Beta Bottle Carrier (45/63) Installation Guide

Pre Step — Verify Compatibility

Confirm your seat post set up:

  • 10 mm Ritchey thru-rails present → Carrier can mount directly

  • Standard saddle rails → Beta Saddle Bracket required (see Beta Saddle Bracket Install Guide).

⚠️ Bikes without 10 mm thru-rails cannot mount the carrier directly.

Step 1 — Position the Carrier

  • The carrier comes with a 10mm diameter rod --> Attach the rod to the carrier 

  • Adjust the length of the titanium rod to desired length

Step 3 — Install Mounting Hardware

  1. Insert the two M5 button head screws through the carrier mounting holes (as shown by blue arrows)

  2. Thread screws by hand first to avoid cross-threading

  3. Tighten both screws evenly

Step 4 — Torque to Specification

  • Torque each M5 button head screw to 4–5 Nm

📌 Use a calibrated torque wrench. Do not exceed recommended torque.

Step 5 — Install Bottle Cages

  • Using the threaded holes on the carrier - install your bottle cages 

  • There are three different boss configurations 

  • Can mount two bottles side-by-side (bottles will be vertical) 

  • Recommended to use two Kappa Saddle Cages
