Just received C64 disc with internal routings along with an alloy SR9 stem. I was expecting the R41 carbon stem with internal routings. Supposedly, Colnago had issues with manufacturor of carbon stem with internal routings and ending up with the alloy SR9 stem. It’s not great looking and kind of clunky and I wanted carbon. Does anybody know if I have any other options for a carbon stem with internal routings that might work. Thanks.

Hmmm... did you get the fork with the notch down it’s steertube? Haven’t seen one of those in the whole either.

I’m not sure. I left frame with LBS waiting for groupset etc. I will have LBS take photo tomorrow to send to me.

FWIW, it looks like the Gold Private Ed. C64 disc on the Colnago website has the alloy SR9 stem.

Did you not have to order the R41 stem seperately?

LBS thought they ordered the R41 and the SR9 showed up 2 days ago.

Here’s a photo of the SR9 stem on a bike

I don’t know what the “SR9” is but that looks like a Deda Superzero stem without the logos.

Now that I see it on a C64 it doesn’t look that bad, but my primary concern is that usually alloy stems transmit a lot more road buzz than a carbon stem. Don’t know if will work but the FSA Vision Metron 5d looks pretty nice—at least on a Bianchi Xr4.

All internally routed c64 disc framesets come with the D-shaped steerer tube to accommodate cable routing. The stem furnished with the frame works just like those found in the BMC teammachines.

You have to be careful to find a stem that will give room for cables to run in the front. I recall manufacturers having different setups for the proprietary stems (some running down the middle and back. I know shimano had one that permitted cabling to go directly through the center of their hollow carbon stem. That may also require their handlebar.

I had the FSA Vision Metron 5d on my Bianchi Xr4. There was a dedicated space in the stem to hide the junction box, but there was no internal routing for hydraulic cables. Bianchi uses a new metron for their xr4 disc but the internal routing may go through the rear of the stem rather than the front. More importantly, the rounded swooping aesthetic doesn’t flow well on the colnago frame. Does the alanera have internal routing?

I’m going to use the colnago stem as it resembles the deda superzero. If an alternative becomes available I’ll pick it up at a later date.

Thanks. After looking at options, I think that I'm just going to stick with the alloy SR9. The fewer the issues the better. And, I will be on look out for a carbon replacement along with maybe doing the EPS 12 speed conversion if there is a way or option to hide interface module.

Yes, LBS sent me a movie that shows the notch. May try to post some photos from the video later.
