Index Systems and the exchange of different systems.

Index Systems and the exchange of different systems.

For the proper functioning of the index system, it must meet the following conditions:

  • The sprockets must always bear the same code.
  • The sprockets must be fitted with appropriate spacers.
  • The chain must fit the sprockets and chainrings used.
  • Switch and derailleur must match the distance between the sprockets and chainrings.
  • The freehub should fit the sprockets used.
  • It should be used a rigid outer casing and within pre-stretched cable.

The distance between the chain wheels at a 7,8 or 9speed group are different. At Campagnolo is the distance between the sprockets, at an 8-speed 3.2 mm. At 9-speed, this 2.8 mm. In a 9-speed system should then also be fitted a super narrow chain. The chains of 8 and 9-speed system therefore can not be exchanged.

The chain of a 7-speed system can not be used with an 8-speed system. An 8-speed system namely has a narrower chain.

The SRAM ESP systems are not compatible with other systems. The reason for this is the difference in transmission ratio. The other systems of SRAMSachs ARE compatible with Shimano systems: a grip shift rotary switch can be combined with a Shimano derailleur. The number of switch gears must of course correspond.

For Campagnolo all groups can work together.

Parts manufacturers provide different groups whose components are often interchangeable. The rear derailleur and switch are interchangeable when :

  • The number of sprockets which the switch and rear derailleurs are designed is equal
  • The distance between the center lines of the chain wheels is equal.

Although it is advisable to mount the special chain that corresponds to the indexed switching system, it can not hurt mounting a different chain as long as it fits between the chain wheels. Manufacturers of spare parts specify the group that component is and is not appropriate. To conclude this section are some exchange tables for manufacturers.
