I just bought this; haven't needed to use it yet on the road/trail. First things first: as of April 2015 the This is a well made tool with elegant design. It's a bit on the heavy side to stick in a jersey pocket. I carry one in the luggage bag of my commuter bike and also in my Camelback on my mountain bike.The only reservation I have, and the reason I give 4 stars instead of 5, is that the small driver parts would be really easy to lose on the trail.I don't know whether the chain tool will work on an 11 speed chain. I'm told that they "probably" will and I don't like "probably" but I haven't found a good multi-tool that claims to have an 11 speed chain tool so I can't really complain much about this one.The title of this review pretty much covers it-this is a handy small tool, not much else to say about it.This is an interesting tool--one that's nicer to look at than it is to actually use. It's clearly meant to be portable, but it's awkwardly sized and takes up a lot of space for what it packs. Just look at the thing. Not an efficient use of space. Plus, when you pull out one of the triple tools in the middle, the other, which was magnetically attached, falls out, so one piece turns into three. Awkward. So how about in the shop? I'd still rather use larger hex keys with more comfortable handles. I burned a CO2 cartridge trialing the inflator. It works, but it's hard to modulate flow with. I've gone back to a smaller multi-tool and a Shiny Object inflator. That combo is lighter, takes up less space, and is easier to use.Everything you could ever want to do repairs on the trail to keep you going, set up in a handy, easy to use pack. The problem with most multi-tools is that they are so compact and small, when you do need to use them, they are nearly so impossible to use that unless you are miles from help it is almost more worth it to just call your wife and have her come pick you up.I always ride with my camelbak, and the Y tool fits easily in my pack. All I take is my Y tool, a spare tube, and a couple of C02 cartridges. I am good to go. No matter what.Crank Brothers has won a customer for life. This tool is not only super easy to use and small enough to carry around, but its so well made that i even use it for in home repairs. The tool has some weight to it which feels great to hold and has saved me several times from getting stranded. If you are looking for a tool to always carry with you or even just to have around the house, this is a very good choice.I can't believe the things I can do with this tool. It's great :)At the beginning I thought it was too big, but now I take it in the bag of the jersey and not even feel it is there. The accessory to attach the co2 container have never been used, but the rest of the tool is really helpful. In the reservoir for the small parts there's space for a small sand paper and few patches. So now I'm complete for a ride :)Perfect for what I wanted, mountain biking. It is a bit larger than i expected but it is light weight so even though it takes up a lot of space it's not heavy.This is a sturdy multi-tool and nicely designed. I find the tr-star design a useful one when bike fixing. I bought this to replace and Ice-Toolz one that cracked, and so fr this has been very useful and proves to be well madeEsta multi herramienta, trae lo necesario para que no te quedes en medio cerro, cuenta con llaves torx de diferentes medidas (las mas comunes), por ser de tipo estrella te permite tener un agarre firme y preciso, además de que cuenta con un valvula de inflado para cartuchos de CO2, troncha cadenas y varias puntas para usarla como desarmador, compacta y resistente, además de contar con un diseño vanguardista característico de CrankBrothers la recomiendo ampliamnente.Lo único que me gustaria que trajera son un juego de paletas para desmontar las llantas, ya que esas, las tienes que adquirir a parte.El material y acabados, son excelentes. Todo de metal.Por su diseño, entra en espacios reducidos en donde es difícil acceder a los tornillos para su ajuste. Creo que esta es su mayor ventaja.Otra gran ventaja, es que incluye el inflador para cartuchos de CO2.Las puntas incluídas, son las necesarias para ajustar cualquier componente en la bicicleta.Todas las partes de la herramienta, se integran y ajustan perfectamente de forma magnética, por lo que no se sueltan ni desprenden las pates.Por otro lado, le encuentro 2 desventajas: - Las diferentes puntas don piezas sueltas. Aunque traen su contenedor y este mantiene muy bien las puntas en su interior, no dejan de ser piezas sueltas, lo que facilita que se pierdan. - Su forma triangular, hace que sea un poco difícil su almacenamiento en algunas bolsas de sillín.En general, muy recomendable.Esteticamente molto bello, anche la qualità sembra buona come del resto tutti i prodotti C.b. .Le chiavi sono quasi la totalità di quelle che si trovano su una normale biicicletta.Da solo tre stelle perche pensavo fosse stato studiato per essere riposto nel borsello sotto sella di una mtb, invece è troppo largo, per cui un normale multi-attrezzi è migliore in fatto di ingombri.Anche la praticità non è un gran che.Punto a favore è la garanzia a vita sul prodotto ( o almeno così dicono!).Penso che in futuro ne prenderò un modello piu piccolo oppure il fratello maggiore di questo, che ha integrato lo smaglia catena e l adattatore per le bombolette di co2.Es una multiherramienta muy completa solo le falta allen de 8 mm, el adaptador de CO2 solo es parta válvula francesa (delgada) el único gran detalle que le encuentro es que la tienes que cargar en una cangurera o mochila forzosamente no trae adaptador para el cuadro ademas de que si improvisas traerla al cuadro lo mas probable es que se desarme.
