Endless 110 Frame Introducing the Endless 110 Frame. This frame is a precision-machined, multi-setup frame designed specifically for high-speed and agile cruising using 180 mm compatible freeride skates. Endless believes it is the highest-performance 4x110 urban frame on the market. If you are looking for the ultimate in urban cruising, or you are a skater with a very large boot size, then you will love this frame. NOTE: This frame requires a raised-heel boot with 180 mm mounting. It IS NOT compatible with UFS or Powerslide Trinity boots. Features Features Endless 110 Frame The 110 features: Multiple setups: 4 x 110, 3 x 125 Balanced Rocker for 4-wheel setup Enhanced Flat configuration for 3x125 setup Has a very subtle micro-rocker—feels like a worn-in flat setup Compatible with bullet profile wheels only Internally bridged for stiffness Recommended for Intermediate and Advanced skill levels with supportive boot Recommended for boot sizes 42 (270 mm foot length) and higher Mounting: 180 mm (*may not be compatible with all boots) The boot should have fully threaded 7-hole mounting plates for best centering Compatible boots: FR1, FR2 (2016 and newer), FR3, Seba Trix 2, Seba High Light (Carbon, V2), Seba iGoR, Flying Eagle F6/F7, Flying Eagle Drift, Micro Delta F (carbon cuff); 7-hole mounts; Rollerblade Twister Edge*; Rollerblade RB* Not recommended: FRW, FRX, FR2 (2015), Seba GT, Seba Trix (5-hole), Powerslide Hardcore Evo, Rollerblade Metroblade, Micro MT Plus, Micro Delta (plastic cuff); 5-hole mounts; UFS boots *165 mm mounting is possible using a round hole in the rear, but the frame will be rear-biased on skates that do not have 7-hole plates. The frame will NOT be perfectly centered with 165 mm mounting. However, this additional hole works well for Rollerblade Twister Edge and RB boots, which inherently have forward-biased mounting.
