I’m 99% sure he is actually just clamping the seatpost way below the minimum insertion. But, the seatpost I have, only has 240 mm maximum extension? So, Trace Velo either has a longer seatpost, or, he has his seatpost set up 45 mm BEYOND the minimum insertion line (measured from two different videos): Using that measurement, and a photo of his bike setup, you can measure his seat post extension at 280-285 mm in the below photo.

Then I realised that the Trace Velo guy looks quite tall – So I went to his build video and he says he ordered the size 58, which has 522 mm seat tube length (C-T). These are some of the pictures I made for them to explain the issue: I sent them dozens of photos and tried to explain the issue several times over the course of a week. To be honest, I don’t see how anyone my height or taller could possibly fit on this frame, or the size 56 or 58, with the tiny seatpost. I asked several times if there was a longer seatpost for larger sizes, they said no. I tried to explain all this to the Trifox support guy, but they don’t seem to understand my issue (or don’t want to). The frame is the right size for me in reach/stack/etc., the seat post is just extremely short. You might think I just need the next size up, but the size 56 only has 20 mm more seat tube length, and 20 mm more still isn’t enough, and the 56 has too much reach for me anyway (I’d need a tiny stem). The seat tube on the Trifox is actually 5 mm taller than the TCR, but the distance from saddle rail to min-insert line on the Trifox seatpost is just 240 mm, 60 mm shorter than the TCR seatpost! Basically, I need the seatpost to be at least 30 mm longer (40 mm really, to be safe with different saddles and pedals). On the Trifox X16, the maximum distance from the BB to the saddle rail is just 720 mm, so the saddle at maximum height is 30 mm too low for me. The maximum distance from BB to saddle rail on my TCR is about 780 mm, and I have it around 745 mm (depends on saddle and pedal stack, obviously). It was only after assembling the bike that I realized that there was a major issue: I have normal length legs for my height (inseam 83 cm), and on my TCR, the seatpost is about 20 mm from maximum height/minimum insertion. The geometry chart is only 1-2 mm different at most, basically identical. I compared the geometry to their geo chart, and bought a Trifox X16 size 54. I’m 178 cm tall and I ride a Medium Giant TCR Advanced (2016). Its build quality is great, so you can rely on it and feel safe when riding it.I bought this frame after seeing Trace Velo, Hambini and Oz Cycle give great reviews for Trifox frames. I believe it delivers great value for the money. Is there anything you don’t like about this bike? I was very surprised by the quality of the finish done and its low weight. What are your overall impressions from riding Trifox X10? What surprised you the most about this frameset? It shakes slightly when entering/exiting a draft, but all bikes I’ve ridden were like that. Yes! It’s very stable and gains speed very quickly. Is the bike stable at high speeds, especially in descents? Unfortunately, local roads are not very good. What about the riding comfort? Could you rate it on a scale of 1-10? How do the frame and wheels handle harsh roads?īecause of its relatively aggressive geometry, I experience hand numbness during long rides (around 150 km). Feel sluggish? No! It’s very responsive.Īero bikes are known for their high stiffness. Does it feel and ride like a proper aero road bike? Or does it feel sluggish?īecause it is an aero bike, it is fast on flats, in descents, etc. The front view of the Trifox X10 Trifox X10 handlebar Front brake detail Rear brake detail Trifox X10 seatpost with the Selle Italia saddle Trifox X10 seatpost Trifox X10 Riding Experienceīelow, you will learn more about Gean’s riding experience with Trifox X10. Because I am a bike mechanic, I didn’t experience any issues when building the bike.

No! By the time the frame arrived, I had researched all the parts needed. (Note: Gean ordered the frame from Aliexpress Brazil.)ĭid you experience any issues when building the X10 bike (especially with the bottom bracket area and internal cable routing)? I received the frame in less than 5 days.

They answered all my questions, and everything went normal.

I ordered the frame from the Trifox official store on Aliexpress. Where did you order the frame? How was the purchase? Did everything go smoothly? Additionally, their affordable prices, and I liked this frame model very much. I decided on Trifox because, during my research, I didn’t find any complaints about them. Gean, can you please explain why you decided to buy Trifox X10? What was its main selling point for you? So, I asked him a few questions regarding the pre-order and build process.
