Carbon vs. Leather: C Series and X Series Compared

We get a lot of questions about how C Series compares to leather. It really doesn't.

C Series is a tighter, less compliant, all around more energy efficient riding surface. If you've spent every last dollar making your bike lighter but your butt still hurts, C Series is for you. If you charge up hills with reckless abandon, and enjoy a stiffer riding platform with just the right amount of give to keep you comfortable that prioritizes speed and performance, C Series is for you. Almost no energy is lost due to the Flex-fly inverted wings moving under your sit bones and the Leaf Spring frame keeping your butt pinned to your bike. What energy is lost, is lost in the name of less sit bone pain and bruising. Efficiency is the goal.

X Series is a touring saddle. Soft, compliant, supple. The goal isn't to get you through the next 100 miles without pain. The goal is to get you through the next thousand. The goal is to get you from Alaska to South America without a second thought for your butt on day 30. Weight is not the focus. Long distance comfort is the focus.

Carbon Saddle Update Nov 2016

The final 94 carbon saddles from the Crowdfund will ship on Monday, Nov 28, 2016!  They are completely assembled, the epoxy is drying over the weekend.  We are so grateful for your participation and your patience as we moved through the development and production process.

Mostly the saddle has had great reviews, especially for climbers and high impact riders.  For those few expecting a leather saddle in carbon,'s not the same, but it's great!

Happy Thanksgiving

Carbon Rails and Seat Clamps

Non-carbon saddles are typically made with round 7mm rails that fit all standard seat post clamps.  Carbon saddles however, are made with an oval rail that measures 7mm wide X 9 mm tall.  You will need to purchase a seat post clam that accommodates this 7X9 configuration for your carbon saddle.

There are two different types of seat post clamps that will work.

The first is a clamp that affixes to the top and bottom of the rail, rather than side to side onto the rail.  This clamp, which comes standard on many newer bikes, fits both round and oval saddle rails.

The second clamp that will work is a side to side clamp that measures 7mm wide X 9mm tall. 

Please make sure to procure one of these types of seat post clamps before you receive your saddle.  A traditional side to side 7mm clamp will not work on carbon rails.

For Women Only

We are often asked if we have a "Women Specific" model.  Our saddle works equally well for women and men with regard to sit bone issues.  But there is a caveat for some women with regard to the front of our slot.

Caveat - female riders sometimes find their lady parts and the front slot aren't well suited to each other.  For women, soft tissue must fit inside the edges of the front of the slot.  If this doesn't happen naturally, accommodation must be made for these women by widening the slot a bit. This is done with a sharp knife, a dremel or a large rounded file.  It also makes sense to bevel the 90 degree edges of the slot at the same time.

Call Carol at 619.269.1120 ext 102 for further discussion of this issue if you have questions or need further clarification.

Leather Types

We use two different types of leather in our saddles - WaterShed and TruLeather.  The finished top surface of WaterShed leather will repel moisture, TruLeather has no water resistant qualities and must be waterproofed.

All saddles come from our factory waterproofed on the bottom with our Saddle Sauce.  We recommend anyone living in a humid climate (FL, GA, NC, SC, AL) apply Saddle Sauce to the raw edges of all our saddles and to the top of any TruLeather saddle.  Waterproofing is essential before riding in any kind of wet weather.  Never use any waterproofing product that contains silicone or solvents nor Brooks Proofide, as it's purpose is to soften the leather.  Beeswax products are fine.

Leather cannot get soaking wet.  It will lose it's form and stretch out.  Be sure to take along a rain cover or grocery bag to keep your saddle dry in a downpour.  And remember, water typically comes up from the road off your tires during a rainstorm.

In our store we've designated:

  • WaterShed as WS
  • TruLeather as TL

General Information ›   Rails ›  


I’ve heard your rails bend.  Is that true?

It is true that under certain circumstances the Selle Anatomica rails are prone to bending.  This is primarily due to the following:

  • Our fore/aft rail adjustment is MUCH longer than any other rail in the marketplace.
  • When riders stay seated over bumps and come down with more than 450 pounds of pressure on the seat, that pressure can bend or break our rails.

Our warranty replacements are less than 1% of our annual sales.  Although this is something written about in the popular blogs, it is not a big problem.

What are your rails made of?

Our rails are made from Chromoly 4130 Steel.

Do you warrant bent rails?

Yes, within the first 12 months after purchase we will replace a bent or broken rail set.  We do not pay for shipping however.

What can I do to make sure my rails don’t bend?

  • It is always wise to lift your weight off the saddle when going over bumps.
  • Do not use a setback seatpost with more than 20 degrees of setback
  • Never set the saddle all the way back on the rails. Leave at least ¾ inch of rail in front of the seatpost clamp.
  • Use a seatpost with a 1½ inch (38mm) or longer clamp on the rails. Small, individual attachment points at 1 inch (25mm) or less put too much pressure on our rails..

General Information ›   Rain ›   Stretch ›   Tension ›  

Water and Leather... not mix well.  Water saturation makes leather stretch.  Carry a grocery bag or saddle cover with you at all times to cover your saddle if you encounter serious rain.

