Shimano disc brake hose compatibility I have a bike with Shimano XT disc brakes, model BR M775, which have too short brake lines for my new stem. 
So I want to replace them with longer brake lines. But when I go shopping for brake hose, there are many different ones. Shimano LX, XT, XTR, Saint etc. 
I realize I have to get plain hose without banjo bolts, but can I use any of the Shimano ones?
And are there any 3rd party ones worth considering?
You need any BH59 hose with the right ends. The commonly seen current model kit would be BH59-JK-SS, comes in black or white and 1700mm or 2000mm.
