With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Ochain R Spider B1 104Bcd Direct Mount Interface in Black

Season:All Year Round

Brand:Ochain

Code:OC879200R

Ochain R is designed to deliver greater control and confidence across aggressive riding conditions, from full-on downhill tracks to long trail days. Its next-generation spider design allows the chainring to rotate backward, effectively decoupling the rider from pedal feedback forces. This reduces chain turbulence and drivetrain noise, creating a quieter, more stable ride while allowing riders to stay focused on the terrain ahead.

By improving stability while braking and cornering, Ochain R enhances control on rough and technical trails. The external travel adjustment system enables precise tuning of drivetrain behaviour, allowing riders to select the amount of rotational travel to suit terrain, riding style and bike setup. Mounted directly to the crankset, the system delivers consistent performance regardless of cassette gear ratios. The latest generation also features improved impact resistance and enhanced sealing for increased durability and contamination protection.

Key Features:

  • Decoupling System: Spider system that decouples pedal feedback from the drivetrain.
  • External Adjustment: External travel adjustment with selectable travel settings.
  • Enhanced Stability: Improves stability while braking and cornering.
  • Noise Reduction: Reduces chain noise and drivetrain turbulence.
  • Durability: Re-engineered design for improved impact resistance and enhanced sealing for better contamination protection.

Technical Specifications:

  • Compatibility: SRAM 8-Bolt and SRAM 3-Bolt direct mount crank standards.
  • Chainring Compatibility: 104 BCD.
  • Travel Settings: Lock, 3°, 6°, 9°, 12°.
  • Included Components: Ochain R spider, spider-to-crank mounting bolts.

  • Additional Compatibility: Spacers and hardware required for CL56.5 mm DH compatibility when used with DH83 spindle cranks.
  • Service Interval: 100 hours elastomer replacement, 200 hours full service.
