|Can I make my wheel stiffer?||Qubeley|
Feb 26, 2003 3:26 PM
|I have a Ritchey WCS front wheel, 16 aero spoke.
When I sprint, I am able to notice the flex coming from the front end. The spokes seem to have a very low tension. (I am positive it's not from the handlebar or fork)
I am just wondering if I can make the wheel stiffer by tightening the spokes a bit more, even though the wheel is factory built.
Do you think it will work?

|If the spokes truly are "very low tension" then the wheel will be laterally stiffer when brought up to the correct tension. OTOH, a 16 spoke wheel must have a very deep section and stiff rim in order to be laterally stiff. Plus, with only 16 spokes, the average spoke tension will need to be very high - roughly 2X that of a 32 spoke wheel of comparable stiffness.|

|That's why I asked.
When comparing this wheel to my other wheels with higher spoke counts(Helium or open pro-dura ace 3x), the spokes on this wheel have A LOT more flex when I press them with my finger, even though it's fewer in numbers.
The rim of the wheel isn't that deep, only 28mm.
I'll bring it to LBS this week, let's see..

|The scientific answer is:
"Wheel stiffness does not vary significantly with spoke tension unless a spoke becomes totally slack."-Damon Rinard. Check it out (with graphs and everything)at: http://www.sheldonbrown.com/rinard/wheel/index.htm
However, if you believe the wheel is under-tensioned, you should definitely have a competent wheelbuilder take a look at it. As the previous poster mentioned, low-spoke wheels rely upon high tension for their structural stability much more so than traditional wheels.
