With my last KH T-bar bracket snapping–most likely as a result of my aerobar extension creating too much stress on it–I needed to find a way to add eliminate that stress, but without switching to another “single” support like a stoker stem, which is non-adjustable.
I wanted to retain the T-bar bracket, and have an auxiliary support for it, that makes it significantly stronger, easily supporting the longer T-bar w/aerobar extension. Have a look!
