2025 New ONIRII Triathlon TT 3D Printed Saddle ONE TT Road Time Trial Cycling Sea Carbon Fiber Ultralight t for Triathlon Bike
SaddleI noticed there wasn't a topic for this saddle yet, and I fully understand why. It is One of the most expensive AliX saddles. That said, after owning one for about 6 months, I figured it's time to share some thoughts because it's a brilliant saddle. For the sake of this short review post, I am going to compare it to three similar short saddles that I have: the Specialized SWorks Power Mimic (not 3d printed), the Fizik Vento Argo Adaptive R1, and the Syncros Belcara TT. I have other saddles, including some unpadded ones, but these are probably similar to what folks looking for a short saddle they can slam forward to get into a TT position on a road bike are looking for. The shell of this saddle is really hard, and the padding is extremely stiff. The 3D-printed padding is much firmer than that of any other saddle. The texture of the 3d printing provides a medium grip. It's about as grippy as the Fizik but less than the Syncros. Setting up the saddle, i expected it to be a bad experience. Luckily for me, the shape of this saddle really works for me. The saddle itself is flat and wide, going out to 132 mm. It's also extremely short: while it is 240mm long, the extended carbon "tail" means that it's really closer to 220mm saddle. Sort of similar to the actual seating area on a Selle SMP Well the saddle's usable sitting area ends at a taper of around 55mm. Unlike the SMP, Fizik, and Syncros saddles mentioned, it's much flatter, more like the power. However, it more or less lacks the nose of that saddle, so if you liked the Power but battled numbness even with the softer-nosed mimic, this saddle could be for you. I previously also preferred the channel approach of the Fizik Antares Vs. Evo Adaptive saddle, which this saddle also offers, creating another respite for those of us who worry about numbness on long rides. It is also worth noting that while this saddle has very long rails the actual area indicated for clamping seems to only allow you to move forward 5-8mm vs. other short saddles. So it's something, but not as much as you might think looking at a profile of the saddle. Of course, you can always try to use that extra rail. I probably will. I would love to see a V2 of this saddle with slightly softer padding and extending the clamping area enough to fully jam the saddle forward. That said, this current version is going on my gravel race rig 2026. In my opinion, if you are looking for a short saddle for a forward position and can get this one for a reasonable price, it might be worth a try.

WEST BIKING Professional Mechanic Bike Repair Stand MTB Road Bicycle Maintenance Workstand Foldable Adjustable Wash Bike Rack
ToolsThis is a great repair stand. You can't beat it for the price imo. It makes working on both sides of the bike so easy, and I really like not having to clamp the frame or seatpost. Out of the box it's only compatible with quick release bikes, but with a quick mod I can now mount thru axles. I used one of these along with a piece of masking tape to make a tight fit:

Medical FSA Approved underarm Children Thermometer, for Adults & Baby Digital Thermometer pad,Real-time monitoring APP tracking
Heart Rate MonitorsI have recently decided to try out heat training, but I wanted to avoid paying an absolute fortune for the CORE body temperature sensor. I instead decided to give this a go: It is IP22 certified against water and dust, but I can also certify it against heavy sweating, at least after a few sessions. The app that is promoted with the product requires creating an account, and for some reason syncs everything to the cloud; I instead recommend using the Tempal app. The only problem I currently have is figuring out how to securely attach it to my armpit. I am using the heart rate monitor strap for now, but it only works as long as I am not moving too much. I also just ordered an elastic hand band, which is going to take some time to arrive, but I think it should work much better. In the meantime, do you have any DIY ideas for how to attach the thermometer securely to my armpit?

WheelsI already have them installed on my bike. I removed the rim strip and installed tubeless tape. The weights shown in the photos are with tubeless tape. So far I’m very happy with them; from the little I’ve been able to test, they are very stiff wheels, with incredible lateral stiffness. I love how they respond during accelerations.

ZTTO Ultimate 11/12 Speed Road Bike Cassette Ultralight 11s 12s 11-28/30/32/34/36T Gravel Cassette 11V 12V Black Freewheel HG K7
Cassette
The reviewer analyzes the ZTTO SLR Gen 3 ultralight cassette, focusing on a specific failure case where the top two sprockets sheared off. They describe the cassette's construction: the top three sprockets are milled from a single aluminum block, with the rest being monolock steel, resulting in significant weight savings (117g vs. 260g for Shimano 105). The reviewer has personally used smaller versions (11-28T) for thousands of miles without issue but identifies a critical design flaw in larger sizes (11-30T and above). In these larger cassettes, the top two sprockets are connected to the third by a thin ring of supports, creating a potential cantilever beam effect and stress risers at sharp internal corners. This design, combined with spiky power delivery (e.g., in cyclocross) and the increased flexibility of larger sprockets, increases the risk of failure. The reviewer concludes that these cassettes prioritize minimal weight and low cost over structural safety margin and long-term durability. They advise caution, particularly for the 11-36T and 11-34T versions, and suggest stronger alternatives like ZTTO's all-steel or Gen 2 cassettes. They also note the shifting performance is decent but not as good as OEM, the cassettes are noisier, and aluminum teeth can snap if shifting under load.
AI Summary
Pros
- Incredibly lightweight (e.g., 117g for 11-28T vs. 260g for Shimano 105)
- Great looking and available in funky colors
- Low cost (about 60 quid)
+2 more
Cons
- Design flaw in larger sizes (11-30T, 11-32T, 11-34T, 11-36T): top two sprockets connected by thin supports, creating a weak point
- Risk of sprockets shearing off, as evidenced by a viewer's cassette failing after ~150km
- Sharp internal edges (90° corners) act as stress risers

Cassette
The reviewer analyzes the ZTTO SLR Gen3 11-speed cassette, focusing on a specific failure where the top two sprockets sheared off. They note the cassette is lightweight, visually appealing, and affordable. The design involves the top three sprockets milled from a single aluminum block with the rest being steel. The reviewer has used smaller versions (11-28T) for years without issue, but identifies a design flaw in larger sizes (11-30T and up) where the top two sprockets are connected by a thin ring of supports, creating a potential cantilever beam effect and stress risers. They attribute the specific failure to use on a rough cyclocross course with spiky power delivery. The reviewer concludes that these cassettes prioritize weight savings over durability and safety margin, advising caution with larger sizes.
