Hi there. I need a bit of help. I have just brought a secondhand Genesis single speed for an absolute steal. The guy who sold it had knee troubles and only rode it for a couple of weeks. He has actually upgraded lots of stuff on the bike including the disc brakes. They are currently the new style XT discs. My question is this, I ride my brakes American stlye as oppossed to UK. Meaning my rear brake is on the right. All my bikes are set up this way. I want to swop the hoses over from its current Uk set up. Is it just a case of swapping the hoses carefully, making sure that I dont pull the lever at any point or do they need to be bled after the swap? I dont have a bleed kit for Shimano brakes so hoping it will me a simple swap?
