The ‘Race’ series from Plum have long been on the featherweight side of Plum’s eclectic mix of ski touring bindings. But don’t let the name fool you. Not only are these bindings ideal for ski mountaineering races, but they’re also just a solid pair of ski touring bindings that come in at an incredibly low weight of 170 grams.
Plum R170 Build
The first thing to note on any Plum binding is, of course, that beautifully machined aluminum. Get this binding in hand and you’ll quickly see how detailed the machining process is.
This isn’t just all done for looks, either, by using as few parts as possible and, most importantly, shunning the use of plastic, Plum have managed to create some extremely simple yet durable bindings that are all built around this finely tuned aluminum construction.
This simplicity and reliability can certainly be seen on the R170. Taking a look at the heel, you’ve just got a single U-shaped pin system that offers a release value of 8 (ideal for skiers weighing between 70 and 90 kilograms).
Then, holding the binding to the ski is an adjustment plate that offers 25 mm of adjustment (that’s three boot sizes). This plate offers a wider screw location than its smaller brother, the R150. This wider screw pattern will go miles in giving the binding good screw retention, particularly when it comes to working with aggressive and heavier skiers.
