Hi, i'm new to the wide range of aftermarket parts available to buy for a bike and recently got put back on the right tracks when i enquired about a derailleur.
So i now need advice on what to look for i.e what make is good and reliable and what different types and sizes are available. I havent got a massive budget (as low as poss really unless impossible) so i dont mind second hand if this is recommended. Also im not to bothered about the name/brand as long as it is a solid product.
Thanks for your time
