Step-by-step instructions to replace the TriFit binding on MSR Evo Ascent snowshoes. Learn the correct side, tools needed, and common pitfalls.
Quick answer
To replace the TriFit binding on your Evo Ascent snowshoes, you'll need the correct side-specific replacement binding and a flathead screwdriver. The process takes about 10 minutes and restores full functionality.
Why replace the TriFit binding yourself?
The TriFit binding is a critical connection between your boot and snowshoe. Over time, straps can wear or the heel riser mechanism can become stiff. Replacing just the binding rather than the whole snowshoe is cost-effective and extends the life of your gear.
The TriFit binding is designed specifically for the Evo Ascent frame. Using the correct side (left or right) ensures proper alignment and security. The replacement part is available for either side, so check your existing binding orientation before ordering.
Step-by-step replacement process
- 1. Identify the side and gather tools: Check the existing binding for a 'L' or 'R' marking near the heel cup. You'll need a flathead screwdriver and the new TriFit binding. If the old binding is missing, note the frame orientation: the binding's toe strap should point toward the front of the snowshoe. Double-check the side before ordering the replacement part.
- 2. Remove the old binding: Using the flathead screwdriver, pry out the two rivets that secure the binding to the frame. Work slowly to avoid damaging the frame. The rivets are located at the toe and heel of the binding plate. Once removed, lift the binding off the frame. If a rivet is stubborn, apply a drop of penetrating oil and wait a minute before prying again.
- 3. Align and install the new binding: Place the new TriFit binding on the frame, aligning the mounting holes with the frame's existing holes. Insert the two new rivets (included with the binding) and press them in firmly until they snap into place. Ensure the binding sits flat and does not rock. Check that the heel riser tab moves freely before tightening the rivets.
- 4. Test the binding: Clip your boot into the binding and confirm the toe strap cinches securely and the heel riser engages. Walk a few steps in the snowshoe to verify the binding does not shift or loosen. If everything feels solid, you're done. If the binding feels loose, remove it and check that the rivets are fully seated. Do not use the snowshoe until the binding is secure.
