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.
