I will ask my fellow mechanics about rear derailleur set up. I know there is a fine line with the rear loop on the length and precise shifting. If it is too tight it generally will cause more problems than too big a loop. I not sure if the loop should go all the way around the quick release but my set up seems to have the line of the loop going right over the QR. I personally think the biggest rear loop you can get that is smooth is the best, do any of you subscribe to this?


The reason I ask is I am very OCD about shifting and hate to miss any shifts period. I find the going to the bigger cogs in the rear never a problem but if I get it too tight then it does not always upshift perfect. Turn the cable adjuster just a 1/4 turn will usually get it perfect.


Finally, on my Wilier I am running 10 spd Ultegra and about a year ago upgrade and got the Shimano Polymer Coated cables and housing. I put those on and in the 4000 miles since then they have shifter perfect never a missed shift. I wonder if maybe going to these exclusively is the way to go. This has the cables buried in the tubes and is much more susceptible to problems and the new shimano polymer stuff has taken care of that issue.


How do you run your rear derailleur loops?
