Frequently Asked Questions

• How do I pick the right Wheels Manufacturing bottom bracket for my frame and crank?

  Check your bottom bracket shell standard and width (PF30 or BB30, typically 68–73mm, or BSA threaded) and your crank spindle diameter (24mm or 24/22mm). Cross-reference those specs with the Wheels Manufacturing bottom bracket wall chart and tech pages to match the correct model or adapter, and choose machined aluminum, serviceable versions when possible for durability and precise fit.
• What advantages do Wheels Manufacturing machined aluminum bottom bracket cups offer over common plastic PF30 adapters?

  Machined aluminum (anodized) cups provide greater stiffness and long-term durability, reducing creaks and improving bearing alignment compared with many plastic adapters. Wheels Mfg designs are fully serviceable, use Enduro ABEC-5 angular contact sealed bearings with double-lip seals and high-fill grease, and are manufactured in the USA for consistent tolerances.
• How does the Wheels Manufacturing EBB (Eccentric Bottom Bracket) compare to a standard press-fit PF30 adapter for single‑speed conversions?

  The EBB is specifically engineered for PF30/BB30 frames to provide adjustable eccentric chain tensioning and secure crank retention, whereas many press-fit adapters are static and may offer less adjustability. Wheels’ EBBs are serviceable and often threaded or engineered for repeatable installation, giving a more reliable long-term single-speed solution than generic press-fit inserts.
• How do I identify the correct Wheels Manufacturing derailleur hanger or small replacement part for my frame?

  Use Wheels Manufacturing’s hanger and parts reference (search by bike make/model or compare the hanger shape and mounting screw pattern) to find the matching part number; Wheels Mfg is the largest supplier of hangers and provides fit guides to simplify selection. If in doubt, compare photos and measurements from the catalog to your frame’s hanger to ensure proper alignment and bolt spacing.
• Are Wheels Manufacturing bottom brackets serviceable, and what should I expect for upkeep?

  Yes, many Wheels Mfg bottom brackets are designed to be fully serviceable with replaceable Enduro ABEC-5 angular contact bearings and seals for long-term maintenance. Expect to periodically inspect for play or seal wear, follow the product tech guide for disassembly and re-greasing, and replace bearings when performance declines to maintain smooth operation.
