Klein Mission Control Air-Headset Tool Set: MC1 / MC2 - Shop Only (Mostly NOS)
Rare tool set that's absolutely necessary if you want to work on any vintage Klein mountain bike with the MC1 or MC2 headset. Comes in the original roll up canvas carrier and black stuff sack.
The vast majority of this tool is new old stock. There are a few pieces that were used once...I think just the three pieces shown in the 3rd pic with light tool wear, and probably the one long pipe without it's plastic bag. The rest are still in the ziplock bags they came in from the factory.
