This review applies to the mounting of this hanger to a 2009 Issac Efficiency TT carbon frame (the yellow one): Delivery to Germany was fast and the service staff answers quick-ish too. Positiv was definitely that, altough service said the package would'nt include screws, it came with two recessed m3x8 screws, with a 6mm thread. Sadly they were to short by 1 mm, not a big problem. I cut two m3x10 screws to the correct size (7mm of thread is perfect). A small negativ aspect is the tolerence on the hanger itself: The fit is really tight, too tight. i had to ever so sligthly grind down a couple parts of the hanger, especially since the corners were kinda sloped. Now it fits like a glove... :)
