The left hand steel blade spokes of my WH-RS30 (not 30A) are constantly exploding inside of the nipples when going up hill in a standing position. I have increased the right hand side tension to about 2150N (1600N is the recommended limit for the rims) and the left hand side to about 1150N (1100N recommended limit). The wheel now however is not perfectly centered, but slightly shifted towards the left. Is that acceptable?
I don't want to tighten the right side any further, but lower tension on the left is not acceptable either. I only increased the tension by about a 1/4 turn.
Is going that much above rim recommendations dangerous? No right hand spoke ever exploded, only the left hand side. Might I just be to heavy / "strong" with 90kg?
Maybe my TM-1 (tensiometer) is a bit off? The left side spokes still feel awfully easy turnable. What settings do you use on your TM-1. Mine are 20 right - 15 left because I think the spoke is closed to a steel blade with 1.0mm x 2.2mm
Interestingly, as I ordered repair spokes, they came with longer nipples (part number didn't change). Is this a sign of a known problem?
