Best Rubber and Leather Bit Guards for Curb and Pelham Bits: 2026 UK Comparison of Shires, Korsteel, Nunn Finer, Bobby's and Zilco
Published on Tuesday, 3 February 2026
Bit guards are one of the most underrated components in a rider's tack room, yet they play a real role in keeping a curb or Pelham bit comfortable in the horse's mouth. These small rubber or leather discs sit between the bit cheek and the corner of the lips, cushioning the contact, preventing pinching, and reducing the rubbing that can sore a horse over a long schooling session. For British riders dealing with the UK's damp conditions and frequent washing, choosing a guard that resists perishing and holds its shape makes a tangible difference to both comfort and how long the guard lasts. Whether you're schooling on the flat, hacking out, or preparing for a dressage test, a well-fitted guard keeps the bit sitting correctly and protects your horse's most sensitive areas. This guide compares five widely available options, from low-cost everyday rubber guards through to traditional leather designs that suit classic English tack. Riders often overlook this category until a horse comes in with a rubbed lip, yet a reliable pair of guards costs little and saves a lot of discomfort.
Top Picks Summary
Nunn Finer Rubber Bit Guards
Nunn Finer Rubber Bit Guards are the premium, performance-oriented choice in this list, with a refined rubber compound and finish tailored to minimise chafing and provide a precise fit on curb and Pelham bits. While they sit at the higher end of the price range, their superior comfort, finish and longer lifespan make them cost-effective over time compared with cheaper replacements like Shires or some Korsteel models. For competition riders and sensitive horses needing the best blend of protection and tidiness, Nunn Finer leads here.
Bobby's Leather Bit Guards
Bobby's Leather Bit Guards provide a traditional, high-quality leather alternative to rubber guards, offering a classic look and breathable feel for curb and Pelham bits used in turnout and show situations. Though generally priced higher and requiring more maintenance than rubber options like Korsteel or Zilco, they deliver a smarter appearance and softer contact against the horse's skin, making them attractive where presentation matters more than raw grip. For riders pairing leather tack with traditional bridles who prioritise style and comfort, Bobby's is the refined choice.
These five guards were selected for their fit on curb and Pelham bit cheeks, their effectiveness at preventing lip pinching and rubbing, and their availability through reputable UK equestrian retailers. The line-up spans rubber and leather, budget to premium, so riders can match a guard to their horse, their discipline, and the UK climate.
Understanding Bit Keepers: A Practical Guide for English Riders
Bit keepers and curb chain fasteners serve several essential functions within your bridle system. They maintain precise bit positioning by preventing sideways movement across the horse's mouth, reduce the risk of the bit rotating or twisting during transitions and collection work, minimise pinching of the horse's lips or corners of the mouth, and distribute pressure more evenly across the bars. Understanding these roles helps you appreciate why quality matters in this often-overlooked category.
Stainless steel keepers provide superior corrosion resistance ideal for outdoor storage and frequent washing in British weather
Leather keepers maintain traditional aesthetic appeal and develop character with age, complementing classic English saddlery beautifully
Quick-release designs offer practical convenience for busy yards, particularly valuable during high-volume training periods
Proper keeper installation ensures correct bit geometry isn't compromised, supporting clearer communication and refined control
Regular inspection of keepers prevents unexpected failure during rides, maintaining your horse's safety and your confidence
Compatibility with your specific bridle type and bit system is essential—measure carefully before purchasing replacement keepers
Quality fasteners extend the overall lifespan of expensive bridles by preventing unnecessary wear and stress on leather components

The five products in this guide span the practical range, from the budget-friendly Shires and Zilco rubber guards through the more robust Korsteel and the premium Nunn Finer, to Bobby's traditional leather guards for riders who prefer a classic finish.
