The Endless Arc UFS Frame is a precision machined, multi-setup 5-wheel frame specifically designed for skaters seeking the highest level of performance for expressive flatland styles that rely heavily upon precise edge transitions and ninja-like swivel moves.  Through a meticulous development and testing process we have engineered a frame that we believe delivers an innovative level of 5-wheel performance for Seba CJ, CJ2, SX, and SX2 UFS boots.  An exceptionally rigid structural design brings new levels of responsiveness, speed, and acceleration that enhance the execution of moves and open up limitless skating expression...and most importantly, fun!

For the best skating performance and movement tempo, our 5-wheel frames should be chosen based on boot size as noted below.

So far I think this frame is super fun! I tried these on both my USD Sways and then the FR UFR and Arc feels right at home for me on the UFR skate! Now all I need to do is practice more . But the frames seem super high quality and I love the fact that I can play around with rockering options

Great ufs frame

I got the endless arc 165 mount for my adapt gto's in the past for wizard skating but when I decided to invest in an aggressive boot to learn aggressive on the side i felt like the endless arc would be a great choice frame to compliment my boot of choice, FR Skate UFR Street AP Intuition Aggressive . Combining aggressive skating and wizard skating I'm sure has been done but it's something I want to learn. The combination is light on my feet

Great design, awesome look

Perfect for flatland skating sessions during rainy days. I am really enjoying the multiple rocker configurations, especially the one that mimics an ice skate (more rocker at the front, less in the back). Eager to try out the 84mms at the front and back to give some added speed for cruising!

A lightweight finely balanced Wizarding enabler

Before this, I had four other Endless frames (three trinity 4x84,4x90, 4x90LR and one 165 4x84), and I used to imagine what it would be like to use all the 5 axle wheel receivers at the same time. That is, to be able to mount 5 wheels simultaneously, thereby using all the wheel mounting points. Once I tried the Arc, I understood why it isn't just a simple matter of moving things in a CAD file to fit 5 wheels. This is a well made, finely tuned, light-weight rocker-ed frame with the intention of (a) giving you that seamless agile rocker, (b) being forgiving in its stability especially on one foot tricks, and (c) making you go fast as you can on 5 wheels. And the Endless Arc succeeds in all of these goals in my opinion. Especially in being rigid, lightweight and low to the ground. I feel much more confident in my flat-land skating with these frames. But most of all, these frames are just really fun. Anyone who enjoys flatland wizard skating should try these at least once in their lives.
