Thanks Lars for the detailed explanation, it is appreciated.
I think i’ll keep my order on the 6.7, i prefer the deeper look as well on my XL frame. As far as the 28c if they are just a tad over 28mm installed i’m still inthe 105% rules and ENVE states that the 6.7 are optimized for 27-28c. From the tire pressure calculator, the difference suggested between 4.5 and 6.7 spec are about 2 psi which might be negligible. But from my Black Inc to the 6.7 i have a 10 psi difference been wider and hookless. That 10 psi should be i think noticeable.
Did you rode the new 3.4 yet ? It could be a good second set of wheels from time to time if i go on a climbing trip.
What is your custom built hub ?
Yeah, that’d definitely be more noticeable than the watts gained in aero, and the weight difference (especially the latter is very unlikely to be noticeable).
No, I haven’t. Having both the 4.5 and the ZIPP 353 (which I use for gravel), they just didn’t make any sense. They are very likely a great set of wheels, but I went all in mega light with the 2.3 rims on Extralite hubs.
Tactic Racing TR01 (aka the Princeton Carbonworks hubs). The lightest disc brake center lock hubs I know of.
Thanks man, appreciate your input. Did you ever tried the 454 NSW new generation ?
Damn those Tactic Racing hub are 1300$ 
!
Never tried the 454, neither gen. I don’t expect any magical things of them, so they are likely similar to other 60mm ish wheels.

On the road so no can do. You’re not touching the carbon rim with at any point with the driver or whatever you want to use. Basically just pushing the bead away from the lip enough so it pops away. I couldn’t do this by hand. Just needed something with a small surface to get leverage. My Pedro plastic irons were too big…Sorry I can’t explain it better.
As usual @Power13 gets it. Yeah my plastic Pedros where too thick.

I feel relief knowing that I struggled so much one time that this was my solution as well. The tire was dead and had been seated tubeless for about a year and 3500 miles. Upon retaping the rim I managed to blow it up because I messed up the tape job. Enve covered it but that was a bad night.
You guys still using brute force? I made a special hose and fill my tubeless tire with WD40, and then it slides right off the bead 
Don’t try that at home LOL.

The Specialized 2Bliss RapidAirs that I had stuck on my Foundation 65s were really stuck. The tires had been on a full season and had been flawless, but they were wearing so I needed to get them off. All the regular methods that I use with all my tubeless setups wouldn’t budge these. Usually putting the wheel on the ground and stepping on the tire with a rubber soled shoe is a good last resort to pop the bead, but no such luck. I ended up using a combination of a small hobby scissor and a surgical scalpel to cut the tire and final get the bead free. As I got the last bit of the bead cut, it pop free like it was under a lot of tension.
Along with the Enve Foundation 65’s, which have been really great and a steal at the time I got them on sale for about $1000, I also have a set of 3.4 ARs. The 65’s are better at holding speed and my go to for long flat training days. On hilly days, or days where it might be really windy or I’m expecting rougher roads, the 3.4 ARs are my go to. I do an annual 2 week camp in Maui in January and the 3.4 ARs are ideal for that terrain. I tend to run 28s on the Foundation 65s and 30 or 32s on the 3.4 ARs.
The new 4.5 really would probably split the difference between these two and be a bit of a quiver killer.

For the cream sidewalls I’ve needed to use the iron or driver to unseat. With the black sidewalls just by hand. Both can be installed easily by hand. But, I do a lot of zone 2 so…

Hi there, i got the new enve 3.4 two weeks ago, and i too have the problem of front wheel leaking air even after injecting the sealant, just want to ask how did you solve the problem i assume the problem should be solved by now :)) thanks for the help in advance, a little background info, i paired with 27c enve ses tyres on them which measured 28 instead of 29 as they claimed to be.
Such a bummer that i crashed on the first day of trying the new wheel with new tyre combo, basically just over-cooked a 90° corner which i road pretty much every day, after crashing and back home i noticed the air-leaking problem, not sure if that’s the cause or the consequence of the crash, anyway now still trying to debug the problem and lost all my confidence on the corner, i even feel like the tyre is sliding on me even when i’m braking on the straight line if i brake a little harder than normal.
I think the difference in feel is likely due to a combination of stiffness and susceptibility to wind. I don’t have Enve 4.5s, but I have similarly specced wheels from 3T. They are super stable in the wind, I don’t feel any steering input from crosswinds. Perhaps the 6.7 are different?
I un-installed tire and tape, did 2 new runs of tape with a different, a little more malleable tape (Tesa) and now they loose 1 PSI per day if at all. It’s crazy 
The 6.7 are a little more susceptible to cross winds of course. But still really really good

