Yes they are great brakes. The 4 pot XT's are very well regarded. They have amazing stopping power and modulation. Their biggest drawback is by current standard they are fairly heavy compared to modern ultra light discs. About 100g heavier per wheel than say an XTR. The price is pretty outrageus. They might be new but I remember them retailing for around $99 to $119 per set when they were the current model. $275 for the set is way too damn much. For $150 I might consider it.
