Smooth, stable, and snappy.

The ENVE Smart System 3.4 Carbon Clincher Wheelset is the result of a holy union between aero-engineering legend Simon Smart and ENVE Composites working together towards one common goal: producing the best wheelset on the planet. To do this, they agreed that the ultimate wheelset needs to meet specific criteria: an outstanding weight-to-strength ratio, durability, aerodynamic stability, and minimal drag when fitted to a bike. The Smart System 3.4 Clincher Wheelset meets every design goal, and shows what's possible when a wheel is manufactured across the hall from the engineering office.

The ENVE Smart System 3.4 Carbon Clincher is part of the SES series. ENVE used its most sophisticated technology and engineering techniques to create this fast, stiff, and aerodynamic wheelset. The 3.4's aerodynamic design starts with the size differential of the wheels. ENVE accounted for the different behaviors of front and rear wheels, and designed the 3.4s with the front wheel that's 35mm deep and 26mm wide, while the rear wheel is 45mm deep and 24mm wide. The front wheel's shallow profile and wide stance helps decrease drag in windy conditions. On the other hand, the rear wheel's depth decreases drag because stability is less affected at the aft position of the bike. According to ENVE, the 3.4s create a low drag number rivaling many competitors' 50mm- and 60mm-depth wheels.

Outside of consistent aerodynamic performance, the most noticeable advantage of the 3.4 carbon clincher wheelset is its enhanced stability. The 3.4 demonstrates stellar results under the ENVE Stability Index, a series of tests that incorporates the measurement of transient aerodynamics. In the wind tunnel, the front wheel is subjected to quick changes in wind degree at set yaw angles, and the steering torque of user-correction is then measured. The test represents real-world conditions, and surprisingly, ENVE is one of the only non-Formula One manufacturers to conduct it. The 3.4 shape that was developed as a result of these tests ensures predictable airflow attachment over the rim, regardless of crosswind; the linear steering response trumps even the Zipp Firecrest series. In a crosswind, the 3.4 experiences a buildup of side-force equal to the changing angle of the wind, and the predictability prevents the need for rider over-correction.

The Smart System 3.4 Clincher is not only aero, but it's also light, stiff, and strong. The ENVE SES series boasts the highest strength-to-weight ratio on the market, and its due in part to ENVE's patented process of molding in spoke holes, nipple seats, and valve stem holes. Knowing that carbon fiber gains strength from continuous fibers, ENVE routes the fibers around each hole in a 100% intact design. This design allows a lower weight at the spoke face, and adds overall rigidity to the rim. When built, the molded design promotes both higher spoke tension and tension uniformity. Another aspect of the 3.4's light weight is due to ENVE's use of removal bladders during the molding process. While most composite rim manufacturers leave the rim-shaping inflatable bladder in the rim, ENVE spends the time and money to remove it. This time-consuming process reduces rim weight, and makes for a perfectly tensioned wheel build.

The ENVE Smart System 3.4 Carbon Clincher Wheelset uses a 20/24 spoke count and is built with DT Aerolite bladed spokes and DT Swiss 240 hubs.

The ENVE Smart System 3.4 Carbon Clincher Wheelset is available to fit Campagnolo and Shimano/SRAM cassettes. Every ENVE Smart System 3.4 rim is handmade in the USA.

tough wheels

  • Familiarity: I've put it through the wringer

i have used these wheels on very unforgiving roads. every bit of the wheel is as it came. dont flap around too much in crosswind. climbing and descending is with ease

one of the best wheels available

  • Familiarity: I've put it through the wringer

Rode these for the first time this last year and tested them out for about 3 months on a couple different bikes. Although a little heavier than the 1.45's that I had been riding they are incredibly quick uphill. Most of my riding involves going uphill so that is a big factor to me. Next is going back down the hill fast. I got right on these and felt completely comfortable at speed on a windy descent. Handling was phenomenal with the new wider rim size and makes me consider it to be one of my top 3 wheels. I would race/ride these any day of the week. I am a smaller stature rider and think that if you are not as weight conscious that adding a few grams and going to the 6.7 may be an option depending on your style of riding. You can contact me directly with any questions about these wheels or comparisons, I can also help you out on shipping costs - kylebrown@backcountry.com

Best wheels I've ridden. Period.

  • Familiarity: I've used it several times

Buying a new wheelset of this quality is a commitment in money and requires the confidence that you're getting exactly what you want. These wheels continue to blow my mind! Every ride is a completely new experience on the same frame that I've ridden now for more than 10 years. These wheels are simply faster on the flats and on the climbs - both subjectively and objectively on Strava. Not only that, they brake, handle and roll better than any wheel I've ever ridden (apologies to Easton, Mavic and Zipp). The achilles heel of carbon rims has historically been stopping power and on these wheels (coupled with Enve gray, carbon pads) I have better braking ability and modulation than I ever did with my Mavic aluminum rims. Ditch the belief that carbon rims can't brake! Best wheels I have ever ridden in more than 20 years of riding experience. Period. Buy em!

