Bike hubs: cartridge vs cup and cone

The evidence here is thin: few independent tests, so treat the numbers as a starting point. 12 sources, listed at the end.

What the tests say

Two bearing designs. A cup-and-cone hub has loose ball bearings running between an adjustable cone threaded onto the axle and a race pressed into the hub shell. It “can be easily disassembled for lubrication, but it must be adjusted correctly”¹. A cartridge bearing packages the balls and both races in one sealed unit. It is “generally not serviceable or adjustable”, so the whole cartridge is replaced¹. BikeRadar’s buyer’s guide (Sept 2026) says cup-and-cone is most common on entry-level wheels².

Adjustment is fiddly. Sheldon Brown notes corrections “on the order of 1/10 of a turn or less” can be needed. With quick-release axles, the right adjustment leaves a little play when the wheel is off the bike, because clamping the quick release compresses the axle and takes up that play³. Park Tool’s Shimano hub procedure agrees: adjust in small increments so the bearings are as loose as possible without lateral play or knocking, and allow only a very slight amount of play out of the dropouts¹².

Service intervals (manufacturers). DT Swiss recommends hub maintenance annually in normal conditions and every 3 months in extreme ones, giving dust, rain, snow and frequent transport in the rain as examples. It also says warranty claims can be refused if maintenance is neglected⁸. A DT Swiss note on its 180 hub adds that the freehub body should be checked and cleaned at least once a year, and every 3 months in wet and dusty conditions⁹. Chris King recommends a basic service (Ring Drive maintenance) every 12 months¹⁰ and a simple bearing service every 6–12 months¹¹. None of these give a distance. Shimano doesn’t publish a general service interval.

Freehub vs freewheel. A freehub builds the coasting mechanism into the hub, and the cassette slides onto its splines⁷. Shimano made its first freehub in 1978⁴. Moving the drive-side bearing nearer the dropout made bent and broken axles “far less common” than with screw-on freewheels⁴.

Engagement. Points of engagement (POE) is how many positions per revolution the hub can catch, so the engagement angle is 360° ÷ POE (our arithmetic):

• Hunt’s H_Ratchet XL uses two 40-tooth ratchet rings, so it engages every 9°. Hunt says that angle is “deliberate”, trading quicker engagement against pedal kickback⁵.
• ENVE’s SES 4.5 uses a 40-tooth ratchet, also 9°².
• Zipp’s 303 Firecrest has 66 points of engagement, about 5.5°².

These are manufacturer specs. No independent test shows that faster engagement makes anyone faster on the road. Its practical value is mostly in technical MTB riding, where you ratchet the pedals in short bursts (a common view, not a tested one).

Friction is small. SILCA puts a full ceramic bearing upgrade for its Zipp 404 Firecrest example wheelset at about 0.8–1.0 W⁶. That’s smaller than the tire effects and. There’s no published study or independent test of bicycle hub bearing friction.

Seals, dust and durability. DT Swiss counts dust as an extreme condition⁸, and Hunt describes seals designed for mud and dust⁵. No independent data compares the life of cup-and-cone and cartridge hubs, or the reliability of pawl and ratchet freehubs.

The numbers

• DT Swiss: hub maintenance annually (normal use), every 3 months (extreme use)⁸
• DT Swiss 180: check and clean the freehub body at least yearly; every 3 months if wet and dusty⁹
• Chris King: basic service every 12 months; bearing service every 6–12 months¹⁰¹¹
• Cup-and-cone adjustment can need changes of 1/10 turn or less³
• Shimano’s first freehub: 1978 (Dura-Ace and 600)⁴
• 40-tooth ratchet = 9° engagement (Hunt H_Ratchet XL, ENVE SES 4.5)²⁵
• 66 points of engagement ≈ 5.5° (Zipp 303 Firecrest)²
• About 0.8–1.0 W: SILCA’s estimate for a full ceramic bearing upgrade on a Zipp 404 Firecrest wheelset⁶

Myths and disagreements

• “Cup-and-cone is obsolete.” It’s adjustable and easy to service. It needs correct adjustment, which cartridge bearings don’t¹³¹².
• “More engagement points is always better.” Hunt chose 9° deliberately, citing pedal kickback (a manufacturer view)⁵. There’s no independent performance data.
• “Ceramic bearings are a big upgrade.” About 1 W for one example wheelset, by SILCA’s estimate⁶.
• “There’s a standard service interval in kilometres.” The two makers found give time-based intervals only: annual for DT Swiss and for Chris King’s basic service, plus 6–12 months for King’s simple bearing service⁸¹⁰¹¹.

Looking after your hubs

• With the wheel in the bike, rock the rim side to side. Any knock means bearing play. With the wheel out, turn the axle by hand. Grittiness means service time³. These are basic shop checks.
• On cup-and-cone quick-release hubs, leave a hair of play off the bike, so it disappears when the quick release is clamped³¹².
• Service at least yearly, or follow your hub maker’s schedule. DT Swiss’s own “extreme” list includes dust, so a desert rider on dusty roads might shorten freehub cleaning to quarterly (our reading of that list)⁸⁹.
• If the freehub skips under load or clicks unevenly, it needs servicing or new pawls or ratchet rings. Follow the hub maker’s procedure, since designs differ⁴⁵.
• Don’t buy ceramic bearings for speed. Spend that money on tires first⁶.
