I'm not sure how many of you bother with wheel balancing but I've always tried to keep them in the ball park. I use solder wrapped around the rim end of a spoke to get the wheel as close to balanced as I can. A day or so ago I was checking my speedo sensor and had the front wheel off the floor and found it very, very heavy at a point well away from my solder wrap. I went through the process again, got the wheel back in balance but after setting for a few minutes I discovered another heavy spot where the wheel sat against the floor. Then it dawned on me. "Duh", the 'SLIME' is running to the low area when the bike is standing still. That makes my efforts to balance useless. Just wondering if anyone else has found that adding 'SLIME' to their tubes has effected the way the bike rides. I have not noticed any discernable difference so maybe it's a moot point. I typically ride in the 15 to 18 MPH range so maybe at those low speeds I wouldn't notice but I've occasionally riden for some distance at 25+ and still felt no undue wheel vibration or hop. Does the 'SLIME' distribute evenly when the wheel is spinning?
