We are pleased to announce that VO is the official importer of Growtac Equal Mechanical Disc Brakes into the USA! We currently have them available in Flat and Post Mount brake styles.
If this is your first time hearing about the company, Growtac is a small engineering and manufacturing firm out of Tokyo, Japan that specializes in cycling products for indoor training - think trainers, rollers, and accessories. More recently, they developed a flat mount disc brake that struck my attention when I stumbled across them on an obscure Japanese Instagram story.
Function and Feel
As soon as I saw these, I emailed Growtac and ordered up some brakes for evaluation. A few weeks later, they arrived. We unboxed them, mounted them up on my Pass Hunter and got to work testing them out. Immediately, I found a huge difference in stopping quality compared to the previous calipers. When I say quality, I mean the combination of several things including modulation, stiffness, and lever feel.
Brake modulation is the ability to precisely and accurately control the amount of clamping force on a disc rotor with a given amount of lever input. So, the more lever you pull, a similar amount of deceleration should occur. The rider should be able to feather the brakes to scrub speed, stop firmly before corners, and live comfortably on the edge of peak braking before lockup. Over the years, I've used many different cable actuated brakes from nearly every vendor out there, over a wide range of prices. The Equal brakes have an excellent level of brake modulation compared to other cable-actuated brakes and even some hydraulic set ups.
When you actually squeeze the lever, how does it feel through the pull of the lever? Is it rigidly stiff, is it noodly? I think the easiest way to describe the lever feel is stiff, but forgiving. The lever movement is natural, forgiving to hand muscles, and you never feel like you're going to run out of lever throw. At the same time, properly adjusted, these brakes offer a consistent and reliable bite point that acts as a natural end of the cable pull, without room for additional cable flexion at the caliper.
Please note that the stiffer/stronger the levers you use are, the better these brakes are going to feel. Our Grand Cru short-pull brake levers are a great match for these brakes on flatbar builds. Likewise, the lever feel is going to depend on what dropbar levers you use.
In the past, I've used some brake setups that feel super stiff and good in the stand but lack modulation under moderate braking. I've also tried others where you worry you're going to run out of lever before they get to peak braking. These brakes really seem to be the best we've tried in terms of modulation, lever feel, and adjusting bite point.

These are intriguing! A few questions: Do both brake pads move (as with the TRP Spyre) or is one fixed (like the Avid BB7 and Paul Klamper)? What kinds of brake pads do they take? Shimano? Any recommended disc rotors?
What’s the price?
How close is the blue color to Chris King "matte turquoise"? Looks like it may be closer to their "navy"?
These look really nice.
Do one or both pistons move?
How is the cable clamped? A set-screw?
@Spiff,
They are single sided. The outer piston presses into the inner. We have the Growtac offering but they also take regular Shimano. For the stock resin pads, rotors compatible with resin pads.
@Anon,
Prices are on the website.
@Hobbes vs Boyle,
Not sure - haven't seen them in person. The pictures we post on the site are as close as we can get to real life.
@Anon,
Single piston. A set screw secures the cable.

The Growtac Equal brakes are great. The moment VO had it on stock I got the one in Very Berry. I've been wanting to replace the hydraulics on the Marin Larkspur 2. My first impulse was to look at Paul Klampers, but it wouldn't fit in the very tight space in the rear. The Equals are
almost perfect!
Two things, though:
1) I had to put spacers in the front, between the IS mount and the brake assembly. The Larkspur comes with Shimano 180mm rotors on the front. I'm hopeful VO's IS adapter mounts would eliminate the need for spacers. Would they?
2) The dust cap on the outer pad adjustment is easily misplaced or could come off while riding some rough trails. We'll see.
I don't miss the hydraulics.
You need a 180mm IS adapter
I also bought the same brakes.
By the way, do you sell the nice cable end balls in the photo at your shop?
Yours is similar to ZTTO's 8.6mm one, but it looks smaller. Is it the same?
