    Had a Sputhe aluminum arm on my ’01; was part of a serious bike weight reduction program. Probably 10+ pounds to loose of unspring weight; add a composite rotor for more loss = better handling…rather spend money on this than metalflake paint or pimpy looking wheels…

    Add a composite rotor and loose a bunch of unsprung weight = better handling. I’d rather spend on this kind of stuff than metalflake paint or chrome vegetable slicer wheels…

    And dont forget the carbon fibre wheels Brocks sells as well if your looking to drop a few extra pounds from your bike…a killer product as well…
