haven't seen anything else on this but would really be grateful for some advice as i am a bit of a novice .

ihave a giant anthem 2 (07) and have had it for about 20 months. Ive decided to upgrade as and when things go wrong.

My BB is really noisy and my pedalling is not smooth. I was on a trail recently and at one point it was went really stiff :D and then improved enough for me to get round but was still noisy.

anyway, any recommended upgrades? and what benefits will i get form upgrading versus replacing with similar?

thanks for reading
