OK, folks. Please do me a 5-minute favor.
Look over the "main" information posts (Predecessor, etc)
Find the typo's and anything incorrect, or what you think needs changing.
Copy and paste the thread into a PM, and either add correction at the bottom, or in underline.
I'll look at each PM, correct the post, and we'll see how close we can get.
The gist is the OEM information, and touch-up gouge.
I'd like to see any OEM numbers on gearing, as well. I know the GPX was 52/42. I know the "round" Shimano was 53/39. I've seen different versions of the BioPace, both in 600 and 105. It would be nice to somewhat clear that up. Also, rear cluster info would be welcome.
