Echo Sonar 4-wheel Freeskates are the ultimate urban weapon. The wheel setup is nimble, agile and puts the rider in immediate control. Created for city skating down narrow streets, these skates welcome longer distances too. The shell and cuff are made from high quality and durable PP with fibre, and offers a responsive feeling coupled with the Flush Mount on Y hardware. Four-wheel frames are mounted with one sided speed axels, and four-wheel frames are mounted with solid two-piece axels with 2mm up and down rockerable spacers that allows slalom and wizard movements if wanted.

Echo Flush Mount is a cutting-edge frame mounting system that seamlessly integrates the frame and shell into one, with no bolts or fittings visible. The frame wing system allows for exceptional power transfer in every stroke, alongside an almost impossible ride height as low as 1.5mm from the foot to the wheel. Flush frames are mounted directly into the shell and is mounted to the wide Y/I hardware which is sideways adjustable inside the shell. A true innovation in inline skating.

Each skate packed in cornstarch bag with tools and user guide. We recommend tightening bolts prior to use and maintain the skate checking bolts and nuts after each time used or at least on a weekly basis.
