Easton’s additions were small but important, rounding out the line with modern sizes, finishes and graphics, plus a couple new items…mostly for the road We also took advantage of an unassembled E100 wheel to check out the full carbon spokes and new hubs that make up the incredibly lightweight 1,050g tubular wheelset.

Above, the Haven and Havoc wheels both gain 27.5″ options for alloy (both) and carbon (Haven only) rim models. Spec sheets and more, plus all the rest of the goods, below…





The new EC70 SL carbon stem brings light weight down a price point. It comes in at 140g for a 100mm option. They have 6º rise and lengths ranging from 60mm all the way up to 130mm. Retail $139.


The top level EC90 SL parts get updated graphics, more consistent with the rest of their branding.


2015 Easton EC90 Aero 38 SL aero road bike wheels for clincher tubular and disc brakes

The EC90 Aero 55 SL wheels were announced last year and the tubulars have been available for a bit. The clinchers, however, just started shipping recently.

Joining them is a new, lower profile EC90 SL 38, which gets a 38mm deep rim but the same aero rim profiles and Echo hubs. Even better, both the clincher and tubular will have disc brake versions. Those will be disc specific thanks to a different resin in the rim and lack of a brake track. Rims are 28mm wide, 18mm internal, and are laced 20 front/24 rear, all two-cross. The hubs are convertible to thru axle front and rear, including 12×135 and 12×142 out back. Weights are:

  • Clincher: 1570g
  • Tubular: 1175g
  • Clincher Disc Brake: 1610g
  • Tubular Disc Brake: 1250g


Easton turned a few heads last month with the introduction of their all-new E100 wheels. They’re tubular only and utilize a nearly all-carbon construction with spokes that can be tensioned like normal, trued and even replaced. Here’s a visual on how they managed that.


A large carbon bulb at the end of the spokes looks normal enough, but it’s inside the rim that shows how they build it.



The spokes are pinned onto and sandwiched between carbon fiber rings.

It’s slightly different on the drive side rear, where the ring they’re attached to slots onto the hubshell and is bolted into place.

This design allows one side of the spokes (as a whole) to be replaced in the event of a crash while also allowing the wheels to be trued or repaired. There’s not too many carbon wheels out there that can claim all that and come in so light.

I’m guessing if you have to ask, you can’t afford holds true here?

I got a sneaky feeling they are not “pinned and sandwiched” but over-molded.

Maybe race face can make better wheels with Easton, than Easton could.

The correct weight for the ec90sl tubeless rim brake clinchers is 1,473 grams, not 1,580.
