That’s great with my new handle bar spring velobike to

Love it

Long, stiff. The integration with the Argon18 Pro TKO is great, and now with the Altias bars. Outside of getting me in a more comfortable and aero position, is just finished the look of the bike nicely.

It makes my TKO look amazing and fast. The user manual was very helpful to order the perfect length and stack. Don’t forget to order the correct bolts for your setup.

The stem perfectly fits and looks great in my Argon 18, you feel like more aero and more faster.

I was impressed when I installed this stem. The handlebar area became 200g lighter, and both aerodynamics and rigidity improved. There was no flex at the start of sprint. It is expensive, but it's worth buying.

Super stiff and gets my position legal. Looks Great aswell!

If only Argon 18 could partner with Velobike and make these an OEM option… every Argon18 owner should be using this stem. It’s so stiff, strong and confidence inspiring. Velobike thank you!

Perfect system

Once you use this, you won't be able to let it go

ステアラーモジュールを抜いて直接フレームに留める形になるので、単純に剛性感がアップします。短距離のスタートだけでなく、中長距離のダッシュに関しても反応が早くなるので、ポジションを決めるのがシビアですが、きちんとしたサイズを買えば必ず機材のレベル、空力共に向上すると感じました。

Beautiful stem and completes really nice smooth lines to the frame

Stiff and light stem, perfect upgrade.

The best stem you can have on your argon 18 track bike and also saves time and is so easy to install, just amazing!!

I've wanted a stem like this for a long time. The previous options were just too expensive - I did consult with a local machine shop to make one too. Anyway, I'm super excited to have this. It just looks so smooth and sleek. It fits nicely. And I no longer have to remove/attach the stem mount when swapping to pursuit bars. (This was a minor inconvenience, but it was annoying, and it provided too many opportunities to lose pieces in travel.)

I bought a 130mm by 60 rise altias stem for my Argon. Works perfectly and saves me heaps of time switching to pursuit setup. And looks as flash as Michael Jackson.
