I bought a 2004 Trek 1000 last summer, and so far I've broken two spokes (both drive side, rear wheel) in less than 200 miles of riding. After the first spoke broke, I bought some new spokes from my LBS and replaced it myself at our local bike kitchen (http://www.freeridepgh.org/). I got the wheel true laterally, but admit I forgot to dish it.
With this latest spoke, it's so far out of true (both radially and laterally) and the dish is so far off, I'm considering just having the LBS do the work. I gave it the 'ole college try for a bit over two hours, but the end result isn't pretty and the dish is still off. I also manged to strip a few of the nipples.
The wheel in question is stock, has an Alex AT450 rim, a no-name hub, and 15 gauge-straight spokes. The options I'm considering are:
1. Buy new double butted spokes, and attempt to rebuild the wheel myself (Cost: $35 for new spokes, 3-5 hours labor)
2. Have the LBS just true, dish the wheel, replace spokes as necessary (Cost: $20ish)
3. Have the LBS rebuild the wheel (Cost: $40 + $35 for spokes)
4. Buy a new wheel (Cost: $110ish for low-end)
As the bike frame/components are low-end, I don't really see the point in getting a $400 wheel-set for it (I only paid $225 for the bike), and I primarily use it for commuting to school. So I question whether a $100 wheel is going to be a significant upgrade.
My frugal and mechanical sides says option 1 is the best, but I also want to spend my time riding and not replacing spokes after a botched build. So, any opinions on which option will best get my bike in ridable shape?
Also, I'm having a rough time identifying my hub in order to compute the spoke length. As mentioned above, there is literally no name brand on it anywhere, and I don't have calipers handy for measuring. I measured the broken spoke, and it looks to line up with a 293mm. Do I just go a mm or two longer for the non-drive side?
