Tuning + Mounting
FAQs > Tuning + Mounting
The following are specified mounting instructions that any skilled ski technician will understand and be able to follow. All new DPS skis purchased come with a mounting card detailing the same instructions. If you ever have any mounting or tuning questions don’t hesitate to contact us. We’re here to help you.
Suggested Mounting Positions 2016/17, Understanding the Midsole Line
The DPS midsole line is designed to place the ball-of-foot at the center of a ski’s sidecut. The midsole line is a recommended starting place, not a one-size fits all rule.
- For the Unisex skis, the midsole line is 7.5cm behind the center of sidecut. This idealizes a 26-28mondo boot size.
- For the Ladies skis, the midsole line is 6.5cm behind the center of sidecut. This idealizes a 23-25mondo boot size.
- If a boot is notably larger than idealized, then moving the mount -1cm may be considered.
- If a boot is notably smaller than idealized, then moving the mount +1cm may be considered.
To verify a skier’s ball-of-foot location relative to midsole, use a Brannok Device to find the length of the foot and the location of the ball-of-foot. Measure the length of the foot in cm, find the center-point, and then measure the distance that he ball-of-foot leads the center-point. If a man’s ball-of-foot is 7cm ahead of the midsole, than a +.5cm mount from midsole is an appropriate starting point.
When to Deviate from Midsole
Various ski styles weight the foot in a range of ways. To accommodate, DPS recommends a range in mounting position. An athletic (ball-of-foot) stance versus a neutral (equal weighting toe to heel) stance reward different mounting positions. To determine the stance, have the skier jump in the air and land in their “ready” ski position. Note the heel relative to the ground, the location of the hands relative to the waist, and the knee relative to the toes and instep.
- If the hands are low, the knee is centered on the instep, and the heel is close to the ground, we consider this a neutral stance, and moving the mount forward should be considered.
- If the hand are high, the knee is over the toes, and the heel lifts a bit from the ground, then we would consider this an athletic stance, and the midsole line is your friend.
Additional information about the skier’s style may be taken from their boot preference. A stiff (120-130 flex) boot with max forward lean (17-22deg) will generally prefer a midsole mount. A more neutral cuff angle (12-16deg) and AT boot or softer alpine boot (95-120) will typically prefer a more forward mount (say starting at +1cm).
SPOON & LOTUS 138 These skis are specially designed to locate both the ROCKER and SIDECUT profile relative to the foot. Beyond small adjustments for foot-size, DPS recommends mounting the Lotus 138 at + 1.5 for the correct balance point on the ski. 84.5 cm from the tail of the ski. The SPOON should be mounted at boot midsole.
LOTUS 120 The Lotus 120 Spoon in PURE3 construction skis best mounted on the boot midsole line.
The Lotus 120 HYBRID and older Pure: Carbon+Nano models follow DPS’ standard mounting algorithm, ranging from midsole for traditional GS ski styles to +2cm for the most neutral skiers - and most skiers finding +1cm to be their happy medium.
WAILER 112 & 99; Yvette 112; Nina 99 (Pure3, Hybrid, Tour1 and HybridT2) The Paddletech skis in the Wailer class follow the standard DPS mounting algorithm for the longer lengths (190 and 184), ranging from Midsole for traditional GS styles to +2cm for truly neutral skiers. Most skiers find +1cm to be the happy medium. The mid-length skis (176cm/178cm) are rarely adjusted forward, and only +1cm. Shorter lengths (158/168) are rarely moved forward unless a very small skier (22-23 mondo), with a neutral stance is skiing a lighter duty boot (aka Dynafit TLT5).
CASSIAR SL & 85 Both skis in the Cassiar family are designed to be most rewarding on-piste for a skier with a technical ski background making angulated turns that drive the shovel. For this reason, DPS recommends all Cassiar skis to be mounted on the line.
Mounting Instructions for DPS Pure3, Tour1, and Foundation Construction Skis
- Adjust the binding installation jig to the boot and lock in position per the binding manufacturer’s instructions. Appropriately sized binding installation jigs must be used to insure proper centering of the binding.
- DPS skis are generally mounted at a mid-sole position. Position the mounting jig so the boot mid-sole is aligned with the “MID SOLE” mark on the ski. +/- 1 cm off mid-sole is perfectly acceptable to fine tune to your style and expectations. Contact DPS for further recommendations on mounting position, if needed.
- Use a 4.1 mm +/- 1 mm drill bit extending no more than 9 mm beyond the collar. Please note: the 168 W112RP Pure3 and Tour1 may require a shorter drill bit and screws for a junior binding mount.
- Countersink the hole but do not remove more than 0.5mm of material in width or depth. Alternately scrape or file off turned up topsheet material.
- It is imperative to seal the screw in the hole and bond it to the topskin and core to make a single bonded system. Fill the holes with a two-part liquid (not paste) epoxy or one-part polyurethane before installing the screws. Failure to do so may void the warranty. Devcon, 3M, Hardman, Gorilla Glue, and Hysol make excellent two-part epoxies for the task. Gorilla Glue, Titebond Polyurethane, and Elmer’s Polyurethane are excellent one component adhesives.
- Make sure the ski is at least 13 mm thick where a standard binding mounting screw is installed. If the ski is less than 13 mm thick, shorten the screw by the difference between the ski thickness and 13 mm.
- Measure to make sure the screw does not project more than 8.5 mm below the binding.
- Drilling extra holes or re-mounting a binding can void the warranty for related damage because holes are too close together. Extra holes must be at least 1 cm apart, preferably 2 cm apart, as measured down the length of the ski. Drilling extra holes less than 2 cm apart can dramatically reduce the strength and durability of the ski.
Base Edge and Side Edge Tuning
The flex profile tuning of all DPS skis negates any need to dull or detune the ends of the ski. Adjust only as needed, after slope testing, to address any negative performance related issues that can be associated with a sharp tip or tail. Because of the high torsional stiffness and relentless edge hold of a DPS Pure: Carbon + Nano ski the main edge tuning issue is removal of burrs on the edges from tuning, handling, or slope damage. Wax is good. Use it as often as possible to maximize the performance and fun of skiing.
Powder skis inherently are used in potentially adverse terrain and rocky areas in pursuit of powder. Do not expect any warranty consideration for damage as a result of hitting debris or rocks. While we make our best effort to make them damage tolerant, these skis are made for use on a snow surface only. On the other hand, what might appear as substantial damage can actually quite easily be repaired. Epoxy can be used to fill the cracks, delams, or splits. Normal ski repair procedures apply to both DPS constructions (Pure: Carbon + Nano & HYBRID, Hybrid T2, Tour1 and Foundation)
- 1.5 BASE EDGE (Lotus)
- 1 BASE EDGE (Wailer and Cassiar)
- 2 DEGREE SIDE EDGE
- CERAMIC FINISH
- BROKEN LINEAR STONE PATTERN
- ROTOBRUSH PRIOR TO USE
- ADD BASE EDGE BEVEL OR DETUNE
- CHECK BASE FOR FLAT
- CHECK BASE EDGE BEVEL
- CHECK FOR HANGING SIDE EDGE BURR
- ADJUST BASE PATTERN AND WAX FOR SEASON
