Enve SES 2.3 - Rear- InnerDrive Hub - Shimano 11/12

The SES 2.3 is purpose-built for the mountains. Ultra-light, respectfully aerodynamic, and optimized for tubeless tires, the SES 2.3 raises the bar for performance through hilly and mountainous terrain.

NOT FOR OFF-ROAD/GRAVEL USE!

There’s no better option for the uncompromising climber who values performance up and down the mountain than the new SES 2.3. At sub-1200 grams, they’re in a league of their own and deliver a real-world advantage in hilly terrain through their lightweight design and confidence-inspiring handling. 

Modern-day alpinists take their ethos of ‘Fast and Light’ seriously by avoiding unnecessarily heavy gear to get up the mountains quickly while maintaining confidence on the way down. The SES 2.3 subscribes to that same idea in the pursuit of scaling mountains efficiently and providing even more fun and stability on the descent. Paring down from the SES 3.4, it maintains the proven Smart ENVE System design elements of dissimilar front and rear rim depths for handling the varying air flow elements from the front to the back of the bike. 

At 28mm for the front depth and 32mm for the rear depth, the SES 2.3 provides crosswind stability and flatland aerodynamic efficiency to descend confidently and carry speed in the flat valleys between climbs. Utilizing hookless bead tubeless technology allowed our engineers to pull more weight out of this wheelset, tune the comfort, maintain strength, and ensure an exacting rim bead seat diameter to provide the most precise tubeless interface. This wheelset is tubeless and disc brake only. When it comes to the biggest climbs of the Grand Tours or the undulating terrain out your front door, there’s simply nothing faster.

Due to the extremely lightweight nature and construction of this rim, it is not suitable for off-road/gravel applications.

MATERIAL OPTIMIZED DESIGN

We design and build to the strengths of carbon fiber, and there’s no better example of this than the SES 2.3. By using continuously running fibers throughout the rim, tapering laminates, and removing excess material, the SES 2.3 achieves an impressive feat in weight reduction and composites engineering. Additionally, layering fibers in specific orientations achieves zone-specific performance requirements like impact toughness, stiffness, and tire retention.

TUBELESS OPTIMIZED

Tubeless represents the pinnacle of road wheel and tire performance, and the hookless bead design plays a significant role. A hookless rim design allows for machined metal tooling to establish a precise and consistent bead seat diameter that meets the defined requirement by ETRTO. That precision fitment between the tubeless tire bead and the rim’s bead seat ensures air and tire retention.

ENGINEERED FLAT PROTECTION

Most flat tires are caused by one of two things; Intrusion punctures (staples, thorns, glass,etc.) or pinch-flats (potholes, railroad tracks, rocks, etc.). While there is little we can do as a rim manufacturer to prevent punctures, the rim feature called Wide Hookless Bead greatly reduces the likelihood of pinch-flatting. Wide Hookless Bead technology works by providing a blunt surface upon which to bottom out the tire, dissipating energy across a larger surface area and preventing tire damage. This allows you to run the correct tire pressure without the worry of pinch-flatting.

INNERDRIVE PREMIUM ROAD HUB

Featured in all SES and G Series wheels is the ENVE Premium Straight Pull hub, an all-new, 100% ENVE drive mechanism. Oversized steel ratchets are positioned inboard and over the bearings, reducing stress on the axle and bearings while ensuring positive and reliable engagement. Key benefits of the INNERDRIVE™ Premium hub include:

• Weight Savings: The new ENVE INNERDRIVE™ Premium straight pull hub offering delivers 60 grams of weight savings over ENVE’s previous generation hub offering.
• Four Engagement Options: Interchangeable ratchets allow riders to tune their rides for their personal performance needs. Whether it be maximizing efficiency, response, or reliability, we have a solution. Ratchet options include: 40 tooth, 60t, 80t, 100t.
• Consistent Spoke Lengths: The all-new straight-pull hubshell allows for the use of a single spoke length for any given rim diameter, creating an easy user experience for service and maintenance.
• Anti-twist Spoke Hole: To further improve the quality of the wheel build, spoke tension consistency, and to prevent spoke damage during wheel build, an anti-twist feature has been included to prevent the spoke from twisting during wheel build or while riding. 
• Silent Spoke Crossings: The straight-pull hubshell puts space between each spoke ensuring that your ENVE wheelset cannot experience spoke creak.
