Inhoudsopgave
Waar wordt de Batavus fiets gemaakt?
Batavus is een Nederlands fietsenmerk, dat in het verleden ook bromfietsen en motorfietsen produceerde. Het bedrijf is gevestigd te Heerenveen.
Welke maat van fiets moet ik nemen?
Meet de afstand vanaf uw kruis tot aan de grond dit is uw binnenbeenlengte; Deze lengte in centimeters maal 0,66 is voor u de juiste framehoogte; Zit u exact tussen twee framehoogtes in dan kiest u bij een stadsfiets voor de hoge framemaat. Gaat u uw fiets meer sportief gebruiken dan kiest u de lagere framemaat.
What is a double butted frame?
If tubes have only one dimension along them, we refer to the frame as being butted, if it they have two dimensions (being thicker at the tube ends and thinner along the middle) then we are talking about double butted frames.
What is the difference between Single butted and double butted tubes?
Straight gauge tubes don’t have any varied tube thicknesses providing consistent strength properties, whereas as single, double and triple butted tubes create different thicknesses that allow the frame to handle high-stress points at the end of the tubes without having additional weight through the middle.
How do you increase the diameter of an aluminium butted tube?
The mandrel is removed after reeling the tube between angled rotating rollers, which increases the diameter while having a negligible effect on the wall thickness. Finally, the outside diameter is sized by pushing the tube once again through a die. The processes above can also be applicable to aluminium butted tubes.
Are there alternative processes for aluminium butted tubes?
The processes above can also be applicable to aluminium butted tubes. Reynolds developed alternative processes for titanium mandrel butting, magnesium mandrel butting and the latest product, our Maraging 953 stainless steel. Each of these products have specific technical challenges that required innovative techniques to be used.
