I tend to be overcritical and customers report items to be in better shape than expected often. From best condition to worst condition, my grading scale is as follows. Mint / near mint+ / near mint / excellent+ / excellent / great / very good / average / fair.

Description
Description
Super light and cool mountain bike crank from the 1990's! These were made by Precision Tooling, which also made Grafton cranks for a period. They also look very similar to Grafton Speed Stix cranks, as well as Cook Bro's Dog Bone cranks and CQP cranks.
This is the second or later version of the Topline crank with the compact BCD, designated "Topline Micro D Mountain Crank". The arms are turned on a lathe from aluminum billet, and feature a "ball" shaped end with the pedal threads. The spider is threaded onto the ball end, and secured with a stainless steel pin. Quite unique!
Condition:
New Old Stock. It has been mounted, but never ridden. Practically perfect, with these two very small exceptions: Small ano mark inside the taper area, and a few tiny pinpoint marks on the edges from shop wear.
