I commute on a Specialized Sirrus Sport. I had been breaking spokes on my real wheel and out of frustration bought a Chukker rim with a Shim 105 hub and had it triple laced.

I rode today and found that either my fitness level shot way up or this hub and wheel have made a real difference. I was 3 MPH average faster and heart rate was 10-15 bpm lower on average.

my other wheel and hub were ofm.

Makes me wonder if I should change the front.
