BlackburnBig Switch Multi-Tool(Return to Product Page)

Affordable and easy to use, but a couple of strange design choices that have lead me to go back to my 15 year old rusty Topeak multi. First, the case is strange and doesn't quite close as well as it could. Second, there is no included phillips bit. Thirdly, and the biggest offense for me, is the decision to make the 3mm and smaller hex keys ball-end. When I'm on the side of the road making an adjustment, I don't need to be worrying whether or not I'm about to round out the 3mm bolts on my Thomson stem. It's a bizarre design choice and I can't think of any situation where I'd prefer ball-end over straight hex, especially in roadside/emergency situations.

This is a convenient, compact way to carry the tools needed to tighten most of the fittings on a bike. It is sturdy and also has a spoke wrench and chain break tool. Not quite as important now with missing link connect chains, but if you were to ever break a chain you would be able to remove a link and fix it. A friend had this happen when apparently a small rock got lodged in his chain and separated a link from the pin. Unfortunately he didn't have a chain tool, so he tried press the link back in the pin using rocks. This worked but he could not put much pressure on the pedals w/o the chain coming apart again. I would not go on a weekend gravel ride or extended bike tour without this tool. It and a Leatherman Squirt (good pliers) should get you through most any emergency.

This replaced a loose asortment of hex wrenches in my seat bag. I have used the wrenches to try them out in the parking lot but not on the roadside yet. Tire levers fit nicely under the strap. I have added a couple of phillips screwdriver bits which fit into the hollow of the handle.

This seems like a well-made tool at a good price. My only complaint would be the carrying case, which doesn't fasten close, but is held close with a wide rubber band. Seems like there are much better options. Otherwise, I like this.

Seems like a decent little tool set. However, like an earlier reviewer, I struggled with/disliked the rubber band closure. So, I replaced it with a Velcro cable wrap. Done.

I like the way this tool packs. Very easy to carry in a jersey pocket or saddlebag. It has a good variety of tools and you can actually generate some leverage with it. I have used it some around the bike shop to familiarize myself with it but not in an emergency repair yet. It appears to be well built and nicely engineered.

I threw this in my bike bag and forgot about it until I had a chain link come loose 10 miles from home. I dug out the tool kit and was very relieved to see it included a chain tool. The ride was saved. Now any time a saddle needs adjusting I do not hesitate to stop mid-ride, pull out the tool kit and make micro-adjustments.

I like this tool a a lot. Being able to use it as a T handle or straight driver is good. Seems well made but the case could be better designed - does not fit snugly enough. Good selection of drivers. I haven't used it in battle yet so will see how it goes.

Haven't really had to use it yet so .. but seems well made and I can carry just the bits I want. Fair price.

Simple tool and fits better in my pack than a multi-tool which is normally jammed into my back.

This is a nifty tool. You can reconfigure it in different ways depending on the scenario. For example, if you need more torque, insert one of the bits you aren't using into the end of the handle.

The only thing I don't like about it is that whenever I use it to adjust my bars or my seat, I get at least 5 riders passing by who ask if I'm OK.
