DT Swiss XRC310 DT 240 DEG hand-built wheelset

A DT Swiss XRC310 rim set laced 28-spoke front and rear to DT 240 DEG hubs, built by hand in our Marrickville workshop, tensioned, stress-relieved and trued before it leaves the bench. Our Pro wheel build and tubeless tape fitted are included and show as two free lines in your cart.

Before you order — what your bike decides

Wheel size — 29". Read it off your tyre sidewall.
Rear axle — Boost 12 × 148 or Super Boost 12 × 157. Boost 12 × 148 is most modern MTBs, Super Boost 12 × 157 some Pivot and Knolly frames, 12 × 142 older frames: measure the inside of the dropouts.
Front axle — Boost 15 × 110, 12 × 100 or 15 × 100. Boost 15 × 110 on most modern forks, 20 × 110 on DH forks, 15 × 100 on older forks: check the fork lowers.
Rotor mount — Centre Lock or 6-bolt: look at your rotors (six bolts, or a splined centre with a lockring).

Choose the same rotor mount front and rear unless your rotors differ.

Who it is for

For cross-country racing and marathon riding. Not a rim for jumps or bike parks — see the XM481 trail kits.

The rider's questions

How much can it carry? Max system weight (rider, bike and gear) 120 kg — the DT Swiss XRC310 rating, the lowest-rated part of the build.
What tyres fit? 2.1–2.7" tyres are DT's recommended range for a 30 mm inner width; 1.85"–2.0" and 2.8" are possible. Hookless (TSS) rims: fit tubeless or tubeless-ready tyres only, with or without a tube, and never go above the tyre's marked maximum pressure.
E-bike? DT approves the DT 240 DEG for e-bikes to 100 Nm of motor torque; above 55 Nm DT recommends the 350 Hybrid and above 100 Nm requires it — see our Hybrid and Pro 5e kits for a full-power motor.
How fast does the hub engage? 90 points of engagement — Ratchet DEG 90, 4° between clicks.
Warranty? DT Swiss parts 24 months from purchase; our build work is guaranteed. Any claim comes back to Tune Cycles — see the Warranty tab.
How long does it take? Built to order from supplier stock — we confirm the build date by email when you order.

Everything in the Wheelset box is built in. The rows under Upgrades are optional: tick what you want and the price updates. If you want us to lace a rim or hub you already own, that is a workshop job — contact us for a quote.

Sold separately (shown with this kit): tubeless sealant (Muc-Off No Puncture 140 ml), Deg Df Upgrade Kit (No Tool) — the engagement upgrade that fits this hub, RT-CL700 160 mm Centre Lock rotor, SM-RT66 160 mm 6-bolt rotor, tyres to suit (sizes above). Rotors: one per wheel, to match your rotor mount and your brake caliper's size range.

How we build it

Every wheel is laced by hand in Marrickville, brought up to tension evenly to the lower of the rim and hub limits (1200 N), stress-relieved and trued, then checked again before it is packed. Tubeless tape (32 mm) is fitted to the rim; DT packs its own 32 mm tape and a tubeless valve with each rim, so the valves come with the wheelset — the Pro build and tape are added to your cart automatically; add sealant and it is ready for tyres. The valve row below is only for spares.

Tune Cycles builds and fits these wheels. If you are unsure what your frame, fork or drivetrain takes, ask us before you order.

DT Swiss rims and hubs are covered for 24 months from purchase against material and manufacturing defects (dtswiss.com/en/support/warranty); riding outside the rim's ASTM category voids it. Crash damage on a carbon rim is not a warranty case, but DT's Fair-Share programme replaces a first owner's crashed carbon rim for a fixed fee instead of the full price for ten years from purchase — ask us for the current Australian fee; the claim goes through Tune Cycles and Apollo. Our build — lacing, tension and truing — carries our workmanship guarantee. Any claim comes back to Tune Cycles: bring the wheel to Marrickville or contact us with your order number and we handle it with the brand. Wear, crash damage, corrosion and incorrect fitting are not covered.
