... or what makes a flat bar flat?
I've got a lovely Spank Oozy low riser bar on my bike; it has a small 5mm rise (its geometry is described as 4° Up and 6° back).
I've been having a look at some carbon flat bars and have been getting a tad confused about all the values. [url= http://www.superstarcomponents.com/en/helium-carbon-flat-bar.htm ]Superstar's Helix flat bar[/url] is described as having 0° rise and 5° upsweep; can a bar have upsweep but no rise and just to confuse things further, [url= http://www.ninerbikes.com/carbonhandlebar ]Niner's Flat Top bar[/url] (the name suggests it's flat) has a 5mm rise. [url= http://www.chainreactioncycles.com/thomson-cross-country-carbon-flat-bar/rp-prod91740 ]Thomson's flat bar[/url] supposedly has an 8mm drop if reversed.
Am I confusing upsweep with rise and what differentiates a flat bar from a very low riser?
Rise is how far above the centreline of the bars at the stem the component mounting/narrow bit starts. Upsweep is the angle the component mounting/narrow bit deflects from horizontal. Back sweep is the same but from perpendicular to the bike frame axis.
Got that, thanks.
