My confidence was shot to hell with the BB7, on that particular descent.
Wow, your
Strava link speaks volumes about BB7 confidence, because instead of your usual 1st out of XXXX on the descent, it is 61 out of 113. That is a result more akin to the Ritterview's unskilled captain/pusillanimous stoker combo than the Marco/Ruth corner carvers.
No braking = no speed. Only a fool descends fast without the confidence lent by a powerful brake to pluck you from calamity though the hurtling speed and vertiginous grade combine to make your team a juggernaut.
