obviously it's your money and you can buy whatever bars you like - but if vibration is the issue then I think the bars will make sod all difference. You would be better off looking at your tyre choice, together with the pressure you run them at. That will make the single biggest difference to ride quality...
Thanks for your input. Always good to hear different accounts and views. I'll give them a try and see. I have just been paid for a homer I did and decided to treat myslef to Carbon bars.
