Bike maintenance parts designed to improve hub alignment and reduce drivetrain wear. Cyclists seeking quieter, smoother rides will appreciate the simple upgrade from UIHRLM Bicycle Flywheel Hub Washer Spacer. Could such a small change make a noticeable difference to ride stability?
⚡ At a Glance
- • Fit & Alignment: Seven size spacers for precise axle spacing and reduced cassette wobble
- • Best for: Cyclists who want to fine-tune hub spacing and reduce drivetrain noise
- • Not ideal for: Riders who need proprietary sealed-system spacers or non-standard hub fittings
Seven aluminium alloy spacers cover common thickness needs from 1.0mm to 2.5mm. Slot design helps secure each spacer on the hub to reduce friction and improve ride smoothness.
Precise axle spacing - with seven thickness options
Seven aluminium spacers arrive as eight pieces in total, covering 1.0mm, 1.5mm, 1.85mm, 2.0mm, 2.18mm, 2.35mm and 2.5mm, allowing fine lateral adjustment. Stacking or selecting the correct thickness changes clearance at the cassette and bottom bracket interfaces.
Fine tuning prevents cassette rub and reduces lateral play, leading to steadier gear changes and a smoother ride.
Reduced friction and wear - with correct alignment and seating
Properly aligned hub components reduce unwanted contact between moving parts, lowering friction and mitigating accelerated wear on bearings and cogs. The spacers are designed to sit between hub components to keep axle geometry consistent.
Fewer noise issues and longer component life, so routine maintenance intervals are less frequent.
Secure fit under load - with slot design that limits movement
Slot design helps the spacer mate with the tower base and resists rotation or shifting under pedalling load. Reduced micro-movement at the interface decreases the chance of intermittent rubbing and instability.
More confident rear-wheel behaviour during hard efforts or rough surfaces, with less need for repeated seatings.

❓ Frequently Asked Questions
Q: Are these spacers suitable for road and mountain bikes?
A: Yes. Description specifies use for road and mountain bikes, so the spacers are intended for common bicycle hub setups.
Q: How many pieces and what sizes are included?
A: Seven different thicknesses are included across a total of eight pieces: 1.0mm, 1.5mm, 1.85mm, 2.0mm, 2.18mm, 2.35mm and 2.5mm.
Q: Do the spacers require special tools or professional fitting?
A: No. The spacers are designed for easy installation and removal; they can be fitted onto the axle and tightened without complicated steps or professional assistance.
🏆 Our Verdict
Spacers suit cyclists who want a straightforward way to refine hub spacing and reduce drivetrain noise without specialist help. The combination of multiple thicknesses, aluminium construction and a slotted seating design makes alignment easier and more durable. A small investment in durable spacers delivers long-term value through reduced wear and fewer adjustment visits.
