What’s new?

We’ve been working on some great new things for the 2015 wheel line. 

All of our wheels are hand build here in Eugene, Oregon and we set ourselves apart by offering a combination of the best technology, quality and craftsmanship in each wheelset we sell.

Road Carbon

Ares4 ES and Ares6 ES –

All new full carbon-clincher models.  A 42mm (Ares4 ES) or 60mm (Ares6 ES) rim depth option with a retail of just $1849 a set, these models feature our Delta Rim Technology that not only increases their aerodynamic benefits, but also creates an around more durable and overall handling performance wheelset.

58RSC –

The 58RSC  rim profile has been upgraded to a 22mm wide profile, improving aerodynamics, stiffness and the overall ride feel.

TdF4SL –

The TdF4SL rim has been updated, improving stiffness by 15% as well as adding additional impact resistance. Also check out the TdF4SL Disc option, for running road disc.


Road Alloy

Aspin SL Disc and Aspin 650c –

Now you can choose our Aspin SL wheelset with a disc compatible hub.  Using the technology of the Aspin SL combined with our XR road hubset, the disc brake compatible Aspin SL Disc looks stealth with its US made disc brake specific all-black rim.

We’ve also added a new 650c wheel size, with the new Aspin 650c option.

You’ll also find our new in-house US made rims on the 2015 Aspin and Aspin SL models.

Echelon SL and Echelon –

Stepping it up on our already popular Echelon SL and Echelon models, they now feature our in-house US made alloy rims. 


Mountain / Gravel adventure / Cyclocross

Ralos CXC –

We know there are more and more 27.5” bike choices now on the market, last year we brought you options in the alloy Ralos and Rage models for a 27.5” wheel size, this year we’ve stepped it up with a 27.5” wheel size option on our popular carbon Ralos CXC.  Engineered to fit many configurations, choose thru axle or QR, 1x11 freehub or even our lefty front hub option.

We also updated the Ralos and Rage models to our XST+ hubset, to include a CNC’d titanium freehub body.

4CX Disc and ECX Disc –

An all new mid-price disc brake option, the ECX Disc can be built on an alloy clincher or tubular rim option.

We’ve also updated the 4CX Disc rims to increase stiffness and durability, ride them, race them, simply enjoy the ride!

Thru axle on your cross/ gravel bike?  No problem, we’ve updated our disc hubs to be convertible between QR or thru axle and we’ve added 11sp compatibility.
