Race / Fitness Bike Chain Lock Holder

This minimalist chain lock holder is designed specifically for race and fitness bikes, where clean looks, low weight, and functionality matter.
Main function is so that a carbon bike does not get damaged from the chains impacting the frame while having more protection than the foldable locks.

Unlike standard holders, this design allows your rear light to remain visible when the lock is mounted correctly—helping you stay safe without compromising the bike’s aesthetics.

The holder keeps the chain lock close to the frame to minimize movement and rattling, while maintaining a sleek, aerodynamic profile. It’s ideal for riders who want a practical solution that doesn’t interfere with essential safety equipment.

This holder offers a simple, lightweight (apart from the heavy lock itself ;) ) way to carry a chain lock while keeping your rear light clearly visible.

Features

• Rear light remains visible when used properly
• Slim design suitable for race & fitness bikes
• Secure chain lock positioning
• Reduced vibration while riding
• Clean, minimal appearance

Required Items

• 2 zip ties
  (Note: future update will expand this to 3 zip ties or screw add-on)
• Optional but recommended: a small piece of ~1 mm rubber (e.g. cut from an old inner bike tube) to improve grip and protect the frame

Intended Use

For bikes with a 27mm thick seat post that is , added 2mm of room for the inner tube.

Great for commuting, or short stops where you want to carry a chain lock without blocking your rear light.
