Hello, this is Ren.

A fixed gear bike is a single-gear bicycle with no gear shifting.
This is the simplest structure of any sports bike.

We all already know that.
So, does the pedaling weight on all fixed gear bikes have the same effect? ​​No, it doesn't.
It is possible to make it lighter or heavier by changing gears.

This is done by setting the gear ratio.
By changing the number of teeth on the "chain ring" attached to the crank and the "cog" attached to the wheel, you can change the gear ratio to suit your riding environment and the speed you want to go.

However, the basic premise for this is that both the chainring and cogs must be customizable.
Cogs can be customized using the wheels that come with a complete bike, so people often change them, but I don't think people customize chainrings very often.

Because in order to customize the chainring you first need to customize the crank.
The original cranks that come with most complete bikes have a "5-pin" standard of "PCD130" that secures the chainring.
In contrast, commonly seen high-end parts from manufacturers such as SUGINO, PHILWOOD, DIGIRIT, and BOX14 are compliant with the "PCD144" standard, so they cannot be installed.

In that case, crank customization is essential for customization.

Furthermore, the crank is the heart of a fixed gear bike.
The rotation and rigidity of this part make a difference in the power transmission, and customizing it will give you more speed and comfort than ever before.
That's why we at BROTURES staff choose the best cranks possible.
Once you customize it to something good, you can continue to use it for a long time without having to make any changes, so we recommend that you try customizing the crank first.

Here are the best cranks I recommend.

1. SUGINO 75 CRANK

This is a classic crank that boasts the highest approval rating at BROTURES.
Japan is known for its keirin races. This is one of the few models allowed for use in the main track, and it is designed to withstand even the fastest speeds of over 80km/h thanks to its fearsome gear ratio.

The colours available are silver for athletes and black for general use.
Even though they only needed to make it in silver, they made it in black for us fixed gear riders, which is great.
You can choose how you want to assemble it, so if you want an all-black look, go for the black option.

In addition, this crank is available in three BB grades , from the affordable, maintenance-free cartridge type to the cup and cone type, which allows you to adjust the rotation yourself.
The higher-end cup and cone models use ceramic bearings, which eliminate metal expansion due to friction and are reliable enough to withstand high speed revolutions.
I think you should choose this grade according to your driving style.

2. SHIMANO FC-7600 DURA ACE CRANK

Like the SUGINO mentioned above, this is also an NJS certified crank.
I use this one too, and it spins well so my friend really likes it.
Also, compared to the SUGINO, this one is about 30g lighter .
The pedaling feel of the SUGINO 75 is firmer and gives a feeling of being able to push down harder, but this one is not inferior.
In fact, the slightly softer branch gives it a more flexible feel than the SUGINO 75.

This model is only available in silver, and the only BB option is basically the HATTA R9400, so I personally like the fact that if you want to use this, you can easily choose this combination.
Of course, the HATTA 9400 is an NJS certified product, so it spins like crazy. It really spins like crazy.
If you have a silver crank, you might want to go for DURA ACE, and if you have a black crank, you might want to go for SUGINO 75.

3. ROTOR VEGAST CRANK SET

The atmosphere has changed completely, with a new disc-shaped structure.
Until now, SUGINO 75 and DURA ACE have been positioned as classic masterpieces that will always be around, but this new product is rather a crystallization of the latest technology with a top-notch precision structure in the current environment.

It is made extremely lightweight by computer-controlled cutting of a block of aluminum and grinding it down to the bare minimum.
Furthermore, although this crank is a direct crank, the spider and arm are separated, allowing you to upgrade just the arm.
The highest grade model comes with carbon arms, making it incredibly light.
But the power transmission is top-notch. So good that even if you use the same gear ratio, you might mistakenly think that the gear ratio is lighter if you use this crank.

This crankset is the entry level grade.
Therefore, the BB and chainring are all included. Normally, they are all sold separately, but with this you can just put them on and enjoy them right away.
The pedaling feel is excellent as it is, but if you like it, you should consider upgrading the arms even further.

4. BROTURES ALLDAY CRANK SET

Lastly, here's our original.
This item is a modified version of a previously released model that has been further improved for a more comfortable ride.
The BB type is square taper and the chainring standard is PCD144. Therefore, it is compatible with high-grade chainrings such as SUGINO and PHILWOOD.
There is also an update to PHILWOOD BB.

The colors available are polished and black, so you can choose to match your customizations, making this a great option for those who want to change to the cranks I introduced earlier but want to start with something more affordable.
This crank is seriously the best value for money.
Have fun customizing your chainring with this crack, and then update your cranks.

These are the best cranks I can think of.
Everyone, please aim to create these cranks and enjoy customizing them.
