|Ritchey wheels - replace spokes or rebuild||newhouse|

|my specialized allez a1 came with ritchey aero ocr wheels with 28 bladed spokes in the rear. i have about 3000 miles on my rear wheel and i have recently broken a few spokes - once while riding and the other while just pushing the bike out the door. should i continue to replace the spokes as they break or have the wheel rebuilt? i was thinking of rebuilding it with the regular spokes.|

|Where are you breaking these spokes? Drive or non-drive side? And what got into your spokes in a past ride?
Don't rebuild with regular spokes if you are breaking spokes... bladed spokes are almost 3 times stronger than round spokes. How big are you? If you are breaking spokes on this wheel.. you may need to go with a more conventional 36 spoked wheel. Also, more importantly than your size is your riding style. You can be 300 lbs. and never break spokes if you ride right. Do you have a tendency to try to bunnyhop curbs or potholes? If so, that could be what is killing your wheel. If you ride over bumbs and rough roads, do you get up off your saddle slightly and absorb the bumps with your knees bent? If not, you should. Anytime you ride over rough or bumpy roads, relax your elbows and knees and soak up the bumps.
But if you threw your deraileur into your spokes it may have weakened your spoke to the point of failure. But the problem here is not the bladed spokes themselves... they are stronger than round spokes.

|thanks for the reply and here's some additional info. the two spokes i have broken are on the non-drive side and nothing caused them to break. i am 160 pounds and i really baby my bikes (ie. no bunnyhops, no potholes, no rough roads, etc). since you say the bladed ones are not the cause, i'm probably going to just replace the one broken spoke i have now and see what happens.|

any tests about that?
are they more elastic?

|Think about it this way. If all that you do is to replace the broken spoke and retrue the wheel, you will be returning your wheel to exactly where it was before the spoke broke. In other words, a wheel that is about to break a spoke.
You need to have your wheel retensioned. If I were doing it, after I replaced the broken spoke, I would loosen every single spoke until I could see just one thread, then gradually bring the wheel back into tension. Finally, I would check every single spoke with my tensiometer and retrue the wheel. By way of comparison, all of this would take me at least 30 to 45 minutes and I can build a wheel from scratch in about an hour.
By the way, I think the talk about bladed spokes being stronger is irrelevent. If spokes broke due to tension, all of the butted spokes would break in the skinny middle part. That doesn't happen.

|Breaking NDS spokes is nearly always a sign of inadequate spoke tension, allowing the spokes to go slack with each revolution of the wheel. This means the spoke heads will move at the hub, and it's all downhill from there. If this is the case, chances are good that there are other spokes waiting their turn to pop. Put the wheel in proper tension, and if you break more spokes, it's time for a rebuild.|
