Hylix is a Chinese brand that offers affordable bicycle and mountain bike parts. The selection isn’t limited to just stems, but they also offer handlebars, seat posts, forks, rims, for example. Most of their products are made out of lightweight materials, such as Carbon Fiber or Aluminum. This helps to make their products stand from the crowd by being lighter than other products in the price range. However, there’s more to a good product than just light weight, so let’s dig further.
Hylix stems seem to be aimed more towards the Cross Country crowds since the stems tend to be available in only 80-110 mm lengths depending on the place of purchase. A Carbon Fiber version is available as well, although it weighs more than the aluminum stems. Besides, cheap Carbon products can be quite sketchy when it comes to quality.
At first glance and weights
Both Hylix stems arrived wrapped in bubble wrap, with just a thin plastic bag around them. At first glance, the quality seems to be okay at best. While overall both stems felt solid and didn’t seem to have any visual structural flaws in them, the finishing left a lot to be desired. Especially the decals look horrible and are off-centered. Out of the two, the almost fully shiny black model looks way better, and a lot less stereotypical “made in China” -like. If looks are everything to you, then these products are not best suited for you.
For the price, both stems are very lightweight. The 80 mm, 17-degree stem comes in at just 114 grams whereas the 90 mm, 6-degree stem with titanium bolts is only 100 grams. Even the version with titanium bolts is still less than 25€, quite impressive!
As with all cheap Chinese products, the threads are often the weakest point. No wonder it was a bit unnerving to fully tighten the handlebar clamp and the stem to the steerer tube. Neither stem has any sort of torque specification markings, which tells a lot about quality. I ended up starting from 3 Nm of torque for all bolts but upped to 4 Nm later on. Never had any issues with the bar or stem slipping, but in case you do, I guess it’s worth trying to go up to 5 Nm. There’s no guarantee that the threads/bolts can handle that though.
Hylix Stems Tested
I had the 80 mm Hylix stem with steel bolts installed for over three months before switching to the 90 mm Hylix stem. During those months it saw lots of crashes, hard riding, and tons of adjusting when I was trying to get the handlebar setup right. Despite the horrible decals and the threads feeling a bit sketchy, it never caused me any trouble. For the 15€ I paid for it, the stem was a bargain.
I can’t say much about the 90 mm Hylix stem with titanium bolts just yet. I only got it recently, so I haven’t had enough time to test it thoroughly. So far it seems to be holding up well, but time will tell.
For the price, Hylix stems are great for someone looking for a lightweight stem. The finishing won’t be as nice as on the more expensive products, but in our testing, the stems have held up well and haven’t caused any issues so far. I can totally recommend them.
- Light weight
- Finishing is not the greatest
- Like other cheap Chinese made products, quality can be a hit or miss
