Grind you will get good performance in wet and dry and the brakes wil work and hold alot better also a dab of tar can help becasue it is sticky but not to much other wise you pads will stick to the rim when you pull it
Yes matey there very easy to bleed basicly open the top cap then the little nut on the caliper pull the lever half way fluid will start comin out the little nut. then wait till the resivwire (sp) is emtpy then tighten the little nut up then fill the resivwire back up with dot 4 or 5.1 oil and repeat for about 5 minutes then tighten al the brake up if it doesnt feel very good do it abit more mine feels perfect now i popped it lol. EDIT: if that dont make sense use this Bleed your hope!
rite I think your talking about the 2 types of spokes on tarty ? if you are im pretty sure there the same just different colour options, and im running red anodized nipples in my front wheel and there fine , havent rounded one yet
