|I am having some consistent problems with my rear wheel and am not sure were to go from here.
1) The spokes keep breaking 4-5 in the <3500 miles
2) Spokes keep coming loose (at least I assume this is the problem based on the horrible popping clinking sound the wheel makes).
I can tighten the loose spokes and bring the wheel to even tension. However, it does not seem to want to stay there.
Is it possible that the wheel was built wrong and the only repair is to start over?
|Sounds like the non-drive side is too loose.||dzrider|

|I'd loosen all the spokes and start over. If you've broken 4 or 5 and spokes keep coming loose, you've already wasted more time than it would take to go back to the beginning.|

|You may want to check to see if the wheel is centered first. I use a dishing tool for this. See www.parktool.com|

|Are the spokes name brand?|

|You didn't say whether the broken spokes were on the drive side. With 9 speed wheels, the non-drive side spokes can be so loose that they actually go slack wwith each revolution of the wheel. That leads to early fatigue failure. If the non-drive spokes are failing, the best solution is to respoke the non-drive side with a lighter guage spoke. If the wheel is all straight guage now, respoke the non-drive side with double butted. If the wheel is already double butted, repoke with DT Revolutions, which are even thinner than standard DB spokes in the butted section, or respoke the non-drive side radially. The lighter guage spokes will stretch more, and will not go slack as heavier spokes will.|
|Assuming quality parts, it's all about spoke tension||Kerry|

|If the wheel is a decent rim, hub, and spokes, then the problem is most likely inadequate spoke tension, which explains both the breakage and the loosening. At this point, the rest of the spokes have been pretty worked over, so I would suggest a rebuild (new spokes) with a competent builder. If on the other hand, you've got all low end stuff, and your weight is up there, you need a new wheel. Give us some details and we can take it to the next step of recommendations.|

|The spokes have broken on both sides of the wheel. I think 2 on each side.
The wheel is pretty low quality. Tiagra hub laced to a Alex DA22 rim. It is my first road bike and I am trying to strech the bike till the end of the year when I upgrade to someting more serious. I had no idea I would really get into this and start riding 100+ miles/week.
As for weight I am presently 169 down from 195+ and still falling with a target of around 155-160. In addition I primarly ride this bike for commuting (11 miles each way) so I add about 15lb in bags on the back.
Thanks alot for the help.
