Ruby, by CYBEX, is a new and innovative stroller, a superlightweight, weighing just under 12 lbs. It has a sleek frame, essentially the same frame as the high-end CYBEX Callisto, but without the bells and whistles in the seating, padding and recline. The Ruby"s straightforward fold is a 2 step mechanism operated by foot to collapse the stroller into a compact umbrella stroller. What makes it truly unique is that it can be used with a carseat (see list of compatible car seats below) thus bypassing the need for that a "Snap & Go" frame for the baby"s first 8 mo. It is an economical and smart stroller for parents in urban areas looking to save space and money on a travel system. The Super Canopy provides full coverage so that when it is unzipped and fully pulled down, hardly anything is left uncovered! We have not seen the like of this canopy on any umbrella stroller. The canopy also adjustsso that if a tall toddler sits in the stroller, the entire canopy can slide upwards to provide more head room. Comes in fun, daring colors to brighten up every excursion. FEATURES: Two position seat: upright and slight recline Rear-wheel suspension One touch, cable linked brakes Soft touch foam handles Shoulder carrying strap Ultra compact and extremely light Tall handles Stands up when folded Compact fold From 6 months up to 55 poundsCompatible with the following carseats to form a travel system with the infant carseat adapter, separate accessory.