ENVE Wheels -- the cycling equivalent of a Lambhorgini. We get it. We know it. We've had it pounded into our skulls by every reviewer on the World Wide Web. Those reviewers might have also mentioned the strength of the carbon that ENVE uses, the fact that they're an American company or even that ENVE is the original full-carbon component company. What might not have been pointed out, however, is that for the serious cyclist, components are an investment in peak performance. Just like you wouldn't gorge on cookies and ice cream for months before race season and expect to excel, riding anything less than the very best won't earn you that STRAVA KOM on your local pavement grind.

In all seriousness, the Smart 3.4 system isn't only lightweight, quality carbon that could probably withstand most bomb-blasts (and missed bunnyhops over parking lot curbs), but wheels that are stiff, responsive and that come with an unbeatable warranty of 5 years. Yeah, you read that right. 5 years. On carbon wheels? Ka-ching.

The wider, more shallow hoop profile on the front wheel creates a more stable riding experience while the slimmer, deeper profile on the rear rim helps with those pesky aerodynamics. Overall opinon? Kickass. Whether you're a professional athlete gunning for the podium, an off-season trainee looking for the best of the best, or a local hero looking to lose some grams and gain some fun (and Batman-like stealth), I highly recommend these wheels.

Curious as to how the bunny hop ended? Or why I love ENVE so darn much? Or how to buy a set of your very own with customized options? Call me (or email me). We'll chat. 801-736-6396 ext 4768 or abatty@backcountry.com.

Sweet wheels, bro

  • Familiarity: I've put it through the wringer

Smooth, stiff, light, bomber. What else do you need? Yeah, they're pricey, but when dropping more than $2k on any other wheelset, why not get the best? I know the founder of company, I ride with the engineering manager, I've been elbow to elbow in sprints with the head wheel builder. Enve makes such an awesome product, right here in Utah. Its simple, these are some of the best wheels money can buy.

As a Competitive Cyclist employee and bike racer, every opportunity to ride the Enve Smart System 3.4's is a real treat. (Check out the photo for a Merlin Extralight Featured Bike spec'd with these bad boys).

ENVE has put plenty of technical expertise and top quality materials to produce these wheels. Our write-up does a great job at diving into this tech, but for the simple minded (like me) I'll stick to how they actually ride.

The Smart System 3.4 has simply found rolling Nirvana: Stiff, agile and responsive under power, robust and stable at any speed or wind condition, and oh so quiet as they barely make a noise. Any ride on this wheelset is a tranquil endeavor. Braking surface combined with Enve's own brake pads is reliable, even in the rain, especially relative to other carbon braking surfaces I've been on the past.

This is certainly not a budget wheelset, but you're getting an absolutely premium cream-of-the crop product any time you purchase ENVE.

If you have any questions, I'd love to help you out. You can request me on chat, reach me by phone

man, I've ridden so many miles on flats

  • Familiarity: I've put it through the wringer

And not because of the wheels, just because I flat and don't have (enough?) spares. So...sometimes you have to ride the flat tire home. Carbon on pavement, bad idea, but as long as you keep the tire on the rim, the wheels don't care at all. The reviews below state what we all know - the wheels rock, but what they don't tell you is how durable they are. 3 winters' worth of salt and slush riding and probably 100 miles of flat tires, by now, and the wheels have never been trued once. I'm wearing out the hub bearings on the DT240's before the rims.

Worth it!

  • Familiarity: I've put it through the wringer

I've had my fair share of wheel sets, and while I think I would have a set of 6.7s in tubular form as a fun wheel set, it is hard to beat the versatility of the 3.4. Living somewhere with strong winds, it wasn't fun to ride on my previous Reynolds DV46ULs when it was blowing out. I loved the feel of those, especially hammering up our power climbs here, but then most 1100g tubular wheels feel awesome. I didn't want to hassle with that for daily use, so I kept debating what to get before deciding to spend the money and get the Enves. Having looked at Zipps, I was really close to getting the 202FC, but read of issues with the 2013 and previous year hubs. The Enves are stiff, relatively light, handle winds like a champion, and feel faster than the previously mentioned Reynolds. The brake performance has been awesome, and I am very happy with my purchase. It's also nice to know that the Enves are made in the USA and that they have their warranty should any issues arise.

Worth it!

Build quality A+, DT Swiss hubs - amazing, braking (with the ENVE Pads) is extraordinary. These are delicious wheels, treat them with respect or jump them off curbs - they will stay dead true and keep rolling. Confident, no fade braking from 50mph on 15% grades = spectacular handling and overall make for a safer ride :) If you can afford them, go for it :)

Awesome Wheels

  • Familiarity: I've used it several times

I just replaced my Mavic Krysum wheels with these ENVE?s set, and I feel a total different bicycle. I reached 29 mph and kept this speed easy under medium windy condition. No issues with lateral winds and the drag has been reduced a lot.
They are not cheap but, the technology, quality, and the care behind these wheels you will feel on the road.
