VO Chainring Bolts for 50.4 BCD Cranks - Double

VO Chainring Bolts for 50.4 BCD Double Cranks are designed to provide a stronger, more practical, and modern fastening solution for classic 5-pin cranksets. Built for cyclists looking for easier installation and reliable long-term performance, these chainring bolts replace traditional small hardware with a more user-friendly design.

Unlike older systems that use tiny 8mm bolt and nut combinations that can be difficult to install and easy to strip, this upgraded hardware kit uses 5mm Allen head fasteners for easier tool access and improved installation convenience. This design reduces the risk of damaged bolt heads and makes maintenance simpler during crankset servicing.

The kit features durable stainless steel nuts and bolts combined with lightweight alloy spacers, creating a balance of strength, corrosion resistance, and reduced weight. Compatible with Velo Orange, TA, Stronglight, and most other 50.4 BCD cranksets, this kit is suitable for replacing worn hardware or upgrading classic crank systems.

For secure installation and long-term reliability, applying a small drop of thread-locking compound during installation is recommended.
