What does triple butted frame mean?
A triple-butted tube means it has three different wall thicknesses along its length e.g. 0.9mm/0.5mm/0.7mm.
Why is a double butted frame good?
There are two methods used to butt a frame tube. Double Butting—As the tube is shaped, extra material is allowed internally at each end of the tube. By increasing these areas of the tube, the overall tube wall thickness can be reduced, thus saving weight.
What is triple butted Fork?
The squeezing down results in the wall thickness increasing at the narrowest part of the taper. Some might describe this as “butting” the end of the taper, and you might even go as far as saying the fork blade is “triple butted”, since it is likely that fork tip will have a different wall thickness than the other end.
What is a triple butted spoke?
Triple butted spokes are thickest at the hub end, thinnest in the middle, and in between thicknesses at the rim. Triple butted spokes are mostly used in high load applications. Straight gauge spokes are one thickness straight the way through.
What does butted mean in bikes?
Butting a tube refers to changing the tube’s wall thickness by removing excess material that isn’t needed for strength or performance.
What does double butted frame mean?
Double butted means both ends of the tube are thicker, single means only one end is thicker than the middle section. There is even triple and quad butted. Triple means each end is a different thickness.
What does double butted bike frame mean?
Double-butted – The tubes are thicker at each end to provide additional strength at the junctions but thinner in the middle to reduce weight. A frames down tube is most commonly double-butted.
Are double butted spokes better?
Double butted spokes are lighter than straight gauge and offer better ride qualities due to a more flexible center section.