So you actually think it is the tape problem? After almost 2 weeks of fiddling, i am almost about to file a complaint to enve support, in fact that’s i’m intend to do, to give them a call to see if there is any defect of the rim, but yours seems in a really good condition though. What tyre are you running? I found out it is so hard to install the enve tyre on the new enve wheelset, i need to use the tyre lever to even pull the first side of the tyre in let alone the second side.
I have run ContinS TR and Spesh 2BR without leakage.
Did you use extra tools/gimmick to seal the tyre? I have two extra wheels, one of them is the previous gen enve 3.4, i could seal them with my normal floor pump, but with the new enve wheelset, i couldn’t seal at all myself and ended up going to the car repair shop to get it done, it seems impossible to seal once the tyre are on the middle concave channel, it just doesn’t hold air at all… what’s your experience?
My n=1: I had the same problem setting up the SES 6.7s I purchased at the end of last year, and it was the tape. The rear wheel held air just fine, but I couldn’t get the front wheel to hold air for long enough to confidently go for a ride. I removed the sealant and re-taped the rim (again, with the supplied ENVE rim tape) and it worked the second time around. There wasn’t any obvious problem with the initial tape application, as far as I could tell, but it was also my first time applying rim tape.
I didn’t use any extra tools/tricks beyond the standard recommendation of wetting the bead with some soapy water and inflating the tire with air to seat the bead before adding sealant. After a few rides both wheels hold air even better. I was initially losing ~5-6 PSI overnight, but now I lose ~2-3 PSI at most.
Edit: I’m running 28mm GP 5000 S TR tires on my SES 6.7s and using the supplied ENVE rim tape (26.5mm) and valves.

Hi, that is really informative.
1.About the air leaking issue, you clearly took a way smarter approach than i did, i was too excited to try the new wheel mainly due to the big difference enve has made to their new gen 3.4 ses compared to my last gen enve 3.4, so i ended up crashing on a fast corner, now after taking a few gentle rides here and there with the air-leaking persists, i have noticed the air-leaking problem becomes minor than before now just as you described, in other words, it seems like it becoming more stable, i will see what happens in the next few days.
2.About seating the tyre, i didn’t wet the bead with soapy water, i just pump the tyre straight with the floor pump, my problem is that because the middle channel is so deep and when i was installing it, two sides of the bead are really “sit” in the middle channel, it just didn’t held any air at all from the initial pump so i ended up going to the car repair shop using the air compressor to seat the beads. I’m not sure whether you have tried it before without the soapy water cause i am curious if this soapy water thing actually indeed makes a big difference, FYI i added the sealant after seating the bead.
3.One more complaint, I’m running enve 27mm tyre with the 3.4ses, and this combo is much harder than anything i have experienced, i have ran conti GP5000 TR on the previous gen enve, i have ran GP5000 STR as well, in terms of the difficulty of installing the tyre, enve tyre pairs with the new gen enve wheel is a nightmare, i don’t know how the enve support makes it look that easy on their video, i even need to use tyre lever to pull the first side of the bead into the rim, let alone the second side.
4.Oh one more super weird thing i have encounterd was sometimes the tyre holding the air just fine after the whole night, but once i take it outside for a ride, it suddenly started to lose air noticeably, and then i would use CO2 to pump it up then suddenly it seems like it’s holding the air for the rest of the ride, it seems like sometimes it leaks air sometimes it doesn’t, i am running tubeless on another two sets of wheels besides the new enve, haven’t encountered this problem at all.
FYI it has been 8 days now since i seating the bead and injecting the sealant, the sealant i use is Stan and 59ml for each tyre.
