fi’zi:k Tundra Saddle Review

Pro Reviews Saddles

The saddle is covered in Microtex, which is a synthetic leather, and has 3 sides that have an internal carbon framing. The framing wraps around from the rear sides to the front and helps to protect the material edges. The material has held up well, and has survived a couple of good crashes, in which my body suffered a lot more damage than the saddle, thank goodness for my Chiropractor. The Microtex material does not fade, and is water resistant, which was noticeable when I didn’t get a wet butt after the bike got soaked in a rainstorm.

The saddle has 2 sections of the material, a shiny slightly stickier/tackier section that runs along the center of the saddle (more pronounced on the nose), and then a normal section running along the edges and the wings. This differential allows you to move easily around the saddle, but gives you some added traction/grip when either climbing or putting the pedal to the metal.

The saddle has a carbon reinforced nylon shell and is 290mm long and 125mm wide, while the nose is 40mm in width. It has a flat top with the rear sides drooping off in the typical Fi’zi:k wing fashion, and it is sort of shaped like a Mandolin. The nose is slightly squared and nice and wide, so it is a great place to roll up onto for those tough steep climbs, although it could use a more padding since it is a bit too hard.

When I was playing around with the saddle, a small plastic fi’zi:k logo on the bottom of the saddle seemed a bit loose to me. I then realized the logo fit into a small plastic receptacle under the saddle shell and was the spot for the Integrated Clip System (ICS), where you can directly connect a fi’zi:k rear light or a saddle bag without the need for straps. The ICS is a very nifty idea, and what a great place to incorporate something in a usually unused space. I tested out the fi’zi:k Blin:k rear light, which popped into the ICS slot easily. The rear light uses two LED’s and has a switch on the back (the light itself) that allows you to choose either a constant mode, a blinking mode or off. With the long summer hours, I didn’t really get to test it out, but it will be a nice addition for Fall, Winter and Springs rides in the dark. I always ride singletrack trails at dusk with front lights, so it will be nice to have a light on the rear, mostly to alert chasing bears to keep their distance. I did not get to test the fi’zi:k Saddle Pa:k, which comes in 2 sizes, a medium and a small.

    Well, I wouldn’t call it a WW saddle. It’s heavy? WW saddles are like 100g. (ish)

  • Anonymous says:

    The average weight weenie saddle weighs around 160g, yes there are some that weigh less, but a lot of those have given me short term nerve damage, so call the Tundra an overweight weight weenie saddle if you like! Trust me, I have tested and reviewed my share of WW saddles. The Tundra is a cross country race saddle that will appeal to a WW.

  • Andreas says:

    It could very well appeal to some WW’s, but it’s still not light. Maybe very good, but not WW light. Not even close.
    Tune Speedneedle Marathon weighs just around 107g. and ít’s reasonably comfy = WW saddle. Becker mtb approx 60g., not very comfy and not padded. But it’s a true WW saddle.

  • Brian Mullin says:

    The Becker can be comfy if it fits your butt, the Speedneedle gave me numb legs (i.e. nerve issues) so it sits on the shelf at home, much like many of my WW saddles. The average normal saddle weighs around 300 grams (or more) for comparison, again this is a cross country race saddle that will appeal to a weight weenie person or someone looking forward to lighten their bike. My job as a reviewer is to look at this saddle in relation to a lot of criteria, and although might be considered a pig dog heavy weight saddle to the weight weenie aficionado, it is a fairly lightweight and decently comfy saddle. I have been a weight weenie myself for over 2 decades, so I always feel the tug!


  • Andreas says:

    I guess there’s a big difference in what difines a WW, from Danish cyclingculture to the American then. In Denmark a 200g. saddle is no way near beeing a WW product.

    How do you define a WW?

  • Francois says:

    Wonderful review as usual Brian!

  • hardmtnbiker says:

    200g is light for an MTB XC saddle. Maybe for the hardcore racer it’s heavy and most them use road saddles anyway. If your racing out of the saddle for most of the race then comfort is not an issue. Everyday trail MTB riders that like to keep their rig light and add bling will like this saddle. I think it looks nice but still like to have kevlar edges on my saddles for durability.

  • Andreas says:

    That makes more sense, but I just wouldn’t call “Everyday trail MTB riders that like to keep their rig light” WWs.
    Well it’s a cuestion of what you put into the words WW and personal preference.

  • Brian Mullin says:

    Your point has been made, lets not continue with this thread, please. Like my review states “fi’zi:k’s has another winner with the Tundra Carbon in the cross country racing and weight weenie category, although it is a tad heavy for the weight weenie guru.”

    Brian “Gram” Mullin

    weight weenie

    1. (slang) A cyclist that is concerned about the weight of his/her bicycle.

    weight weenie

    Bicycle enthusiast who becomes obsessed with subtracting weight from his bicycle at all costs, including overriding safety concerns and practicality. A Weight Weenie will always replace a 100 gram component with a 99 gram component regardless of all other factors, including cost, durability, and overall design and functionality. Materials that are commonly used in the pursuit of lightness include: aluminum, carbon fiber, composites, and titanium.

  • Andreas says:

    Fair e’nough.

  • Thor says:

    Ha! No way a WW saddle… 200 gram, you must be crazy if you call that for a WW.

    If you are a real WW, you don’t fucking care about the comfort

  • Anonymous says:

    WTB Rocket V SLT 210g, and comfortable to boot :)

  • Indiefab says:

    My OEM-takeoff WTB Silverado with Ti rails is just under 200g, cost me $60 and is comfortable as a leather couch. I’d like to try the Tundra, but don’t plan on switching.

    Except when the aforementioned nerve issues kick in, I guess.

  • dingo says:

    Top review. It draws attention to the considerations needed when making a purchase so i’m better armed when i walk into the shop.

    One question tho. I note the stitching seems to be pulling in the photo of the saddle rear. Is that normal?



  • pastajet says:

    The picture just make sit look that way, the stitching is fine, they use some large thread also so it makes it stand out a bit more.
