Why should you choose our hub?
5 years of research and development to achieve 150T large planetary ratchet structure
150T end gear material CRMNTI, using cold forging technology, CNC five-axis precision machining process. Imported high-end heat treatment equipment for hardening treatment.

Advantage 1: 150T bite area provides more direct power feeling
Advantage 2: The dense 150T tooth arrangement makes the empty section travel smaller, bringing a more direct acceleration experience.
Advantage 3: The mellow 150T ratchet sound brings a different audio-visual experience
Advantage 4: The monolithic vibration bite method makes the 150T ratchet responsive and fast.
Advantage 5: Quickly removable test cassette body makes post-maintenance easier.
Advantage 6: Ratchet tooth body adopts cold forging technology makes wear resistance and toughness increase.
Advantage 7: The end gear surface adopts five-axis CNC high precision machining, to achieve the tooth surface 1:1 completely occluded state


2:1 straight pull braid
The front and rear use crossed hooks with equal holes to make the wheelset more force and torque in the forward and lateral directions. It has stable force performance in cornering and bumpy road when riding



The hub shell part is cold forged with A6061 and then treated with T4+T6, CNC precision machining and then anodized.

Rear hub: 246g   12x142mm


Compatible with HG and XDR cassette body



Frequently Asked Questions:
Hole installation: TR006 for the front 21H rear 24H hole hub, the rim must use the corresponding hole number rim.
Open gear measurement: hub open gear must be consistent with the frame, front fork open gear, such as: front fork open gear 100mm, then the hub open gear must be 100mm
Hub maintenance: Hubs should be regularly maintained and cleaned and oiled during daily use to ensure normal use of the hubs.

Cautions:
1, Please do not use high-pressure water gun to flush the hub bearings for a long time.
2, clutch teeth extreme oil shortage state should be timely use special oil maintenance, please note that the oil only need to add a little.
3, all maintenance should be to the professional repair store for maintenance maintenance, to avoid damage to the hub because of personal error operation.

Warranty rules:
Hub shell: 1 year warranty
Hub tower base: 1 year warranty
