Item # ERG0050

Three sizes for every body type.

Like the range-topping road saddle from Ergon, the SR3 Pro Saddle shares the attention-to-detail expected from this German company. This means that you'll find the same respected shape, in three separate widths, as the Pro Carbon in order to ensure the long-ride support that's only achievable through an individual, personalized fit.

What's different, conversely, is hollow TiNox rails that are used in place of carbon in the Pro Carbon saddle. And, while this may add a little weight to the SR3 Pro, it still filters out smaller vibrations to help retain Ergon's overall goal of an excellent ride quality. The main culprit for those traits, however, is the ultra-thin carbon fiber shell.

At a quick glance, it's pretty obvious that the SR3 has a distinctive shape. And that's not the result of an industrial designer's assumption of what looks good. It's actually the result of extensive finite element method analysis that maps loads and areas of stress. This allowed Ergon to tune the shell construction for optimized deflection. The carbon shell is actually 3D, and it features "hollows" that provide controlled flex at the sit bones. Covering the shell are progressive dampening layers that are individual to the different saddle widths. Every size option gets its own layering for rider-specific compression. Adding to the SR3's chatter-smoothing ability, is a nose mounted micro damper.

This damper, located in between the shell and TiNox rails, filters out smaller vibrations, and it works in conjunction with the isolated rear mounting to allow the shell to float independent of the rails. The result is one of the most forgiving saddles on the market. Additionally, the rails provide 30mm of adjustment for proper fitting.

The SR3 also has an easy-to-clean synthetic leather cover — just wipe it off with a damp rag. But more important than saddle hygiene is its silicone side coating. This reduces chafing, always a good thing, and it also ensures that riders are able to effortlessly shift weight fore and aft to enhance power and comfort.

Ergon is a German company, yet instead of manufacturing the saddles itself, Ergon enlisted the help of the saddle perfectionists at Selle Italia. As a result, every SR3 is manufactured in Italy by expert craftsmen. To size yourself for an Ergon SM3 Pro Saddle, you'll need to measure the distance between your sit bones. The Small width fits sit bones 9 to 11cm apart, the Medium 11 to 13, and Large 13 to 15. This allows you to ensure proper support for not only long term comfort, but efficient and unrestricted pedaling.

The Ergon SM3 Pro Saddle is available in the colors Black and White and in the sizes Small, Medium, and Large.

  • Familiarity: I've put it through the wringer

I was looking for a mix of traditional saddle design with some new features after breaking a rail on my beloved San Marco and going thru multiple saddles from my LBS with no luck. The Ergon mounts in a flash and after 2 adjustments on the road I knew I had a winner. I've done multiple long rides (75+) and short before work speed sessions with no discomfort and no sliding around looking for the sweet spot, My fourth point of contact just stays right where it needs to be and lets me put power to the pedals. I went to the website and put in my measurements and ordered a small ( I'm 72", 175 lbs, 32 inch waist). I highly recommend this product.

I too own and love this saddle. Just a quick point: make sure you measure your sit bones to determine your correct size - its much more important than height weight and waist size.
