Use
SWIFT 40 A (aluminum) for
SWIFT 40 T (titanium) for
low weight, high sensitivity
high fatigue life, durability
Maximum usable rpm 2,200
Maximum speed 240 kph (150 mph)
fits rim size (usable range)

*
* A special flange configuration is required for a 13 inch wheel. Larger diameter rims can be used, providing
that overall clearance from brake calipers and suspension components is maintained.
