When disassembling the crankset for use with the the middle and smallest chainring
will not need to be used, so they must be removed from the crankset. The chainring threaded bushes will be too long,
because they are no longer securing two chainrings. For this reason there are five chainring spacers included in the
small parts bag (to be found in every package). These should be placed over the threaded bushes before reassembling
the crankset, so that the single chainring can be properly and tightly secured. (chainrig bolts: 5mm allen key, lightly
greased, tightening torque: 7Nm/61in.lbs.).
