Comments about Nashbar Dust Cover and Chainring Bolt Tool:
The tool they are now (2014) shipping out isn't the same as the one pictured. It now has two hex wrench holes.
The problem is the middle prong is the same length as the other two, making the tool practically worthless. It will not stay centered on the bolt because of this, and the two slots means is has even less grip than a flathead screwdriver. Spend the extra couple of bucks for the Park Tool. This one is completely and absolutely useless and good for nothing and stripped one of my bolts.
Was this a gift?:
Bottom Line No, I would not recommend this to a friend
