A few 12 months and a half in the past, Business 9 launched two new wheel traces for All Highway and Gravel. The transfer got here shortly after introducing their new SOLiX hub line, which was constructed round providing lighter hubs with lowered drag, however nonetheless holding the engagement very excessive.
The result’s a hub with 605 factors of engagement utilizing 5 pawls which are constantly phased and a 121-tooth drivering. That 0.59º engagement appears like so much, and it’s… simply not as quick as their new Hydra 2 hubs with 0.41º engagement. Realistically, although, the 0.59º engagement is far more than you want for street driving, so the decreased drag and lighter weight of the SOLiX hub is an ideal match for the brand new Aero Highway Wheels.
With Gravel and All Highway already accounted for with the SOLiX G and SOLiX SL AR, Business 9 is specializing in quick street driving with the brand new SOLiX Aero Highway assortment.
Supplied within the R35, R50, or R65 (R for Highway), the brand new rims are barely wider with an up to date aero profile meant to match trendy wider street tires. I9 states that the wheels are optimized for 28-30mm tires for the very best aero efficiency, however I’ve been driving them with 32mm tires with out difficulty, because the protected tire vary is listed as 25-35mm.
The primary objectives for I9 with the brand new Aero line have been to supply extra stability in assorted wind circumstances, whereas additionally lowering aero drag and rim weight. Notably, solely the center R50 adjustments in depth, with the earlier center rim measuring 45mm. In comparison with I9’s most up-to-date Aero street wheels, it appears that evidently they’ve met their objectives, claiming enhancements on each rim measurement. In comparison with earlier fashions, the R35 boasts a 3% weight discount and seven% discount in common watt/hr, the R50 is 3% lighter and a couple of% extra environment friendly, and the R65 is 5% lighter and 10% extra environment friendly.
The entire rims characteristic a 22mm inside width (up 1mm from the earlier 21mm), persevering with with a hooked profile for straightforward tubeless setup and improved tire retention. Constructed with 24 bladed metal straight-pull spokes, the spoke nipples are exterior for straightforward upkeep.
Out there with Centerlock hubs solely, the hubs can be found in both customary quick-release spacing (100/135), or the extra trendy 12 x 100/142mm through axle spacing. 4 totally different freehubs are supplied, together with Shimano HG11 or MS-R, SRAM XD-R, and Campy N3W.
Wheelsets begin at $2,265 for the R35 in black and prime out at $2,295 for the R65.

I9 SOLiX R50 Aero Wheel Evaluate
Business 9 set us up with a set of the brand new SOLiX Aero wheels properly forward of the launch date, so we might frontload the miles. I opted for the center R50 as that depth has been my every day go-to for some time now. Quite a lot of my street driving is flat, however then there are many climbs out of the river valleys the place a lighter wheel continues to be welcomed.
On the dimensions, my R50s with tape, valves, and an XD-R freehub checked in at 779g for the rear and 664g for the entrance. That places them at 1,443g for the pair, barely over the 1,410g claimed – which possible means the claimed weight is with out tape or valves.
One in all my favourite points of the brand new SOLiX wheels is how straightforward it was to arrange tubeless. I had determined to make use of a pair of Schwalbe Professional One tubeless tires in 700 x 32mm as my tire of alternative. These have been the identical tires that I’ve been scuffling with to carry tubeless on one other wheelset for a 12 months. Seems, it’s positively not the tire that was the difficulty.
The Schwalbes mounted as much as the SOLiX rims extremely simply, and with out the necessity for instruments. A fast burst from the air compressor seated the tires effortlessly, they usually’ve held air since with none difficulty.
Notably, the identical tires that hardly crammed out to the claimed 32mm on earlier rims now measured 35mm on the SOLiX rims. For me, that was excellent as a result of I wished to run wider tires, and it suits within the body and fork of my bike. However preserve that in thoughts if you’re deciding on your tire width.
The SOLiX wheels really feel like an ideal match for my Why Cycles PR street bike. It’s been a favourite of mine for years, and despite the 32mm claimed tire clearance for the body, the 35mm tires on the SOLiX rim simply match. Notice that my wheels have been despatched with blacked-out graphics from the earlier I9 Aero line, and the manufacturing graphics will match the studio pictures above. Whereas customized graphics will not be supplied by way of I9, you will get customized decals by way of I9’s official companions: Slik Graphics or Groundkeeper.
The hubs have that trademark I9 sound, however it’s quieter and higher-pitched than the Hydra hubs. It’s additionally quieter and fewer aggressive than the DT Swiss freehub on the Roval wheels these changed. Individuals will nonetheless hear you coming if you happen to’re coasting, however it’s not as intrusive.
At this level, I’ve had fairly a couple of rides on the Business 9 SOLiX wheels, together with a couple of that have been very moist. Every thing is rolling simply as easily as they have been out of the field – possibly smoother. My check wheels have the usual metal bearings in them, however they nonetheless spin extremely properly. One of many primary objectives of the SOLiX hub design was to lower drag, and you may definitely really feel that on the street.
It’s at all times arduous to quantify aero enhancements out on the open street, however I can say that the wheels really feel very composed in gusty cross winds. I’ve but to have that hair-raising expertise the place the wind muscular tissues your entrance wheel out from beneath you, forcing you to react and struggle the gusts.
Simply as necessary, the SOLiX wheels have a wonderful journey really feel. Coupled with the added cushion of a tire measuring 35mm, it will likely be very arduous to return to anything. I had the conclusion the opposite day that I’m by no means going to journey a 25mm street tire once more, and actually, 28mm tires will most likely be in that very same class quickly.
You will discover lighter, or cheaper wheels, however there are few on the market that provide this mix of journey high quality, efficiency, ease of use, and the flexibility to make them your personal. The brand new SOLiX Aero Highway Wheels examine quite a lot of bins and are an ideal addition to your favourite trendy street bike.
