About 45 or 50 km into my ride this morning I broke another spoke. I know the roads are rough and there are corrugations in places but this is ridiculous. I seem to be breaking a spoke on the same wheel every 200 or 300 kms. All spokes have broken on the rear wheel drive side and they are breaking at the nipple where the spoke enters the rim. From what I can find out, it may be one of two things: either the tension of the spokes is not right, or hard and sudden pressure on the drive train (i.e. going up hill) is popping them. I don’t think it’s tension. When I have replaced the last two spokes I have checked the tension on all spokes on the wheel. I have even tried to listen to see if they were playing roughly the same note. The wheel now has a few thousand km on it. I wonder if the original spokes are just crap and now after a few thousand kms they are all beginning to suffer from metal fatigue. I was at the top of a stiff climb when noticed I had another broken spoke today, and I had accelerated and hit the drive train hard a couple of times on the climb. But I’m not Chris Hoy for heaven’s sake! Time for a new wheel perhaps.
