The hub is very light. It felt lighter than my old wheelset. I have been using the power tap for 3 weeks and it has helped a lot with pacing my efforts. I bought the wheelset used on ebay for about 300 . It is the PT SL 2.4 wired model. It is an older version but works well. It has helped me learn to conserve energy on longer hills. I think you would enjoy using it if you are interested. Cheers to you
