Mercury finish info
The mirror finish on Mercury frames can reveal fingerprints, tiny scratches, marks, and nicks. During normal handling and skating the frame may get scratched. Wiping dust and debris off of the frame can also put micro-scratches in the finish. Brand new Mercury frames may have micro-scratches from handling during manufacturing. There is no warranty on the finish of this product.

The Endless Slalom Trinity Frame is engineered for slalom and freestyle skaters with Powerslide TRINITY boots size 41 and up who demand unmatched control and versatility beyond the cones. Rocker axles on the outer wheels of this patent-pending, multi-setup design let skaters easily switch between Balanced Rocker and Slalom Rocker configurations.
Every design choice was made with one goal: to elevate slalom performance. By solving the issues that limit other slalom and freestyle frames, we’ve created an optimized platform that gives skaters the confidence to push their skills further. The result is slalom control that feels more responsive, more agile, and more precise.
Features
- Wheel configuration: 2x 84 mm outer wheels + 2x 76 mm inner wheels
- For the best experience do NOT mix round and bullet wheel profiles. Matched sets of Endless or Street Invader wheels can be purchased in our store.
- Multiple setups:
- Slalom Rocker - outer axles rockered up
- Balanced Rocker - outer axles rockered down
- Optimized for next-level responsiveness, speed, acceleration, and precise control of movement
- Adapted from our Arc 5-wheel frame designs
- Higher performing alternative to 4x80 options
- Overall wheel-to-wheel length equivalent to 4x80
- Familiar pivot spacing yields agility equivalent to 4x76
- Enhanced wheeling trick stability due to larger 84 mm wheels
- Low ride height set by 76 mm wheels
- Recommended for all skill levels
- Recommended for boot sizes 44 (28.5 cm) and below
- Patent Pending

Slalom
LEARN MOREA multi-setup frame designed for skaters who venture beyond the cones. The 84-76-76-84 wheel configuration provides an experience equivalent to 4x80, but with enhanced performance. Rocker axles on the outer wheels provide two different experiences:
- Axles UP: Slalom
- Axles DOWN: Balanced Rocker
-
Slalom Pro 80•72
LEARN MOREA single setup frame for skaters who demand the ultimate slalom performance. The 80-72-72-80 wheel configuration provides an experience equivalent to 4x76, but with enhanced performance. These frames feature aluminum Ultra Axles for lowest weight. This frame is recommended for sizes 40 and below.

Slalom Pro 84•76
LEARN MOREA single setup frame for skaters who demand the ultimate slalom performance. The 84-76-76-84 wheel configuration provides an experience equivalent to 4x80, but with enhanced performance. These frames feature aluminum Ultra Axles for lowest weight. This frame is recommended for sizes 41 and above.

Better by design
Standard Slalom Rocker
If it ain't broke, don't fix it. All frames in the Slalom series feature an industry standard 2 mm rocker.
Familiar Wheelbase
The overall wheelbase is similar to traditional 4x76 and 4x80 freestyle frames–heel and toe wheels are in familiar locations, exactly where you expect them to be.
- Slalom Pro 80•72 = 4x76 equivalent
- Slalom / Slalom Pro (84•76) = 4x80 equivalent
Enhanced Turning Radius
Compared to traditional setups, we reduced the inner wheels by one diameter size, which decreases pivot spacing and enhances turning radius. This is the sweet spot that creates a turning radius tighter than traditional 4x80 and 4x76 frames without sacrificing stability. We found that reducing the pivot spacing more than this makes the rocker feel unfamiliar and the skate feel unstable.
Improved Wheeling Control
Traditional setups use four equally sized wheels. The Endless Slalom frames feature an increased outer wheel diameter, by one size. This choice increases the contact footprint for more toe and heel wheeling stability, while limiting the rotational inertia of the larger wheels so that they are easy to adapt to.
The ultra-rigid structure also assists with precise control. Less out-of-plane frame deflection means when you move the skate immediately reacts and doesn't lose momentum through the cones.
Optimized Ride Height
Mixed wheel setups can often make ride heights higher than necessary, especially when outer wheels in a mixed wheel setup are much larger than the inner wheels. Our choice of 84•76 and 80•72 hit the sweet spot and allow all four wheels to be optimally tucked up against the boot.
Multiple Setups You Actually Want
While some configurable slalom frames on the market allow the user to choose a rockered or flat setup, the feedback we received was that slalom skaters never skate flat. Our non-Pro frames give skaters a second setup they actually want: our acclaimed Balanced Rocker.
Evolved From Our Proven Arc and Ultra Platforms
Evolved from our design experience with Arc 5-wheel and Ultra Series frames.
Arc-inspired configuration optimizations keep the rocker feeling intuitive. During our Arc development we found that large pivot spacing steps makes the rocker feel discontinuous and twitchy (bordering on unstable).
The structural design of the Slalom frames is adapted directly from our Ultra series. Slalom/freestyle skating at the highest level demands an unyielding, ultra-stiff platform for instantaneous responsiveness, acceleration, and sustained momentum, especially when maneuvering on a single wheel. We believe this to be the most structurally rigid slalom frame ever created. Speed slalom skaters will especially love the performance boost.
