Numerous Spoke Breakage, Why?
I’ve heard some Spesh wheels are prone to breaking nipples as well, got a friend who’s had a complete set of wheels replaced under warranty and has now the replacements rebuilt using brass nipples as still suffering breakages. (under warranty too!)Posted 8 years agolank45Member
I’ve had a number of spokes break in my front wheel over the last couple of months. Is there anything this could be down to? The previous spokes have been replaced at the LBS, but after a few weeks another spoke will break. Is it time for a new wheel build replacing all the spokes or could it be down to something simpler?Posted 8 years agoSamMember
Poorly built wheel. The most likely cause is not enough tension in the spokes and/or the wheel not having been properly stress relieved during the building process. Time to find an lbs which knows how to build wheels. A well built wheel with quality spokes will not break spokes unless they are subjected to some external damage.Posted 8 years agosimon1975Subscriber
No-one’s answered the OP’s question yet. Once you’ve broken one spoke, the tension immediately transfers around the rim into the adjacent and opposite spokes, and tension will be lost on the horizontally “perpendicular” spokes.
So when the broken spoke is replaced, it’s important to re-set the tension on ALL the other spokes in the wheel – and then re-true it. Otherwise some spokes will end up too tight, and some too loose, and they’ll keep breaking.

This is spot on and is almost certainly the cause.
Loose spokes flex at the elbow and fatigue then break very fast. Your wheel was almost certainly built loose and the spokes are all starting to break through fatigue. There’s nothing that you can do to stop it other than have them all replaced as even the ones that haven’t broken yet will have been damaged and you’ll continue to break them as you ride the wheel.
Suggestions that it’s anything to do with spokes too tight, alloy nipples, etc are incorrect. I build a lot of wheels and all of them are built very tight and I regularly use alloy nipples. Spokes built properly into a wheel last almost indefinitely (I have wheels with 10 year old spokes that have been on 5+ hubs and similar if not more rims with no breakages).Posted 8 years ago
