Most of our skeletal systems are symmetrical, and correspondingly, so are many cycling components such as bike frames, handlebars, cranks and saddles. But every now and then, one of us has an asymmetry that doesn’t fit in this world of symmetry. Resolving that conflict involves figuring out the root cause: what and where the asymmetry is, and then applying an appropriate fix if one can be found.

Figuring out the root cause is important because different causes of asymmetry, such as scoliosis, leg length difference, and…


One of our most frequently asked questions is about asymmetry, so we thought we’ll cover the key parts in this post (p.s.: everyone has some degree of asymmetry).

Imprint asymmetry

The imprints we’ve seen usually include two types of asymmetry: sideways twist, and left/right depth difference.

Picture A shows a cyclist’s imprint captured when they sat on the foam while facing forward. If we draw a line through the sitbone impressions, we expect it to be parallel to the foam’s front edge (white dotted line). …


We use custom foam blocks to capture each rider’s pressure map. Our foam has high resolution and can capture details such as chamois location with respect to the sitbones. However, before we can make use of the benefits afforded by usage of such foam, the imprint must first be correctly captured.

1. Correct imprint capture

Picture A shows an example of an acceptable imprint. It is usable by us, and is one that is

a. entirely captured by the foam,

b. not the result of the rider shifting around while sitting on it, and

c. captured with the rider sitting upright.

Once in a…


Not many people talk about well-used saddles and their repair. So we thought we’ll do that. Here’s a brief study of one of our saddles made in mid 2017 and its repair.

Photo A: For saddles that have been in use for a while, the cover may turn shiny from body contact. This can be an indicator of where the cyclist has been sitting: if only the saddle nose region is shiny, then he’s been sitting too far forward.

Photo B: For this saddle, there is noticeable abrasion on the saddle nose. The cyclist had used superglue to try and…


“What’s the problem you’re trying to solve?”

Our saddles are designed such that when sitting upright, the rider’s sitbones should be located around the widest part of the saddle. We call this the anchor location. If say the bike is too large and the saddle cannot be pushed sufficiently forward, the rider will be sitting on the saddle nose instead which is not our design intention.

The problem we’re trying to solve is this: we want to know if a rider’s bike can allow for sufficient saddle fore/aft adjustment so that she can sit on her Meld saddle’s anchor location, before that saddle is made available.

“These saddles are custom made, how is a solution possible?”

We…


Over the past few years, we have been keeping track of a particular health issue experienced by roughly 1–2% of cyclists. It appears to be pretty severe for those affected, with the more troubling part being that for roughly half of these folks, they were not aware of the problem until it was too late. So read on, because you might very well be one of them.

What’s the problem?

When riding on the hoods and tops, most cyclists’ sitbones and hence weight are supported by the saddle wings:

This is the intended and natural way to use bike saddles.

For a small…


As we end another year making anatomy-customized saddles, we pause, examine the past year, and think about what comes next.

0. Appreciation

As before, we begin by thanking everyone who used our saddles in the past year. In particular, we appreciate the efforts of those who helped us understand more about asymmetry, and those who provided invaluable feedback during beta testing.

1. Improving the overall experience

As part of our continual push to improve the overall customization experience, we regularly prioritize the issues encountered during the process. …


Every now and then, someone comes up to us and tells us exactly what he wants as the shape of his custom saddle. His expectations of what the overall process should be is different from Meld’s automated way of generating saddle models based primarily on the anatomy. After encountering a few of these folks, we think that since they own custom-built bikes, perhaps they believe our process of making custom saddles should be similar. In this article, we explain why there are differences between the two.

Information We Convey

For a custom bike built at the local bike store, we probably already know…


After observing how some riders approach saddle installation and usage, we thought we’ll put together a short article outlining a few basic considerations when determining saddle fit. Whether you’re completely new to road cycling, a professional cyclist, or just someone who’s been cycling for a while, this article is for you.

Sitbones vs Perineum

As we end another year working on making anatomy-customized saddles, we take a moment to reflect on what we think about most during the past year. We hope this article is informative and perhaps shed some light on the directions we take and choices we make. All thoughts are appreciated and can be sent to info@meld3d.com.

0. First, A Word of Appreciation

We would like to begin by thanking everyone who either purchased our saddles, were/are beta testers, or provided valuable feedback. We’ll be sure to put the feedback to good use and benefit future users.

1. Natural Bias

The phenomenon that keeps cropping up in discussions is natural…
