Looking to buy your 44639 kit but the hidden nut looks like a washer as opposed to a knurled nut

I've purchased a bike with SRAM red and quark power meter. The bike came as mid compact and I'm wanting to make it compact (50/34). The new ring that came from the shop along with the bike has no nut in the hidden hole and the quark instructions show installation by crimping the chainring and nut in a vice. Is your kit what I need? Regards. Ian
Hi, You need our part number 44640, it has the press fit knurled bolts. Thanks 23/04/2019
