Following the cog and hub from By BROTURES, the crankset—complete with BB and chainring—has just arrived. It's no exaggeration to say that this one part can completely transform your riding performance.
The BEAT CRANK was designed with the hope that it would make city riding smooth and rhythmic, allowing you to keep moving freely and effortlessly without stress. Simple yet thoughtfully designed, its look is carefully calculated to complement a wide range of frame designs without clashing.
Let me go into more detail about the BEAT CRANK this time!
1, Combination All the Good Points of Previous Cranks
Direct cranks are produced by many manufacturers, such as SUGINO 75 DD, SRAM OMNIUM, MICHE PISTARD AIR, and VISION. Additionally, we previously developed our own original crank, the RIP crank. We are confident that we are the ones who have worked with direct cranks for fixed gear bikes the most.
That's why, we were able to start this project by comparing the advantage and disadvantage of various cranks.
First, we designed the crank with a one-bolt fastening system for attaching both arms considering ease of maintenance and ensuring rigidly which ins important for daily use.
From my experience, this type of crank does not cause much noise or rattling. Durability, being able to withstand daily commuting and hard riding without breaking, is an essential factor.
Additionally, the spindle is made of solid steel. The spindle is a crucial part that supports the pedaling force, so we apply a special hardening process called 'heat treatment' to enhance its strength and minimize power loss to the greatest extent possible
Compatibility is a common concern for any crank, and it's often difficult to determine whether a specific crank can be installed, especially when it's unclear whether it will match the frame. To eliminate compatibility issues as much as possible, we’ve paid close attention to the length of the included bottom bracket and spindle—down to the millimeter—so that it can be installed on most frames. (There are a few exceptions.)
As mentioned above, this BB standard is HOLLOWTECH II. Some manufacturers like PHILWOOD release custom parts. The product includes the BB and chainring, but it's a great option for customization if you are looking for higher specifications.
2, Good Response Should Be Specially Mentioned
In addition, I would like to introduce the "Material" used.
The crank is made from aluminum AL7075, which is known for its hardness and its commonly used in real race scenes. DURA-ACE, the flagship model from SHIMANO, is also known to be made from AL7075.
However, BROTURES' main focus is not on the race track. After carefully considering which material would provide the most comfortable and enjoyable ride for city use, we choose AL7075.
It's said that leg strength can be three to four times greater than arm strength, and since the crank continuously receive that energy, using a stiffer materials helps minimize power loss to the rear wheel. As a result, it delivers a crisp and responsive pedaling feel.
Thanks to its quick response, its easy to control pedaling power especially in city riding and heavy traffic. This crank is characterized by its sharp reaction when the light turns green and its smooth acceleration.
Due to the crank arm's rigidity, there is minimal power loss, allowing for a smoother ride even with a higher gear ratio than usual. Personally speaking, I think setting the gear ratio to over 3 is no problem if you use this BEAT CRANK.
Additionally, the chainring is made from AL7075 as well. It transfer power from your leg to the chain directly, giving you a smooth and responsive feel from the rear wheel.
3, Our Reason Behind Creating the BEAT CRANK
Actually, we had reasons that cranks are important part in fixed gear, or we hadn't released the new crank since the RIP crank.
However, our biggest motivation came from the recent rise in commodity prices. Cranks have been particularly affected by this issue, even more so than other fixed gear components.
In addition to the rising cost of raw aluminum, cranks require advanced manufacturing techniques, making them difficult to produce. As a result, price increases have been unavoidable. Naturally, there are no direct cranks on the market in an affordable price range, and high-demand brand cranks are being sold at prices ranging from $400 to $900USD. They have become luxury items—no longer something that easily fits within the realm of “casual customization.”
Just 10 years ago, many riders installed cranks like the SRAM OMNIUM or SUGINO 75 on their bikes and enjoyed customizations whether by imitating their favorite riders or adjusting to their own riding style. However, in recent years, we have seen more and more people unable to customize key components like cranks or wheels due to the rising cost of materials.
Even we, who firmly believe that "the true essence of fixed gear bikes is customizing and riding them," sometimes hesitate to make such recommendations to customers.
As mentioned earlier, the crank, being the "heart of power transmission," is a crucial component that greatly influences the joy of riding. While we don't claim that the BEAT CRANK is the perfect answer for everything, we hope it will inspire more people to discover the fun of customizing their fixed gear bikes, starting with the crank.
We want people today to experience that same feeling we had back then. This is not just a case of "we made it cheap to go against rising prices." While we did our best to keep the price as low as possible, we created this product as something we can confidently recommended to our customers. That mindset applies to all of BROTURES' original items, but this crank may be the one we developed with the strongest passion.
For those who have not experienced the world of fixed gear bike customization yet, we hope the BEAT CRANK will be the starting point for them to feel the difference in ride quality.
For those who have already started customizing but haven't been able to upgrade their crank due to high costs, this product might be a special opportunity to finally feel satisfied.
