I dunno about the gloves--I don't crash often, but I'm sure that instinct will make me put my hand down first. Actually, last time I laid my bike down I did that, and didn't have gloves (rode off edge of MUP, and didn't merge back on properly). Luckily, the pavement was wet, I was going maybe 10mph, and no damage. Anyhow, shouldn't a biking glove be designed for 1) to prevent road rash if you wipe out, and 2) shock and vibration from holding onto the handlebars? I'd suspect that gloves for weightlifting are designed for grip and to prevent callouses, for that super long 30minute workout... Not for a medium grip for a few hours at a time.

[Ironically, just got into this discussion with my wife. She used to throw shotput. So I'm looking for more ammo. ]
