How much weight does double butted spokes save?
Replacing 32 straight gauge spokes with double-butted spokes gives almost the same benefit of 36 straight gauge spokes, but for about 70 grams less. The extent to which load is shared between neighboring spokes depends on the ratio between the rim stiffness and the spoke stiffness.
How much lighter are double butted spokes?
As already mentioned, a double-butted spoke is a few grams lighter than a straight gauge one. This result is a wheel that’s about 5% or so lighter than its counterpart built with plain gauge spokes.
Are double butted spokes lighter?
Double butted spokes are lighter than straight gauge and offer better ride qualities due to a more flexible center section. Double butted spokes are generally very strong, however spokes with 1.5mm center sections can be challenging to build at higher tension due to twisting.
Are butted spokes worth it?
So no one makes good quality ones. Double butted spokes … not only save weight over plain-gauge, they add strength because the thick ends make them as strong in the highly-stressed areas as straight-gauge spokes of the same thickness, but the thinner middle sections make the spokes effectively more elastic.
Are butted spokes stronger?
Butted spokes are stronger than straight-gauge or bladed spokes. Butted spokes have a thicker end section where it is braced against the inside of the dropout, and they have a thinner middle part that goes into the hub.
What does double butted spokes mean?
Double-butted spokes: These are lightweight spokes that are thinner in the middle (e.g going from 2mm to 1.8mm and back to 2mm again) to save weight and reduce ride stiffness, without compromising on wheel strength.
Why are butted spokes stronger?
The strength of spokes varies depending on their materials. Steel is stronger than aluminum, for example, so we can say that butted spokes often have more strength than regular ones because they’re usually made from steel which has increased tensile yield stress (it takes more force to bend it).
How much does a double butted spoke weigh?
DT Swiss’ most popular double butted spoke was designed for all-purpose use where weight, strength and cost must be balanced. Typical applications range from mountain bikes, to road racing, to tandem and commuter use. Weight: 32 spokes weigh 191g (32 x 264mm); 5.97g / spoke
How can I save weight with spokes?
There’s two ways to go in terms of saving weight with spokes: use less spokes. Obviously, you could do both as well – less spokes and lighter spokes. How much weight can I save? spoke from which weight savings are calculated is the DT Swiss Competition double butted spoke; How will lighter spokes or less spokes affect the wheel?
What are the DT Swiss revolution spokes?
The DT Swiss Revolution is an ultra-light double butted spoke that uses a 1.5mm diameter center section to achieve weight reduction. Using Revolution spokes is an easy way to drop extra grams from your wheelset .
How much less stiff are butted spokes under radial load?
The butted spokes in our example calculation are 19% less stiff than the straight-gauge spokes. Under a 50 kg radial load, the bottom-most spoke sheds 23.82 kg and 22.68 kg in the SG and DB wheel, respectively. This difference (1.14 kg) works out to a 5% reduction in the stress change seen by the spoke.
