I know these are any older model of Avid's lineup but I was wondering what level they were comparable to now? 3, 5, or 7? I know the older 2.0 levers look like the new 7 level levers with the view ports and speed-dial so does that mean 2.0 brakes are like the 7's? In particular rim wrangler pads? Just wondering, I found a couple for a good price. Thanks.
