Bicycle Parts
Build your own bicycle.
There are many ways to enjoy cycling, and each rider has their own.
Some focus on the type of bike—road, MTB, cyclocross, gravel—
while others explore different styles, like racing, long-distance rides such as brevets, or simply commuting.
Everyone has their own way of enjoying the ride.
Why not build a bike that reflects your style—with parts that suit your own way of riding?
EQUAL is a cycle parts brand designed to help you get even more out of your own style of cycling.

One of the most versatile control levers available today.
Our uniquely developed stepless shifting system breaks down the boundaries between road and MTB, brands and groupsets—giving you the freedom to build exactly what you envision.
The control lever is a product that embodies the very essence of the EQUAL brand concept.
With the optional “Click Plate”, you can achieve a feel that’s closer to that of a traditional lever.
Mechanical Disc Brake Caliper Set
EQUAL mechanical disc brakes offer not only the maintenance reliability unique to mechanical systems, but also top-class braking power and lightweight performance.
They perform reliably even under the intense braking demands of road racing and cyclocross.
They also provide dependable support when dealing with issues during bike travel or long-distance rides.
This next-generation braking system is designed for ease of use across a wide range of riding situations.
MULTI-ADJUSTABLE ROAD PEDALS
We’ve created clipless pedals equipped with every adjustment mechanism you could ask for.
Not only can they help ease joint pain,
but in the process of dialing in the perfect position, you might even discover something new.
These are pedals that make you look forward to the next ride.
Carbon Rim
EQUAL’s carbon rims combine Toray T700 and T800 fibers to deliver a lightweight, high-stiffness, and well-balanced performance.
Choose the model that best fits your riding style.
Disc Hub
At EQUAL, we believe a hand-built hub should meet two key standards:
- Long-lasting performance
- Low-maintenance and easy to service
These may sound like obvious requirements, but we approached them with serious intent and attention to detail.
The result is a hub that’s “ordinary”—but exceptionally good.

L508 Radar Tail Light
Riding on the road is full of dangers.
Especially, safely sharing the road with vehicles is difficult and is a major concern for both parties.

Let’s ride safely and share the road courteously with the L508.

However, the biggest barrier has been the price.
“To deliver power meters to all cyclists,”
with this passion, GROWTAC offers the “Magene PES-P505”
Trainer
⚠️Trainer products are currently available for sale only within Japan.
The concept:“Ride the Road.”
Is the role of an indoor trainer only to boost your heart rate and power meter numbers—
to simply build physical strength?
To truly “ride the road,” it takes more than just the force of pedaling.
You need balance, bike control, and other skills that can’t be measured in numbers.
GT-Roller was developed with one goal: to recreate the movement between rider and bike—just like riding outdoors.
Technique refines power, and power gives life to technique.
GT-Roller believes that mastering both is what expands a cyclist’s true potential.
GT-Roller Q2
The pinnacle of free-motion trainers.
With four rollers that move in sync with your pedaling, it delivers a road-like feel that even allows for out-of-saddle efforts.
Thanks to a redesigned roller geometry, the ride feel has been significantly enhanced over the previous model (GT-Roller Q1.1).
Now comes standard with front anti-drop rollers.
GT-Roller T2
The next generation of three-roller trainers!
A newly designed roller geometry significantly reduces the traditional drawbacks of three-roller systems.
Enjoy stable handling and enhanced safety—less chance of falling forward, backward, or sideways.
Compatible with power training.
The GT-Roller T Series is your reliable partner in performance and progress.
GT-eSMART series
Optional units that bring smart functionality to the GT-Roller series.
“GT-ePower” provides automatic resistance control, while “GT-eSlope” enables gradient simulation.
With “GT-eRemote,” you can easily configure settings and control the system.
These features enrich your training experience like never before.
Bul-Cut3
The biggest concern when doing indoor roller training is the vibration caused by the spinning rollers, which can disturb those around you.
“Bul-Cut3” is a vibration-dampening pad designed specifically for bike trainers to address this issue.
It reduces vibrations generated at speeds of 25–50 km/h by an average of 72%!
iRC ROADLITE HOME TRAINER × GROWTAC
A high-performance trainer tire co-developed by iRC TIRE and GROWTAC.
The vibration generated by tire-drive indoor trainers is greatly affected by tire performance.
In addition to durability, grip that won’t slip is essential.
The ROADLITE HOME TRAINER is purpose-built with every key element a trainer tire needs.
Other Parts
⚠️These products are currently available for sale only within Japan.
“Wouldn’t it be nice if this existed?”
At GROWTAC, we create parts and accessories that bring those ideas to life.
GT-OIL
Bicycles have many components that repeatedly switch between a stationary state and movement.
GT-OIL is a lubricant specially designed to reduce the peak friction that inevitably occurs during these transitions.
It can be used on shifters, front derailleurs, rear derailleurs, cables, and more.
By blending it with GT-OIL HARD, you can customize the characteristics to suit your personal preferences.
Cleat Adjustment Spacer
Differences in leg length or foot tilt (canting angle) between the left and right sides are common.
If you experience knee or foot pain, these imbalances may be the cause.
With the Cleat Adjustment Spacer, you can fine-tune leg length and canting angle for a more comfortable ride.
