The Silca Hirobel Frame Clamp System is the ultimate bicycle repair upgrade. A specialised design offers superior stability whilst caring for your frame. The Hirobel is fully adjustable and adaptable giving the perfect clamp whatever kind of bike you ride. Whether you’re working on an enduro frame, e-bike, non-traditional oversized carbon, or even a tandem, the Hirobel gives a tailored fit meaning you can devote your entire attention to the task at hand.If you use a clamp-based repair stand to work on your bike, it’s critical that the load is distributed evenly to reduce stress on the frame. Where weight distribution is compromised or unnecessary compression is applied through clamping, you risk damaging your frame tubing. The Hirobel eliminates this worry - you can always be confident that you’re caring for your bike whilst maintaining and repairing it.The versatility of the Hirobel derives from its specialised design. The ergonomic cones and binding cradles utilised are paint-friendly and can be positioned easily at frame intersections – where tube thickness is greater – to give the perfect weight distribution and a carbon-optimised hold.Because the Hirobel system is fully adaptable to your specific frame, it enables a close fit with any bicycle repair stand. This offers greater stability, improved comfort and crucially eliminates bike-bounce and unwanted vibrations during heavier work on your bike. Simply clamp the Hirobel to your repair stand and enjoy the very best maintenance experience.Key Features: Fully adjustable and adaptable for all frame geometries and materials,Optimal compression and weight distribution,Ergonomic cones and bindings for a paint-friendly and secure clamp,Greater stability and better positioning for improved comfort.
Designed to alleviate damage and crushing to thin-walled tubes, the Hirobel enhances weight distribution and stability on a variety of bike shapes, constructions and sizes. It uses specially shaped, paint-friendly cones and bindings to hold the frame where your tubes meet, allowing for forces to be more evenly distributed across larger surface areas. The design of the clamp means it can be placed close to your bike's centre of gravity, reducing movement during work while giving a clearer eyeline to your drivetrain.
Silca Hirobel Frame ClampDesigned and engineered for use with clamp style repair stands, this clamp loops around your bikes frame and is then held in place by your bike stand. This unique design provides superior workshop stability and eliminates possible crushing or damage to thin-walled, shaped and carbon tubing. Improved Weight Distribution and Frame Friendly MountingThe Hirobel Frame Clamp is a superb option for riders and mechanics wanting improved weight distribution when working on bikes. This design is perfect for mounting exotic-shaped, oversized and non-traditional geometry shaped bikes, such as carbon, enduro, downhill, tandem, kids and E-Bikes without any risk of damaging the frame or paintwork.Features: Fully adjustable so it fits all frame geometries and materials Specially designed to mount your bike to clamp style repair stands Better distributes stresses and loads throughout the frame during maintenance Provides greater frame stability during use and eliminates possible crushing or frame damage Ergonomic cones and bindings for paint-friendly fitting and safe secure clamping Repair stand mounts closer to your bikes centre of gravity for improved stabilityBuy Silca Workshop from Chain Reaction Cycles, the World's Largest Online Bike Store.
