Cybex Sirona Gi i-size

from 61cm-105cm/20kg

The latest car seat in our successful Sirona line is the most comfortable yet: the Sirona Gi i-Size. Extended rear-facing for safer travel up 20kg, this car seat also features integrated Linear Side-impact Protection for defense from all directions.

 

A range of innovative features also upgrade your child’s comfort, including 360° rotation in any recline position with the easy rotation handle, for smooth on and off boarding. Innovative all-round air ventilation means the ride stays cool, and you have the option of choosing mesh fabrics for maximum breathability with the Plus fabric version.

 

Five recline positions are available in either direction ‒ tailored comfort for your child, whether they’re a tiny newborn or a fully-grown four-year-old (newborn inlay accessory sold separately). 360° of comfort and safety for their first four years: the Sirona Gi i-Size.

UP TO 50% HIGHER SAFETY LEVELS*

Extended rear-facing – one of the safest ways to travel in a car seat. In the critical first moments of a frontal impact, the child’s body is pushed against the padded car seat shell. This keeps movement to a minimum and reduces force acting on the child’s neck. Mandatory up to 15 months (76 cm), we recommend keeping your child rear-facing for as long as possible. The Sirona Gi i-Size is designed for your child to sit comfortably rear-facing until they weigh 20 kg.

*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2022 ADAC frontal crash test criteria.

 

QUICK AND EASY ONBOARDING

A stress-free start to your journey. Just swivel the car seat using the easy rotation handle to face the car door and get your child onboard, in any recline position. You can avoid back strain, while your child stays comfortable in the recline position that fits them, whether they’re a newborn or a toddler. Switching from rear to forward-facing travel is just as easy.

 

OPTIMAL BREATHABILITY

The all-round air ventilation of Sirona Gi i-Size allows air to flow through ventilation channels within the car seat, carrying away heat and helping avoid a hot and sweaty ride for your little one. Choosing the mesh fabric available on the Plus version increases airflow even more – with up to 6 times more breathability than comparable car seat fabrics. The clear choice for comfort in any season.

 

EASY ONBOARDING

When you’re getting your child strapped into the car seat, you need all the help you can get. The Sirona Gi i-Size features ingenious loops designed to keep the harness out of the way as you get your child onboard.

 

GROWS WITH YOUR CHILD UP TO 4 YEARS OLD

As your baby grows, adjust the Sirona Gi i-Size headrest for a comfortable fit at every stage. 12 positions allow a tailored fit to your child, with the harness lengthening automatically with each adjustment. And it can be adjusted with one hand for extra ease of use.

 

SIDE-PROTECTION

The Linear Side-impact Protection defends your child against the force of a side impact. Working together with the energy-absorbing shell, the L.S.P. System significantly reduces the effect of impact force on the child.

 

ALWAYS IN A COMFORTABLE POSITION

For every moment, whether your little one is a newborn or a growing child, the ideal recline setting is available in both riding directions – and in the boarding position, too. And when your child falls asleep in the seat, you can recline it with one hand, letting them dream that little bit longer.

 

STRAIGHTFORWARD INSTALLATION

It only takes moments to set up your Sirona Gi i-Size. Use an ergonomic handle to click the ISOFIX into the vehicle seat and extend the load leg down to the car floor. Both provide stability and extra safety in the event of an accident. Visual indicators help you confirm the seat is ready to protect.

No more leaks!
Size: 8oz MTB Tire Sealant Kit
This product worked as it should and was easy to install. It connected to the presta stem with no issues. I have had issues with one tire constantly leaking at the bead and this finally sealed the tire.

Bought to hopefully seal bead leak
Size: 8oz MTB Tire Sealant Kit
I’ve been using Stan’s sealant on my tubeless tires for years! I have been having issues with a new tire for a while. It was like the bead wouldn’t seal on a specific spot and my tire was constantly leaking air. The local bike shop couldn’t fix it. I bought this product because it claimed to help seal bead leaks. So far so good! I really didn’t want all the doo-dads for the schrader valves. It took me a minute to figure out how to get the presta valve stem out but once I did- it was super easy to install the injector thing and add the sealant. After inflating my tires- I went for a 20 minute bike ride to get the sealant all around my tires. I’m going to take this bike out to pima-dynamite trailhead next weekend in Scottsdale AZ to see if the sealant holds up!!

Works like a charm!
Size: 8oz MTB Tire Sealant Kit
I’ve used TireJect before. I used it on my golf scooter to eliminate a slow leak. They only hold 14 psi, but over 4 weeks it was down to 10. The TireJect fixed that immediately. Very easy to use.

This stuff is amazing
Size: 8oz MTB Tire Sealant Kit
I have tried several tire sealants available for my tubeless mountain bike tires. TireJect far out performed all of them. The sealant is holding up well and definitely seals up punctures quicker. I've been stranded miles from the trailhead before and never again with TireJect. Carrying your bike back to the car is a walk of shame nobody wants face. I also liked the included injector better than the others I've had and like that's it's part of a complete kit.
