Website or some such I suppose

I use this to have a neb

https://geometrygeeks.bike/

Just use excel. Most bikes have geo charts with pretty similar measurements, so just plug the numbers into your own master chart. I’ve done this with my last 2 bike purchases to narrow down potentials.

Geometry Geeks is your friend.

Yes. Website called 99 spokes.

well that geometry geeks is bloody useful!

Although i currently ride a Large Norco optic, which is what they recommend for my height, but for most other brands i would ride a medium (again, according to height recommendation). These mediums are much shorter than than my Large, so i would need to size up to get similar numbers, but then these tend to be even longer….. its hard to buy a bike based off numbers and not sitting/riding them.

There’s also bike sights and you can set your reference point

BIKEINSIGHT

https://bikegeo.muha.cc/ can also be useful if you’re putting a longer fork on a bike for instance, put in most of the geo numbers and it’ll calculate the difference when making changes.

and https://99spokes.com/ as above.

hey,
bike-stats is much more detailed than geometry geeks.
An example:

https://www.bike-stats.de/en/geometrie_vergleich?Bike1=Trek_Fuel%20EX_2021_L&Bike2=Banshee_Prime%20V3_2021_L

Your are also able to adjust the drawing and add some components like stems, handlebars and seatposts.

I would point out that published geometry is often different from reality…
I’ve also found out that swapping out something as simple as a tyre can alter things a few mm’s.

I built Geometry Geeks so I would upvote it, wouldn’t I? 😉

Thx for the kind words, folks!
