I've been through a couple back wheels. The first one was because it was a stock Bontrager Race Lite 24 spoke count wheel that the LBS said would be fine. The next one I trashed because I did some DIY wheel truing and over tightened the spokes and cracked the eyelets. Now they set me up with what they said was a nearly indestructible wheel. Velocity Dyad 36 spoke count. It hasn't had any major issues but it does lose it's true after about 3-4 commutes (32 miles round trip). The LBS built the wheel, the LBS trues the wheel....but that just doesn't seem like a good hold of true. What are your thoughts? Do I need a better wheel? A better re-tensioning of the spokes? What?
I have disc brakes (Trek Portland) so I do have some leeway before it hurts the bikes performance. Also, my hubs are DT Swiss mountain bike hubs 340 or 440...can't remember right off the top of my head. When I commute to work I have full, double sided panniers with clothes, gear and laptop computer. The total load with me and all the stuff I carry on the bike is probably 350 pounds. Please let me know your throughts. The front wheel has been perfect and barely ever needs truing.
