What is a triple-butted tube? A triple-butted tube means it has three different wall thicknesses along its length eg 09mm/05mm/07mm
Is triple butted better than double butted?
Double butted tubes are thicker at both ends, the downtube for example where additional strength is required at the bottom bracket junction and headtube Triple butted tubes serve the same purpose as double butted tubes but further reduce weight in the center
What is triple butted Fork?
Triple butted – the tube has three different wall thicknesses; like a double butted tube, the ends of the tube have thicker walls than the center section, but the two ends have two different wall thicknesses
How much does an aluminum bike frame weight?
A comparable aluminum frame weighs around 3 lbs Complete aluminum road bikes weigh around 18 lbs On average, a steel bike weighs 1-2 lbs more than an aluminum bike Steel frames weigh more because steel is around 25 times more dense than aluminum
What is triple butted Aluminium frame?
Double butting describes tubes with two wall thicknesses; thicker at the ends and thinner in the middle Triple butting describes tubes with three different wall thicknesses along their length, optimising strength where it is needed but minimising weight in areas subjected to less stress
What is top tube on bike?
Top Tube The top tube is commonly measured horizontally from the top tube/head tube junction to the seat tube This measurement is referred to as the effective top tube length and allows a consistent measurement, even when a bike has a sloping top tube
What’s the difference between double butted and triple butted aluminum?
Double butted tubes are thicker at both ends, the downtube for example where additional strength is required at the bottom bracket junction and headtube Triple butted tubes serve the same purpose as double butted tubes but further reduce weight in the centre
Are double butted spokes stronger?
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 15mm center sections can be challenging to build at higher tension due to twisting
How much weight do 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
What is a double butted?
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 is the best metal for a bike?
Steel is the most commonly used material in bike frames Carbon or high-tensile steel is a good, strong, long-lasting steel, but it isn’t as light as its more high-tech brother, the steel known as chromoly A workhorse of the industry, chromoly is a light, strong steel
Is it better to have more or less spokes?
However, difference that is very easily noticed is durability, reliability and strength of a wheel Wheels with 36 and more spokes can carry more load, are more durable and easier to (keep) true Even in case a spoke breaks, they don’t come out of true very much and can get a rider home
What does double butted tubing mean?
Double butted means that the thickness of the tubing on the ends is thicker than in the center So there are two “butted” sides The tubing can be thinner in the middle because it takes less stress than the ends and typically you will find most breaks or cracks on frames and parts on the ends versus the middle
Are butted spokes worth it?
Yes They are a little bit trickier to build with, but the extra elasticity makes the wheels more comfortable and resilient without sacrificing stiffness
Are aluminium bikes good?
The downside for aluminium is that it can produce a slightly harsh ride quality – though some riders appreciate this Though easy to dent, it’s unlikely to fail completely – making it a good choice for road and criterium racers Good aluminium can last a lifetime – but it is open to fatigue and corrosion
What is triple butted alloy?
Butted tubing has increased thickness near the joints for strength while keeping weight low with thinner material elsewhere For example, triple butted means the tube, usually of an aluminum alloy, has three different thicknesses, with the thicker sections at the end where they are welded
Are steel bikes good?
Steel is significantly stronger and more durable than its aluminum counterpart, making it an excellent choice for mountain bikes Steel-framed bikes are able to absorb more blows with suffering damage If you are a safe rider who rarely falls down, this probably isn’t going to matter
Is 6061 or 7075 aluminum stronger?
Both 6061 aluminum and 7075 aluminum are heat treatable It is interesting to note that even though 7075 aluminum is much stronger than 6061 aluminum, it melts at a slightly lower temperature Because 6061 aluminum has a higher thermal conductivity than 7075 aluminum, it can be a better choice for certain applications
How do I know if my bike is steel?
To identify a frame firstly see if a magnet sticks, if it does it’s steel, if not it’s carbon, aluminium alloy or titanium alloy If not steel look down the seat tube if it’s metallic inside it could be aliminium or titanium if black and plastic looking, carbon
