80 grams weight saving.
Weight should not be prioritized over functionality and durability. But saving weight without compromises? That's Super Leggero.
The Super Leggero Kit includes 4 bolts and 2 axles, made of 7075 Aluminium. Your Madonna is currently equipped with steel versions of the same hardware. The Super Leggero Kit has been tested and has no different restrictions compared to the steel version.
The Super Leggero Kit weighs 44 grams, saving 80 grams over the steel hardware.
Assembling your new hardware it is best to put some grease on the contact surfaces and a little bit of medium strength thread locker on the threads.
