Il set di ruote 303 S Tubeless Disc Brake di Zipp offre ai ciclisti di oggi la versatilità che richiedono con la velocità che bramano. Ampliando notevolmente la sua eredità di conquista delle classiche di primavera, questo set di ruote 303 mantiene la profondità del cerchio di 45 mm ideale per ogni terreno, ma aggiunge una larghezza interna significativamente più ampia per fornire maggiori prestazioni e qualità di guida in quasi tutti i modi misurabili. Le bici da strada sono più versatili che mai, indipendentemente dal fondo stradale, ma veloci come prima. La 303 S offre un profilo e un design del cerchio completamente nuovi per ottimizzare le prestazioni del ciclista su questa nuova razza di bici. Questo set di ruote è tubeless per bici con freno a disco, consentendo la possibilità di utilizzare pneumatici larghi a pressioni inferiori per una velocità pronta per la gara su o fuori dal marciapiede. La 303 S è tra le nostre ruote più leggere, ottimizzato per le massime prestazioni aerodinamiche con uno pneumatico da 28 mm ma in grado di gestire pneumatici gravel fino a 50 mm di larghezza. La 303 S prende in prestito concetti di design dal set di ruote per freni a disco tubeless 303 Firecrest di livello superiore per guadagnare velocità grazie a una maggiore efficienza. Ciò si ottiene creando una ruota con ridotta: resistenza al vento, resistenza al rotolamento, fatica del ciclista e peso. L'innovazione chiave è nel design del cerchio della serie 303 S. La sua profondità del cerchio di 45 mm è la stessa del suo predecessore, il freno a disco 302. Ma la sua larghezza del cerchio è più larga di 2 mm, a 27 mm, e il letto del pneumatico è più largo di 7 mm, a 23 mm. Quella piattaforma del cerchio è progettata per essere la più veloce con uno pneumatico da 28 mm. L'ampio cerchio ottimizza il profilo del pneumatico per consentire una minore pressione del pneumatico. Ciò aiuta a ridurre la resistenza al rotolamento e fornisce una guida più conforme. Il risultato di tutto ciò è un risparmio di watt del 10 percento rispetto a una ruota di pari livello in termini di potenza totale necessaria per percorrere 40 km/h su una strada piana e liscia con uno pneumatico da 28 mm, secondo i test interni di Zipp. Questo rivoluzionario set di ruote presenta anche cosmetici completamente nuovi, che distinguono il ciclista dal branco e ha un prezzo interessante.

CARATTERISTICHE

  • Grafica Zipp e identità cosmetica che gridano velocità
  • Il più veloce con 28 mm, si adatta anche a pneumatici gravel larghi
  • Hub 76/176 DB con interfaccia di bloccaggio centrale
  • Opzione corpo guida XDR
  • I cerchi larghi ottimizzano il profilo del pneumatico per consentire una minore pressione del pneumatico, soprattutto con tubeless. Il risultato è una zona di contatto più ampia per una maggiore aderenza per curve sicure, discese e manovrabilità in condizioni di bagnato.
  • Pressioni dei pneumatici inferiori e volume maggiore garantiscono una guida conforme con meno vibrazioni.
  • Notevole risparmio di watt quando si utilizzano pneumatici più grandi a una pressione inferiore.

Gli ampi cerchi hookless creano una transizione senza soluzione di continuità al pneumatico, riducendo la resistenza

Works fine overall, but... "you get what you pay for"
Size: Width 16.5", Fully Adjustable Desk Mount, Style: Single
Filed under: "you get what you pay for"? I like the price point and FOR THE MOST PART this arm is getting the job done in my home office space *but* a few points... (1) The little "claw" to hold the laptop in place has these little "locks" that are on the under side which... that's OK but they can be hard to see and it just seems like an extra part that can break -- vs. a ratcheting clamp. (2) The tension on every movable part was ALL out of whack when I first installed it. I set the laptop onto the cradle and it basically collapsed -- flipping down as far as it would go. I had to adjust the tension to be significantly higher in order to hold steady -- but NOW it's hard to "fine-tune" because the tension on that joint is so stiff. On the other hand, the main "elbow" joint is easy to adjust *and* holds steady all day, but within seconds of taking my laptop off of the arm, it springs up -- sometimes rather violently. (3) The overall build quality seems a little weak. The main screw to hold the laptop stand in place had a little cap to make it easier to twist it by hand -- but this snapped off during the initial installation. Not a deal-breaker because once it was in place, I didn't expect to move it again BUT it was still disappointing. (4) Not a deal-breaker for me BUT... there's practically no included cable management. Just... be aware of that. Otherwise... instructions were pretty clear vis-à-vis how to install and -- like I said -- it seems to be getting the job done w/r/t/ getting the laptop up off the desk and MOSTLY aligned with my other monitors.

