Just got a few bike (yay!) and installed a Zipp service course stem with Zipp XPLR 70 bars. I love that the bars can have reasonably hidden hoses and allow aero clip ons. I’m trying to find a stem that would have an opening on the bottom for the brake hoses so they can run out through the red highl…

I just ordered the FSA Energy stem for this reason. [image] FSA Energy SCR Stem At just 113g for a 100mm extension, the FSA Energy SCR Stem represents cutting edge aluminum construction. The shape is 3D forged from 2014 aluminum for great strength, with the final refinements carried out…

Interesting…thanks! I’d be curious to see your setup when you have it installed. It looks like hoses would have to fit in this small notch so I’m a little worried that could lead to kinking them :thinking: but to be fair that’s just from looking at a pic or 2 online without it in my hands to see.

If you’re going to do that… .you need to make the corners round. The 90deg corners concentrate stress.

That is a chancy modification. As mentioned the corners of the port are stress risers but aside from that cutting a large port into a structure never meant for it that is under stress in every direction is scary. I hope it serves you reliably.

[image] FrankTuna: looks like hoses would have to fit in this small notch Notch is even smaller in person - stem was delivered today. Think I might actually send it back as I’m a bit nervous for kinks also.

I was under the impression that the FSA SCR stuff was only for DI2 routing and hiding a junction box in the stem. It’s a fairly old design if memory serves. [image]
