Breaking Spokes(5 posts)

I have a set of 32 hole Mavic Open Pros on Campy Record Hubs, DT 14 gauge spokes, 3 cross. The set was built by whom ever at Excel. I am continually breaking spokes on the rear wheel drive side, one or two at a time. I weigh about 180 lbs. Thought about having the drive side respoked with 15 gauge, any ideas???

probably not enough tension in the rear wheel. Also, straight gauge spokes are more likely to brake then butted versions - the thinned out section of the spoke provides elasticity, allowing the spoke to flex there rather than move in the hub under stress. Stick to butted spokes and have someone qualified check/rebuild your rear wheel.

I have a big friend who also breaks a lot of spokes on his Excel built rear wheel. Definitely check the tension and stick with butted spokes like the other poster suggested. Did they break at the heads? Pulling or 'pushing' spokes?

Are they breaking at the bend or a little way down the spoke? Has your rear derailleur ever thrown the chain into the spokes? even if it didn't break the spokes when it happened, it will still damage them. If it is at the bend then it is like the other posters said...to little tension.

Remember, 15 gauge = 1.8 mm diameter, while 14 gauge = 2.0 mm. Reverse of what you might think. Even so, a 15/16 butted spoke in your wheel would be fine if there is enough tension. Per other posters, it sounds like there is not enough spoke tension, the most common cause of spoke breakage (absent mechanical damage to the spokes).
