I'm not a gram-wennie, so weight is not a factor, but I'm not seeing much here to address my questions. I guess I'll check out youtube to get the real deal on them.
There's a good CGN video comparing the two. Bottom line is both are similar in dry conditions and discs are better in wet.
Discs are also better for long, steep descents.
Lots of reasons cited by pros for not using including problems with wheel changes, potential injuries in pileups, added complications, and many consider discs just aren't necessary because rims work fine in race conditions.
