[C] Use the uninstalled enviolo hub interface to determine the desired orientation. Typical orientation is forward, parallel to the chain stay or seat stay cable routing. Move the enviolo hub interface along the dropout to ensure clearance at different axle positions. For the variant SP the orientation is not important.

• [D] With the interface oriented correctly inside the right dropout, the installation angle is the indicated
angle of the dropout (20 degrees in this example).

• [D] Use the markings on the hub interface to determine your approximate installation angle.

• [F] Remove the anti-shift retainer, if installed and ensure that markings between the spline nut and the shift driver are aligned.

• [H] Prior to installation, set the hub interface to the full overdrive position.

• Suspend the hub interface over the right hand axle, and align the axle flats with the installation angle.
• Alternatively, a non-turn washer can be installed over the interface to align the installation angle.
• When the installation angle is aligned, ensure the hub interface is set to full overdrive and seat the hub interface fully onto the shift driver and the spline nut until it is flush with the spline nut, as shown.
• Thread the right hand nut, serrations facing outward, onto the axle and tighten to 10-15 Nm (7-11 ft-lbs). Install the rear wheel.
• [I] For the variant enviolo SP 135 mm:
Thread the adapter shafts into the hub and tighten to 10-15Nm.
• [J] For the variants enviolo SP 142/148 mm:
Place the spacer on the hub and thread the LNUT onto the axle and tighten to 5-10 Nm
