After more than a year of deliberation, 3 weeks ago I bought a set of Mad Fibers. So far, so good.
The reason I bought them over others are:
- very light weight for the rim depth (sub 1300g)
- they do have some aluminum in the rim to act as a heat sink for braking (as an engineer, I think this makes good sense)
- I had a very good experience with a set of Spinergies I rode/raced for more than 15 years with zero problems so the full carbon, cannot be trued design was a plus not a minus for me.
- bling factor - I liked the way they looked (decals not included)
- competitive price
- no rider weight limit speaks to their strength. I weight 180lbs, but do ride on some seriously crappy roads (I live in China)
- 4 year warrentee
The only downside I've noticed so far is that they are noisy compared to conventional wheels or even my old Spinergies. One solution was to make sure the valve stem nut was tight. If that is loose, they really a noisy when out of the saddle. Even with the valve stem tight, the have some "drumming" sounds which I actually don't mind. The sound a bit like my old J-Disc off my old time trial bike.
So far, I'm very happy with them.
