-
BB30 frames should have a inner diameter of 42mm
-
The BB30 BB is the same for XCX, TRS and LG1 cranks as well as all legacy models
-
BB30 BBs work with 68mm and 73mm wide BB shells
-
Start by measuring your BB shell and choosing the correct number of spacers to use between the BB and the frame using the chart
-
-
-
Grease the center threads of the BB
-
Refer to and follow your frame manufacturers specifications regarding the use of grease on the inside of the BB shell.
-
In general we recommend grease, but some carbon frames may not be compatible with it.
-
Thread the BB together making sure that the cups and any needed spacers are centered before tightening
-
-
-
Using an e*thirteen BB tool, a 10mm hex bit and a torque wrench, tighten the BB to 34nm
-
-
-
Using the chart, determine the number of spindle spacers needed for your BB shell width and spindle
-
DH cranks such as the LG1 use a bit longer spindle than XC cranks so be sure to use the proper number of spacers
-
-
-
Lightly grease the crank spindle and install the appropriate spacers on the drive and non-drive side of the spindle
-
In this case we are installing LG1 cranks so spindle spacers are needed
-
-
-
Depending on the model of cranks to be installed:
-
Install the cranks using the wave washer and spindle spacer preload system
-
-
As always, be sure to properly torque the cranks to spec using a torque wrench
