Derailleur Hanger replacement for GTS R5 road bike frame I'm looking for an online site where I can buy a derailleur hanger replacement for my GTS R5 road frame.
The frame is the one in the picture (http://4.bp.blogspot.com/_0EL4iQdWrYE/TDLCN-kYeQI/AAAAAAAAAQI/JmNVEhIR5n0/s320/gts+r5.JPG)

I bought a derailer hanger (dropout 6) from amazon 

http://www.amazon.com/Wheels-Manufacturing-Dropout-6-Derailleur-Hanger/dp/B0028N1SDA 

but it's not the correct size/form.

I google for "GTS R5" and some other alternatives but I can't find a reliable place where they sell this Derailleur Hanger replacements.

Any help would be appreciated.
My local bike shop and I'm sure most others have a large "deraileur hanger" wall chart from Wheels Manufacturing or other supplier. The 170 plus pictures are life sized. All that is required is a visual match. Wheels Manufacturing has a database on their website but doesn't list a GTS R5. I would either visit your local shop or contact Wheels Mfg.com customer service dept.
