Looking for more advice please, currently Iam running on a cheap Bontrager chainset and i get alot of flex from it. Iam 15 stone so this won't help, so Iam thinking of putting the new Dura Ace on it, would this make a big difference.
I went from a 105 octalink chainset to a Dura ace 7800 (octalink 2) chainset and as soon as i set off i noticed the difference. Well recommended upgrade.
