Because i'm a new guy. I want to take part in the forum, get to know some new people and have a conversation about the bits im not so familiar with. Isn't that what the New Members chat's all about ? There's loads of threads about disks or rim brakes?, which pads are best?, which bike should i buy? I'm sure if we did extensive enough searching then most of the posts here have been answered already but we're all just trying to find our feet with the forum, make a positive contribution and say hello to a community of people who like the same things that we do. Many thanks for all your answers
