Hello, it's Mittz here! Today let's talk about the crank. For those unfamiliar with it, let me give you a quick explanation of what a crank is.

Understanding the Crank

It's the part where your pedaling force first transfers to. This force then moves the chain, which in turn spins the wheels. Think of it as the heart of your bike; incredibly vital.

Thinking that any crank will do is a misconception. Precision is crucial because it's the first point of power application. To achieve quick acceleration, the crank must be lightweight. A high-precision crank ensures more direct power transfer, making acceleration easier and pedaling smoother.

But does seeking such a crank mean a hefty price tag? Yes, cranks are expensive, but remember, you're investing in the 'heart' of your bike. It’s about getting a durable, high-stiffness crank that lasts a lifetime.

So, which crank should you go for? My top recommendation is this:

SUGINO SG75 Crank

Yes, it's pricey. A complete setup with crank, chainring, and bottom bracket (BB) can exceed ¥100,000. And then there’s the question of which chainring and BB to pair it with. But don’t worry, the SG75 crankset offers a more accessible entry point for beginners.

SUGINO 75 Criterium Crankset

In terms of price, it's comparable to assembling a ROTOR ALDHU set with spider, chainring, and BB. SUGINO, a proud Japanese brand, offers high precision and stiffness, ensuring top-notch quality. In my experience, there’s no crank I’d recommend more than the SG75, evidenced by its high user satisfaction and positive reviews.

Direct vs. SG75

You might have heard direct mount cranks are better due to their high stiffness and minimal energy loss. However, the SG75 is a keirin-grade crank, tested and proven in the intense world of professional cycling. Its smooth operation and exceptional propulsion power are unparalleled.

Design and Compatibility

Its simple yet beautiful design is another highlight. For the minimalist nature of fixed gear bikes, a matching simple crank is ideal. Personally, I prefer it over the bulkier cranks from international brands.

Starting with a cartridge-type BB is fine, as it's affordable and maintenance-free. Eventually, consider upgrading to an NJS-certified cup-and-cone or even a ceramic BB for a remarkably smooth experience. This upgrade is something I and Mizutani-san from the Yokohama store can attest to

In summary, you can't go wrong with the SUGINO SG75. It's a significant investment, but one that won’t disappoint. Give SUGINO a try.
