The Shimano SG-3C41 hub kit offers a broad 186-percent gear range and includes a push rod, black non-turn washer, and a 3/4″ chain stay clamp. Shifter is not included, so this option is best for riders who already have a compatible shifter or want to customize their setup.

It uses a kick shift mechanism between gears without shifters or cables and features a polished aluminum hub shell. Best for budget-conscious commuters who want simple gearing and a lightweight build. Limitation: two speeds provide fewer options for hills compared with three-speed hubs.

Feature-rich with a 6061 aluminum hub shell, the S-Rc3 is designed for daily commuting and urban riding. It includes a 177-percent gear range, a 18-tooth spline cog, and a compatible thumb shifter. Best for riders who value durability and a tidy, maintenance-free coaster brake setup. Limitation: slightly heavier due to aluminum construction and gearing complexity.
Jstpure 3 Speed Hub Set SG-3C41 36H
The Jstpure SG-3C41 36H rear hub set is designed for three speeds with a coaster brake functionality. Best for riders upgrading a rear wheel with a reliable internal gear system and minimal maintenance. Caution: ensure compatibility with spoke count and frame spacing before purchase.
Buying Guide: Key Purchase Considerations
- Gear range and riding terrain: A wider range (around 177–186%) helps with steeper hills and varied terrain; urban riders often prefer the upper end for city commuting.
- Brake system: Coaster brakes are low-maintenance, but some setups include traditional shifters and cables. Decide whether you want a fully integrated package or a kit you customize.
- Wheel compatibility: Confirm spoke count (36H is common) and axle length to avoid frame and dropout fit issues.
- Shifter and cable requirements: Some hubs include shifters and cables, others do not. Ensure your current bike has the appropriate mounting points or be prepared to purchase extras.
- Installation practicality: Some kits are “ready-to-install” with hardware, while others require additional parts or professional installation.
- Durability and weight: Aluminum shells reduce weight; consider daily-use scenarios like commuting and urban riding when evaluating durability.
- Maintenance needs: Internal gear hubs generally require less frequent adjustments, but alignment and lubrication are still important for longevity.
FAQ
- What is a 3-speed hub with a coaster brake?
It is an internal gear hub offering three forward gear options and a built-in coaster brake for braking via pedaling backward, simplifying maintenance and shifting. - Do I need a separate shifter with these hubs?
Some kits include a shifter, while others require you to supply your own. Check the product features to confirm. - Is a 36-hole wheel compatible with all hubs?
Most 3-speed hubs target 36H wheels, but compatibility depends on axle length and frame spacing. Verify before buying. - Which hub is best for hilly urban commuting?
Hubs with higher gear ranges (around 177–186%) typically perform better on hills, offering more gearing options for steep climbs. - Can I upgrade my current bike to a 3-speed hub?
Yes, many kits are designed to retrofit existing wheels, but ensure frame compatibility, spoke count, and disc or brake clearance if applicable. - What maintenance is needed for coaster brake hubs?
Regular lubrication and occasional drive-side inspection help keep the braking action smooth, with fewer adjustments required than rim brakes.