WaterShed doesn't mean waterproof. The top of our WaterShed saddles repel water because of a special and expensive additive in the tanning mixture. Our bottom pieces of leather however, are veg, a type of leather that has no water repellent properties. We coat the bottom of the saddles at the factory with Saddle Sauce. However, if you get the bottom of the saddle wet, there is a chance water will seep in at the edges and the leather will stretch. We do not warrant leather failure due to excessive exposure to water.

If your saddle gets wet, loosen the bolt, remove all tension from the leather and let it dry naturally.

Tension Adjustments

Is my new Selle Anatomica saddle already tensioned?

As part of the manufacturing process, after we attach the frame to the leather we adjust the tension on the saddle.  So, it should arrive in your mailbox pre-tensioned to the correct tension.  But, if it arrives and the tension bolt is loose, go ahead and tighten it a couple turns.

How often should I re-tension my saddle?

Every piece of leather and every rider are a little different.  But, generally speaking the leather we are getting today requires tensioning in the first rides you will take.  So, be sure to carry a 6mm allen key with you on your ride.

How do I know how tight the tension should be?

Put your hand LIGHTLY on the top of the slot – putting no pressure on the leather.  Turn the allen key counter clockwise (to the left) until you feel the leather begin to stretch.  Take a look at the narrowest part of the slot.  It should be about ¼ inch or 6-7mm wide. If repeated tensioning does not open the slot to the recommended width, shaving the slot open at the closest point in the rear is within the guidelines of our warranty.

Your saddle should also take on a hammocky appearance as it breaks in and becomes acclimated to your body.  Looking at it from the side, it should have a definite dip.  If it appears straight across, it’s too tight.  The narrowest part of the saddle should not be more than about ¼ inch or 6-7mm wide.

What happens when my leather can’t be tensioned any more, when the bolt is fully extended?

When your leather is worn out, you can send your old saddle to us for a NewSkin.


Does my new Selle Anatomica saddle require Waterproofing?

All leather saddles require waterproofing if they are ridden in wet, damp or humid weather.

 Does SA waterproof the saddles?

We do apply Saddle Sauce, the Selle Anatomica brand of waterproofing, to the underside of the leather at the factory.  However, we recommend reapplying Saddle Sauce to both the bottom and the raw edges of the saddle before riding in damp, wet or humid weather.

 How does my saddle get wet?

When you are riding in the rain, with your butt in the seat, it is primarily the bottoms of the saddle that get wet – even if you have fenders.   Why?  Because your butt is covering the top of the seat and the water splashes up from your rotating wheels onto the underside of the saddle.

 What kind of waterproofing should I use?

Saddle Sauce is an acrylic based formula that sits on top of the leather and prevents moisture from entering by creating a barrier.  It does wear off, particularly where there is frequent rubbing on the saddle and must be reapplied at periodic intervals depending upon how much you ride, and how wet your climate is.  Apply a thin layer, especially to the bottom and the raw leather edges, wipe off any excess with a soft, wet cloth and allow to dry at least 4 hours.

Do not use Proofide as it softens the leather.  Do not use any waterproofing product that contains silicone or solvents intended to "condition" the leather. 

 How often should I waterproof my saddle?

For all SA saddles, waterproof the bottom and the raw leather edges prior to riding in any kind of wet weather or if you live in a hot and humid climate. Along with your sweat, water can also be absorbed out of the air and can sometimes cause the leather to stretch if it’s very hot and humid.

TruLeather should be entirely waterproofed any time after it is delivered to you.  Do not waterproof the top of a WaterShed leather until the leather is broken in and stretched out a bit. 

 What is the difference between WaterShed and TruLeather?

No leather is water proof.  Nor can any leather saddle get soaking wet.  But, our WaterShed leather is water resistant (on the top of the leather only) due to an additive in the tanning process.  Water beads up and bounces off the top of the leather.  TruLeather is not water resistant.  It must be waterproofed.

 How do I tell if my saddle is WaterShed or TruLeather?

Turn it over and look at the first 4 digits of the serial number.  Any Serial Number containing WS, WC or W is Watershed.  Any Serial Number containing TL is TruLeather.

 What are the layers of my saddle?

A Selle Anatomica saddle has two layers – the full grain, color tanned leather on top.  On the bottom, a top grain, uncolored leather we call the laminate.  The bottom laminate and raw leather edges of all SA saddles require waterproofing.  The thickness of the laminate support layer on the bottom is the difference between the X and T Series.  The X Series is thicker than the T Series.

 Can I leave my saddle out in the weather?

If your bike must remain outside, we recommend a rain cover.  In the absence of a rain cover a shower cap or plastic grocery store bag will do just fine.  Cold weather will not damage your leather, but the saddle should not be left out uncovered in any kind of rain.

Slotted Saddles

There are lots of leather saddles with slots these days. We like to think we started a trend. Imitation is the sincerest form of flattery, right? The difference is that we don’t soak and bake our leather. It is soft to begin with so you don’t have to spend time and money making it soft. We also have the only functional slot on the market. The back third of our slot is where most of the magic happens and is what every other slotted leather saddle lacks. As you pedal and your sit bones move up and down, the leather moves up and down with you. We patented that so the others guys can’t do it.

Most leather saddles, other than those British guys who make a truly excellent product and for whom we have a great deal of respect, are made in Taiwan by a company who got their start making furniture. We make our saddles in the heart of America. We employ American workers and take great pains to do our business and spend our money here in the US. It isn’t always the easiest way to get things done, but we believe it is the right thing to do.
