Hi,

I need assistance in identifying break types for the purpose of break replacement. 5 images attached for 2 bikes: 3 for mountain & 2 for road (sorry for bad quality & dirt). Mountain bike has V-breaks.
1. Are the road bike beaks v-breaks as well (They seems so)?
2. Are the mountain & road breaks "threaded"? How does one tell? should I dismantle to determine?
3. I'm considering the kool-stop thinline if appropriate but the road bike has more clearance. any other suggestions?

Thanks
