I'm thinking ahead to my next bike, I want to build up a Surly Crosscheck frame and use it for commuting, light touring, maybe a little trail riding. (I don't want to buy a new complete build because I don't want bar-ends).
Then I saw these mofos: http://retroshift.com/ and now I am certain I want these on my bike. Unless you CX guys know that these are actually crap. But they look like they work very well, and it would be a distinctive, unique touch that would help my bike stand out from the crowd (which hopefully won't get it stolen!)
So apart from the question of does anybody have experience with retroshifters and are they as good as they claim, I am also not sure whether to go bare and put on 3x8 indexed shifters (which I would have to find), or just buy the full 3x9 version with retroshift's own shifters on. ($129 for a bare pair, or $189 with their indexed 3x9 shift levers). (Or buy a brand-new Crosscheck, swap out the levers for retrofits and move the bar-ends onto them)
I have this impression that for ultra durability, it is best to stick with 8sp, because with 9+ speed drivetrains, the chains get so narrow and weak that they break a lot more easily. Is this just a myth? I am not a powerful biker (I have never broken a chain before), is this even something I should worry about?
