These cranks have been sitting in the box for long enough.
Grafton Speed Sticks with 175mm crank arms, 110 BCD.
MTB cranks with some scratches that probably won't polish out but otherwise in good shape.
These unusual cranks were made for one year only in 1991 when they cost $200, although a different version was later marketed by the manufacturer Precision Tooling as Topline cranks. These first generation examples are machined from aerospace grade (ie super strong) 7075-T6 aluminium/zinc alloy. The drive side weighs 250g and the non-drive arm 190g. JIS square taper axle fitting. Comes with allen bolt fittings.
