What is OPTIS?
OPTIS (Odyssey Pneumatic Tire Insert System) is a lightweight, highly tunable, high-efficiency, tubeless tire insert. Tire assemblies are one of the most important performance factors for any bike. They provide all the grip to the ground, they serve as a critical first element of the bike’s suspension and they provide essential support to the cornering forces that the bike encounters. Pressure choice is always a compromise to balance these requirements.

Available in 27.5" or 29" sizes with a standard length OPTIS valve.

Why use OPTIS?
OPTIS prevents tire burping. By pressing the tire against the rim and preventing gaps from opening, burping becomes almost impossible.

OPTIS allows for lower tire pressures. The insert is inflated to a higher pressure than the tire, keeping the tire supported while allowing the main volume to be at a lower pressure that provides optimum grip.

OPTIS protects the rim and tire against impacts. The insert’s higher pressure provides protection against impacts, reducing the chances of tire pinching and rim damage.

OPTIS locks the tire bead and provides a temporary run-flat period if the tire is damaged. OPTIS will securely hold the tire to the rim for a short period of time if the tire is ever critically damaged and loses its air. This can allow for a brief run-flat period that gives the rider more control than they would otherwise have, providing the time needed to stop the bicycle.

OPTIS is lightweight. Wheel assemblies using OPTIS are significantly lighter than most of the alternative tubeless insert set-ups, while also providing greater protection. The OPTIS insert’s bead locking feature and tire support can also allow for lighter than typical tire and rim choices, resulting in overall weight savings.

OPTIS installation is easy and helps to seat tires. Unlike foam inserts, OPTIS installs as easily as a traditional inner tube, and inflation starts the process of pushing the tire beads outward to ease tire inflation.

OPTIS allows for low rolling resistance. By facilitating the use of lower pressures and lighter tires, rolling efficiency on rough surfaces is greatly improved.

WARNING: Like all pressurised tires, there is stored energy in an inflated OPTIS insert that is potentially dangerous. Do not inflate OPTIS inserts above 20 PSI except when mounted to a rim and inside a tire. Once fully assembled, do not inflate OPTIS above the maximum rating listed on the insert. Stop use of the bike immediately if the OPTIS insert is damaged. Adjust tire pressures as necessary to maintain safety.

Where it all starts
If you buy this you are about to start reading the greatest Batman run since... let's just say this is the greatest run on Batman. I may be over hyping this, the story arcs collected here are good on their own, but until you read the next volume and return to this one, your not getting the whole story. So it's hard to say how great this story is, and how great it gets. I would only get this if you plan on buying the other 7 Morriosn Batman books that follow this. Black Glove, RIP, Batman Reborn, Batman vs Robin, Time and the Batman, Return of Bruce Wayne, and Batman Must Die!. In that order. You'll have fun reading this run.

Visionary
If you're familiar with the work of Grant Morrison than you'll know this book was never intended to be read as a stand alone work. This is just the first few stories in a long run that culminate in Batman Inc. So, keep that in mind if you plan to jump on here. It's all or nothing. I'm always amazed with Morrison's ability to craft smart, universe encapsulating, severely polarizing stories in almost every one of his runs. His meticulous plotting, spot on characterization, and willingness to take chances are just three of the plethora of reasons to buy this book. If you like to be rewarded for paying attention and are looking for something more from your comics than "monster-of-the-week" this is for you.

I don't know, something's missing
I like the idea of Bruce Wayne being a dad - and with Ra's Al Ghul's daughter too. But is it just me or does it seem like there are gaps in the story; maybe there are other books in the story arc not in this graphic novel? When I got to the end of the book I was scratching my head saying "Is that it?" If you like Batman I suggest going to Forbidden Planet or your local comic shop and asking one of the people there to give you all the books around the arc so it makes sense.

A new Wayne
This book introduces Damian Wayne as the son of Bruce Wayne and Talia al Ghul. Bruce does not allow Damian to be Robin in this story as Tim Drake still is. Plus Bruce does not like Damian's attitude toward Alfred and Tim. This story does help to show just how talented (and violent) the future Robin is though.
