#TOURING BIKE WEIGHT WINDOWS#

The Logo Titanium, is the same design and there’s just the difference in metals. The Tubus Logo in Cr-mo, which we supply with every Vivente bike, with the mounting items, weighs 738g and is rated to carry 40kg. How Much Weight Can a Touring Bike Carry? Pretty soon though, it is not a touring bike.

No kickstand, no mirror, no dynamo hub, no pannier and so on. We want the function over the speed.Ī simple way to save weight on a touring bike is to leave things off and to talk about lightness as if it is a virtue. But when we are touring, we don’t mind if drag on the heavier front dynamo hub caused us to arrive 6 minutes later than we might have (2% extra energy used at 20kmh over a 100km day).

In competitive cycling disciplines such as road, track and cross country MTB racing, weight is a big issue. An obsession with weight would have been likely to get in the way of that. On our bikes, in traffic, or coming fast down mountains, we need to be able to trust that defect tolerance has been factored in. There is a term “defect tolerance” used in engineering. Space programs burn up billions of dollars but still have catastrophes happen when something as simple as an O-ring has a tiny flaw.

The glass in a window has over five times the tensile strength of cr-mo steel but windows readily break.ĭefects in manufacturing are unavoidable. Frames and parts fail due to fatigue, lack of toughness, “notch-sensitivity”, or in an impact. It is often mentioned but bike frames don’t fail in tension.

A good example is that of tensile strength. We are wary of allowing marketing language to distort the design story.Īnd there can be distortion in marketing statements about bikes. We wanted to leave the word “weight” for its own page as we do not make decisions in frame design and material selection, based on weight. The need to make non-competition bikes lighter has often been exaggerated in the media and the marketplace. We are highly conscious of touring bike weight but it is an end result rather than a starting point. Our major design criteria have been quality, efficiency, comfort, durability, serviceability, longevity, safety and value for money.
