Riding is believing.

While the internal width of the standard model is already impressively wide, the M70 Thirty HV 27.5in Boost Wheelset bumps the rim walls out even further. The internal width goes from 25 to an almost comical 36mm to allow for maximum volume while running 2.4 and 2.5in tires. This added volume combines with the outsized Boost hubs to make for a ride that's smoother, stiffer, and — courtesy of ENVE's unrivaled carbon can-do — more lightweight and responsive on climbs than any DH-inspired all-mountain and park wheelset has any business being. But here it is. If it sounds too good to be true, we can only respond that riding is believing.

The 27.5in M70 Thirty rim weighs a claimed 453g, making it slightly heavier than its predecessor, ENVE's AM rim, but the payoff of a wider tire bed and more durability is well worth it. Part of the strength increase comes from trading in traditional bead hooks for a redesigned, hook-less bead, which is both lighter and more impact resistant. The internal width on the HV model is so exaggerated that you can almost fit the non-HV M70 Thirty rims inside of it. That means more tire volume for greater cornering stability and more rubber on the ground at any given time.

The rim tells most of the story, but two facts are worth stating. First, they're hand built in Utah to exacting standards for the longevity you’d expect out of a class-leading wheel system. Second, those big, bruising, Boost hubs make for stiffer tracking up front and yet more improvements in responsiveness out back. These wheels are almost never caught on the back foot, even while navigating sharp switchbacks. On a climb. Across rocks. The small engagement angle of DT Swiss' 240 hubs also help clear rocky cruxes and make for a wheelset that may very well outlast your next bike.

Unanswered Question

Can you state the weight of this wheel set? Also, what spokes are used? Thank you.

Totally awesome!

  • Familiarity: I've used it once or twice and have initial impressions

Just had my first ride on these guys today. What a difference! I felt like I could motor uphill a little bit easier because of the stiffness and the lower rotating weight. I'm fat and slow so I had time to think about that. Downhill was awesome too. I don't feel like I got bounced off line or any of the other complaints I read about in the online reviews. The ride was not harsh at all. I felt as comfortable or more comfortable on these guys. I definitely could track better in bermed turns and felt more solid and in control at my little jump park. I'm looking forward to getting more time on them.

I ride a 2016 Santa Cruz 5010 C. I upgraded from the stock alloy 24mm internal width rims. Running 2.4 maxxis highroller 2 front and rear. I did 20psi front and 25psi rear. I'm about 240lbs with camelpack and am not fast or elegant with my line selections (though I felt a little more of both today).

I agonized over mounting these or sending them back because they are pricey and conspicuous. After a week of looking at them in box in my living room, I'm really glad I mounted them and ran them. I read every review and comment board available about these things and just decided to take the plunge.

Like Ferris Bueller says, "if you have the means, I highly recommend picking one up."

hey there is this the wheel set with the new 'rim tape' to eliminate pinch flats, or is that why they are so heavily reduced???

Yep, they’re the version before the newest M730/M735s so they will not have the protective rim strip.

Are these 28 or 32 spoke wheels?

I had the same question, they told me over the phone they only stock the 28 spoke versions as ENVE doesn't make large quantities of the 32. From what ive been told the difference in stiffness/strength is only about 15-20%, and given how strong they are already you wont gain any benefit unless you're doing serious downhill riding.

Competitive Cyclist, you have your information wrong.

You claim "The internal width goes from 25 to an almost comical 36mm to allow for maximum volume while running 2.4 and 2.5in tires."

The regular M70 has an internal rim width of 25mm. The M70HV has an internal rim width of 30mm--not 36mm as you describe. You need to check your copy and update this post.
