Triathlon bike saddles: 9 of the best reviewed

A sore backside can wreck your race, so it's crucial you choose the right saddle. We test 9 of the best to discover which brands know how to make a good perch

After spending a small fortune on your dream machine, it can be all too tempting to stick with the stock saddle that comes with the bike without as much as taking a test ride. But your saddle choice is one of the most crucial elements of your ride. There are only three contact points between you and the bike: your feet, hands and, of course, your gluteus maximus, the latter being the largest part and where you generate the most power from.

Explained: ITU vs. UCI saddle positioning

How to choose the right triathlon bike saddle

 Triathlon bikes buyer’s guide


A slight shift in your optimum position, particularly over a long-course tri, and some of that power could be lost; and if you stick with an uncomfortable position out of grit and determination, this can lead to numbness and painful saddle sores.

It might seem that a hefty saddle with plenty of gel in the nose might serve you best for longer distances, but this is at odds with the latest tri/TT-specific saddle designs, as it’s the density of the padding, not the size, that makes it comfortable.

Firm padding is less likely to deform over time so, while it might seem uncomfortable, your sit bones will thank you for the pressure relief.

Of course, saddle choice is incredibly personal, so the highest marks here have been awarded to saddles that we think will work best for the greatest number of riders, feature the greatest innovation and material construction, and are at a price that represents value for money.

Pro Aerofuel


Coming with standard 7mm round stainless rails, a fair amount of clearance and a cut-out, the 191g Pro Aerofuel is the easiest of the saddles to install. The perch is designed to encourage an aggressive and aerodynamic position. The stiff carbon-reinforced base is short and there is additional EVA padding at the nose – measuring 40mm the nose is fairly wide. The anatomic recess and cut-out aim to improve blood flow and to reduce discomfort and the saddle’s flat side-on profile meant, in addition to a full-on tri set-up, it didn’t feel out of place on a road bike or when being ridden in a more upright position. To promote a stable riding position the saddle’s cover has anti-slip strips, but the upper of the Fizik Mistica is far more effective. The Aerofuel is a sleek-looking seat, although a hook at the rear for racking, or the option for a rear bottle cage for Ironman, would be advantageous.

Verdict: we’d like more tri-specifity, but an impressive saddle at a decent price 80%

BioFlex on GEL Ozone Sport 


This budget saddle is a beast compared to anything else on test, at a whopping 446g. It lacks any tri add-ons but then, at £30, we wouldn’t expect them. It mimics some of the features of far more expensive saddles here, such as a pressure relief channel, but the padding surrounding it isn’t very firm at all and it’s a very wide platform, which is plush for short rides but will position your legs too far apart for extended faster efforts in a TT position. If you’re looking to tackle your first tri or sportive and want something relaxed and extremely well-padded, this will do the job. But if you’re racing for any length of time and putting serious miles in, then that squidgy padding is likely to lose its shape. 

Verdict: Heavily padded but will appeal to beginners 68%

Buy from

Selle San Marco FX


The Shortfit Carbon FX Wide is Selle San Marco’s latest ergonomic style of saddle, which means a short nose and a large cut-out. The wide and sloping rear of the saddle offers ample support, while the large cut-out aims to prevent numbness. The seat has a noticeable ‘wave’ side-on profile, with a central depression in excess of 5mm, which is intended to aide pelvic rotation and will appeal to riders that prefer a fixed, or have a more relaxed, riding position.

Thanks to pairing a carbon reinforced base with oval carbon rails, the Carbon FX is the lightest saddle on test at 140g. And yet, despite the substantial cut-out, the oval rails and the saddle’s low profile make installation a little more challenging. Although not as multisport-focused as the Mistica, the Carbon FX allows a forward riding position as well as being suitable for longer, relaxed days in the saddle.

Verdict: a Light, short-nosed and versatile saddle with carbon rails 75%

it looks like there's been a massive development since 2013-14 as i cannot see any Koobi saddles here originally praised and reviewed all over the place.

i guess i know why now

no bitterness, no pretends, this is just a reflection over a couple of mistakes i made recently and a piece of good advice that might help you to avoid this far from marvellous product

I have owned this saddle for several months now which is pretty much how long it has been taking me to readjust to this saddle. i am not sure how anyone can see it as a comfortable mid range mileage saddle of a good value.

I have bought this saddle, following a lengthy research and various recommendations of people i considered experts in their field including fellow cyclists and triathletes.
to my great surprise and dismay what arrived was far from the superior light-weight split nose saddle i was convinced i had bought.
perhaps the most obvious are the bizarre sides near the sit bones area made of black textile - allegedly kevlar?tha is hard to believe as they are not durable as expected !? (the black part on the side - the photo on the internet does not provide a detail - for a good reason i guess) most ridiculous - why would I want the sides of my saddle made of significantly less durable material than the rest. to save a couple of grams? i can only hope now that i will remember not to lean my bike against a wall or anything ever again to avoid damage of these fragile ‘patches’. Having examined this thoroughly i can see clearly now how the stitches are unevenly tightened as if someone was trying to stitch it on the hard support part. i can definitely feel the seams border lines after about twenty minutes. takes some getting used to and thus I do not consider it a sleek design at all.

I am not expecting this saddle to last more than one season. the stitching is already showing a sign of strain and wear.

just one more thing -
I have stuff shipped from the US to the UK regularly and it seems a very common practice of the senders/internet sellers to declare much lower value of the items shipped on the label/declaration sticker than is the actual price of the items - it often prevents customs from snooping around and damaging parcels which are then inadequatly re-taped, it saves customers a lot on import duty and tax, which is ok with most of us.
i am not quite sure what koobi was thinking declaring higher price of the saddle on the label than what i actually paid as this resulted in Customs demanding a hefty import duty, without them even opening the package as the label was so carefully filled out!


the model in question to avoid is Enduro Au
