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 work stands 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.

Not very well designed in my opinion. They should have designed it with removeable round rubber cones with different shapes and sizes instead of the fixed cones. Yes, you can rotate the cones that support the bike but they don't fit very well on wider carbon top tubes.
The rubber belt straps are hard to fit over the pin in the cones and don't fit snuggly because you are always in-between holes; they should have used a ratcheting strap. This would hold the bike a bit tighter and prevent the bike from swinging side-to-side. You don't have side-to-side movement with a seat post clamp like you do with this setup.
For the price, they should have made the pole telescoping. If you aren't careful the extra length of the pole means it will get tangled in handle bar cabling.
To sum it up, overpriced and doesn't work very well.
A very secure way to hold the bike in my work stand. I no longer have to remove the seatpost and insert a metal tube in order to hang the bike on the stand. The bike frame is now in better balance on the frame, with the weight evenly distributed, a great improvement.
Read about it in VeloNews - Mr. Zinn, Tech Guru, mentioned he used to avoid bike stand clamping issues / problems / errors. Very straightforward setup & easy adjustment to fit your Frame. Wide rubber cushions safely support the bike frame even without the straps.
To save the rubber straps & not to rub the top tube, I do not cinch them tight at all.
Well constructed & strong. Yes, a bit pricey - so is the bike frame which will appreciate the extra care.
Wish they included a soft strap to keep the front wheel from flopping but it's an easy fix.
I've got a little basement bike repair biz, and I always worried a bit about clamping carbon seat posts. No more worry with the Hirobel. It also gives me a little more height option which I like too. It does make the bike more stable too. So....it does absolutely everything they say it will do. The price does seem a little high, but I guess Hirobel deserves it for providing such a great solution.
This is a very useful item to have when working on bikes that have curved top tubes and/or not a lot of seat tube showing, like kids bikes, mountain bikes, etc. Got it on sale, and that helped ease the pain, but hopefully it's a "buy once, cry once" type of tool (if the straps hold up).
Was looking for a quick and effective way to put my Madone SLR on a stand, without clamping down on the aero-shaped carbon tubing. Ran across the Hirobel in my online searches and couldn't be happier! Silca is known for high-quality tools, and they did not disappoint Hirobel Frame Clamp!
