Alfine 8-Speed Disc Brake Rear Hub
Shimano Alfine SG-S7001 8-Speed Internal Disc Brake Rear Hub provides reliable, low-maintenance shifting for city commuting and casual rides. This unit features an eight-speed internal gear system and a 36-hole hub shell, finished in black for versatile frame matching. The rotor lockring is not included, and small parts are omitted in the package, so buyers should verify what’s needed for a complete install. Designed for disc brake setups, it supports sealed operation under varying weather conditions.
For best results, pair with a compatible shifter and frame that supports 36h hubs. The sealed internals reduce exposure to grit and require less frequent adjustment than traditional derailleurs, making it a good option for riders who want consistent performance with minimal maintenance.
- Speed: 8-Speed
- Hub drilling: 36
- Color: Black
- Rotor lockring: Not included
Alfine 11-Speed Disc Brake Rear Hub
The Shimano Alfine SG-S7001 11-Speed Disc Brake Rear Hub expands gearing for more versatile urban riding and light off-road use. This model emphasizes a wide 11-speed range with a clean black finish. It is designed for disc brake compatibility and provides a robust 32-spoke wheel interface. The rear axle is 10×1 threaded x 135mm, and the hub appeals to riders seeking a broad gear set without external derailleur complexity. Small parts are not included, so plan for rotor hardware as needed.
White the hub’s sealed internals guard against grit and weather, it’s essential to confirm wheel compatibility (32h spoke count) and axle requirements before installation. This makes maintenance easier and shifts consistently across a broader range of speeds, especially on hilly commutes.
- Speed: 11-Speed
- Hub drilling: 32 spokes
- Rear Axle: 10×1 Threaded x 135mm
- Color: Black
Nexus 5-Speed Internal Hub
SHIMANO Nexus SG-C7000-5D Internal Hub Gear, 5-Speed, Centre Lock, 36h, Black is a compact internal hub known for dependable performance in city riding. The Nexus line emphasizes simple, durable shifting in a sealed unit. The hub features Centre Lock compatibility for disc rotor attachments and a 36h shell with a 5-speed configuration, enabling smooth, predictable shifts on daily commutes. The product includes a freewheel option in its description, offering a straightforward replacement path for gear-changing needs.
When selecting a Nexus hub, verify compatibility with your frame spacing and shifter choice. Centre Lock can simplify rotor mounting, and a 36h standard ensures broad compatibility with common wheel builds. This hub suits riders prioritizing reliability and straightforward maintenance in urban environments.
- Speed: 5-Speed
- Centre Lock
- 36h
- Color: Black
- With freewheel
Internal Gear Hub Maintenance Oil Dipping Set
SHIMANO Internal Gear Hub Maintenance Oil Dipping Set is a practical accessory for keeping internal hubs properly lubricated. This white-dominated kit supports routine servicing and lubrication, helping hubs maintain smooth operation during regular use. It is an auxiliary tool, not a hub itself, but it contributes to longevity by simplifying maintenance tasks and ensuring consistent lubrication of internal gears.
Regular maintenance is a key factor in extending hub life. This dipping set provides a straightforward way to apply lubrication, reducing friction and wear over time. Use as part of a routine service plan for Shimano internal hubs to maximize performance and reliability.

Alfine 8-Speed Disc Brake Rear Hub (32h)
Shimano Alfine SG-S7001 8-Speed Internally Geared Disc Brake 32h Rear Hub Black, Small Parts Not Included is the 32-hole variant of the 8-speed Alfine family. It shares the same eight-speed internal gearing and disc brake compatibility but uses a 32-hole shell with a center-to-flange measurement of 30.0. The rotor lockring is not included, and small parts may be missing from the package, so buyers should verify additional components required for installation. This hub offers a compact option for frames that use 32h wheels.
When integrating with a disc brake system, ensure that your frame and wheel build accommodate the hub’s 32h drilling and axle specifications. This variant provides the same reliable shifting and sealed internals as the 36h model, with a slightly different spoke count which may affect wheel compatibility and availability of replacement parts.
- Speed: 8-Speed
- Hub drilling: 32
- Center to Flange: 30.0
- Rotor lockring: Not included
Buying Guide
Key considerations
- Gear range: Choose between 5, 8, or 11 speeds depending on terrain and riding style. More speeds offer finer cadence control but may require compatible shifters and frames.
- Hub compatibility: Check hub shell drilling (32h vs 36h), axle dimensions (e.g., 135mm rear, 10×1 threaded), and whether Centre Lock or freewheel configurations are needed for your rotor setup.
- Braking compatibility: Determine if you need a disc brake-compatible hub (Disc variant) or a traditional rim-brake setup, as this affects wheel and frame compatibility.
- Shifter compatibility: Nexus hubs pair with different shifters than Alfine hubs. Ensure your shifter choice matches the hub family for consistent indexing and ease of use.
- Maintenance needs: Sealed internal gears reduce maintenance, but periodic lubrication and inspection are still important. Consider maintenance tools like oil-dipping kits for longevity.
- Frame and wheel compatibility: Verify frame spacing, dropout type, and whether your wheel build supports the hub’s spoke count and axle type for a secure, safe installation.
Riding style and terrain
Urban commuters benefit from 8- or 11-speed hubs for versatile gearing and manageable cadence on varied hills. Riders who prioritize minimal maintenance may prefer a sealed 5-speed Nexus or an 8-speed Alfine with a simplified setup. For occasional light off-road use, an 11-speed hub expands the gear range while retaining reliability in mixed conditions. Always match hub selection to your typical routes and preferred cadence.
Comparison at a glance
- Best overall gear range: 11-speed Alfine for varied hills and cadence flexibility.
- Best for low maintenance: 5-speed Nexus with simple, robust operation.
- Best value in a disc hub: 8-speed Alfine variants offer a solid balance of gearing and braking compatibility.
- Best for disc brake compatibility: Disc-brake-ready hubs (32h or 36h) ensure reliable rotor mounting.
- Maintenance readiness: Include an oil dipping kit to simplify hub servicing and extend life.
