Confirmed with the guys at TriRig that those Wolftooth brackets can break if two bottles are mounted out on it.
Weāve been mounting a single bottle to them and havenāt had an issue (the 2nd bottle is mounted directly to the saddle or to the bta riser). But, weāre going to heed that finding and move our pro athletes to our own BTS double saddle bracket and BTA brackets like the ones above from Speeco and TriRig, and the Evolve carbon bracket, going forward.
