The Ally is our latest rim offering and is the workhorse of the fleet. Building off the BA30 and Phase30 design, the Ally offers the same robust beadwall and 30mm bed but in a pinned construction helping to keep the cost down.

The Ally shares the same cavity construction as the Phase30, with symmetric nipple drilling, designed to get you rolling on a budget.

The rims are laced to our 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 supplied with standard 'non-torque’ end caps and rear hubs are available with XD or HG driver bodies. 

Use code: WheelieGood to receive $50 off when you buy a front and rear wheel.

☛ Rear wheel comes with your choice of XD, MS, or HG driver body
☛ Front wheel comes with Non-Torque endcaps as standard
☛ Torque (Rockshox) endcaps can be purchased additionally

Great dirt jump wheels

I wasn’t able to leave a review under the Ally 26 wheelset, but I have ran the same set on my dirt jumper for the past 3 years and have had no problems. The hubs also have very good engagement, whether it’s the wheelset with tires or the rims, the price is unmatchable!

Amazingly durable

Have had this rim front and back for 2 years now, and I'm extremely impressed with the durability, I haven't had to touch the front rim at all, and it is perfectly true. I recently rode directly into a tree at a higher speed than j would really like and the rim is totally fine, no issues whatsoever! It took me crashing and blowing up my back tire on some rocks to put the smallest little wobble in the back rim, until that point it was totally true.

At this price point you really couldn't get a better rim! Will definitely be coming back to Chromag for my next rims when these ones are finally done

Great Value!

So I bought budget rims to replace the sad, thin, and garbage wheels that came on my bike (only 19mm!!!). These are budget rims and I expected them to still flex a little bit(I ride a 29er), but nope, almost no perceptible flex. I am heavy (120kg) and hard on my bikes but; under braking, hard landings, or hitting huge rocks the wheels do not flex at all.

For reference: Deore XT hubs 9X100 front and 9X135 rear.

Best value rims on the market!

Can't beat the quality of these rims, especially considering the price. If you are looking for a durable rim without breaking the bank, these are it.
