mm. wide.
The cam is a steel steel casting of the drooped type. The cam radius, measured from the axle axis, increases from 33 to 53 mm. over an angle of 38°, giving a 36° cam angle. The cam has number of small conical teeth, all of which have their axes approximately perpendicular to the cam face. The tooth pattern is ((2)(1H1)(2.3))^3(1). A spring-loaded manual safety is mounted on an axle riveted to the center of the cam. The normal action of the spring holds the safety against the cam.When the cam is opened, the shell interferes with the safety, thus preventing cam opening. At full open the safety can be released and the spring will hold the tab behind a pin riveted to the shell, holding the cam open.
The front of the rope channel has a raised forged up-pointing arrow with "UP" beneath. The front is printed with "iclimb®" and "Made in Taiwan." The rear is printed with "iclimb®," "Made in Taiwan." "CHEST ASCENDER," "EN567," "EN12841," "MAX 150 kg," "ROPE: Ø10-13 mm," and "CE."
This is a small, light, and solidly-made ascender. Its small size makes it rather difficult for me to operate, especially if I'm wearing gloves. I don't normally climb Frog and I would not make this my normal chest ascender, but folks who place a premium on weight might find it attractive.
The cam safety is easy to operate, even with one finger (albeit not a finger inside a thick glove). Opening is a simple downward motion, but locking requires a distinct upward motion at the end, giving a combined two-step motion that is worth practicing. Releasing a locked-open cam is also a simple, one-finger operation.
As with any ascender cam with cam-face mud relief holes, the holes work best on mud that is far less obnoxious than what I'm used to seeing in our caves.
