Hidden cables with choicer of H-bars!

Using this with a Ritte Esprit with fully integrated cables. As long as your frame manufacturer makes an adapter/headset cover for FSA ACR spacers, this stem will work perfectly to let you run internal routed cables from the frame to a fully internal routed bar or like I have on my bike, an externally routed bar, but with the cables covered and tidy right up to the bars. Also allows a pass through steerer (unlike some of the other ACR stems) so you can stack extra spacers on top until you have your final fit and steerer length dialed, then cut to length.

Full/Semi Internal Masterclass
- Familiarity:
- I've put it through the wringer
I’ve got this on my gravel bike that uses the ACR internal routing system. As far as non-proprietary internal routing systems go (you find the ACR system on several different brands of bikes), I think ACR is the most refined and easiest to work with. This is my preferred stem to use with the ACR system, because you can run the cables neatly out of the head tube and under the stem with the included adapter, or you can route them fully internally through the stem and into the bar using the appropriate adapter, which is also included. The stem comes with two 10mm and two 5mm spacers that split for easy addition/removal, and works great for gravel or road bikes with an ACR headset. This option is a native standard 1 1/8” steerer clamp diameter, and the non-ACR version we carry is a 1 1/4” clamp for some Canyon, Giant bikes.
