Park Tool I-Beam Mini w/ Chain Tool - IB-3 $0.00
One tool for all on-trail maintenance.
Whether you have to tune your derailleur, change a flat, or fix a chain, the Park Tool I-Beam Mini Fold-Up Tool includes what you need to get the job done right. A selection of hex wrenches, a T25 star drive, and a flathead screw driver helps you adjust, tighten, or loosen just about anything on your bike. Park Tool integrated a chain tool for those nasty on-trial chain breaks, and a tire-lever helps you get peel off the rubber to replace a flat. The I-Beam Mini Tool even includes two sizes of spoke wrenches to help you straighten a bent wheel.

- Familiarity: I've used it several times
Personally I generally prefer to carry more full sized tools with me since I have plenty of space in my pack. However, if you are looking for a super compact multi-tool that has everything you need out on the trail this is a great option. If you're hoping to keep your baggage light, you are in the right place. In my opinion you definitely sacrifice a lot of usability getting so many tools in such a small package... but the idea is that you will rarely use this and just keep it in your saddle bag, jersey, hat, shoe, etc. in case of emergency repairs so usability is not really a big issue. The price is surprisingly reasonable as well consider the Park Tool name, so I'm happy with my purchase overall. The tire lever is thin and not the most confidence inspiring so I personally carry another additional lever, but the incorporated spoke wrench is quite clever.

What chains sizes will it do?
Will it break my 7 sprocket 21 speed chain?
Thank you for your answers.
Yes the chain tool is for breaking the chain while replacing or just removing links.
It will break any standard mountain bike chain including your 21 speed.
I've carried this for a year in my jersey pocket on rides, and it's been great. I have not had to use the chain tool yet, but I've used several of the allen keys, and they've worked perfectly. Seems like high grade metal is used--I have not rounded off any of them. Not too flexy (I was worried about it being too flexy, since it only has one center support rail that ties the two ends together, but it's done just fine.) I've liked that it has a plastic tire lever that slides onto it on one side--the lever has been very useful to have a couple of times. I also wanted one that would work on a 10-speed chain (since some of my bikes has 10-speed chain and some are 9.)
So the integrated tire lever turns out to be a piece of junk. Used it for the second time just recently while home for the holidays and both ends snapped off while trying to mount a new tire. Expected much greater durability from a Park tool product.
Also, the plastic dovetail mount on the lever spreads a bit from use so it no longer stays put on the tool. This was the only thing keeping the loose bits from jabbing your hands during use.
Does the job
Pretty nice tool with most everything you could possibly need. The bits rotate a bit too freely and can move around in an annoying fashion since there are no side plates to keep your hands from bumping them while turning the tool.
I prefer the fit, finish and size of my Crank Brothers multi tool but appreciate the integrated tire level mounting on this one.
