I emailed Specialized to ask why the E5 product pages, along with all info on their site about the Diverge, says 42mm tire clearance, but previews have said the E5 versions only go to 38mm.
Hello,
The Diverge E5 Comp does have a 700 x 38c clearance in the rear wheel, and a 700 x 42. front tire clearance.
Such a bummer.
