Vintage Kooka I-Beam Crankset: Silver 94/58mm, 175mm, 42T Near Mint

Kooka (short for the Australian bird, Kookaburra) is known for their short run of high quality, high bling factor mountain bike parts in the 1990's anodized era.  This is a versatile version with silver arms on silver spider.  Comes with a period correct Suntour XC chainring in 42t.  It's set up as single speed with SS chainring bolts, but this crank is designed to be a triple.  Just add a couple more chainrings and switch the chainring bolts.

This model is also referred to as the I-beam crank.  This the 2nd or 3rd generation crank, which has fixed the non-drive arm cracking issue the 1st gen cranks had.  Kooka added 2mm of material around the taper on the non-drive arm to add strength.  They also have the milled arm ends (which lighten the arms and keep them from looking bad when they scrape) that the 1st gens did not have.

Condition: 

Near mint lightly used shape!  At first glance you could almost mistake them for NOS.  There are some quite light cosmetic marks, primarily light heel rub on the non-drive arm and some scratches on the arm ends.  Chainring is in excellent shape.  The chainring bolts look great, and the spider is nearly perfect.  Tapers and threads in great shape.
