Mach1 Trucky 40 DT 350 hand-built wheelset

A Mach1 Trucky 40 rim set laced 32-spoke to DT 350 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

Rear axle — Boost 12 × 148, 12 × 142 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, 15 × 100, Boost 20 × 110 or 20 × 110. Boost 15 × 110 on most modern forks, 20 × 110 on DH forks, 15 × 100 on older forks: check the fork lowers.
Rotor mount — 6-bolt or Centre Lock: look at your rotors (six bolts, or a splined centre with a lockring).
Cassette — the freehub body follows it: Shimano 12-speed MTB is Micro Spline, SRAM Eagle is XD, Shimano 11-speed and older (and CUES LG) is HG. Offered here: Shimano HG, Shimano Micro Spline or SRAM XD.

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

Who it is for

For cargo, longtail and e-city bikes — the Mach1 Trucky 40 is a 40 mm-inner rim (Mach1 rates it by use: cargo 250 kg, longtail 215 kg, e-trekking / e-city 180 kg, e-MTB 150 kg system weight). DT approves the standard 350 for e-bike motors up to 100 Nm and recommends its Hybrid hubs above 55 Nm — tell us your motor and we will confirm the hub before we build.

The rider's questions

How much can it carry? Max system weight (rider, bike and gear) 250 kg — the Mach1 Trucky 40 rating, the lowest-rated part of the build.
What tyres fit? 2.60–3.3" tyres are Mach1's recommended range for a 40 mm inner width. The tyre's own maximum pressure applies; the rim sets none.
E-bike? DT approves the DT 350 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? 36 points of engagement — Ratchet System 36 SL, 10° between clicks. The 54 SL Star Ratchet kit is a drop-in upgrade (sold separately).
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 — 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), RT-CL700 203 mm Centre Lock rotor, SM-RT66 203 mm 6-bolt rotor, the Shimano SM-RTAD05 adapter (runs a 6-bolt rotor on a Centre Lock hub; not with SM-RT86 / RT76 aluminium-carrier rotors), a cassette for your freehub body, 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 (42 mm) is fitted to the rim; add valves and sealant and it is ready for tyres.

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 hubs are covered for 24 months from purchase against material and manufacturing defects (dtswiss.com/en/support/warranty). 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.
