Indexed gears demand precise cable rigidity to deliver crisp, clean up equipment shifting. An under- or around-tensioned gear cable will toss the shifting out. The distinction between best shifting and skipping can be as tiny as only one millimetre of cable so make compact adjustments of 1 / 4 convert to screws and barrel adjusters and take a look at the efficiency in the alter before you make additional improvements.
Pedal the crank forward and manually push the derailleur to the biggest cog. If this action triggers the chain to come off the cog you need to flip the “L” screw clockwise. To achieve this, hold the derailleur so the top rated jockey wheel is under the largest cog.
If the highest pulley moves much too significantly to align with the specified cog, then the gear cable has to be tightened.
It’s the smallest things which can foul up indexing so take a 2nd To make certain. You’re seeking barely enough rigidity to take the slack out. As you make the adjustment, look at to view which the higher jockey wheel isn’t becoming pulled inwards from beneath the smallest sprocket.
But an exceedingly Repeated explanation for gear misalignment is a bent hanger. A little knock for the rear mech (eg parking bikes at your cafe cease) is sufficient to bend the hanger and damage shifting accuracy.
Make use of the barrel adjuster or change the cable tension to do away with any noise or rubbing. Idea: If you take stress off and it remains to be rubbing the limit screw may have altering a little.
Limit screws are smaller adjustable screws discovered on both equally the entrance and rear derailleurs. They serve two critical capabilities:
Welcome, fellow bikeaholics! Currently, we embark on the quest to unravel the mysteries of equipment indexing and tame People unruly chains! Prepare to here don your mechanic hat and unleash your interior bike whisperer.
Changing your front bike gears affects the full indexing of the bike’s equipment setup if it’s not perfectly indexed While using the rear. Right alignment also eliminates chain rub, which could problems your derailleur and chain after a while.

A barrel adjuster is usually a mechanism which makes compact modifications on the cable rigidity by successfully escalating or lowering the duration of your equipment outer.
Entrance Derailleur Adjustment: Subsequent, center on the entrance derailleur. Shift the chain for the smallest chainring and the most important rear cog. Loosen the cable anchor bolt and make sure the derailleur is in its resting place.
