ENVE Refresh?

[LedZeppelin007]

Yeah, 28s front and back here. The aero savings of a 25 should be pretty tiny.
For a hill climb I'd probably go 25 TT front and rear.

Thanks. I know the aero performance of the 2.3 is supposedly not great. How do you like them?

I’m very interested to see what Pogacar runs and when. Apparently he will mainly be running the 4.5 (according to Colnago) and their aero gains for the V4RS were based on the 4.5s versus “the wheel that Pogacar was generally running” (Bora WTO 45s?). Wondering if he goes 3.4 or 2.3 for the mountains in the Tour.

Really like the 2.3s for the mountains. Just rode them for 2 weeks in Tenerife. First trip to the high mountains after crashing in Granada, where I *f##k* up after I massive gust turned my handlebars on the descent.
This obviously hit my confidence pretty hard, and Tenerife being known for being windy af, I was a little nervous.
Saying "the 2.3s climb well" is a little pointless of a statement, imo. They are super mega light, and the modern internal width allows for wide tires to role quickly. Obviously they climb fairly well. However, most climbs in Tenerife are 5 to 6.5% average, where a more aero wheel, like the 3.4 for example, is probably faster.
The only bigger climb in Tenerife, that is so steep, that you'd only go light (Masca Climb, 10.9% for 4km), is probably the perfect playground for these. Not only is it f'in steep, it's also unsteady, so you accelerate and decelerate several times.
With that said,the climb came 90k deep into a 120k/3000m+ ride for me, so I can't really say I enjoyed it too much .

Edit: I kinda forget to get back to the point I was trying to make.
I really loved riding these wheels despite them not being the scientifically fastest on most of those climbs, for the stability, even in bad, gusty winds. They are mega light and super stable in the wind (which isn't super surprising for the low profile), and that's why I think they are amazing for riding in the mountains.

Thanks for the useful feedback. Sold the Mon Chasserals that came with my bike and was kind of regretting it. I really think the 4.5s are the ultimate wheel for me, despite me blowing one up (see above, Enve took care of me). I hate to sound like an industry shill, but I love hookless. Without it, I’d still be running 100 psi guaranteed. The 4.5s have shown me that the whole hookless system with huge tires can be really fast and comfortable. Compared with the 454s I had, the only thing the 454s had over the 4.5s was a slight benefit in stiffness and climbing. The 4.5s are more comfortable and noticeably faster on the flat, even with 29c Enve tires. I also thought that the 454s caught a little more cross wind (but were more predictable when they did, probably thanks to that sinusoidal whale thing).

Right now, I’m getting lighter and stronger which had peaked my interest in the 2.3s, so I impulsively picked some up when they were 20% off on a New Year sale. I’m looking forward to tackling a local 1 mile climb that averages 12.1%, but has extended sections of 20+%. Only climb that I do that have people passing me in cars and clapping for me, clearly thinking I’m insane. There was one point where I was doing 7kph doing 420 watts.

I'm running some 32c Vittoria Corsa Next on my 2.3's during the winter.

Has anyone laced up 2.3 with 180 hubs? Curious on the weight...

[FlatlandClimber]

You could just extrapolate it from the posted custom builds. Weight of 180s compared to Extralite is a known variable.

There are mulitple very steep climb on Tenerife where lighter > aero by a big margin. I will mention just a few major ones without going into side town roads which often go in to 25%-30% gradient territory:

1)Taganana beach climb: 5.52km, avg 9.5% (this one is comparable to Masca)
2)Afur climb: 6.7km, avg 8.5%
3)Villaflor - Teide climb (or more precisely from last cafe to the viewpoint): 9.44km, avg 6.8% but multiple sections close to 10% on the way.
4)El Fronton - Villaflor climb: no idea about the whole thing but last 4.16km has avg 8.6% gradient and the last 7.77km has 7.2% avg gradient
5)Climb to Teno Alto (from Palmar): 2.83km, avg 10% (good idea to do it as a warm-up before Masca )
6)TF 455 Climb (from Punta de Teno) - 0.93km, avg 12.3%

Needles to say there is big variation around average gradient on those roads so if it's 8.5% average there will be sections of 15%+.
I know it's not a thread about Tenerife but if you are there try those, they are all beatiful and worth it

True but was now article on bike rumours but honestly a weight different of say 200gr won't make a real difference.

But I'm really curious about the enve 4.5. Thinking about getting them and try tubeless for first time.
I'm riding some hooked rims 48/48mm height and got caught in Spain in a Marine hitting 18% hills and going down of course.
Honestly a lower wheel wouldn't have made a real difference as wind was blowing me all around
How are the 4.5 Enve rated ? Fit, finish ?

[FlatlandClimber]

I would like to run the 6.7 as a front wheel on my TT bike. Not super easy to find a fitting tire.
The GP5000TT are among the few super fast tires, that are HL compatible. I fitted the 25s and the 28s. The 28s are officially rated for a 23mm internal TSS wheel, but come out wide af (over 29mm). The 25s come out to just under 27mm, which is perfect in my mind.
Continental does not rate their 25s for anything wider than 21c. That's per ETRTO 2023.
ENVE however says 25s can be used on these wheels, and even up to 90PSI.
I know the safest route will be going 28s, but I'd like to hear your take here. The 25s are very likely fastest, and since this is for TTing, that'd be pretty high up my priority list.

[mrlobber]

You're an experienced and powerful rider, so it looks like you have already accepted the (small) risk of high-pressure hookless blowout. In that case, go for the 25s.

Personally, I wouldn't run anything wider than 25-26mm WAM hooked on the TT front wheel for the absolute majority of TT courses, and my choice of front wheel would be dictated by this (personal) requirement, not the other way around.

[FlatlandClimber]

You are right about the risk of blowout in general with Hookless. I don't do crazy stuff (sharp cornering at high speeds, cobbles etc.) with the bike, but obviously don't want to run an unreasonably high risk of hitting the deck.
I guess 25s on a 23mm internal should generally be fine (they were until a few months ago), but the discrepancy between what ENVE says, and what Conti says doesn't make things simpler to grasp.

try to find a 5.6 or 7.8 front to use.. not much different then new 6.7 in depth, but a small internal width.

Hard to say for sure, but it seems like my SES 5.6s with 25mm GP5K TT TdF tires catch more crosswind gusts than my Ascent Polaris 69s with 28mm GP5K S TR.
