If they made pink M&M's, they'd be the best too!

The 543

The 543 got the name from its specs. It’s 54mm wide, 54mm in diameter and weighs in at only 63g. It comes standard with a gold NSK bearing and takes standard 19mm pads. It’s an extreme design made from 7068 aluminium. Each 543 is engraved with its own number from 0 to 30 as only 33 were (and will ever be) made. 31 of them are engraved and the remaining 2 are unengraved and owned by me. Each 543 comes in a magnetic box with a certificate of authenticity, some stickers, and an Airetic string.
