A stripped axle nut, a bent skewer, or a worn hub cup can end a ride in the driveway. You need a replacement that matches hub width, thread size, and skewer length before ordering. A quick release skewer is the cam lever that clamps a wheel into dropouts without tools, and its length must clear the frame and brake calipers.
Measure the old axle diameter and length, then compare those numbers with the listed front and rear sizes. That simple check prevents most fit problems and saves a return trip to the workbench.

Meet The Standout Selections
The CYSKY pair suits a straightforward front and rear replacement on road, mountain, MTB, and BMX frames. You get a shorter front set and a longer rear set, which matches how dropouts are spaced. Iron construction keeps the shafts straightforward for basic repairs.
Front hollow shaft measures 10.8cm with a 16cm quick release, while the rear shaft measures 14.5cm with a 19cm quick release. That split matters on a busy weekend, because mixing up front and rear lengths creates a loose clamp. The black finish and 255g total weight keep the kit simple to store in a saddle bag.
Points In Its Favor
- Separate front and rear lengths reduce fitting confusion
- Iron shafts suit common 20 to 28 inch wheel sizes
- Works with 6, 7, and 8 speed road setups
Things To Consider
- Partial plastic components limit strength compared with full steel sets
- Measure dropout spacing before ordering, because length is fixed
Unlike the CYSKY iron set, this AiTuiTui kit pairs Steel 1045 shafts with aluminum quick release levers. That material mix aims for a balance between shaft strength and lever weight. Commuters who remove wheels often will notice the lighter lever feel.
Front shaft is about 110mm with a 155mm skewer, and the rear shaft is about 145mm with a 190mm skewer and 9.2mm diameter. Your existing axle diameter is the key measurement to check, because a mismatch prevents proper clamping. Dustproof caps add a small detail for dusty routes.
Everyday Perks
- Steel 1045 shafts feel sturdier than iron alternatives
- Aluminum levers keep total weight near 270g
- Clear front and rear sizing for 20 to 28 inch wheels
- Black finish blends with most frames
Worth Noting
- Axle diameter must be checked against the old part
- Compatibility is listed for 6, 7, and 8 speed road bikes

Who It Suits Best
Daily commuters and casual riders who need a matched front and rear replacement.
Where Another Pick Suits Better
DEER U Road Mountain Bicycle MTB Wheel Hub Front Rear Skewers QR 145/180 mm suits weight-focused riders who prefer shorter skewer lengths.
Weight stands out here, with a 46g front skewer and a 51g rear skewer for a 97g pair. You get steel and aluminum alloy construction with a smooth cam action lever. On longer rides, that lighter pair matters more than it does on a short neighborhood loop.
Front skewer measures 145mm and rear skewer measures 180mm, with an axle diameter of about 4.5mm. CNC machined alloy hub nuts with a large flange help spread clamping pressure. The sizing differs from the longer 155mm and 190mm skewers in the AiTuiTui kit, so hub spacing needs a careful check.
Useful Touches
- 97g pair keeps rotating weight low
- Smooth cam lever action for quick wheel changes
- Large flange hub nuts improve contact area
Trade Offs
- 145mm and 180mm lengths suit narrower spacing than some sets
- Color options vary beyond black, so confirm the finish ordered
This FOJOO kit solves a different problem from the skewer sets, because it supplies axle nuts and safety washers rather than levers. You get 24 pieces across M8, M9.5, and M10 thread sizes. A household with kids bikes and adult bikes can keep one box ready for tune-ups.
Carbon steel construction with black and silver painted finish resists wear during regular maintenance. Standard metric sizing means basic tools handle installation. The compact box keeps small hardware sorted, which helps in a garage where loose nuts tend to disappear.
Well-Handled Touches
- Three thread sizes cover front and rear hubs
- 24-piece count supports multiple bikes
- Boxed storage keeps hardware organized
- Works on mountain, road, city, and kids bikes
Minor Gripes
- Nuts and washers only, with no skewers included
- Thread size must match the existing axle exactly
Hub overhaul parts take center stage here, with a 190mm axle, two hub cups, and two ball bearing retainers. That bundle goes beyond a simple skewer swap and suits a deeper rebuild. Mountain bike owners facing worn cups will find the included pieces useful.
Axle diameter is 3/8 inch in carbon steel, with hub cups measuring 30.5mm outer diameter and 27mm inner diameter. Ball bearing retainers have a 25mm outer diameter and 12mm inner diameter. You need to match those cup and retainer dimensions to the hub shell before starting a rebuild.
The Value In It
- Includes axle, cups, and retainers in one set
- Carbon steel construction for hub rebuilds
- Detailed cup dimensions aid fit checking
Room For Improvement
- Single 190mm axle limits use to matching hub widths
- Rebuild work requires more skill than a skewer swap

