Ok ive been working at this bike shop for about 2 weeks now and i spoke to a guy who works there about bleeding maguras. I told him i had mine bled with water and he laugh and sed thats impossable but get this he sed he could bleed my maguras with air and he would only charge me a £10er. How stupid can you get how can you bleed a magura with a substance which is compressable. Anybody eles herd of an air bleed? lol. Cheers.
