A Look at Rivet Saddles

Rivet Saddles

When I last corresponded with Debra Banks, she was off to ride the Texas Rando Stampede 1200 - a 750 mile brevet that she would go on to complete in 85 hours. Naturally Deb did this on a Rivet: a waterproof, slotted leather saddle of her own design.




While Rivet saddles are fairly new to the scene, Deb's experience in the industry goes back to her time at Selle Anatomica. In her own words:

Tom Milton, the founder of Selle An-Atomica was my sweetie and after his untimely death, I ran SAA for a year while his estate was being settled. His family took over the company and I ventured out on my own to form Rivet Cycle Works.

At the moment, Rivet offers three basic models of saddles in different widths. Each is available in a range of colours, and with a choice of cro-moly or titanium rails. We discussed my trying one for review and settled on the Pearl.




Rivet Pearl Saddle

Named after Pearl Pass in the Rocky Mountains, the Rivet Pearl saddle was optimised for long distance comfort and support. As Debra explains, this does not mean these saddles are solely for long distance riders. Rather, if a cyclist experiences saddle discomfort when attempting longer rides, it was designed with addressing this in mind. The Pearl model features bag loops for attaching a full sized saddlebag.

Measuring 170mm at the rear, the width of the Pearl is equivalent to that of Selle Anatomica saddles. However, the shape and structure are quite different. In fact, while Rivet saddles may invite comparisons to Selle Anatomica because of the shared history, I find them to have more differences than similarities. The list of similarities is short: Both are slotted, and both are made of waterproofed leather in largely the same range of colours. However, the form and feel have little in common.

The first thing I noticed about the Pearl before fitting it on my bike was how tall it was. The height, or depth of a saddle is not a spec that all manufacturerslist, but it matters. While the Pearl's leather upper is in itself shallow, the rails are pretty deep. Installing it in place of my Berthoud Touring saddle, my seatpost had to be lowered almost a full cm to compensate. Selle Anatomica saddles are even shallower than Berthoud, so the difference there would be greater still. I am not comfortable providing exact figures, because height is difficult to measure and I don't want to misinform. But basically it's Selle Anatomica < Berthoud Touring < Rivet Pearl, with just under 1cm of difference in height between each.

It occurs to me that the purpose of the deep rail design on the Pearl might be to avoid any chance of the leather hitting the rails should it stretch over time. There is certainly no danger of that.The wrap-around tab on the underside further reduces tension loss.

According to Debra, Rivet saddles can take about 300 miles to break in, during which time they may also stretch. The tension screw should be used to regulate tension - not just in the event of stretching, but also to find the tension that works best for the rider's anatomy.

The purpose of the slot on Rivet saddles is "to relieve pressure and help to re-distribute pressure to other areas, depending on how the rider sits on the saddle." The Rivet slot is a bit longer than the slot on the Brooks Imperial line of saddles, and considerably shorter than Selle Anatomica's.

The edges of the Pearl's sitting surface are crisply delineated, rather than rounded, which gives it a sculptural look. The "R"-embossed rivets add textural interest. The Burgundy colour, pictured here, is a deep brown with a magenta tint (and, from what I can tell, identical to Selle Anatomica's Mahogany).

For waterproofing, a chemical agent is mixed into the tanning process (a different process than what is used for vegetable tanned leather). To increase firmness and minimise sagging, a second layer of leather is laminated to the upper piece. The leather for Rivet is sourced from Wisconsin, then sent to Taiwan, where the saddles are made by a master craftsman. Rails and other frame parts are sourced from Taiwan. The saddles are assembled there and then shipped worldwide.

With the demo Pearl on my roadbike, I rode around the neighbourhood and determined that the standard (highest) tension felt pretty good. The rear felt just about right at my sitbones. The transition from rear to nose felt just a tad wider than what I normally ride. With this initial assessment I felt comfortable enough to try a long ride.




I tested the Pearl on an informal 100K. Including my ride to and from, it was an 87 mile day in the saddle. For me, the Pearl out of the box did not require a break-in period. I experienced no soreness over the course of this distance. The leather felt quite stiff, but suppler than my hard-as-a-rock Berthoud. Compared to a Selle Anatomica, the "hammocking" action was subtle, and I could not discern independent movement between the two sides separated by the slot.The curvature and surface of the Pearl's rear felt very comfortable as the miles rolled on. Once in a while I could feel the ridges of the slot toward the front. It was not enough to cause chafing in the course of the distance I did, but I wanted to note that I could feel them. What did cause chafing - and this started around mile 60 - were the sides of the saddle in that transitional part that tapers toward the nose. Given the location and nature of the chafing, this was not a breaking-in issue or a tension issue, but a structural issue - the Pearl model is slightly too wide for me in the rear-to-nose transition, which caused chafing to my inner thighs over time. Having received my feedback, Debra agrees with this diagnosis and suggests I try the narrower Independence model to compare.




Rivet Saddles

As we all know, preferences in saddle shape, size and feel are highly personal. It is always good to have options and variety. Designed by an experienced randonneuse, the saddles from Rivet Cycle Works are a welcome addition to Brooks, Berthoud and Selle Anatomica. The Pearl model is priced at $150 with cro-moly rails and $250 with titanium rails. In addition to saddles, Rivet also offers handlebar tape, mudflaps, and other goods. I wish Deb all the best with the business, as well as in her cycling adventures.
