How do you tell if my bike is 10 or 11 speed?

Determining whether your bike is 10 or 11 speed can be done by examining the following:

Cassette Sprockets: The cassette, located at the rear hub, will have either 10 or 11 sprockets depending on its speed.

Shifter Levers: 10-speed shifters have two levers, while 11-speed shifters have three levers, one for each chainring.

Rear Derailleur: The rear derailleur needs to accommodate the number of sprockets on the cassette. A 10-speed derailleur will have a maximum capacity of 34 teeth, while an 11-speed derailleur can handle up to 36 teeth.

Chain: A 10-speed chain will have 10 inner links, while an 11-speed chain will have 11.

Additional Considerations:

  • Hub Spacing: 11-speed cassettes typically require a wider hub spacing of 135mm, compared to 130mm for 10-speed.
  • Compatibility: Ensure that your bike's components are compatible with the desired speed, as some older frames and wheels may not support 11-speed systems.
