Mavic CXP Pro 30 Disc Rim
The Mavic CXP Pro 30 is the disc-brake version of Mavic's deeper alloy rim: 30mm deep, about 19mm inside, welded and eyeleted, with a UST tubeless bed that seats a tire with a floor pump and a bed wide enough for 28 to 50mm tires. It is the rim for a road or gravel disc bike that wants a stiff, semi-aero alloy wheel with Mavic's tubeless bed, and it is strong enough for everyday and all-road use. This page covers the Mavic CXP Pro 30 Disc Rim.
The CXP Pro 30 is sold here only inside a wheel we build: choose the hub, spokes and nipples in the configurator and the finished wheel ships from Georgia, laced, tensioned and trued by hand.
Design and construction
UST is Mavic's tubeless standard, older than anyone else's, and the Open Pro UST bed is shaped to its tolerances: the tire bead drops into a well and pops onto a precise seat, which is why a UST rim seals with a floor pump when other rims need a compressor. The rim is a 25mm-deep, 19mm-inner double-wall extrusion with a welded SUP joint that is then milled flush, so the brake track on the rim-brake version is continuous, and the ISM4D milling removes material between the spoke holes where the rim carries no load. Eyelets are black to match the matte finish.
How it rides
A CXP Pro 30 wheel is stiff, fast and durable. The 30mm section does not flex under power, the 21mm bed keeps a 30 to 40mm tire stable, and the UST bed seals easily. It is a little heavier than the Open Pro UST disc and a good deal stiffer, which suits heavier riders and all-road use. For a light, comfortable disc road wheel the Open Pro UST is the choice; for a stiffer, semi-aero road or gravel disc wheel, the CXP Pro 30 is the Mavic rim we recommend.

This version
This version is the CXP Pro 30 in 700c, drilled 24h, 32h, about 490g, 19mm inside, 30mm deep, disc. Where the same rim is sold in another size or brake type, that is a separate listing with its own page.
This is the disc-brake CXP Pro 30: plain sidewalls, no brake track to wear, a touch lighter. It fits any disc-brake bike and it is the version most of our customers now build; the rim-brake version is a separate listing.
Sizes, fit and compatibility
The Mavic CXP Pro 30 Disc Rim comes in the drillings listed on this page. It is a disc-brake rim. We build the CXP Pro 30 on DT Swiss 350 and 240, Bitex BX 106, White Industries CLD, Industry Nine 1/1, Hope RS4 and Velocity Race hubs, usually with Sapim Race, D-Light or CX-Ray spokes or DT Competition and Aerolite, and brass nipples.
Tire range on the CXP Pro 30 is 28 to 50mm. The configurator recommends spoke count and lacing from your bike type and weight.
Build it with us
We build this rim to order. Open the Custom Wheel Program with the Mavic CXP Pro 30 Disc Rim already selected and pick the parts around it; it is offered for gravel and road disc, track and road single-speed and touring builds, and the configurator will not let you assemble a combination we would not build.
Spoke head is decided by the hub, not the rim: this rim builds equally well with J-bend or straight-pull spokes, and the configurator only offers the spokes that match the hub you pick.
How Mavic tests its rims
Mavic tests rims and wheels at its Competence Center in Chavanod, near Annecy, France: over 175 m2 for static tests and 360 m2 for dynamic tests, almost 47 tests in all. Mavic states its impact test follows UCI rules pushed to 150%; the wheel must not break or deform. Its climatic chamber cycles rims between +70°C and -10°C at 0 to 100% humidity over several days; the braking test runs 750 braking operations between 0 and 70 km/h; the hub torque test runs 100,000 cycles; the dancer bench simulates 500 km of climbing; front-end endurance covers 7,000 km at 70 km/h, plus field tests of 5,000 km (mountain) and 10,000 km (road). For the Comete 50, Mavic states 57 tests, frontal crash results 50% above UCI requirements, fatigue at 70 km/h under 120 kg equivalent to 700,000 km, and a 120 kg maximum load.
Mavic's warranty is two years; Mavic Care registration within 2 months extends wheels to three years, and registered carbon wheels from the 2021 range onward (serials CFA214xxx or CRA214xxx and above) are covered for life. Carbon crash replacement is 50% off in years 1 to 2, 40% in years 3 to 5 and 30% in years 6 to 8. Many Mavic wheels are UCI approved (dates 06.07.2016 to 19.09.2024).

Everything in this section is published by Mavic. ProWheelBuilder is the wheel builder, not the tester, and the rim reaches us as the maker ships it.
Building it at ProWheelBuilder
Mavic makes the CXP Pro 30; ProWheelBuilder is an independent wheel builder in Georgia, not the manufacturer. Spokes are cut from the ERD we measure on the actual rim, the wheel comes up in stages on a tensiometer, and it is stress-relieved and trued before it goes in the box; tape and a valve go on if you ask.
The configurator filters to what fits, crosses out what is not made, and prices the build as you go.
Warranty
Manufacturer's warranty. Mavic warrants this product against defects in materials and workmanship. The duration, conditions and claim process are set by Mavic and can change without notice, so ask us and we will confirm the current terms before you buy.
ProWheelBuilder. Wheels we build around this part are covered by our own one-year warranty alongside the maker's. Within the year: broken spokes replaced regardless of cause, and the labor on the wheel - truing, re-tensioning or a complete rebuild - included. A manufacturer-covered rim or hub failure is a claim we make and manage for you; one they will not cover is answered with an eligible replacement at 25% off retail. Shipping each way is yours. Parts you supply yourself fall outside it.
Full terms are on our Policies & Warranty page.
CXP Pro 30 Disc Rim questions
What tire width suits this rim?
At 19mm inside this is a road width. It suits roughly 25 to 32mm tires, which is where most road bikes now sit, and it will run a 23 if you still want one. Go much wider than 32 on this rim and the tire starts to balloon above the sidewalls and squirm when you lean on it.
Which spokes and nipples suit the CXP Pro 30?
For most riders a double-butted spoke such as Sapim Race or DT Competition with brass nipples; lighter riders can go to Sapim Laser or CX-Ray. The configurator recommends a gauge and count for the CXP Pro 30 from your bike type and weight.
CXP Pro or Open Pro?
CXP Pro for a stiffer, deeper semi-aero rim; Open Pro for a lighter, more comfortable everyday rim. Both have Mavic's UST tubeless bed.
Is the CXP Pro tubeless?
Yes. It has a UST bed that seats a tubeless tire with a floor pump; tape and a valve are fitted on request.
What tires fit the CXP Pro?
25 to 32mm. A 28mm tire is the usual pairing.
Is there a disc version?
Yes, the CXP Pro 30 disc rim, on its own page.
Is ProWheelBuilder the manufacturer of the Mavic CXP Pro 30 Disc Rim?
No. The rim is made by Mavic; we are the wheel builder in Georgia who laces it into a finished wheel to your spec and stands behind the build.
