A new bike geometry database & comparison tools
Quote | Reply
Hello slowtwitchers

We're making a new thing - a wiki-like database of bike geometries that lets you compare bikes side by side.

It's at geometrygeeks.bike - we're over 1200 bikes now, and growing daily. Add your own, maybe?

We're looking for feedback.

It's fair to say it's not yet optimised for Tri/TT bikes... that's where you come in. What works, what doesn't? What features or parameters would be useful? All comments, positive and negative, gratefully received.

Please post on here, email us at hello@geometrygeeks.bike, or sign up to the newsletter on the site if you just want to keep an eye on us ;)

Cheers!

Bob

PS full disclosure: it's a spare-time project by a pair of geeks. However, at some point we may try to generate some revenue from ads or premium features or something. Basic access to the data will always be free.

Some kind of filter would be nice (kind of like a price filter in an online store).

Also, the pad x/y measurement range is a bit more useful for triathlon than the frame stack and reach. It would be cool if you could include those by doing the calculations based on the existing measurements.

I would love to see a database showing also the effective seat tube ranges. How far can fit get with available seatposts and saddle rail.

Thanks, all. We'll have a think about how we might be able to add pad x/y and seatpost range calculations.

Thanks to to those of you who added bikes :)

I'd go further than to say that pad x/y is just useful, it is absolutely key with some Tri bikes. If are putting on an aftermarket bar and stem then you can figure it out fairly easily from the frame stack/reach, but if the bike comes with proprietary bars then it is much harder. An example being Ventum, who have their own bars and publish frame stack/reach but don't tell you the range of dimensions that their bars can offer (as far as I can tell, happy to be proven wrong).

The problem of course is that you don't always know what bars are going to be used on a particular frameset, in which case pad x/y isn't so useful. But if the bike has the bars integrated then it is crucial. Canyon provide pad x/y for the TT bikes.

Ideally you publish frame stack/reach and pad x/y, when a set of bars are included. But then some manufacturers probably spec different bars with basic vs premium in the same range which makes it a proper pain! You kind of have to say what bars the x/y are based on.

Thanks knighty76 - we'll have a think about how we manage this complexity!

For the moment, we have added the ability to enter Pad reach (x) and stack (y) and seatpost offset.
