Monkdawg workling over Gwin's brakes first thing this morning before practice started. Official word is that the prototype brakes Gwin's been using since last winter failed about a minute into his run--Shimano engineers are tearing into the brakes to determine what went wrong. These are prototypes, though, not production, so the guts have subtle differences compared to what everyone else is running. Gwin was offered the production brakes as soon as they became available, but favored the feel of the prototypes over the production versions; my guess is that he will be on production brakes in Norway for World Cup Finals.
