Any multi tool that doesn't include a chain breaker is not worth having and this one doesn't. Although it does include three fairly superfluous sockets - for what purpose, I'm not sure.
A chain breaker will not only fix problems with the chain, but also allow you to bypass the front or rear mech in extreme situations. A chain breaker will get you home one way or another.
Also patches have moved on a bit now and there are some reliable self- adhesive products out there that don't need cement, which, incidentally, can eventually solidify if left for months without use.
All in all not a very good product even for a commuting bike, let alone a racing bike.
A bit more thought to practical considerations and real-life use could have made this better, as it is it looks like the kind of freebie you get when you subscribe to a new credit card in a shopping centre.
