The number one component brand, SHIMANO, the top model Dura-ACE, the crank for the piste.

On the back of the crank is a bold flesh and a rugged arm.
This arm has a hollow structure, so the crank itself can be finished lightly. * The chain ring is not included
This technology seems to be SHIMANO's patent.

・ Octalink standard
In the form of a factory in the map, the rigidity of the BB and cranks is increased by increasing the ground contact surface of the BB and cranks rather than the general square taper like SUGINO.
Rigidity cannot be ignored in bicycle cranks. If you step on it, you will move forward. It is a crank where you can feel such a feeling directly.* BB is not included
A gem with no skiing that is widely used from bicycle racing to streets.
Not only classic bikes, but also modern bikes like Leader are also like an expert and squid.
GOOD is also combined with SUGINO chain ring
