soooo i recently replaced my axles and cones after my rear wheel failed. i bought an Olympia from treats 11 mm. it was going good for about three rides not very far and guess what? rear wheel failure. same wobbly draggy wheel. i haven't had a chance to look at it again but i have a feeling my cones and axle may be screwed again. so any ideas on why this is happening? are Olympia products questionable? better grease? better balls? better cones? better axle maybe? i got snowflakes on a Newport. can i switch it up with a 12 mm easily?
