HOPE MONO PAD PIN CLIP

The Hope Mono Pad Pin Clip is a genuine factory replacement backup clip designed to safely lock your disc brake pad retention pin into the caliper housing, preventing mechanical failures on rough trails.

When you are rattling down fast, technical fire roads or dropping into steep singletrack descent sectors, the security of your braking system is everything. The Hope Mono Pad Pin Clip—known officially by part number HBSP171—is a tiny but critical component that provides vital peace of mind for your cockpit setup. Positioned neatly on the exposed tip of your caliper’s pad retention pin, this spring-steel clip acts as an absolute safety lock, ensuring the threaded pin cannot vibrate loose or back out of the caliper body even under continuous heavy vibration.

Over time, during frequent brake pad swaps or routine maintenance bleed procedures, these small R-clips can easily spring away across the garage floor, warp out of shape, or succumb to metal fatigue. Running your brakes without one leaves your pad assembly vulnerable to migration, which can cause sudden pad misalignment or severe brake drag. Precision-stamped to authentic UK factory specifications, this original replacement clip slips smoothly into place over the retention pin groove, restoring the dual-redundant safety mechanism that premium Hope engineering is famous for across road, gravel, and mountain bike disciplines.

• Multi-Generation Compatibility: Universally fits a broad array of classic and modern Hope calipers including the legendary Mono series, Tech, Tech Evo M4, X2, and V2.

Specifications

✅ Why This IS For You

• ✅ The Prepared Trail Rider: You like to keep a few vital, cheap spares in your ride pack so a lost hardware clip out on the singletrack doesn't end your weekend trip.

• ✅ The Dedicated Home Mechanic: You are replacing worn brake pads or performing a full fluid flush and want fresh, crisp hardware to finish the rebuild perfectly.

• ✅ Premium Hope Owners: You demand the perfect fit and materials of genuine UK-made components over loose-fitting generic hardware store fasteners.

• ✅ High-Vibration Trail Sessions: You regularly ride aggressive downhill, enduro, or rocky technical terrain where component vibration levels are extremely high.

❌ Why This May NOT Be For You

• ❌ Centerlock Lockring Users: If you are confusing your brake pad hardware with hub rotor lockrings or caliper mounting adaptors, this micro-pin clip will not serve that purpose.

• ❌ Other Brake Brand Owners: This safety clip is specifically dimensioned to snap onto the exact diameter of Hope retention pins; it will not fit Shimano, SRAM, or Magura pin profiles.

• ❌ Riders Needing the Main Bolt: This product contains the tiny external backup safety clip only; it does not include the long threaded titanium or alloy pad pin itself.

BFC PRO TIP

Because these little R-clips are highly sprung and incredibly lightweight, they have a frustrating habit of pinging off your fingers and disappearing into the darkest corners of your workshop floor during pad changes. To save your sanity, always place a bright white rag or towel directly underneath the brake caliper on your work stand before removing the old clip. When pushing the new clip into place, use a flat set of needle-nose pliers to guide it steadily until you hear a clean "click"—this keeps the clip fully controlled and prevents it from flying away into the garage abyss!
