Hi Jon,

As i feel a bit of a catalyst for this post, I'm happy for you to use my Ventum One, when it arrives at Greg's studio, so you can take the measurements in person.

I'll shoot you an email separately.

Cheers,
Jimmy

Pad x to rear, Y incl cushion

Thanks for sharing, our numbers are close, but I think you are missing a frame size and you didn't account for the cockpit going rearwards as you add more stack to the spacer stack beneath the stem.

Sorry, haven't updated the chart since they added the 46. Also, I've never seen anything to suggest that the bikes arrived with room to move up the steerer (none of my clients have acquired one of the bikes). Does the steerer come uncut? I have most of the required dimensions from the bar drawings so the numbers should be fairly accurate.

Funny, this reminded me of a post I made that Jimmy replied to over a year ago now. I've not checked their page in a while but it sounds like they never got around to it?

Hello Jonathan,

Thank you for the note on Handlebar X/Y. We have just launched our new Z range with a 3T handlebar which has a wider fit range than our standard bar. I have the fit data below. I hope this helps.

The updated Ventum One handlebars allow for mounting the extensions under the base bar helping with a lower stack.
