The Bola 29er carbon MTB wheelset — a 30mm-internal, 30mm-deep rim on DT Swiss 350 hubs with Sapim CX-Ray spokes (~1400g), tubeless-ready for trail and all-mountain.

A proven hub, a modern rim: Bola pairs a 30mm-inner carbon hoop with the dependable DT Swiss 350 hub and bladed Sapim CX-Ray spokes, replacing heavy stock wheels for trail and all-mountain riders.

Buying Guide.

Internal width - 30mm: 2.0-2.6" tires at ~20-25 PSI for trail - run a narrow 2.0-2.2" for XC speed, a wider 2.4-2.6" for enduro grip.

Hub grade - DT Swiss 350: the proven, serviceable hub choice - choose it when reliability, a wide service network and crisp pickup matter over the price.

Build choice: bladed spokes in a balanced build, with HG or XD freehub and 6-bolt or Center Lock - pick the freehub and rotor standard at checkout.

Same-family: the premium build in Bola's MTB wheelsets - the value XMN30 wheelset (BL350, $540) sits below it, and the 29er 6-Spoke Wheelset ($990) above.

Rated to a 105kg system weight.

Target Audience & Usage Notes.

Trail, all-mountain and XC riders wanting a proven-hub upgrade.

The Ride That Awaits.

Open the trail and hear the DT Swiss 350 click crisply into engagement - you put the power down and it goes, no lag, no hesitation. Set it tubeless and the wide rim floats over roots and rock gardens, bladed spokes holding a stiff, precise line through rough descents. Choose your freehub and end caps; a 2-year wheelset warranty means you simply ride.

Trade-offs & Considerations

Aero vs Crosswind: The shallow 30mm rim gains essentially nothing aerodynamically versus a 25mm profile at 40km/h (under 0.5W) and stays calm at 10° yaw on exposed fire roads; the 30mm internal width trades that marginal aero for tyre volume and cornering traction.

Weight vs Stiffness: At 1400g the T1000 carbon build saves about 465g versus a typical 1865g 30mm alloy competitor (±5g), while lateral stiffness stays within 3%; the DT Swiss 350 ratchet adds service reliability over exotic light hubs.

Tire-Type Trade-off: The hooked bead accepts tubeless MTB tyres from about 2.25 to 2.6 inches; tubeless lets you run 20–25 psi for grip, but needs tape, valve and sealant, trading a little pinch-flat margin against rim impacts.

Sourcing & Delivery Trade-off: The stock build ships in 1–3 business days at $890; a custom freehub, decal or lacing adds 7–15 business days and roughly a $60–100 premium.

Config Ladder: The DT Swiss 350 36T ratchet gives 10° engagement with steel bearings; a 54T ratchet service shortens engagement to 6.7° for about +$80, and a ceramic bearing swap cuts about 1.5W of hub friction for about +$120.

How It Compares

FAQ

What tyre widths and pressures fit this wheelset?

With a 30mm internal width, run 2.4–2.6 inch MTB tubeless tyres at about 20–25 psi on trail and 18–20 psi for wider 2.6 inch tyres.

What is the hub engagement?

The DT Swiss 350 hub uses a 36-tooth ratchet, giving 10° engagement — reliable and serviceable for trail climbing and technical sections.

Which freehub body is available?

Shimano HG comes standard; select XDR or XD at checkout if needed for SRAM cassettes.

Is it tubeless ready?

Yes. Tape, valve and spare spokes are included; use a standard MTB sealant, about 2–4 oz per tyre, to seal.

What is the maximum system weight?

120kg. Carbon rims are less impact-tolerant than alloy, so avoid hard strikes against sharp rocks.
