DT Swiss XR421 Hope Pro 5 hand-built wheelset

A DT Swiss XR421 rim set laced 28-spoke front and rear to Hope Pro 5 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 only on this wheelset: 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. Colour: pick front and rear separately.

Who it is for

For cross-country racing and marathon riding. Not a rim for jumps or bike parks — see the XM431 trail kits.

The rider's questions

  • How much can it carry? Max system weight (rider, bike and gear) 120 kg — the DT Swiss XR421 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"–2.05" and 2.8" are possible. The tyre's own maximum pressure applies; the rim sets none.
  • E-bike? Hope makes the Pro 5 E for e-bikes — see the Pro 5e version of this set.
  • How fast does the hub engage? 108 points of engagement — Hope Pro 5 (6 pawls, 3 engaged), 3.33° between clicks.
  • Warranty? DT Swiss parts 24 months from purchase; Hope hubs under Hope's manufacturer warranty through the Australian distributor; 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.
  • Colours? Hubs in Black, Silver, Blue, Bronze, Orange, Purple or Red; the rims are black.

Kit includes

Options: rim diameter 29" · rotor mount 6-bolt or Centre Lock · rear axle Boost 12 × 148 (Super Boost 12 × 157) · freehub Shimano HG, Shimano Micro Spline or SRAM XD · hub colour Black, Silver, Blue, Bronze, Orange, Purple or Red · tubeless valves (50 mm, up to 2).

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), SM-RT66 160 mm 6-bolt rotor, 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 (32 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 rims 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. Hope hubs are covered by Hope's manufacturer warranty against manufacturing defects, handled through the Australian distributor. 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.
