Thanks for the advice robert and frosty. My biggest issue is $$. It's not a fancy bike and mainly used for commuting and weekend rides with the odd long distance trip. Wanting to upgrade in a few months hopefully so not really wanting to spend a lot of money on it at the moment, but still want to maintain it in good condition. Given it's only got a trade in value of about $3k it comes down to how much I spend on it.
