Niner MCR Cable Routing: Refit the Pivot Before Trimming Housing
Niner MCR cable routing involves a temporary frame position that is unsuitable for deciding the final hose or housing length. The manufacturer’s routing sheet describes removing a lower linkage pivot for access, then expressly requires that pivot to be reinstalled before trimming the rear brake hose and derailleur housing. The assembly state changes the distance being measured.

Why the temporary position matters for Niner MCR cable routing
The MCR 9 RDO routing sheet says cable installation is easiest with the lower, forward linkage pivot bolt removed. It immediately warns that the distance between the front and rear triangles becomes greater in that condition. That temporary separation is an access arrangement, not the finished bicycle geometry.
The sheet also tells the installer to catch the inner alloy bearing spacers resting inside the pivot bearings when removing the bolt. These are part of the documented pivot assembly. Keep them identified rather than treating pieces released during a routing job as unrelated packing material.
Reinstall the pivot before committing to the cut
In its rear brake and rear-derailleur routing discussion, Niner repeats that the lower, forward pivot bolt must be reinstalled before the hose and housing are trimmed. Cutting to suit the temporarily separated triangles would base the final length on the wrong assembly state.
This instruction is more specific than buying a nominal length of cable housing. Supply length, access position and final installed length answer different questions. Have the mechanic plan the complete route on the identified frame and connected components before a cut makes the decision irreversible.
Finish the assembly and the control checks together
The same sheet concludes by requiring the lower pivot bolt and rear shock to be reinstalled, with bolts tightened to the applicable specifications. It also covers other control functions separately, including the remote lockout and dropper; those lines should not be confused with the rear brake or shifting route.
Tell the workshop if controls, bars or suspension components have changed. Ask for the correct frame assembly and normal operation of the finished controls to be verified before use. This routing note does not supply a universal cut length, a substitute torque specification or a hydraulic brake service procedure. The rigid RLT photograph is gravel brand context, not a picture of the MCR linkage position.
FAQ
Should the final rear hose be trimmed with that pivot removed?
No. Niner expressly requires the lower, forward pivot to be reinstalled first.
Why does removing the pivot affect the reference?
The sheet says that the distance between the front and rear triangles increases in that temporary position.
Does the sheet give one finished housing length?
No. It describes routing and assembly order; final lengths depend on the actual completed arrangement.
Keep the access position and the finished frame position separate when planning the routing appointment. The Niner topic and brand introduction provide the wider bicycle context.
