fi’zi:k Tundra Saddle Review

Pro Reviews Saddles

Reviewed by Brian Mullin aka Gram and Pastajet

I have been out testing the new fi’zi:k Tundra for a couple of months now, and for a cross-country saddle I have been very impressed. It is not going to win any awards for the most comfy saddle in the world, but it is a specialty beast, and it competes well within its realm. It seems that the road-specific fi’zi:k Arione saddle has been tweaked as an off-road saddle, creating a minimalist cross-country saddle meant for the racer, cross-country rider and weight weenie.

Per fi’zi:k, the company was “Born in 1996 as a brand made for high performance, fi’zi:k was designed in the USA, and handmade in Italy by the world’s largest saddle manufacturer, Selle Royal. Fi’zi:k is the phonetic spelling of the word physique, referring to the form or state of the human body.”

The new Tundra is fi’zi:k’s lightest mountain bike saddle, and it comes in 2 versions, the Carbon braided railed version in white (which I tested), and the K:ium railed (a Titanium alloy) version in black. My test Carbon version weighed in at 209.8g (2 grams less if you take off the ICS fi’zi:k logo insert), and it is supposed to weigh around 20-40g less than the version?

The Carbon braided rails are not round, but have a fat ovaloid shape (7×9 mm), so it might not fit all seatpost clamps. The carbon rails are wrapped with another layer of carbon fiber cloth, so they have a grabby feel to them, so when it fits into a seatpost and is clamped down, it stays put, which is a very nice feature. The carbon fiber cloth is also supposed to reduce any damage to the carbon rails.

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

    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.

    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.

    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!

    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?

    Wonderful review as usual Brian!

    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.

    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.

    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.”

    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.

    Fair e’nough.

    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

    WTB Rocket V SLT 210g, and comfortable to boot 🙂

    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.

    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?

    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.
