Pre-Order

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

Praxis Works BB Conversion Shimano 24mm Road 68mm BB30/PF30 Ceramic in Black

Season:All Year Round

Brand:Praxis Works

Code:PR-68-5001R

The Praxis Works Shimano Hollowtech II bottom bracket converter is designed for installing Shimano Hollowtech II cranks in BB30, PF30, or Specialized OSBB road frames. This converter features high-grade Enduro 2437 ceramic cartridge bearings that are fully sealed for durability. The patent-pending design positions the cartridge bearings outboard of the frame, matching Shimano specifications for increased rigidity and eliminating frame or c-clip tolerance issues common in other conversion systems.

Installation involves pressing in the longer non-drive cup, followed by threading the shorter drive cup into it. As the drive cup is tightened, the Praxis Works trademark Collet system expands to a precise limit, evenly dispersing pressure for a secure, wiggle-free fit. This ensures the bearings remain perfectly aligned. A compressible o-ring on the non-drive side cup further compensates for any frame shell width discrepancies.

Technology:

  • Compatibility: Designed exclusively for Shimano road cranks.
  • Design: Patent-pending outboard bearing configuration.
  • Collet System: Non-drive cup expansion ensures a wiggle-free press fit.
  • Adjustment: Non-drive o-ring compensates for frame width variations.

Installation & Compatibility Notes:

  • Frame Compatibility: Suitable for BB30, PF30, and Specialized Road OSBB Aluminium frames.
  • Exclusions: Not compatible with BBRight, 386EVO, or Cannondale BB30A/PF30A frames.
  • Obstructions: Frame shells must be free of internal obstructions, such as cable guides or screws, that could prevent installation.
  • Crank Restrictions: The 68mm road version is not intended for use with MTB cranks.
  • Specialized OSBB: Requires the 68mm OSBB sleeve for installation.
  • Tools Required: Installation requires two standard bottom bracket tools with 16 external notches and a 44mm ID, along with a press tool or drift.

Warranty:

Praxis Works warrants components to be free from defects in materials or workmanship for a period of 2 years after the original purchase.

Technical Specifications:

  • Material: Forged and machined heat-treated 7075 T6 Aluminium.
  • Bearings: Enduro 2437 ceramic cartridge bearings.
  • Frame Standard: 68mm Road.
