To all of those that know.
I have just started going out on my bike again, (three kids and all does not give me a lot of time), I have a "specialized hardrock sport 05" which I would like to convert to disc, I have been reading on the web, and Im not sure if I have this correct. I need to get new wheels 'Disc Compatible' and obviously the brakes, but can I get something like the Avid BB7 (mechanical) then I would not have to change my brake levers, because they are combined to my gear shifters (shimano), will the avid brakes be compatible, and are they any good, or are the bb5's better. I would like to go to hydraulic, but it's too expensive. I just need better brakes when im out in the hills, (I live in mid wales and there are some great hills especially the one down the valley into llangynog 'part of the CB loop') but I would also like to stop. Is it a big job to change the brakes over, and I assume that I can transfer my 'gear' cogs from wheel to wheel. aaaaahhhh sooooo much, please advise
