Roller Sear
The roller sear makes a big difference, I really loved it when I hjad mine installed. Having said that I am saving up for a blade frame at the mo, coz they are awesome.
If you want to know about Cockers, there is a Tech-trix video about them about, I think there is someone on this board who can get you a VCD copy (can't remember who though
)
Couldn't understand your last question mate, sorry, could you put it in English please
Dude cockers rule, when you learn to use her you will love her.
The electro frame is in the order of £300 depending on which one you get.
