Cross-country dominance.

Carbon wheels make a lot of sense on 29ers —the larger-diameter rim is inherently less stiff than its 26 or 27’5in counterparts, and the extra stiffness of a carbon rim contributes massively to the overall stiffness of the wheel. ENVE’s M50s, a more trail-friendly version of the long-running XC rims, deliver stiffness in spades, but are tuned to provide a little bit more "give” vertically, so that you get the benefit of the stiff rim when you need it, but it doesn’t beat you up the rest of the time.

The M50s are 21mm wide, internally, which is about 3mm more than the XC rims. This translates into a marginally wider tire, but more importantly, more of the tire’s tread on the ground at any given time. Between this and the rim stiffness, you’ll get experience a "cornering on rails" feeling.

M50s on the Niner Air 9

M50s on the Niner Air 9

ENVE 50’s are nothing short of amazing…overall ride, hard cornering, tracking, ability to accelerate, overall speed….I’ve ridden no equal in 25 years of hard core mountain biking. Compliant, stiff, durable, lightweight….still trying to figure out where the compromise is (well, wallet I suppose….). Never drink great wine or a great Scotch, everything else will pale in comparison and will disappoint. Add to this: never buy ENVE wheels….this too will ruin you and you’ll never settle for riding anything less.

PS - call Virginia @ 801-736-6396 extension 4756 (or use the 800 number)...she was super helpful, incredibly responsive, and extremely knowledgable when looking at options for this Niner Air 9 RDO and ENVE custom build. I'll never buy or build another bike without working with her!

game changer

  • Familiarity: I've used it several times

I built up a nice new XC race bike and skimped on wheels to save some money. Looking back I'm glad I did because then when I put the M50 on this week I could see that they were worth every penny. I can't say that there is a huge difference sometimes between products, but the difference between these and my "starter" wheels was night and day. They were fast, confidence inspiring, not to mention light. I can't ride anything else now. if you have questions on the M50 feel free to contact me directly

Light, Stiff, and Strong

  • Familiarity: I've put it through the wringer

These wheels are some of the absolute best XC/Trail options on the market. Definitely a light weight, stiff, race wheel that you can ride every day on. Would also make an excellent gravel/CX wheel with the addition of a road 11 speed freehub body. If you have the means to spring for these wheels, I'd definitely recommend it.

  • Familiarity: I've put it through the wringer

I have used this wheel for both training and racing. I have ridden it on hardtail and full suspension bikes. Simply put, this wheel has no equal. I have ridden and raced other carbon and high-end aluminum wheels. You either have to sacrifice weight, durability, or comfort. Those trade-offs are a thing of the past with the M50. And a very generous 5 year warranty should put any durability concern to rest. Ride this wheel hard and don't worry about it. You will be faster.

Note: I have put a large variety of tires on this bike. Tubeless ready or not doesn't matter. Every tire I have tried seals up well and mounts easily.

stiff and light

    This is an awesome wheelset! Just picked up a Yeti that was spec'd with these and I'm extremely satisified. Very stiff and light weight . They are ideal for XC racing but durable enough to be an everyday wheel as well. If you haven't experienced carbon on the trail its a very unique feel that will have you instantly sold. Highly,Highly recommended!

    What is the actual weight for the 6 bolt IS hub version?

    Best Answer

    Hey Eric, these wheels with the 6 bolt weight 1421g. If you have any other questions you can shoot me an email at Cheers

    Will this setup fit a Niner Air 9 RDO?

    Will this setup fit a Niner Air 9 RDO?

    Hi, I run these wheels on my Niner Air 9 RDO but the stock options available here won't work with rear quick release. But you can give Enve a call and ask what it would take to convert these hubs so they'd work with you Niner. It's worth it for such a killer frame and wheel setup.

    The best way to set these up for QR is with DTS0029 and DTS0008 (only works with 6 bolt option). This uses the solid thru bolt for added stiffness/ performance.
