BA30 Rear Wheel

CHF 352
Driver Body:

The BA30 is a quality alloy rim designed to withstand a real beating.

This is the rim for high-impact riding when the trails are rough and rugged. With an internal bracing structure, the BA30 has torsional stiffness for directional control in demanding circumstances. The BA30 features a thick bead wall adjacent the tire to resist impact deformation, with a wider, rounded top-edge to reduce sidewall cuts. The nipple/spoke bed is oriented to the spoke direction to reduce weakness caused by bend in the spoke at the nipple hole. The BA30 is made with premium alloy, extruded with an internal brace profile and carefully formed for consistent shape. It is then fusion welded and ground for a strong precise finish. Our fusion welding system leaves a perfect seamless joint that becomes the strongest section of the rim ensuring that your rim won’t split if you impact at the seam. 

The rims are laced to our new R4 hub. The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings.  We're using a tried and tested 4-pawl arrangement with 36 points of simultaneous engagement.  What sets it apart is the large radius that the pawls are positioned on, reducing leverage at the point of engagement. 

We opted for a Chromoly steel axle for stiffness and longevity.  Using steel allows a smaller diameter axle which in turn gives us more room to use larger, sealed bearings (we use USA made enduro bearings).  The rear axle assembly uses thread-on end caps which are easy to service and resist compression from the frames axle (they don’t fall off during trailside repairs either!).  R4 front hubs are available with standard or ‘torque’ end caps and rear hubs are available with XD, HG, or Microspline drivers.  We supply all parts for servicing to ensure that R4 hubs can be maintained well into the future!

The same as I said

The same as I said for the front wheel... So far it is holding up, so the wheel itself seems to be good. We'll see how it does long term. Dropped a star due to issues with shipping and lack of attention to the rim tape, along with a lackluster response to both.

Does the job

I'm pretty heavy and have a habit of breaking wheels. So far these have been fantastic. Rims haven't got so much as a ding and the hubs do what they're meant to. Would recommend to a friend.

BA30 wheels

Best wheels I have ever had. I've had one on my hardtail for three years and it hasn't even seen a spoke key. Also have a pair on my trail bike going strong after a year or so.

BA30 Wheel

I haven’t gotten to ride the wheel yet but it looks solid! I’ll update the review after some park thrashing.

Strong and solid.

This wheels are amazing. I have a pair on my Rootdown and after two years of hard riding they’re still straight. They hold inserts pretty well too. I’ll definitely buy some for my next trail bike.

Super stoked

Bought my BA30 rear laced to the R4 hub over a month ago and cannot be happier. This wheel has exceeded my expectations and is still straight as an arrow and Taking everything I have thrown at it. Very solid set up and looks great on the bike. The addition of this wheel and a BA30 front has made my bike feel very solid on the trails and taking the abuse I throw at them in the park. I recommend this wheel to anyone that has asked.

Solid, no nonsense

The most durable rim I’ve used on a simple, tried-and-true hub that works well and is easy to maintain. Wheels have withstood well over a year of my poor line choice and inadequate skills and don’t look much worse for wear- would recommend.
