I have a hybrid bike and I am converting it to drop bars.
My problem is, as I am going to install STI's, I need to change brake system as well. I am using V brake types, how can I understand if I can install caliper brake or not?
1- V brake is mounted on holes on the frame, are caliper brakes' start-end distance(I mean the distance between those holes and the wheel touch point) same with V brakes'?
2- Or, since my bike's frame is wider than a normal road bike(and using wider tires), is the distance between the mount holes OK or too wide?
This is the random v brake image http://bicycletutor.com/images/bike/v-brake-400x280.jpg I am asking about the horizontal and vertical distances here.
This is the most detailed image of my bike I can find http://www.sedabisiklet.com/images/products/3/622015171123_200.jpg, sorry I couldn't find any photos from behind or front, so I can't show you more details.
edit: Found some better pictures of my bike. Please check them.
back http://i.imgur.com/Hj0ccPg.png seems there is a hole like you mentioned. Not designed for mudguard (middle one, rear holes are for mudguards) I think
front http://i.imgur.com/XccwDqP.png there is a small hole there, under the cable
