If you’re riding hard in rough terrain, casing occasionally (or often), and don’t want to think twice about your rims holding up, the BA30 is the rim for you. It delivers the confident feel of a stiff platform with just enough give to keep things tracking smooth. It’s made for riders who charge hard and expect their gear to hold up.

With the v2, we’ve built on the original strength-focused design and made it even tougher. A refined beadwall and sidewall design delivers 20% more impact resistance than its predecessor. The deeper rim section resists flat spots more effectively, while a wider central channel makes tire installs and trailside fixes easier. And thanks to optimized shaping and smart material redistribution, we’ve achieved all this with zero increase in weight.

Our most aggressive alloy rim, proven on the world’s roughest tracks is laced to our brand new R6 hub. The R6 uses a 7075-aluminium axle with press on end caps and a larger diameter ratchet ring interfacing with 6 pawls. These interact in 2 sets of 3 resulting in 96 points of engagement. The alloy axle aids stiffness the use of press on end caps prevents over preloading the hub bearings or ends caps backing off in use. One of the design goals was to minimise friction. Refining our axle tolerances and designing a single lip freehub seal helped us achieve our friction goals while maintaining the reliability our hubs are known for.

☛ High Impact Resistance
Reinforced beadwall and sidewall design provide exceptional durability on rough, unforgiving terrain.

☛ Deep Rim Profile
Reduces the chance of flat spots from hard hits and harsh landings.

☛ Easy Tire Changes
A wide central channel makes mounting and removing tires smoother, even trailside.

☛ Optimized Strength-to-Weight Ratio
Strategic shaping and material placement deliver serious toughness without excess weight.

☛ Premium 6069-T6 Aluminum Alloy
Chosen for its superior strength, resilience, and long-term performance under stress.

☛ Fusion-Welded, Precision-Ground Seam
Creates the strongest part of the rim, ensuring perfect alignment and airtight tubeless setup.

☛ 1 wheel.

☛ Purpose-Built Alloy Selection
We use 6069-T6 aluminum for its elevated yield strength and impact tolerance compared to more common alloys—ideal for aggressive trail and gravity use.

☛ Fusion Welded for Structural Integrity
Each rim is joined with a full fusion weld, then ground smooth to ensure a seamless junction—stronger than a sleeve joint and guaranteed airtight for tubeless setups.

☛ Precision-Engineered Extrusion
The rim profile is optimized for a balance result, fine-tuned to deliver stiffness where it’s needed and compliance where it counts.

☛ Controlled Material Redistribution
Rather than simply overbuilding, we strategically adjusted the rim’s geometry to reinforce critical areas without excess mass—keeping weight down and performance high.

☛ Consistent Tolerances and Finishing
Post-weld machining and finishing ensure that every rim is true, cleanly aligned, and consistent from batch to batch—ready to mount and ride straight from the box.

☛ Designed for Longevity
From alloy selection to structural layout, every aspect of the BA30v2 was engineered with real-world durability in mind—not just to survive big hits, but to keep performing ride after ride.

Rim FAQ's

We have made several big improvemments while developing the R6. Most notably the POE goes from 36 to 96, which you will instantly notice when ratcheting up nasty climbs.

We have also done a lot of work on the bearing tolerances and sealing to create an incredibly free spinning hub.

The v2 has been refined in several key areas while maintaining the same weight. It has a 20% more impact resistant sidewall, with re-distributed material for more vertical resilience and increased lateral compliance.

We have increased the bead wall thickness for increased pinch flat protection, as well as making the central channel wider for easier tire installation.

They both use our top end alloy with a fusion welded seam-ground join, and have a 30mm inner width.

The main difference is the BA30 has some extra internal bracing, making it stronger and a bit heavier.

If you're really on the fence, run a Phase on the front and BA on the rear.

The Phase and BA are fusion welded, and post ground which makes the join the strongest part of the rim!

The Ally is pinned at the joint, which is more simple and less labour intensive, but not as strong. The Ally is also slightly heavier as the alloy used has slightly less strength than that of the BA and Phase.

Wheels come pre-taped with tubeless valves installed.

All you need to do is install tires and sealant.

Our wheels are pre-stressed and ready to ride out of the box.

However, like all wheels there is a bedding-in period, so be sure to keep an eye on spoke tension after the first few rides.

Provided the rim does not have a crack, you can use an adjustable wrench to gently bend it back to help your tyres seat properly. Use a rag or an old inner tube to prevent scratching your rim, and be careful to avoid puncturing your rim tape!

You'll likely need to adjust spoke tension if your wheel has taken a hit hard enough to dent it.
