Specialized Ruby Expert women's saddle



Super light, firm but comfortably supportive road saddle with width fittings to suit most riders

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Specialized's Body Geometry Ruby Expert saddle is one of those rare beasts a lightweight women's specific performance saddle that's available in a choice of widths including a properly narrow 130mm to suit your style of riding and just as importantly your sit bones too.

Inevitably one person is going to have a very different definition of comfort when it comes to bike saddles than someone else, so ultimately personal trial and error is the only way to find your perfect saddle. That said, there are marked differences between the requirements of men and women, when it comes to this most crucial interface between man (or woman) and bicycle, and it's important to take that into account when shopping around.

There's an assumption that women are broader in the hip than men, which is not entirely without basis in fact, but the important measurement for getting a comfortable saddle is not the breadth of the hips, but of the sit bones themselves, a width which often bears absolutely no resemblance to that of the hips. It is these sit bones which are cupped and cushioned by the saddle, so an appropriate width of saddle is vital.

Getting measured is a good place to start, and Specialized's Body Geometry Saddle Fit System (rather more catchily also known as Arse-o-meter) is available in quite a few retailers allowing for an accurate measurement of those all-important bones. From here it's easy to get a saddle the right width but it's still all about personal taste and riding style as to what works for you, so back to that trial and error. The Ruby Expert from Specialized is available in a choice of 130mm, 143mm or 155mm width, making it one of very few narrow width female specific saddles, and also one of few ultra-light race saddles available in such a broad fitting.

It's a firm saddle, but very light. In comparison with most female specific saddles, it's a pared down seat, ideally suited to aggressive road riding and racing. With the trademark BG cut-out, it's designed to relieve pressure where it's needed without sacrificing ride efficiency. Hollow titanium rails help keep the weight down, and at just 205g for the 143mm size that I tested, it's definitely one of the lightest women's saddles on the market.

On first climbing aboard, I had some trepidation due to the firm feel of the saddle, especially in comparison with other saddles, including the cheaper Jet Comp Gel. However, it was soon clear that this was a different breed of saddle entirely. Yes, it's firm, but the cushioning is placed exactly where you need it to support your sit bones, effectively alleviating any discomfort or feeling of pressure. Where the Jet Comp Gel was over firm at the nose, the Ruby Expert is much more gentle where it should be, even in an aggressive position on the drops. This saddle is at its most comfortable when riding in a stretched forward position, but still gives all-round day long comfort too. There was little feeling of loss of power, with the saddle remaining a background feature of the ride, rather than making its presence actively known. Given the choice of widths, this is a good option for any female road rider looking for a comfortable performance saddle. At this price, it's comparable to most of the best women's saddles available, and certainly isn't bad value for money.
