Venn 2430 SL AM Carbon MTB Wheelset

The AM and the XC come out of the same rim mould, so the profile, the 30mm internal bed and the 36mm external width are identical. The difference is inside the wall. The AM carries additional Torayca prepreg through the zones where a rim takes impacts, laid up to a schedule validated at 125 joules against the XC's 100. Publishing both numbers is deliberate: an impact rating is measurable and comparable, where terms like 'enduro-ready' are not. The extra material costs 100 grams, and it is placed rather than spread.

A 24mm deep rim is shallow on purpose. Depth buys nothing aerodynamically at trail speeds, and a shallower wall lets the rim flex slightly under square-edged hits rather than transmitting all of that energy onward. The bed is hookless throughout, which removes the thin hook lip at the rim edge and allows the sidewall to be laid up thicker exactly where impacts land. Run tubeless tires that the tire manufacturer approves for hookless rims, and observe their published hookless pressure ceiling — for all-mountain pressures this is never the binding constraint.

Venn 2430 SL AM Rim Profile Technical Drawing

Our road wheelsets use carbon aero blade spokes, because tarmac rewards near-zero elongation and a narrow profile through the air. Off-road the problem changes. Impacts arrive suddenly and from angles a road wheel never sees, and what the wheel needs is a spoke that gives a little and returns rather than one optimised for stiffness alone. Pillar PSR 1420 is a stainless bladed spoke that does that, and it is field-serviceable in a way proprietary spokes are not.

The 2430 rims use an optimised layup of genuine Torayca T700, T800 and T1100 prepreg, the same material family and approach as the Venn 500 road rims. Different fibre grades do different jobs: higher-modulus material where stiffness per gram pays, tougher higher-elongation material through the impact zones. Naming the prepreg matters because it makes the material properties a known quantity rather than an unverifiable claim, and it means the layup is engineered around real numbers instead of a target cost.

Both 2430 wheelsets share a rim mould, a 30mm internal bed, the same Pillar PSR 1420 spokes at 28/28, and the same Boost hubs. What differs is the layup and its rating. The AM is rated to 125 J and weighs 1290g; the XC is rated to 100 J and weighs 1190g. The 100g between them is material placed where the rim takes hits. Choose the AM if your riding involves sustained descending, rock you cannot always avoid, and terrain that tests a wheel rather than a rider's fitness. Choose the XC if your days are decided by climbing and acceleration and you can generally pick a clean line. Neither is a lesser build; they are rated for different work.

- Rim Depth: 24mm - Internal Width: 30mm - External Width: 36mm - Rim Bed: Hookless (tubeless) - Impact Rating: 125 J - Spoke Count: 28 Front / 28 Rear - Spoke Type: Pillar PSR 1420 stainless bladed - Front Hub: Boost 15x110mm - Rear Hub: Boost 12x148mm - Hub System: 36-tooth ratchet - Freehub: Shimano HG, SRAM XD or Shimano Micro Spline - Bearings: Sealed steel - System Weight: 1290g +/- 30g - Finish: Matte, no clear coat (optional UV decals) - Material: Genuine Torayca T700 / T800 / T1100 prepreg

All-mountain and enduro riders who descend hard on terrain where a clean line is not always available. The 125 J rim rating is the reason to choose it: it is validated to absorb more impact energy than the XC layup, at a cost of 100 grams. If your riding is decided on climbs and you pick your lines, the 2430 SL XC is the lighter answer to that question.

The wheelset weighs 1290g +/- 30g, quoted for the pair rather than as a single rim figure. For a 29" all-mountain wheelset with a 30mm internal bed, 28 stainless spokes per wheel and a 125 J rim, that is a light figure rather than a heavy one.

It is the impact energy the rim is validated to absorb in our test programme, in joules. The AM is rated to 125 J and the XC to 100 J. We publish both because an impact rating is measurable and comparable in a way that words like 'enduro-ready' are not. Higher is tougher, and it costs weight.

No — the extra material is placed, not spread. Both rims come from the same mould with the same 24mm depth, 30mm internal and 36mm external dimensions, and both are laced 28/28 with the same spokes onto the same hubs. The AM carries additional Torayca prepreg through the zones where a rim actually takes impacts, which is what raises the validated rating from 100 J to 125 J. The 100 gram difference is concentrated where it does work.

The 30mm internal bed suits 2.3in to 2.5in tires for all-mountain use, holding the casing at close to its moulded section so the tread stays square and the sidewall is properly supported at low pressure. It will run narrower or wider than that, but within this range the tire behaves as its designer intended.

Yes, the bed is hookless. Use tubeless tires explicitly approved by the tire manufacturer for hookless rims and stay within their published hookless pressure ceiling. All-mountain pressures sit far below that ceiling, so in practice it does not constrain you. Going hookless lets us delete the thin hook lip at the rim edge and put that material where impacts land.

The 2430 SL AM is built exclusively to Boost spacing: 15x110mm front and 12x148mm rear. The rear hub takes a Shimano HG, SRAM XD or Shimano Micro Spline freehub body, selected at checkout. There is no non-Boost option, because the wide rim and large tire are exactly what Boost bracing angles exist to support.

Yes. They are tubeless-ready and ship with tubeless tape and valves. On a hookless mountain rim tubeless is the intended setup, and the 30mm internal bed seats a modern tubeless casing securely.