Consider Something Else When
FOJOO Bike Axle Nuts & Safety Washers M8/M9.5/M10 24 PCS suits simple nut and washer replacement without a full hub rebuild.
Chromoly steel hollow axles give this MOONDKIST set a tougher core than ordinary stainless steel options. You get front and rear axles, front and rear levers, and four 25mm hub balls. Trail riders who bend axles on rough descents will appreciate the harder material.
Front shaft measures 10.8cm with a 14.5cm lever, while the rear shaft measures 14.5cm with a 19cm lever. Aluminum alloy levers keep handling light despite the stronger shafts. Rust prevention treatment on the surface helps with wet-weather storage in a garage.
Notable Gains
- Chromoly axles resist bending under trail loads
- Includes four 25mm hub balls for a fuller overhaul
- Aluminum levers balance strength with weight
- Fits 20 to 28 inch wheels and 6, 7, 8 speed setups
Points To Note
- Hub ball size must match the existing hub shell
- Front and rear lengths still require a pre-fit check
Matching Axle Parts To Your Hub And Frame
Length And Diameter Come First
Skewer length and axle diameter decide whether a wheel clamps safely. A front skewer that is too short will not reach the dropout, while an oversized diameter will not pass through the hub. Measure the old part with a ruler and calipers, then match those numbers to the listing.
Material Choice Shapes Strength And Weight
Iron, carbon steel, Steel 1045, and chromoly steel each trade weight for strength. Chromoly and Steel 1045 suit heavier riders and trail use, while aluminum levers and alloy nuts keep weight down. Your riding style should guide the material pick, from commuting to rough trails.
Kit Contents Prevent Repeat Orders
A pair of skewers covers a full wheel swap, while nuts, washers, cups, and retainers cover specific hub jobs. Checking the package list before ordering saves time, because a skewer set will not replace a worn hub cup. Your workshop needs determine whether a simple pair or a fuller overhaul kit makes sense.
Key Considerations Across These Picks
Common Shopping Slip Ups
Ordering by wheel size alone leads to mismatched skewer lengths. Thread size and dropout spacing deserve equal attention, especially on older road frames. A quick measurement session prevents most returns.
What The Higher Tier Buys
Chromoly shafts, CNC machined nuts, and included hub balls add material quality and completeness. That extra spend pays off on trail bikes and hubs that see frequent removal. Basic iron sets remain sensible for light neighborhood riding.
Frequently Asked Questions
How do I measure a quick release skewer for replacement?
Measure shaft length, skewer length, and axle diameter from the old part. Compare each number with the front and rear figures in the listing before ordering.
Are front and rear skewers interchangeable?
Front and rear skewers usually have different lengths for different dropout spacing. Using the shorter front skewer at the rear can leave insufficient thread for safe clamping.
What thread sizes do axle nuts commonly use?
M8, M9.5, and M10 are common metric sizes for front and rear hubs. Matching the thread size to the existing axle ensures the nut seats correctly.
When is a hub cup and retainer kit needed?
A hub cup and retainer kit suits a rebuild with worn bearing surfaces inside the hub shell. A simple skewer replacement will not fix grinding or looseness caused by worn cups.
Do chromoly axles suit mountain bike use?
Chromoly steel offers higher hardness than ordinary stainless steel for trail loads. That hardness helps resist bending on rough terrain, while aluminum levers keep the set manageable.
Final Verdict
For most road and MTB repairs, the AiTuiTui pair offers a balanced mix of steel shafts and light levers. Trail riders may prefer the chromoly MOONDKIST set, while weight-focused riders should consider DEER U. Measure first, then match the material and length to the riding ahead.
