No it doesn't I have that brake, I have standard Echo Urban forks with the same setup you have their and it is a 180mm disc. If that was a +40 adaptor you would need a 200mm disc.
I have a Dell Inspiron 1525, I bought 4GB of RAM and now its faster than my dad's desktop computer, its great, super fast and i think its a 17" screen.
I use mountain king 2.4 supersonic on the back, has had 1 snake bite in about 6 months, and a 400g speedking 2.1 supersonic on the front, has never snake bitten and sometimes im surprised it hasn't. How is that rear rim ?
