I just bought 2017 NS Liar frame from CRC to build my speed machine for BMX track and 4X. I finished installed everyhting, leaving brakes last. And the brake tab appeared faulty, not aligned with any IS adapter. I tried Shimano, Sram and Clark in 160mm and 180mm versions. I went to ForTheRiders local shop in Brisbane and they confirmed the frame is off. But seriously, how, how is this even possible??!! The brake tab is one piece, not individually welded 2 parts. It must be made in a tooling. HOW could NS get this wrong??? This Liar frame has been same since years ago. I am just now banging my head onto the wall. Can this be fixed and any options? Last photo is what I found online, same frame. They must had luck with correct brake tab.
