Do bladed spokes make a difference?
More Aerodynamic The shape of aero (bladed) spokes allows them to “cut through the atmosphere with greater ease than normal (round) spokes. (We find the same principle on Time Trial bikes which have “aero” seat posts rather than standard round ones.)
Are sapim spokes good?
Sapim spoke nipples are extremely corrosion-resistant, they are very strong so don’t suffer any damage when building the wheel, and they are shaped so that they align well with the spoke – the head can rotate a little inside the rim preventing breakages.
Do spokes push or pull?
First, spokes don’t push outward, holding the rim at bay, like it might seem. Rather, the rim is evenly pulled inward by the spokes, which are laced through the hub, the center part of the wheel that rotates around the axle. This uniformly applied tension is what supports your weight on the wheels.
Are straight pull spokes better?
In theory a straight pull wheel is quicker to build as you do not have to thread the individual spokes through the holes in the hub flanges. Another theoretical benefit of straight pull spokes is that they eliminate any inherent weakness that can be found at the bend in the spoke.
Are bladed spokes strong?
The bladed spokes are typically stronger than the butted spokes because the blade is the result of an additional forging process over the butted spoke. Most spokes are 14 gauge (2.0 mm) which is the starting point before they are butted or bladed.
Are straight pull spokes stronger?
In theory a straight pull wheel is quicker to build as you do not have to thread the individual spokes through the holes in the hub flanges. In practice there is no discernible difference in the strength and durability of a properly hand built J bend wheel and a straight pull one.
Are aero spokes worth it?
In a straight-on test, the aero spoke does better… But a spoke seldom sees the wind from straight on. Either they’re shielded by the tire/rim, or a true sidewind/tailwind means that the effective wind angle is somewhere (say 10deg.) away from head-on.
Are wheel spokes in tension or compression?
On a bicycle wheel, the spokes are thin pieces of wire. They can’t support (very much) compression, without buckling and collapsing. They can however support lots of tension (stretching). Bicycle wheels are built to take advantage of tension rather than compression.
Why do bike tires have spokes?
Spokes are the connecting rods between the bicycle hub and the rim. Their main purpose is to transfer the loads between the hub and the rim, which are caused by the weight of the rider and the bike. The lacing of the spoke is most commonly tangentially attached.
