The 20 grams of spec weight that Plum added to the Race 145 binding also add 20 millimeters of fore/aft adjustability to the heel piece. Doing the math, that works out to 1 mm/g and an impressive total package named the Plum Race 165. Made with the same extra-strong combination of steel, Fortal® aluminum, and Ertacetal® high-strength plastic, the ~165 gram race binding is engineered to withstand the abuse of everyday touring. And by adding adjustability to the mix, your rig can also withstand a boot sole length change without requiring a new mount. Cleverly, adding the adjustment plate only slightly increases your ramp angle (+1.5mm heel height) as the heel pedestal is lowered to compensate. The adjustment plate also serves as a convenient boot rest when flat skinning, preventing a negative ramp angle when the heel unit is rotated 90 degrees.
- Simple wedge flips down to cover the heel pins and give you an extra riser option in addition to flat.
- Heel pieces slide forward and backward within a range of 20 millimeters, or approximately three full boot sizes.
- High strength steel fork in the heel adds durability to the lightweight combo of titanium, Fortal aluminum and Ertacetal plastic.
- Optional crampon attachment accepts most tech binding compatible ski crampons.
- Binding is designed to release both vertically and laterally, though like all tech bindings it is not DIN certified.

Questions & Reviews
The only difference in the 165 from the 145 is the integration of a 20mm adjustment track. The weight savings per foot are accurately portrayed in the model names.
In addition to allowing you to accommodate different boot sole lengths in the same setup, this also helps to fine tune the 4mm gap if you’re worried about mounting precision. Another benefit is that rotating the heel unit allows for a truly flat skinning position, as opposed to the slightly negative position with the 145 when the heel unit is rotating. However, all of these bindings are intended to be used primarily or even exclusively by skinning on top of the heel cover with the heel unit straight ahead.
The heel pedestal and housing are shortened to compensate partially for the height of the adjustment track. So the pins and heel cover end up about 2mm higher for skiing and skinning, which can be viewer either as a positive as a negative, but either way the difference is very small.
The mounting pattern is also wider and longer than for the 145, which could be a plus if you think the physics of that reduces the chance of a binding pull-out.
About halfway through my use of the 165, I adjusted it for a different boot sole length. For both settings, the heel unit’s hold down screws have stayed absolutely tight.
