NON-DRIVE DRIVE
3mm
148mm
The Ai rear hub is offset 3 mm to the drive side.
This both aligns the cassette with the Ai frame’s
55mm chainline, and aligns the rim/tire with
frame’s centerline for correct tire clearance.
Ai wheels have equal spoke angles and tension
on both sides (non-dished wheel) which
improves wheel stiffness, strength.
• The 3mm offset is for 148 X 12mm
spacing only!
• Other Ai equipped bike with 142mm or
135mm rear spacing use a 6mm offset.
NOTICE
USE ONLY 3mm “Ai” OFFSET REAR WHEELS.
Incorrect wheel offset can damage your frame.
Standard wheel assembled on this frame will result
in insufficient tire clearance leading to rubbing and
serious frame damage. This kind of damage is not
covered by the Cannondale Limited Warranty.
Building/Truing a Wheel
If you chose to build, or true the wheel, make
sure the 3 mm offset is present. Consult with your
Cannondale Dealer if you have any questions.
