dgk said:I broke a spoke this morning on the way in to work. Or, I should say,
another spoke. It's a Trek 7100 hybrid with a pack on the back so
there is a lot of weight on the rear wheel and that's where the spokes
break.
I break at least three a year, or more. Often in bunches, I broke one
a few weeks ago. I tried squeezing them a bit every week or so which
is supposed to ward of breaking spokes.
Hard to diagnose what the problem is, but it may be the "squeezing them
a bit." Put on some leather gloves and squeeze the [censored] out of adjacent
spokes. You should only have to do it once. From the above, I'd guess
you need more tension on the whole wheel, and stress cycling is killing
the non-drive spokes -- tighten or get it tightened before the
stress-relief.
Quoted message said:Now I'd just like to put a good wheel on the back and stop breaking
spokes. Is it better to get a wheel with fewer spokes but thicker?
Suggestions are open. I'd like to keep it cheap, but it's the one
thing I really dislike about commuting by bike and will spend what it
takes to get one that won't break. Thanks.
You need a good wheelbuilder. (That can be you, with Jobst's book or
Sheldon's site, plus a spoke wrench, a truing stand and a tensiometer.)
Not everyone who builds and/or trues wheels is a good wheel builder, alas.
I out-weigh you by 50% (but coming down, slowly!), commute on a touring
bike, and I can tell you it's possible to build wheels that don't break
spokes. I had one wheel that was problem-free for 4000 miles. (Then
the derailer dived into the spokes, and I found out I should have been
repacking the bearings.) As you note, front wheels are easier. I
retensioned my front wheels about 10,000 miles ago and haven't messed
with them since.
Peter, Sheldon and/or Jobst may jump in Real Soon Now and tell you their
recommended components. As for cheap, well, depends on your definition.
Good parts, you can probably put a solid wheel together for ~$125-150
if you DIY. Add in $25 for the book, $30 for a truing stand (on sale),
$5-10 for the spoke wrench, and $60 for the tensiometer.
If you go to a good wheel builder, they'll recommend components for your
use, and it'll probably run you $250 or so; they'll sell you parts at
full retail and add a labor charge for building the wheel. I got one
from a well-respected builder last year, put 2400 miles on it so far,
and had to touch up a couple of non-drive-side spoke's tension earlier
this month, but that's a whole lot easier than replacing a spoke.
(Think Christmas present! I ordered it and my wife paid the credit card
bill. 🙂
