When braking (with any kind of brakes) the tire is subjected to friction against the road. If by mistake a clincher tire has grease all around the two bead sides, it could potentially spin while the rim has locked. Is that right?
We anyway never add any grease to rim, rim strip, inner tube, or tire, but should we ensure that no spinning will occur by adding a hint of glue anywhere? Are the bead friction and a properly inflated inner tube sufficient to avoid slippage?
Mainly I'd like to know (that's my "one question" here; feel free to ignore the many side questions):
Should the rim strip be glued to the rim? I expected rim strips to be sold with paper that gets pealed to reveal self adhesive on one side against the bare rim, but they are fitted to the wheel (rim tape: 700C x 18mm), and without any gluing only the tension will keep them in place. Even though we are not talking here about tubular rims, how do we avoid that the valve loses orthogonality to the rim after many rounds of braking—short of gluing? It would be nice if all rim strips have a self adhesive, no?
I'm also curious about the logic behind the conventional wisdom of adding talc powder to the inner tube to ensure it doesn't stick.
Could talc powder make the tire spin during (hard) braking if an excess of talc powder makes the tire beads slippery against the rim?
