According to WickWërks Cross chaining is the condition where the chain is running across the drivetrain centerline — for example: From the Big Front chain ring to Biggest Rear cassette cogs, or from the Small Front chain ring to the Smallest Rear cassette cogs. The two different cross chaining circumstances are depicted in the diagram below. Shown in Top view, looking down on the chain, chainrings, and cassette. It is illustrated as a triple, although it can also be used for a double.
This is a sample for a 24 speed or 3 x 8 Mountain Bike (MTB).
Proper High Gear Combinations
Heavy in pedaling (low cadence) but bike move fast (normally flat road).
Proper Medium Gear Combinations
Slight lighter than high gear, but bike move slower (normally leisure ride).
Proper Low Gear Combinations
Light in pedaling (high cadence) but the bike moves slow (normally slope or uphill).
Cadence = Pedaling Speed. Pedaling speed is depending on your leg's strength.
Gear Combinations to Avoid
Avoid these gear combinations as this puts additional stress on you bike components.
Gear Combinations For Beginner Riders
Medium gear. Put the middle gear constantly to [2] and just shift the rear gear [4 5 6]. You will feel slightly heavier when you shift the gear from 4 to 5 or 5 to 6.
