FIT Bike Co Sealed High Flange 3/8″ Flip/Flop Rear Hub - Gold

The FIT sealed high flange flip/flop rear hub is a classic 36-hole BMX rear hub designed for riders who want the option to run either freewheel or fixed-gear setups. Featuring sealed cartridge bearings, high-flange design, and dual-threaded hub shell in gold aluminum, this hub allows you to switch between riding styles by simply flipping the wheel. The traditional high-flange profile makes this hub particularly well-suited for old-school, mid-school, and cruiser builds.

Key Features

• Classic high-flange design – traditional large-flange profile creates the period-correct aesthetic for old-school and mid-school builds while providing shorter, stiffer spoke angles for improved wheel strength
• Flip/flop hub design – dual-sided threading allows you to run a freewheel on one side and switch to fixed-gear on the other by flipping the wheel, providing versatility without changing hubs
• Accepts large or small freewheels – threading accommodates both standard large (BC1.37 x 24T) and small (M30) freewheel threading sizes for compatibility with various drivetrain setups
• Sealed cartridge bearings – sealed bearing system keeps out dirt and moisture, reducing maintenance frequency and extending bearing life compared to loose ball designs
• Gold aluminum shell – lightweight aluminum construction with anodized gold finish provides corrosion resistance and classic styling that pairs perfectly with FIT's gold high-flange front hub
• 36-hole drilling – standard spoke count balances strength and weight for general BMX and cruiser riding

Compatibility and Ideal Use

This hub requires a frame with 3/8″ dropouts and 110mm rear spacing—the standard configuration for cruisers and many old-school and mid-school BMX frames. Verify your frame's rear spacing before purchasing. The 36-hole drilling is compatible with most rims drilled for 36 spokes. Pairs perfectly with FIT's gold high-flange front hub for a matched wheelset. Best suited for old-school, mid-school, and cruiser builds where classic high-flange aesthetics and 3/8″ axles are preferred. Also works for cruiser riders, fixed-gear enthusiasts, or anyone who wants the flexibility to switch between freewheel and fixed setups without changing wheels.
