Beta One 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
⚠️ Bikes without 10 mm thru-rails cannot mount the carrier directly.
Step 1 — Attach the Carrier
If your bike has 10 mm thru-rails 👇:
-
Position the rod at the seatpost mounting interface.
-
Secure using two M5 button head screws.
-
Tighten evenly (final torque applied after alignment).
If using the Beta Saddle Bracket 👇:
-
Install the Beta Saddle Bracket first (see Beta Saddle Bracket installation guide).
-
Attach the rod to the bracket using two M5 button head screws.
-
Tighten evenly (final torque applied after alignment).
Adjustment:
- Set the desired fore/aft position by sliding the rod to desired length.

Step 2 — Attach the Mounting Rosette
-
Attach the mounting rosette to the flared end of the titanium rod using two M5 button head screws.
-
Adjust orientation as needed:
-
Fore/aft adjustable
-
Can be flipped upside down
-
Can face drive side or non-drive side (under-slung configuration)
-
-
Once aligned, torque both M5 screws to 3–4 Nm.

Step 3 — Attach the Wishbone to the Rosette
-
Align the teeth of the Wishbone Attachment with the teeth on the mounting rosette.
-
Insert the M6 through-bolt.
-
Tighten to 5–6 Nm.

Step 4 — Attach the Mounting Bracket to the Wishbone
-
Align the teeth of the Wishbone Attachment with the teeth on the mounting bracket.
-
Insert the second, M6 through-bolt.
-
Tighten to 5–6 Nm.

Step 4 — Attach your Bottles!
-
Using the slotted holes of the Kappa and Kappa Saddle Cages, install the bottle cages.
- This set up shows one Kappa Cage and one Kappa Saddle Cage. Though there are 26 different boss options for a variety of different bottle configurations.

OPTIONAL:
- You do not need to use the Wishbone Attachment and instead mount the main mounting bracket (indicated in blue) to the rosette (indicated in red).
