Once removed, unscrew the 4 bolts that hold two chainrings together with a T-30 torx key. Remove both original rings. Locate the new oval inner chainring with the triangular timing indicator positioned behind crank arm. The bolt holes on the small chainring are recessed – so the nut heads will sit flush with the surface of the chainring - these recesses should face you when mounting the bolts. Absolute Black outer chainrings have a specific recess to accommodate the rear edge of the crank arm - position the outer ring to line up that recess with the crank arm. If you are only switching the inner chainring to oval - use the original bolts that came with your crank. If you are switching to a pair of oval rings, you will need a set of regular ‘double’ chainring bolts. Tighten all four bolts with force of about 5-7Nm. Mount your crank back to the bike. You may also need to adjust the front derailleur upwards by 2-3mm.\u003c\/p\u003e \u003cp\u003e\u003ciframe src=\"https:\/\/player.vimeo.com\/video\/153122911?title=0\u0026amp;byline=0\u0026amp;portrait=0\" width=\"640\" height=\"360\" frameborder=\"0\" allow=\"autoplay; fullscreen\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e \u003cp\u003e\u003ciframe src=\"https:\/\/player.vimeo.com\/video\/153122911?title=0\u0026amp;byline=0\u0026amp;portrait=0\" width=\"640\" height=\"360\" frameborder=\"0\" allow=\"autoplay; fullscreen\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e \u003cp\u003e\u003cimg src=\"https:\/\/absoluteblack.cc\/images\/strony-ogolne\/absoluteblack_mounting_instruction_road_oval_chainring.webp\" width=\"640\" height=\"360\"\u003e\u003c\/p\u003e \u003cp\u003eAll Absolute Black products are designed in UK and manufactured in Poland (EU) to the highest standards of quality.\u003c\/p\u003e \u003cp\u003eCranks visible on the photos are not included to the purchased chainrings.\u003c\/p\u003e \u003cp\u003eThe World's finest oval (elliptical) road chainring.
