So I have a fairly old but somewhat well-equipped Ghost SE 9000 (I think, will have to look closer when I get home). Bought the frame and wheels off a friend a few years ago, put some Magura HS11 brakes on and it's been fine all in all.
Now I might want to switch to disc brakes just because. The wheels/hubs have center lock so for most discs I'll need adapters.
I can't make up my mind if I want Magura, SRAM or Shimano. Trying to stay somewhat cheap as well. The Magura MT5 looks nice with the 4 brake cylinders. But I also like the SRAM Guide T or Shimano BR-M6000/7000/8000.
Anyone have some input on this?
