about
You must use rear wheels that are compatible
with the Cannondale Asymmetric Integration
(Ai) 6mm offset. OEM wheels built to this
specification are identified with “Ai” logo, shown
at right.
6mm offset /
55mm Chainline
The Ai rear hub is offset 6mm 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. (See
also, Maximum Tire Width in SPECIFICATIONS).
Ai wheels have equal spoke angles and tension
on both sides (non-dished wheel) which
improves wheel stiffness, strength.
NOTICE
use onlY “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
