Ive got some,and they are strong in my opinion, im 15 stone and havnt noticed any flex, i fell off a mountain and my bike landed on the bars and saddle, upside down, smashing my lovely garmin to bits and the very very ridiculously priced reverb switch, leaving fair size scuffs scratches and dinks in my bars, i rode the rest of the day with no problems or worries. This is the good bit, i fell 25foot off the mountain to rocks and just got up with a few scratches and a swollen but not sore wrist, i am a lucky git, i was in chamonix, charlanon trail les praz, it was the the 11th of sept, at 10.25 am, as i landed, a massive part of Les Drus came tumblin down, filling the valley with dust, we joked about the butterfly effect. Sos about wafflin on but its a good story (in my head). I have since replaced the bars with new Havens.