Superb quality. Couldn't be happier.
Size: Width 14", Adjustable Desk Mount, Style: Dual
I have been looking for a separate monitor and laptop stand for a while now and recently came across this set up from WALI. For under $50, I was a little nervous about the quality before it arrived. I had no reason to be concerned. It is a SOLID set up. Everything is high-quality metal construction and secure when assembled. Set up took some doing but only because I am not the most, um, detailed direction follower...Make sure you tighten the tray and post screws TIGHTLY initially to prevent any kind of movement after you've assembled it (don't ask me how I know). I have a 15'' Asus laptop and the lip on the tray holds it fine as long as I don't tip it too far forward. But it's an unusually thick laptop body so I imagine most won't have an issue. Again, it's not a problem for me at all, just limits slightly the angle I can tilt the tray. If you are ok with the configuration shown in the primary product image (i.e., monitor above tray) then it will be no problem as is. My desk isn't that deep so I had wanted them to be side-by-side. I was able to set it up that way out of the box. But my monitor was just a hair too big and it cast a shadow on the laptop monitor in the side by side configuration. Support was kind enough to send me a second base post and screws so I could use the grommet and clamp bases at the same time (as is you can only use one or the other). This of course only works if you already have a hole in the desk (or are willing to put one in yourself). Many thanks to WALI's support crew for accommodating me. I use a standing desk. If movement while you type is something you're fussy about (I'm not) note there will be some shake, especially in the standing position. But for most, it should be absolutely no problem. Overall a fantastic deal. Highly recommend it!

A Powerhouse USB Hub That Handles Everything I Throw at It
Color: Gray
I’ve been using this 17‑Port 96W Powered USB 3.2 Hub for a few weeks now, and it has completely streamlined my workspace. With 10 USB‑A 3.2 ports, 2 USB‑C 3.2 ports, 3 QC 24W fast‑charging ports, and an SD/TF card reader, this hub truly replaces multiple adapters and dongles. The 10Gbps transfer speeds are legit — large files from my SSDs move quickly and consistently without random disconnects. The 96W power supply is a huge plus. Even with multiple external drives, peripherals, and a webcam connected, everything stays stable. No flickering, no dropouts, no “device not recognized” issues. The individual power switches are surprisingly useful too — I can turn off specific drives without unplugging anything. The build quality feels solid and premium. It doesn’t slide around, and it stays cool even under heavy load. The SD/TF card reader is fast and convenient for photo/video work. The QC fast‑charging ports are also great for topping up my phone or accessories, though they’re charging‑only (no data), which is clearly stated. If you’re someone who uses multiple devices — external HDDs, flash drives, cameras, microphones, card readers, etc. — this hub is a game changer. It’s perfect for PC setups, content creators, IT workstations, and anyone who needs serious connectivity. Overall, this is one of the most capable, stable, and well‑designed USB hubs I’ve used. Absolutely worth it.

Need lots of connectivity + charging. EXCELLENT.
Color: Gray
Problems with my original USB hub required something better. This unit has allowed me to connect all my peripherals to my laptop and I haven't had any problems with the USB port reliability I was dealing with. I'm using two hubs in series and now everything is working perfectly.

Yes, I wish I'd bought this on Black Friday, but still no regrets
Color: Gray
If you use a lot of add-ons like I do you won't regret buying this hub. The number of connection PLUS high power charging ports works for me. Printer, scanner, mouse dongle, phone, tablet, external drive, flash key all connect with zero problems to my Win 11 laptop. Saves my laptop ports from wear and provides a central location for charging my stuff. Solid metal construction, touch switches for each port, even slots forSDd and micro sd cards makes great design and features. Had a decent usb 3 hub but this one SO much better, good value
