A tip from a reader just came in with snaps of the 2009 Trek Madone. I have a 2008 Madone and love it - so what’s new on ‘09? Looks like the folks in Waterloo may have finally gone to a replaceable hanger. For the racing set - this is good news. There have been plenty of frames mangled from crashing on the right side just because the hanger got bent. To Trek’s credit thought I’ve bent my hanger on a couple of different frames and each time the integrated hanger was repareable (i.e. just bend it back straight).
Here’s my concern: Trek runs SRAM. SRAM is notoriously intolerant of mis-aligned hangers. Just being off a little tends to throw me all out of whack. I don’t think Shimano has this issue because their top pulley has float too it - at least that’s the best I could come up with. Anyway, in the case of a replaceable hanger, it’s been my experience that the hanger tends to have some play in it based on how tight the skewer is. Seems that getting it “just right” enough for my SRAM to be crisp may be a challenge. Time will tell!
