SILCA Hirobel Frame Clamp
Hirobel is a specially designed clamp for bicycle repair stands which makes it easier to work on your bike. It better distributes stresses and loads through the bicycle frame, offering superior stability while eliminating possible crushing or damage to thin-walled and shaped tubing.
Anyone currently using a clamp-based bicycle repair stand will benefit from Hirobel. This includes those seeking improved weight distribution and stability when working on exotic-shaped, oversized, heavy, or non-standard geometry bicycles such as carbon, enduro/downhill, tandem, kid and e-bikes.
The pressure clamps used on contemporary workstands were developed for round steel tubing more than 40 years ago, predating carbon fiber, aluminum, aerodynamic and oversized tube shapes, integrated seat masts, dropper posts, and suspension systems.
These legacy designs assume your bicycle tubing to be both round and straight, and when it is not, the clamp can impart very high point loads at the clamp edges causing finish damage, internal carbon layup damage or outright crushing of tubes on the lightest designs.
With Hirobel, specially shaped, paint friendly cones and bindings cradle the frame at the tube intersections, where wall thicknesses are higher and forces can be distributed over much larger surface areas. Adjustable and adaptable for any possible frame design, the Hirobel also allows the repair stand clamp to be located closer to the bicycle center of gravity, improving stability and eliminating bouncing of the bike during heavier work while also locating the drivetrain consistently higher for the mechanic improving visibility while reducing back strain.
