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.

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.

Look back few pages I posted about the T4 bar and shown the actual measurements. I still use the bar on my bike, but the up sweep is not for everyone.
What does it mean, the up sweep is not for everyone ?
I am looking handlebar what is exactly 80mm from centre to centre. I saw your pictures, if you have 110mm stem length, it seems 110mm from centre to the centre, correct ?
Now, I have 90mm stem, and the whole measured stem from up to bottom is 150mm. According to your photos, you have 110mm, and from up to bottom you have 170mm, So from centre to approx centre is exact what I need ? Thanks for confirmation !
PS. I dont need stem which is the same length as my current stem , ofc, and I'm trying to measure it exactly as they say on the website.

I know it’s not a handlebar on your list, but it’s the one I use, so I can share my experience. I have the Lexon Thin Line handlebar https://it.aliexpress.com/item/1005010706794452.html, 380 × 100 mm, and the dimensions seem right to me. I’m attaching a photo.

I saw the lexon, very nice, but it has reach 80mm, and I am looking for something shorter (now I have 78mm and 90mm stem and it is long for me). So 80mm stem and <75mm reach is better for me

Hi guys, have a problem with selection of correct handlebar cockpit.
I have now Merida Reacto 2026 in XS, which is with stem 90mm length (MERIDA EXPERT SL 2P), and Merida Expert CW handlebar (78mm reach) and I think and from my bikefitting, I need 80mm stem with shorter reach on handlebar. I already read the whole internet and my selection of cockpits are:

1. rolling stones, raech 75mm, 80mm stem, and should be nice compatible with merida reacto https://www.aliexpress.com/item/1005006645688485.html?pdp_ext_f=%7B%22sku_id%22%3A%2212000037913790214%22%7D&sourceType=1&spm=a2g0o.wish-manage-home.0.0#nav-specification

2. the ONE ultra, 73mm reach, 80mm stem but 13mm lift the upper handle https://www.aliexpress.com/item/1005003968726979.html?spm=a2g0o.productlist.main.1.69287TAO7TAOjk&algo_pvid=d8c9bc00-020c-4147-a374-01597c8bfab8&pdp_ext_f=%7B%22order%22%3A%22155%22%2C%22eval%22%3A%221%22%2C%22fromPage%22%3A%22search%22%7D&utparam-url=scene%3Asearch%7Cquery_from%3A%7Cx_object_id%3A1005003968726979%7C_p_origin_prod%3A

3. T4 ultra handlebar, reach 70mm, stem 80mm, again 13mm lift the upper handle https://www.aliexpress.com/item/1005009212475134.html?spm=a2g0o.productlist.main.1.7736hqN3hqN326&algo_pvid=2bf833e1-2a3e-4afb-be9d-5c62e7bc42e6&pdp_ext_f=%7B%22order%22%3A%2227%22%2C%22eval%22%3A%221%22%2C%22fromPage%22%3A%22search%22%7D&utparam-url=scene%3Asearch%7Cquery_from%3A%7Cx_object_id%3A1005009212475134%7C_p_origin_prod%3A

4. lightcarbon HBR17, reach 75mm, 80mm stem, https://www.lightcarbon.com/ultra-light-and-aero-carbon-road-integrated-handlebar_p257.html

My question is not about what should I buy, but I need to know one thing. I read on the most forums, that some of these cockpits are 1cm longer than described., that's why I had to remove Tavelo Rise from the selection (tavelo official partner answered, that 80mm is like 90mm).

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 ?

Thanks !
