Industry Nine is at it again. This time, they’re focused on the world of road and gravel with a new product line called SOLiX. Impressively, I9 claims this is their most technically advanced hub system to date – offering a massive 605 points of engagement!

Industry Nine SOLiX wheelset — What is it? 

The new SOLiX line arrives in two wheelsets with different personalities. They have two distinct hubs and spoke configurations designed for road, gravel, or whatever you ride. Builds are customizable, but I9 puts them in two pathways: SOLiX SL and SOLiX G. 

AR40 SOLiX Gold

The SOLiX SL is the race/lightweight focused of the bunch, and the SOLiX G is for the off-road adventurer.

SOLiX Freehub face

The SOLiX wheelsets are both built around the i9s SOLiX hubset. The new hubset is a continuously-phased five-pawl freehub with a 121-tooth drive ring. It offers 605 contact points, translating to an ultra-fine .59° engagement. That’s not quite the 690 POE and 0.52º of the I9 Hydra hub system, but it’s far more than we typically see with gravel and road hubs.

I9 has also has an all-new hubshell design meant to make the hubs more durable and faster when coasting. All of these pieces together add up to what they’re considering their most technologically advanced hub system yet.

The SOLiX SL is the lighter and more road-focused wheel. According to the brand, the SL is the “highest-performing lightweight road and gravel race wheels from i9.” The new wheelset features a slew of high-end build features and a respectable weight of 1270g for the carbon rim build.

Riders looking for extra flair can select 11 anodized hub colors and nine spoke nipple colors from the custom wheel designer.

The SOLiX collection also offers the most adventure-worthy and fully customizable gravel wheel from i9.

Thanks to tech borrowed from the i9 MTB realm, these wheelsets excel on backcountry and gravel routes. The hubs and spokes are available in 11 anodized colors, inviting riders to configure their dream wheels via custom wheel designs.

AR40 I9 Rim

All New i9 AR40 Rims Hooked Rims. 

There is a lot to say about hooked and hookless rims right now, and i9 is staying hooked in their newest line. Why? The hooked rims permit higher tire pressures, mitigating blowoff risks associated with hookless rims and allowing for a lower bead wall height than hookless road rims. 

The AR40 rim features a 25mm internal width and a 35mm external width, providing a nice perch for tires ranging from 28mm to 34mm and offering aero advantages and an airfoil shape. I9 claims this design extends its aero benefits to tires up to 40mm wide, making it versatile for any terrain and tread choice.

The design team at i9 created a 4mm wide bead wall to reduce the risk of pinch flats. This design hopes to disperse impact force over a broader area. Lastly, the high-impact strength of the layup is tailored for gravel applications, reinforcing the wheel’s ability to withstand impact forces and sustained abuse on rough roads and trails.

SOLiX Hubset

At the heart of SOLiX Hubs is a continuously-phased five-pawl freehub seamlessly

​integrating with a 121-tooth drive ring with a whopping 605 points of contact, translating to an ultra-fine .59° engagement. Crafted from A2 tool steel using precision wire EDM cutting, the pawls and drive rings are engineered for maximum durability.

Industry Nine reduced pawl rotation and spring pressure, optimized drive ring diameter, and changed the contact seal layout, reducing resistance and freewheeling noise. This all culminates in faster engagement, lower friction, and enhanced durability.

SOLiX Hubset Details:

  • Hole Count: 24| 28
  • Engagement: 605 P.O.E or .59 degrees
  • Axle Specs: 12X100 Front | 12X142 Rear
  • Freehub Body : SRAM XD-R | Shimano HG | Shimano MS-R | Campagnolo N3W
  • Weight: Front 110g | Rear 223g
  • MSRP: $695 pair

Will these axles last longer than the MTB ones? You could argue the bending moments will be lower for gravel riding due to less frequent low cadence power. But if these hubs work the same way as the others I’d recommend to stay away

605 POE? Seems like overkill for gravel. I run a 54t 240S and even that seems like too many sometimes. There’s gotta be a significant amount of drag with such a high number of engagement points huh?

This. I have several sets of I9 hubs for road and gravel. And with 60 PoE they have noticeably more drag than my DT Swiss 240s (36 PoE) and White Industries CLD (48 PoE) wheels. I have their Hydra hubs on my mountain bike, and the instant engagement is nice. But I’m not really seeing the need for road and gravel riding.

Lotta drag, for one point of engagement at any given time. No thanks. Profile elites for me .

Their location in Pisgah North Carolina fuels their approach to product design for sure. For people who ride the champaign gravel of an area like the midwest this is definitely overkill. Pisgah is a different animal all together and I think these would be great for that application. A lot of people would probably be better off riding Pisgah gravel on a mountain bike, it’s really that nasty. The good stuff anyway 🙂

weird to name the rim the AR40 when Race Face has been making an AR rim for a long time. There is even an AR40.

Light Bicycle also has an AR line, but in 35/45/55 depths. Maybe it’s like adding SL or SLX to something, I dunno. I’m in IT so we just call everything next gen.

Industry Nine hubs may not be perfect, but when you are actually shopping for wheels, they always come out as a high value. Price is good. Replacement parts are easy to get, fair priced, and easy to swap. The product line is not confusing (which makes resell possible). I also think the aluminum spokes are underappreciated. Most spokes break at the nipple, so make breaks are prevented with them.

pawls and only o-n-e pawl transferring the power thorough minuscule teeth on the drive ring side does not sound very appealing from a tech or durability point of view. no thanks
