Bontrager Select spoke tension?
Kerry Montgomery
I've had some trouble with non-drive side spokes loosening on Bontrageer
Select rear wheel. Couldn't find specs for spoke tension on the web - does
anyone here have any info?
Thanks,
Kerry

Dear Kerry,
The Select wheel has vanished down the memory hole at the Bontrager
site.
The internet offers a wonderful illustration of how meaningless
recommended spoke tensions can be. This site collected a lot of
manufacturers' recommendations:

The Bontrager select wheelset spoke tension was anywhere from 50 to
132 kgf for all spokes, front and rear, which isn't terribly helpful.
Cheers,
Carl Fogel

Carl,
Thanks for the link - you're right, Bontrager's specs aren't very helpful.

If you think the wheel is otherwise stiff enough, tighten up the loose
spokes with some glue in the nipples.

I don't have the specs, but as it's been pointed out they're not
terribly helpful anyway. They wouldn't be in the owners manual of a
bike that comes with them stock, would they? I have the manual to my
road bike, which has those wheels, at home. I've never even thrown
the disk into a computer, so I couldn't tell you what's on there.
I'll try to remember to check tonight.
One thing I do know is that the tension is high. Surprisingly high.
The tightest spokes I've ever had, actually. Normally I stress
relieve and tension any new wheels I get, and do my own wheel truing
and maintenance. Spoke tension is so high on these, combined with the
low spoke count and how far away they are from each other, that I
never touched them with a spoke wrench. When they do need attention
I'll probably bring it back to the LBS, something I'd normally never
do for something as trivial as truing a wheel.

Get your driveside up to 100-120 ish which is a normal DS tension, and
the NDS whatever it takes to dish. If the spokes still loosen, just
use a locking compound on the threads. Loctite or DT spoke prep or
even linseed oil.

news:8-udnXtW4oZ6ghTU...@earthlink.com...> Hi all,
Kerry: The issue is that non-drive spokes on low-spoke-count wheels
often don't hold their tension without help, and that help comes in the
form of wicking loctite. Wicking because standard thicker loctite won't
get into the threads after assembly. People will argue that it (loctite)
shouldn't be needed, but experience shows that wheels of this type hold
up a lot better with loctite than without. What we've found in our shop
is that it's essential to re-apply loctite to any spoke subsequently
trued.
Hope this helps-

Thanks to everyone for the suggestions.
DanKMTB, if your owner's manual has any info, that'd be great. I bought the
wheels separately (I think they were take-offs), and they didn't come with
any documentation.
I'll check the DS tension and take them to 100ish, and see what the NDS ones
then look like.
Thanks again,
Kerry

I've ridden many years over many roads, here and in the Alps and never
had spokes loosen, but then I don't have 10-speed clusters that
require huge dish, and I use too many spokes for today's folks. I
recall when Wheelsmith had to invent SpokePrep to make up for their
early machine built wheels that were too loose from the start.
If you gotta have it, don't complain. The more gears you have the
easier climbing hills becomes, as the man on the street believes...
especially if you can shit without letting go of the bars and while
pedaling hard.
Everything on bicycles is getting better, or is that just more
expensive.

Irritable bowel syndrome can produce undesirable results in people who
are aerobically overextended. I wasn't aware it was of significant
concern to drivetrains though.

Sorry 'bout that. The word should have been SHIFT, but then you knew
that.

Hi Kerry,
Checked that manual for you. It was as useless as expected. Torque
specs for seat post clamps, stems, etc. but nothing about the spokes.
Sorry I couldn't be more help.
