Il set di ruote per freni a disco Tubeless 303 Firecrest® di Zipp è progettato per il mondo reale... un mondo di condizioni imperfette, superfici stradali ed elementi in cui la linea di fondo è semplice. Efficienza = velocità. È più veloce, più leggero e più capace su vari terreni, indipendentemente dal fatto che la superficie sia pavimentazione in tutte le sue condizioni o nessuna pavimentazione. Profondamente radicata nella spinta di Zipp alla conquista delle Classiche di Primavera, la nuova 303 Firecrest è stata rifatta con un approccio mirato alle esigenze delle moderne bici da strada. Quando si tratta di andare veloci in bicicletta, efficienza significa riduzione: resistenza al vento, resistenza al rotolamento, affaticamento del ciclista, peso. Il freno a disco Tubeless 303 Firecrest è stato progettato utilizzando misurazioni dirette del mondo reale (rispetto principalmente alla galleria del vento o alla simulazione al computer). I risultati sono stati enormi. Il suo bordo ha un design leggermente più bulboso rispetto al suo predecessore, con una larghezza esterna di 30 mm, una larghezza interna di 25 mm e una profondità del cerchio di 40 mm. Il profilo offre una bassa resistenza aerodinamica e una migliore transizione tra cerchio e pneumatico, aumentando l'efficienza aerodinamica su strada. L'ampia posizione del cerchio presenta anche una minore deflessione del pneumatico per una ridotta resistenza al rotolamento. La combinazione dello pneumatico più largo, del volume maggiore e della pressione degli pneumatici più bassa aiuta a ridurre l'affaticamento del ciclista, rendendo più uniforme la corsa su pavimentazione imperfetta e condizioni stradali: il sistema di pneumatici e ruote assorbe lo scuotimento, non il ciclista. Al centro del freno a disco Tubeless 303 Firecrest c'è un nuovo mozzo versatile e durevole, lo ZR1 DB di ingegneria tedesca. Questo hubset presenta 66 punti di innesto per una risposta più rapida. Il set di ruote per freni a disco Tubeless 303 Firecrest è per ciclisti dedicati che aspirano alle ultime tecnologie. I suoi concorrenti... nelle gare, contro i coetanei, o semplicemente superando i propri limiti. Si tratta di diventare più veloci e di abbinare la tua motivazione alla tecnologia più avanzata.

Transformed my feet
Flavor Name: XL silicone socks 2 pairs
After trying several other brands that actually my size did not have the luxury feeling of these. T although x large they have the BEST feel and function. I put lotion on then slip them on and within a few minutes my dry cracked heals are soft. Really a nice product.

One of the best dog toys I’ve found
Color: Blue, Color: Blue
My Great Dane puppy- at 140lbs, loves this!! We had another one that was plastic and it worked ok but this is so much better! Interactive, soft to play with, battery last a long time & he does not get bored with it. Besides is plush lamb chops, best toy ever bought for him.

Keeps my wild child busy!
Color: Orange
*UPDATE 1/10/26* Does my pup love it? Yes. 5 stars for that. His big thing is just holding it in his mouth though, and laying down with it. Then he will put it down, and as soon as it rolls away he gets up and grabs it again. He definitely requires attention from his humans when it’s turned on…kind of defeats the purpose of why I bought it! He’s a needy boy, that’s for sure, so it’s not the toy’s fault. Two improvements I’d love to see though, are 1) the ability to turn off that yappy bark. I think my dog is more excited about it moving and not so much the yapping. Not that it’s bad, but my boy doesn’t bark much so I’m used to a quieter household. And 2) when removing the base for powering off, there should be a sensor so it doesn’t keep spinning in the socket, occasionally slipping out and hitting the floor. I worry about it breaking due to this. This thing arrived today and we couldn’t wait till Christmas to give it to our high play drive Australian Shepherd. It’s been barely above zero for weeks with no end in sight, and I have cold weather asthma so I really try to limit my exposure to the elements. Needless to say, my dog has been B O R E D. He truly craves interactive play with his humans, but last week I bought a cheap r/c cat toy that really caught his attention. So I splurged on this toy and so far, it’s AWESOME. He can’t control himself when the rope starts spinning. He pounces on it and it goes spinning off and around. He keeps picking it up thinking it’ll stop, but it keeps going. After 5 minutes of play he was acting completely gassed, but he just can’t resist it, as he put it down to get a drink of water and it started spinning again. Forget the water, I need that toy! As long as this thing can handle the teeth, slobber, dirt and grime, I’ll be a repeat customer!

My dog loves it...but needs charging four, five times a day. You really need 2 for full-time play
Color: Blue
My dog loves this toy. The first time she saw it and it started rolling, bounding, and waving the ropes around...she was barking at it, chasing it, grabbing it, jumping all over the place. There is no other toy she has that she will leave this for. And...that's part of the problem. I have to take this away from her three, four, five times a day to recharge it. The charge barely lasts an hour and the toy is dead. And it takes over an hour to charge it all the way up. Which means she plays with it less than it spends charging. That's not ideal. The product page and manual that comes with the toy says there is a 10-minute play period followed by a 30-minute interval to let the dog cool down...not get overly stimulated. I have never seen a cool-down period. I don't know if it's because the dog plays with it, shakes it around, tosses it and chases it, etc., etc., etc. constantly...but it just keep going until the battery is dead. I wish it did have a cool-down period. She likes playing with the ropes and rolling it around herself even after the battery dies, so if there was a cool-down, maybe it wouldn't need to be charged many times a day. Once it's charged and she sees me putting it back together, she gets very excited and starts jumping up and trying to grab it. Our corgi reduces most rope toys to threads in a day or less, and this one has held up surprisingly well against her super-chewing habits. The material the ball part is made of is very durable (we have a couple other toys with the same type of shell) and she's chewed on them all a lot without any damage. The toy keeps her entertained and happy...when it's not on the charger. I wish it was a good-enough value for the money to be able to justify buying two of them so I could have one charging while she was playing with the other. ================= I'm adding 1 star, because the company customer service is outstanding. They emailed me about my concerns vis-a-vis the short battery life, and it seemed that they really listened and cared about my input. I don't know what, if anything, can be done to extend the battery life given that it's spinning some substantial pieces of rope around, but I think they'll do as much as they can. In the meantime, my dog's love for this toy has not diminished in the least. She still gets very excited when she sees me starting to put it together after it's done charging, and she ignores everything else (sometimes even offers of treats) to play with it. I have a second one now, and I can almost keep them going full-time, but the few minutes every couple hours when both of them are on the charger is probably good for her anyway...she'd probably be over-stimulated if she had one of these to chase non-stop. Summary: Great toy, lots of fun, my dog loves it. However, you really need two the way things are right now unless you are okay with your dog being able to play less than half the time.
