Looking for some advice here. I'm in the market for a new cassette and want an 11-26 (10 speed) and am currently looking at either a 1070 or the new Red Powerdome. From what I can gather the 1070 will last quite awhile, but haven't been able to find much on the durability of the new red cassette. So I'm here looking for info/ advice. The money difference is a lot, but if I can get a few seasons out of the cassette, then I'm not concerned with the money aspect ( I typically get around 3,500-4k miles a season) and the weight advantage is quite nice. Any info would be helpful. Thanks.
