Trouble shooting:*If your derailleur overshifts the chain when moving from small ring to the big ring, it means your "gap" is greater than 2mm when chain is on big chainring (see video). You may need to reduce the gap. Your front derailleur may also be too high compared to what is advised on the video. Last thing to check is if your cage is parallel to the big chainring face.*If your front derailleur is hesitating to shift from small to the big ring then two issues may be present. The "gap" may be too small (It has to be 2mm - see video) or your cage is not parallel to the big chainring face. HOW TO MOUNT 110/4 OVAL CHAINRING: First, you need to remove your crank from your bike. 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. All Absolute Black products are designed in UK and manufactured in Poland (EU) to the highest standards of quality.
