I do a 20km return commute to work each day on my Specialized Sirrus Comp which is fitted with Alex AT400 rims 700x28.
I was told these were rated for a 100kg rider, when I started in February I was 114kg now I'm 106kg.
Since I started I found if I went over bumps or cracks in the concrete fast I'd break spokes so I chose a smoother path.
Lately I broke 2 spokes on smooth concrete, one straight after the other so I told the bike shop (this was about my 4th time in for broken spokes) and they said because the bike was about 2 years old that the Taiwanese spokes it came with were probly all due for replacing with some better quality European spokes they supply.
So I got them to change all the rear spokes. Today about 3 weeks later I broke a spoke on smooth concrete again, took it easy for the rest of the 4km left and when I got to work and had a look at the wheel the next spoke along broke while I was looking at it.
Is there something wrong here or is it because of my heft that they keep breaking, I asked for heavier guage spokes to be fitted but apparently you can't do that?
Does anyone know of a solution - it will probably be about 3 more months before I fall below 100kg.
