Product Description

One of the quickest, easiest ways to destroy a set of chainring nuts is to try jamming a flathead in the slot to hold them in place. Do yourself a huge favor and pick up the Park Tool CNW-2C Chainring Nut Wrench. You'll be glad you did when you get your rings off without a hacksaw and a shredded crankarm spider.

Strengths:    Strong, corrosion-resistant, lasts forever.

Weaknesses:    Thin edge hurts the hand. Tool slips on occasion.

Bottom Line:   
Hey, it does what it does and as well as anything else. The technology -- a bolt that goes into a slotted nut -- is pretty old-school (and not in a good way). The tool tends to slip, at least until the bolt is tight enough so that it stops slipping. And the flat metal of the tool cuts into your palm a bit when tightening.

Newer bolts -- with different-sized hex key slots in each side -- may be the way of the future. I've already seen this used on a SRAM crankset. For now, though, this is generally the technology we have.

My suggestion: Go to a sporting-goods store and get a roll of the cloth tape used for baseball bats and weights. Wrap that a few times around the middle of the tool. More grip, more comfort, better tool. That's what I do.

Strengths:    It's plated so it won'y rust. Low Price

Weaknesses:    Low price = Low quaity and precision tool

Bottom Line:   
This tool is useless. I tried it and it kept on slipping out of the slots. It has so much play. The width of the slot is much wider than the actual tool thickness. There should be a snug fit to prevent busted knuckles. I finally was able to tighten things up. I would not recommend this to anyone. It is a piece of junk. The bike shop claims they use the same. I highly doubt it. You would be better off with a really wide screwdriver.

Strengths:    Simple and effective

Weaknesses:    Handle is a bit too short. More length would make it easier to use.

Bottom Line:   
Holds the nut fairly well, much better than a coin or screwdriver. The handle is a bit short but it does the job fairly well. Buy it if you plan to tweak your gearing or if you like to strip everything down for overhauls. Don't bother if you never fool around with your chainrings
