Looks really similar to a home-brew rivnut tool.

Hub spoke hole slotter for aero spokes.

Jon is correct. It is used to slot hubs for aero spokes.

Markus - 05/20/13 - 9:43am

A tool to hold a freewheel so you can rebuild it?

Damn Fatboy, you beat me to it, though I was going to add proto w/ Mono-link seat attachment.

Chainwatcher for direct mount front derailleur.

It’s hard to judge scale etc but it looks like the arm minus the spring from one of the after-market derraileur tensioners. Hole in bar allows you to trap the arm between hub and dropout, spring attaches to rear of the mech cage to add tension.

Answer from Nick at Crumpton Cycles: It is a tool from the late ’80′s/early ’90′s for slotting the spoke holes in hubs to accept the fat blades aero spokes of the day. Basically a drill guide to be used with 1/16th” drill bits and a hand drill.

campy seatpost measurement tool, obviously.
