Top 5 Replacement Parts and Repair Kits for Curb and Pelham Bits in the United States (2025) — Expert Guide to Mouthpieces, Shanks, Screws and DIY Kits

Coronet's Curb Chain Replacement Kit earns its best-in-class spot by bundling multiple link sizes, quick-fit hooks and a clear fit guide that makes it the most complete out-of-the-box option for replacing curb and pelham bit chains. It is priced competitively against more specialized hardware like Metalab's hooks and is especially strong for owners who want a full repair solution rather than buying individual parts. Compared with shank-specific sets such as Reinsman's, Coronet focuses on versatile chain compatibility and value for everyday maintenance.

Metalab's stainless steel curb strap hooks stand out for their heavy-gauge corrosion resistance and precision forging, giving them a longer service life than many economy hooks found in generic kits. Technically superior for wet or marine environments, they command a modest premium over basic kits like Weaver's but offset that cost with durability that reduces replacement frequency. While not a full repair kit like Coronet's offering, Metalab hooks are an ideal high-performance upgrade when pairing with Myler mouthpieces or Reinsman shank sets.

Although a mouthpiece rather than a parts kit, the Myler MB-02 is included here because it functions as a direct replacement centerpiece for many curb and pelham conversions, offering an anatomically contoured profile that promotes acceptance and rider control. Its higher price reflects precision machining and rider-comfort benefits compared with generic mouthpieces, and it pairs especially well with quality chains and hardware such as Coronet or Metalab components. For owners repairing a complete bit setup, replacing a worn mouthpiece with the MB-02 is often a higher-impact, performance-focused upgrade than swapping minor fittings alone.

Reinsman's Stage B Shank Replacement Set is the market leader for shank-specific repairs, offering matched geometry and stainless hardware that restore the leverage and action of pelham-style bits to show-legal standards. It is technically more specialized and typically more expensive than chain-focused kits from Coronet or Weaver, but necessary when shank wear or damage affects bit performance rather than just fittings. Riders who need a like-for-like shank swap will find this set superior to piecemeal repairs because it preserves original bit balance and action.
