**I am republishing my review I wrote several months ago for the M60Forty wheelset that I original posted for the DT Swiss hub-equiped wheels. The wheels I own are equipped with Chris KING hubs but at the time I ordered, KING hubs were a custom build and not stocked by Comp Cyclist.**
I now have several 100 more miles on the M60Forty wheels than I had when I originally reviewed them and I can say they continue to impress me every time I ride them. I routinely go to my hardtail equipped with Stan's Crest and occasionally ride a bike with Stan's Arch rims. While the Stan's rims are solid wheels and I like them, I LOVE the ENVE wheels!! The Stan's are like driving a nice Honda and then, The ENVEs are like THE BATMOBILE!! The ENVE wheels are so fast, so strong and just inspire confidence. I can rail anything without any noticeable flex or give. Perfect.
Why do I insist on KING hubs? They are about 100 grams (of rolling weight) heavier after all. If you have ever ridden KING hubs, you know it is worth a 100 gram weight penalty for the fastest engaging, most durable hubs in the industry. Keep in mind, they do require adjusting from time to time.
My preface: this review is my opinion and not objective fact.
I bought my first mountain bike in 1992...and I have owned several since. This is my first 650b/27.5" wheeled bike but that doesn't make me hesitate when I declare these wheels to be the BEST ever made! I have ridden some fairly high-end mt wheels (Stan's Arch and Crest, Shimano XT, just about everything offered from Mavic) and maybe it is that these are my first carbon rims and/or maybe it is the change in wheel size from 29er to 650b but I suspect it is much more than that...these are ENVE carbon rims. I never knew wheels could ride so nice! Obviously, rolling mass is an area where an upgrade will make a larger impact but the difference between the M60Forty wheels and anything else I have ridden is HUGE! These wheels are SO SO stiff and inspire confidence I have never felt before in over 20 years of riding the mountain. They were easily set up tubeless and roll up to and maintain speed nicely via the Chris King hubs (I had Mike Nelson, ext 4076, special order these. As with all Comp Cyclist reps, Mike is AWESOME!!). I am sure there are plenty of other lightweight options but these are NO compromise wheels! You plunk down the $$ and ENVE WILL deliver the goods!!
If I had to complain about anything, the decals are dinged and scratched easily (signs you are riding right, my friend!) and they are très $$$$. BUT if you can afford them, you can't afford not to ride them! You will not be disappointed!
My quick plug for 650b/27.5": I went from 26" to 29" and now, 27.5" and each have there +s and -s. I agree with many that state 650b is the best of both worlds. Still, I think/hope this size will grow and settle in as the trail/All Moutain standard...and I am sure that my incredible experiences on these wheels (and my Santa Cruz Solo/5010) have a lot to do with the 650b standard. Still, I keep more than one 29er in my fleet and feel it is the best size for racing. For what it is worth...
