The Ai rear hub is oset 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 stiness, strength.
• The 3mm oset is for 148 X 12mm spacing only!
• Other Ai equipped bike with 142mm or 135mm rear
spacing use a 6mm oset.
NOTICE
USE ONLY 3mm “Ai” OFFSET REAR WHEELS. Incorrect wheel
oset can damage your frame.
Standard wheel assembled on this frame will result in
insucient 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
