1. Product Overview

The bottom bracket (BB) cable guide is an essential component designed for bicycle frames with external mechanical cable routing or cables routed from the down tube under the bottom bracket. Its primary functions are to align, guide, and reduce friction for both front and rear derailleur inner cables, ensuring smooth, precise shifting while protecting the frame finish or carbon fiber from cable rub and wear.

2. Specifications & Technical Details

Material: Durable engineering plastic; high wear resistance, low friction, and corrosion-proof against rain and bike washes.
Color: Black.
Mounting Position: Underneath the bottom bracket shell.
Mounting Method: Standard M5 bolt attachment (or pre-drilled frame mount hole).
Compatibility: Suitable for various frame types, including Road, Touring, Gravel, and MTB (compatible with aluminum, steel, and carbon frames).

3. Models & Form Factors (#1 to #6)

Each model features specific cable channels and mounting bolt offsets to fit different frame profiles:

Model #1: Standard basic profile with two parallel guide channels; fits most conventional road and touring frames.
Model #2: Symmetrical elongated channel design with a contoured curve that sits flush against the bottom bracket shell.
Model #3: Asymmetrical extended tail profile, designed for frames where the rear derailleur cable extends toward the chainstay.
Model #4: Features an elongated bolt slot, allowing easy adjustment of mounting position and hole alignment on the frame.
Model #5: Slim profile with extended guide fins to keep cables straight and prevent them from slipping out of the tracks.
Model #6: Wide, contoured profile designed for oversized bottom bracket shells, ensuring smooth cable clearance without rubbing against the frame wall.

4. Key Benefits

Smooth Shifting: Low-friction plastic grooves minimize cable drag for crisp gear transitions.
Frame Protection: Prevents steel inner cables from sawing into paint or bare carbon under the bottom bracket.
Cable Stability: Keeps cables neatly aligned and separated, preventing slack, cross-rubbing, or interference with the drivetrain and tires.
