Madone 6.5 WSD

[Mr. SR500]

You can flip the Bontrager stem either way (it's a beauty). But I would hold off on cutting your steerer until you have your fitting, until then you can simply stack spacers on top of the stem. I think you need to at least use one spacer (2.5 mm), but that with a 17 degree stem (may need a different stem) flipped down sill give you the most seat to bar drop. The top of the headtube on the new Madones is 30 mm higher then previous models, unless you go with the "Pro", but I'm not sure if you can get a Pro in a WSD. A smaller frame can also give you some more drop, but you made need the taller seat post cap and a longer stem.

P.S. Why not get the fit on the Madone rather then your current bike?
