TT handlebars- arm rest keeps shearing off

Any experience or remedial advice?

I have Vision Trimax carbon SI handle bars on my TT bike. And for a second time the aluminium armrest plate which the armrest is fixed to has sheared off. Concerned as it happened recently going downhill over a bumpy bit of road at an Ironman event. Luckily I didn’t fall off, but worse still I lost about 5 minutes due to not being that aero! Fixing bolts are tightened to manufacture guidelines. Next time I could be a DNF. Any advice appreciated.

    I've had this happen too. A couple of strategies

    Firstly, check the bolts regularly and especially before a race. A loose bolt is more likely to shear

    Secondly, check your bike fit and setup. Very little weight should be on the bars (road bike) and pads (TT bike). Basically any weight through your hands or arms should be for control
