They both have amazing power but in my opinion the BB7 is so much more grabby. Its alot easier to set up as well and not much can go wrong. Unlike hydrolic brakes which need bleeding and spilling brake fluid every where. Its also cheaper!
Clean the disk as best as you possibly can; wipe it all clean with soapy water and then cook it for a while in the oven. For the pads put them over the hob for a bit so that the oil can burn off. Afterwards try and sand them a little as this will remove any surface oil that may be left on the pad. If none of this works then you will probably need new brake pads as the oil has seeped to far into them for cleaning. Hope I've helped
Thanks again for all of the advice guys but I've just got my new bike so no need for any more. I've gone and bought myself a Zhi Zm3, rides like a dream.
If I were you I just wouldn't go there unless you are quality at welding. If not you would make it all wrong, the geometry would be wrong and the frame would probably be as weak as hell! I say you just send Iolo an email and he'll just sort you out.
I've never ridden a Zoo python but have heard lots of good reviews. I have though ridden a Zhi Zm2 and I can say that it is awsome, it does everything so easy and would be an awsome bike to own. It is quite short though. Hope I've helped
Put the tool on the freewheel and add on to it some major leverage, that should do the trick. You probably won't want to here it but I couldn't get mine off at all no matter what I tried so it had to be angle grinded to pieces to remove it.
I'd never knock a fromt rim brake but I wouldn't have a grind on the front. It may give you power for stopping but for going down a hill you would wear down your pads so quick plus they would have a constant spueeking to them. Just put tar on or run a disk! But Koxx browns are awsome pads in my opinion.
Although the Try All tires wear fairly fast the grip that you get from them is just awsome! If you can't justify spending that much money on them though get the Maxxis.
