    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.

    Okay tool

      I bent this tool on one of the first uses as well as snapped the 8mm hex cap on head. Yes it was taking off pedals at a trailhead but it honestly just wasn’t tough enough to handle things. Just spend 10-15 more dollars on multi tool and you will be happier.

      Minimal tool that has everything I need.

      • Familiarity: I've put it through the wringer

      I really enjoy this tool. I used to have 2 (one for my road bike and one for my mountain bike), but then I went on a trip and Ireland airport security confiscated it on the way back from a trip. Jerks. My only complaint is that the mounting slides/tabs to keep the tool all together on seem to break on the tire lever/chain breaker handle. Its not as big of a deal since I just leave it all in my saddle bag or my hydration bag. Overall I would recommend.


      • Familiarity: I've used it once or twice and have initial impressions

      QUALITY: haven't had to use it yet out in the wild, but tested it a bit and it loosed up nicely. Initially, a bit tight but no big deal.
      SIZE: compact and easily fits in this product EVOC SADDLE BAG TOUR
      WEIGHT: Feels a bit heavy, but I'm not hardcore so this doesn't bother me. I'm not an olympian.
      OVERALL: Solid purchase, happy with the initial quality & size

      Great Multi tool

      • Familiarity: I've used it several times

      Has all the right allen wrench sizes. Has a great chain tool design and great little tire iron to help with flats. If you are looking for a great tool that will fit in a little pocket this is it. Like other reviews have said it is a little sticky when you want to flip out a single tool, but it loosens up really quickly... so no problems there.

      Broke first try

        Good looking tool with lots of options. Manufactured very tight. When i opened it, they all came out together and when I was pushing a smaller allen key out of the way, it snapped off. WTF? I have always like Park tools for their quality but this not so much.

        Solid tool

        • Familiarity: I've used it several times

        Really well built and has everything. I haven't had it for long, so the tools are still a little sticky when I swing them out, but that could change with use

        Everything you need.

        • Familiarity: I've used it once or twice and have initial impressions

        Very solid tool, a bit on the heavy side but it is well built. Especially impressed that Park Tools managed to include a little tire lever into the unit. Havent had to use it yet but know it can handle most trail/road side fixes.

        Great Tool.

          I haven't had a chance to use it yet, but i guess that is a good thing as it means my bike hasn't broke. haha It has everything i could every need for a quick fix. Only issue is when you want to pull one tool out three others come with it as it was screwed together to tight. easy to fix by loosening it a little though.

          Always there when you need it

            I really dig my iBeam, it's the perfect size and light weight. Has just about every tool you might need trail side you get you back going again. The Chain breaker and spoke wrench are tools you don't thing you need, right up until they save your ride. Solid price of gear.

            Always there when you need it

            Clever Design

            • Familiarity: I've used it several times

            I've owned previous Park Tool multi-tools in the past, but was sold on this after using my Dad's when I broke my chain on an afternoon ride. I love that it includes a chain tool, along with nearly every other hex wrench I've needed - all while being as compact as my previous tool. Though, it seems like most of the hex wrenches could be longer than they currently are.

            It does the job

            • Familiarity: I've put it through the wringer

            Durable as expected with the hardened steel, but a little bit heavy. Does fit very nicely in the small backpack pockets. It did come super tight though and I had to loosen the hinges so I could actual get the tools to rotate out. That being said it does have everything you could need in a multi tool


            • Familiarity: I've used it once or twice and have initial impressions

            I bought this about a year ago, put it in my saddle bag and promptly forgot about it until yesterday when I needed it to fix a loose saddle. To my dismay, I discovered that it was thoroughly rusted and the hex wrench I needed - the 6 mm - was unavailable because the 8 mm cap had rusted onto it! What is the point of a BICYCLE multi-tool that can't tolerate the environment of a BICYCLE saddle bag???



            • 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.

            Great tool.

              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.)

              Follow up

                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.
