New Zipp 454 NSW vs Princeton Carbonworks Peak 4550

Hi All,

I am a bit unsure about these two wheelsets in subject (DISC bike dogma f12). Not sure which one to get, so looking for advice/feedback.

Type of riding: quite aggressive flat and laps (not racing). Average speed around 32-37kmh for 100km rides. I really like to climb as well, hilly routes and rolling roads. Not mountains frequently. Tend to climb between 25 and 30kmh but of course it all depends on the climbs. Body weight 85kg, ftp 340.

Peak 4550 tubeless disc brake clincher

Pros:

  • no need for rim tape
  • low weight at 1350g
  • nice aesthetics
  • all round rim depth at 45-50 undulating
  • seems like very good and stiff carbon
  • can choose freehub body (eg DT, Chris king, tune, white industries) and bearings (whether ceramic or steel).

Cons:

  • I don’t like the fact that the rim width is so small… 18.5mm internal and 26mm external. Even running just a 25c tubeless tire (eg. GP5000) would break the 105 rule as the inflated tire would be larger than 26mm (or just at 26mm).
  • the other Princeton version 4540 grit has much wider rim width (21mm int and 30mm ext) but it comes at a much larger weight for the set, so not too convinced.

Zipp 454 NSW

Pros:

  • low weight (1358g)
  • nice aesthetics
  • hookless allows lower tire pressure and more comfortable ride
  • wide rim width (23mm internal, not sure about the external can’t find the figure but it’ll probably be around 28mm)
  • allows for minimum 25mm tire which would probably be my choice of tire

Cons:

  • need for rim tape for tubeless setup (a bit of a hassle)
  • can’t choose hub so need to stick with their choice of bearings and body… might not be bad after all though.
  • I’ve heard Zipp wheels can give problems… not sure about this though
  • normally I’m not happy with the hookless compatible tires in the market. I currently have gp 5000 tubeless and really like it, but it doesn’t work for hookless rims. However, the new continental gp 5000 S TR tire is now hookless compatible - great news! That being said, unfortunately continental doesn’t seem to allow the combination of 23mm internal rim width with their 25mm tire. Zipp says it’s fine on their website, but continental has confirmed to me that it wouldn’t be an okay combination with their specific tire… but if I’d get a Pirelli or vittoria for instance, that would work… weird.

Other wheels I’ve considered are the Enve 3.4 SES disc or the AR version. Enve 4.5 SES or AR. And the Zipp 353 nsw but these have all different rim depths.

Do you have any advice? I don’t seem to find many reviews online for the Princeton 4550 peak and Zipp 454 nsw…

Thanks so much for your kind help!

IMO, the Princeton’s IW is a non starter. No way would I buy that narrow of a rim nowadays. Is there a reason you’re against running the 28mm tires? I have the 303 FC’s and absolutely love them.

I just love the feeling of 25mm tires (which, on wide rims, could have lower pressure and be even more comfortable). I did have 28mm and didn’t find them as good as 25mm, perhaps it’s just subjective feeing or the type of riding I do… perhaps would give it a try again on the Zipp…

If you like 25mm tires and higher psi, Princeton Peak would be better for you.

If you prefer 28mm tires and lower psi, 454 NSW would be better.

If value is a concern, enve ses 4.5 ar would be better than 454 nsw, although 200g heavier and 2mm wider internal rim. Also consider if you prefer the normal vs the wavy rim profile.

That said, I wonder when will enve introduce new generation of rims. Seems like the 4.5ar was launched 5 years ago.

A guy at weekly worlds has an f12 and Enve 5.6 disc, he loves them with 25c tires. I had those same wheels but sold them because I want to run 28-32c tires. Great wheels on flat and rolling terrain. I’ve used them in the mountains and they work well except in really heavy crosswinds descending above 35mph / 56kmh. The 5.6 are best in class in crosswinds, so any mid aero wheel would be too twitchy for me in those conditions at those speeds. Without strong wind I’ve easily descended at 50mph / 80kmh on steep downgrades. Great hooked tubeless wheels paired with 25c or 26c tires.

I’ve just bought the new Zipp 404s which have the same rim width and can tell you that your only option at 85kg (same as me) is to use the Schwalbe Pro One TLE tires with a 25mm on front and 28mm on rear as you will be up against the max PSI of 72.5. No other manufacturer (from what I can see so far) accepts running a 25mm tire on a 23mm hookless rim.

The 404s already have rim tape installed so would expect the 454s are the same and took me about 15 mins to get set up compared to about 3 hours with some Bontrager Aelous Elite wheels and the gp5000 TL 25mm tires.

I’m in a similar boat looking for proper road wheels - though weight is 68kg.

Currently in process of switching from rim to disc brake bike. Old rim brake bike is still my favourite and fastest (Pinarello F8 with Lightweight Obermeyer tubular wheels) but disc is the way of the future and am moving that way. Built up a 2019 Cervelo R5 Disc with with leftover parts from my gravel bike (clearance deal on the frame) when I upgraded the 3T Exploro to GRX (mix of Ultegra and Dura-Ace on the R5 - though using the ENVE 4.5AR wheels from the gravel bike on the R5). Actually really like the 4.5AR wheels on the R5 and at your size they are likely a good option if they would fit in the F12 - Pinarello can be tight with wheel/tire clearance.

I would not consider the Peak 4540s given your riding style, size and future direction of wheels. Great set of wheels for a 65kg kid in the mountains. You should consider reaching out to Princeton and asking about the Grit 4540s with the lighter weight hubs (DT 180s or their new Tactic hubs) - if they can get the Mach 7580 below 1500gm they should be able to do the same for the Grit 4540s. Big advantage of Princeton would be NO rim tape. Personally despise rim tape (can be a battle to get tight tires off hookless rims when flat - easy to disrupt rim tape and then really out of luck)

The ENVE 3.4 (non-AR) are a great option and a buddy of mine has them on his F10 with zero complaints. Given your riding style and size - consider the 5.6 Disc though they haven’t been updated in ages. Both are hooked rims which have their advantages - way easier to deal with flat tires (only time in my life needed to get picked up at side of the road was with my 4.5 ARs - getting a tight tire off a hookless rim can be a real treat… have learned many lessons since then but there is a learning curve to it).

Zipp 454 amazing choice as well - though stuck with Zipp hubs and rim tape.

Disappointed ENVE hasn’t updated their wheel lineup in ages. An updated 5.6 DISC is needed and would likely be exactly what your are looking for. Even the current 5.6 Disc with DT180 hubs would be light enough and very aero given the rims.

My dream wheel is something with ~55mm depth, ~1400gm weight, outstanding warranty, non-proprietary hubs, local maintenance (shipping the Obermeyers black to Germany for hub overhaul is no cheap/easy prospect), no tubeless tape, 23mm internal and 30mm external. Given all that - the 454s are probably the closest though the ENVE 5.6 DISCs (or 4.5ARs) could work very well for you as well.

Out of curiosity I reached out to Princeton and the Grit 4540 with their new tactic hubs apparently come in at 1306gm. No rim tape required and the security/simplicity of hooked rims.
