Canopus Speed Star Bearing DW

I didn't buy this to increase the speed of my DW 5000 single pedal. I bought it because the Canopus angled crank bolt, in my opinion, is better than the stock DW one on the spring assembly. The stock crank bolt has the spring connect to the rocker hub at an angle, which I think could've contributed to my pedal wearing down faster than it usually would. So, I bought the speed star made for DW 5000s and I found that the stock spring on my pedal didn't work with the speed star bearing. The hooks on either end of the spring need to line up straight otherwise it will not work. I bought my 5000 back in 2006 or 2007 so maybe those models had a different spring and newer models use a different design. It was easy enough to get a replacement spring and I can tell you that the DW SM-020 factory part works. However, it would've been nice of Canopus to have written this information on the packaging or somewhere in the online product description. This is the reason why I've given this a total rating of four stars. They need to be more specific. I haven't had a chance to put it through the motions so the overall quality remains to be seen. So far it seems very solid and plays smoothly.
