ENVE Composites M5 Pro Front Disc Brake Rim
The ENVE M5 is the cross-country racing rim in ENVE's M-Series, molded in Ogden, Utah, for riders who want the lightest, fastest 29in wheel that will still finish a World Cup course. It has a 29mm inner width, ENVE's shallow 20mm-class profile for compliance and low weight, patented molded spoke holes and a hookless bead with the wider, blunter wall ENVE introduced on its newest rims. This page covers the ENVE Composites M5 Pro Front Disc Brake Rim; there are front- and rear-specific versions.
The M5 is built to order here. Choose the hub, spokes and nipples in the configurator; the wheel leaves Georgia laced, tensioned and trued.
Design and construction
The M-Series rims share three ideas. The spoke holes are molded, not drilled, so the carbon fibers run unbroken around each hole and the rim keeps its strength where a drilled rim is weakest. The profile is shallow, about 20mm, which is where the compliance comes from; a deep carbon rim is stiff in every direction, and the designers decided a mountain rim should give a little vertically. And the bead wall is wide and blunt on the newest generation, which is how the company cut pinch flats and rim damage compared with its earlier rims.
The M5 applies all of that at cross-country weight: 29mm inner width for 2.2 to 2.4in tires, the lightest layup in the range, external locking nipples and standard J-bend spokes. Front and rear versions differ in layup and, on some sizes, width.
How it rides
An M5 wheel is the definition of a race wheel: it accelerates instantly, it is laterally stiff enough to hold a line through a rooty corner, and the shallow profile takes the edge off chatter in a way that older, deeper carbon rims never did. It is light enough that a full-suspension XC bike on M5 wheels feels like a hardtail on climbs.
The M5 is a cross-country and down-country rim. For trail riding on bigger tires the M6 is wider and tougher; for enduro the M8.

Which version this is
What this listing covers: the M5 in 29in with 24h drilling, about 345g, 29mm inside, 20mm deep, disc. If you need it in another size or for the other brake type, it is listed separately.
This is the disc-brake M5: 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 ENVE Composites M5 Pro Front Disc Brake Rim comes in the drillings listed on this page. It is a disc-brake rim. We build the M5 on the brand's own hubs, Industry Nine Hydra and SOLiX, DT Swiss 240 and 180, Chris King MTB and Hope Pro 5 hubs, usually with Sapim CX-Ray, Laser or D-Light spokes or DT Aerolite and Competition, and brass or alloy nipples.
Tire range on the M5 is 2.2 to 2.4in, tubeless-ready tires only on the hookless bead. Tell the configurator your bike type and weight and it suggests a spoke count and lacing pattern to suit.
Build it with us
We build this rim to order. Open the Custom Wheel Program with the ENVE Composites M5 Pro Front Disc Brake Rim already selected and pick the parts around it; it is offered for mountain bike and MTB single-speed 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.
ENVE Composites's testing and certifications
ENVE makes and tests its rims in Ogden, Utah. For mountain rims it runs three drop tests, each dropping a calibrated weight onto a wheel with an inflated tire. Test 1 (since 2007) strikes both rim walls and is raised until first visible damage; ENVE requires 10 in for XC, 12 in for trail and 14 in for gravity rims. Test 2 (since 2014) strikes one rim wall to mimic pinch-flat hits, requiring 5 in (XC), 6 in (trail), 8 in (gravity) and 10 in (DH race). Test 3 (since 2021) rotates the wheel between hits so every spoke hole is struck, 100-plus impacts per rim. ENVE states the 2024 M6 improved 47% over the M630 and the M8 21% over the M730.
ENVE's Limited Lifetime Warranty covers rims for life for the original owner (proof of purchase required); hub internals and bearings one year; second-hand owners five years from date of manufacture. Crash replacement supplies a new rim at no charge within three years of purchase and at 30% off list price after that. SES 2.3, 3.4, 4.5 and 6.7 tubeless wheels are on the UCI approved list (approvals 24 January to 3 May 2022).

Building it at ProWheelBuilder
ENVE makes the M5 in Ogden, Utah; ProWheelBuilder is an independent wheel builder in Georgia, not the manufacturer, and the factory warranty rides with the rim. The build is the same every time: measured ERD, spokes cut to the half millimeter, staged tensioning with a gauge, stress relief, a final true, and tubeless tape and a valve on request.
The configurator shows only hubs and spokes that match the M5 drilling, strikes through combinations that are not made, and prices the wheel live.
Warranty
ENVE Composites's warranty. ENVE gives the original owner a five-year limited warranty against defects in materials and workmanship, alongside its Lifetime Incident Protection program, which covers rims, forks, bars, stems, seatposts and hubs damaged in riding incidents.
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.
M5 Pro Front Disc Brake Rim questions
What tire width suits this rim?
At 29mm inside this is a trail width, sized around 2.1 to 2.4in tires. That is wide enough to stop a modern trail casing rolling under you in a corner without pushing the tread so flat that it wears down the middle.
What is the difference between the M5, M6, M8 and M9?
Intended use and width. M5 is cross-country at 25mm; M6 is trail at 32mm front and 29mm rear; M8 is enduro; M9 is ENVE's heaviest-duty downhill rim.
Why are there front and rear versions?
ENVE tunes the layup and sometimes the width to the job each wheel does: the front for grip and compliance, the rear for stiffness and impact strength.
Is the M5 hookless?
Yes. Use tubeless-ready tires and stay under the maximum pressure printed on the rim.
Is the M5 made in the USA?
Yes. ENVE molds its rims in Ogden, Utah.
Is ProWheelBuilder the manufacturer of the ENVE Composites M5 Pro Front Disc Brake Rim?
No. ENVE Composites makes the rim. ProWheelBuilder is an independent custom wheel builder in Georgia that builds it into a finished wheel to your spec.
Is it tubeless-ready?
Yes. ENVE Composites lists the M5 Pro Front Disc Brake Rim as clincher tubeless compatible; we tape and fit a valve when you choose the tubeless option.
