Trimming Black Diamond climbing skins involves a precise process to ensure they fit your skis perfectly, maximize grip, and minimize drag. The key is to achieve a custom fit that leaves your ski edges exposed for optimal performance.
How to Trim Black Diamond Climbing Skins
Trimming Black Diamond climbing skins is a straightforward process that customizes their fit to your skis, ensuring maximum glide and grip while touring. The essential technique involves using the provided trim tool with consistent pressure along the ski's sidewall.
Why Proper Skin Trimming Matters
Properly trimmed skins are crucial for efficient backcountry travel. They allow your ski edges to engage the snow for turning and traversing, prevent snow from building up under the skin, and ensure the skin's plush covers the maximum base area for optimal grip on ascents.
Tools You'll Need
- Black Diamond Trim Tool: Typically included with your skins.
- Your Skis: The ones you intend to use the skins with.
- Black Diamond Climbing Skins: Untrimmed.
- Clean Workspace: A stable surface to work on.
- Marker (Optional): For marking the ski base if needed.
Step-by-Step Guide to Trimming Black Diamond Skins
Follow these steps carefully to achieve a perfect custom fit for your climbing skins:
-
Prepare Your Skis and Skins:
- Ensure your skis are clean and dry.
- Attach the skin's tip loop to the ski tip, making sure it's centered.
- Peel the backing paper (if applicable) and carefully lay the skin down the length of the ski base, keeping it as centered as possible.
- Secure the tail clip, adjusting the length so the skin is taut but not overly stretched. The skin should cover the entire base of the ski, extending to the metal edges.
-
Trim the First Side:
- With the skin firmly attached and centered on your ski, position the Black Diamond trim tool.
- Place the trim tool so its cutting blade is aligned to remove material from the skin while leaving a small portion of your ski's metal edge exposed (typically 1-2mm). The guide on the tool should run along the side of the ski.
- Apply good pressure towards the sidewall of the ski to keep the tool securely in place and ensure a clean, straight cut.
- Consistently pull down the length of the ski to trim. Start from the tip and smoothly pull the tool towards the tail, maintaining steady pressure and a consistent angle. Avoid stopping or jerky movements, as this can create an uneven cut.
-
Trim the Second Side:
- Once the first side is complete, flip the skin trim tool (or the ski, depending on your setup) and position it on the untrimmed side of the skin.
- Again, align the cutting blade to leave a consistent 1-2mm of exposed metal edge.
- Repeat this process on the other side, applying firm, consistent pressure towards the sidewall and pulling the tool smoothly from tip to tail.
-
Inspect and Finish:
- Remove the skins from your skis.
- Carefully inspect both trimmed edges. They should be parallel to each other and leave a consistent gap along the metal edges of your ski.
- If there are any small burrs or uneven spots, you can carefully trim them with the tool or sharp scissors, but aim for a clean initial cut.
- Re-attach the skins to your skis to double-check the fit.
Key Considerations for a Perfect Trim
- Leave Edges Exposed: Always ensure about 1-2mm of your metal ski edges are exposed on both sides. This is critical for turning, traversing hard snow, and preventing snow buildup between the skin and the ski.
- Consistency is Key: Maintain consistent pressure and a steady hand when pulling the trim tool. Any deviation can result in an uneven cut.
- Storage: Once trimmed, store your skins properly (plush-to-plush or with skin savers) to protect the glue and extend their life.
Troubleshooting Common Trimming Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| Uneven Cut | Inconsistent pressure on the trim tool; jerky movement. | Slow down, apply steady pressure against the sidewall, and pull smoothly. |
| Skin Overlaps Edge | Trim tool not positioned correctly, or not enough edge exposed. | Re-position the tool, ensuring 1-2mm of metal edge is visible. Re-trim carefully. |
| Too Much Edge Exposed | Trim tool positioned too far inward. | This cannot be undone. You may need new skins or accept less coverage. |
| Fraying Edges | Dull trim tool blade; cutting too slowly. | Ensure your trim tool blade is sharp. Pull with consistent speed. |
