Motion Pro Chain Alignment Tool
Well made, but didn't properly fit NC700x stepped sprocket.
Quite simple design and well made however, it did not fit my sprocket very well, making it almost impossible to use for alignment. My NC700x rear sprocket is stepped down in thickness just below the toothed area for the chain. The design of the alignment tool's "mounting points" and the tension screw (on the opposite side) just barely contacts at the stepdown transition, making it almost impossible to get it properly positioned, in order to align the sprocket. A better design required to fit my sprocket (and maybe others that are stepped down in thickness just below the toothed area) would be for the tool's inner "throat" to be about an additional 1/8"- 3/16" deeper placing both sides of the alignment tool to tension against the sprocket below the stepdown point. After 8 or 10 attempts to mount it, I barely got it to hold to confirm alignment. Bottom line, I had previously aligned the sprocket using a metal straight edge, prior to using the "Motion Pro" unit. Due to the problems getting it properly positioned, I would not trust the Motion Pro unit with this style of "stepped down" sprocket

Useless for my application
This tool is no more useful than eyeballing chain alignment. If the alignment rod was a foot longer, it might be useful. Also the tool is not deep enough to clamp onto most OEM sprockets that have a lip below the teeth. The tool clamps onto that lip and doesn't sit flush on the sprocket.

A must need
For what it does, you can't beat the price! If you change your own tires or maintain your own chain then you have to have this.

Works as advertised. Don't over-tighten the mounting bolt, it appears to be made of plastic. That's the only reason I gave this 4 stars and not 5.

Simple but effective, haven't found a Motion Pro tool I didn't like. Revzilla FTW again!

Great tool with ease of use
This tool is great, very easy to use. Just wish the rod was a little longer but it still does its job well.

Yes you do need this.
if you want to know for sure if you have aligned you chain properly by this too.. Also, the price is awsome in my opionion i paid about two and half times this much for one from the place i get my Smart Chain chain and Titanium II sprockets, Krause Racing. Check em out. LIfetime garuntee but pricey. Anyway if your chain isnt aligned properly you loose horsepower at the rear tire and fuel mileage, About 3-5%. That is a lot, how much have you spent to increase your power by just 5 %. Just get this and be done with it. Worth what i paid, a bargain at this price.
