Re: Recommendations for integrated handlebar?
So my question is, what is 80mm real stem length ? If you guys have some of these handlebars, could you please measure that and tell me ? The pitfall in practice: When a manufacturer measures the geometry from the bottom, an aero stem specified as "100 mm" might actually be 110 mm long along the top edge. So, if you are switching from a standard stem (measured center-to-center) to an integrated aero cockpit, you should carefully check the manufacturer's geometry charts. Otherwise, you might end up stretched out 10 mm further on the bike than you originally intended. For instance, the specifications for the T4 Ultra handlebar and The One Ultra are indeed measured from the bottom. However, there are exceptions to this rule: my LightCarbon HBR17 measures exactly 100 mm from the top, which perfectly matches the manufacturer's specifications. June 09, 2026, 11:46:44 PM |

Re: Recommendations for integrated handlebar?
It is very strange, that T4 or ONE ultra handlebars are longer (measured) from bottom. Because I saw their description and it seems that they are measuring from centre to centre. So i am a bit confusing. Dont want to spend money for cockpit, what is exactly as I have now. So that's why I'm asking around on the forums and finding out as much information as possible. I think there might be a slight misunderstanding about what I meant! To clarify: When I say it is "measured from the bottom," I mean that the manufacturer specifies the size (for example, 100 mm) based on the length of the bottom edge. Because of the downward angle and the thick shape of these aero carbon stems, the top edge is physically longer than the bottom edge. Here is how it plays out in reality: If the official spec (measured at the bottom) is 90 mm. The measurement at the top edge will actually be around 95-100 mm. This means if you order a "90 mm" T4 Ultra or The One Ultra, you are practically getting a 95-100 mm stem (if you measure it from the top, the way we are used to with standard stems). That is exactly why the sizing is so confusing and why many people end up with a cockpit that stretches them out much further than expected! To show you exactly what I mean, I am attaching two photos of a 90mm T4 Ultra here. As you can see in the pictures, the bottom measures around 90 mm, while the top is around 95–100 mm.
