CECO-USA 17 Function Bike Tool with Chain Breaker – Bicycle Multi Tool – Ultra Slim, Compact Pocket Sized, Lightweight – High Strength CR-V 6150 Tool Steel – Easy To Carry

The Ceco 17 is a good compromise in the number of tools vs. the size and weight. It’s also flat and doesn’t have pointy edges – useful if you keep a spare tube nearby.

For comparison, the very well made Crank Brothers M17 has better access to each tool, but is both heavier and more bulky. That said, the Ceco is still noticeably heavier than the Topeak Mini-6 that I carried before.

The Ceco comes with a woven pouch, into which I was also able to stuff two of Shimano’s ultralight spoke wrenches, some zip ties, and a couple of card-type tire patches.

I recommend carrying one miniature, flat-bladed screwdriver in your kit. The screwdrivers on these multi-tools often aren’t able to reach the low and high limit screws on the front derailleur.

Overall: This seems like the perfect balance of size, weight, and functionality for my bike rides. 114g, super tiny, and does everything I would need with no extra tools that I wouldn’t want to carry. More details and potential downsides are below.

Originally, I was trying to purchase the Pro Bike Tool 17-in-1 multitool, which was lightweight and well-reviewed by Outdoor Gear Lab. It was not available to ship to the United States (despite appearing to be available on their website). This, and other tools on Amazon, appear to be the exact same design – if not the exact same tool. It seems very solid and at least this is a US-based seller of the tool (they are in California). Like all tools of this design (small and wide-bodied) there might be places on the bike that are awkward to access. So, you may not be able to fully rotate the tool – you might have to do many half-rotations – but that is the price you pay for having something so compact with so many functions.

Other info:
– CECO is apparently “California Equipment Company”. They appear to be a USA owned company. I’m sure they source their tools from the same overseas places as other Amazon sellers (and likely Pro Bike Tool, too).
– Weight was surprisingly accurate at 113 or 114g (my scale bounced back-and-forth between the two before settling on 113g).
– The optional padded case is 13g more. There’s room to stuff some very thin/tiny items in the case, but not much.
– If you want to tighten the bits (so they rotate more or less easily), this is down with a simple hex key (allen wrench), so that is easy to tweak.
– Everything closes fairly flat, so it’s a very compact item.

UPDATE: Functionality is very good and it seems quite sturdy, but be mindful of limited leverage for some tools. Examples:
– The 6mm hex was plenty strong for removing thru axles. It never felt like I was straining the tool. That’s great, just realize you’ll have limited leverage given the size of the tool.
– I tested the chain breaker on an 11-speed chain. It definitely works and seems solid for emergency use. HOWEVER, it is difficult to get enough leverage. The main problem is there is very little to hold onto when breaking the chain (see photos for what I mean). As a fit and fairly strong male, I could break a chain with some effort. I’m not 100% sure my wife would be able to do the same. It would probably be a struggle for her.
– All of the allen / hex keys and other bits seem appropriately sized (not a super tight fit, but no looser in bolts than my other multitools from name brands.

About that 8mm “socket” that fits over the 5mm:
– The socket sticks up slightly from the tool. Not a huge deal, but it keeps it from folding completely flat.
– The 8mm socket is a clever way to get this size hex without making a super-heavy tool, but it is removable and could be easily lost on the road or trail.
– That said… Is it worthwhile to have an 8mm hex on a tool this small? You certainly aren’t going to get enough leverage to remove a pedal with a 2.8-inch multitool. And pedals are self tightening, so they don’t come loose on the trail. My cranksets use 10mm hex (or require specialized tools) for tightening, so not useful there, either. I guess there are some cranksets that take 8mm. So maybe for tightening a loose crankarm, *if* your cranks takes 8mm hex?
– I leave the socket it at home, so I have more room to pack stuff around the tool within its little case.

My repair kit is below. You can stuff a few *very tiny items* into the case (just barely). I have included:
– Park Tools tire boot (size of a business card)
– Park GP-2 glueless tube patch kit (about the size of coin)
– Two 11-speed quick links connected with a twist tie (i.e. for reconnecting a chain)
– The tiniest tubeless plug kit around (Genuine Innovations tubeless fork + a few bacon strips)
– Thin tire lever, which I cut in half. A typical, thicker tire lever certainly wouldn’t fit.
That makes for a fairly complete repair kit in a tiny package.

This tool set folds down very small and was very easy for me to just throw into my top tube bag and forget about. All the bits seem well built and functional. I was worried about the reach of the bits at first because some screws in my bike derailleurs are inset but the tool’s smaller bits for those adjustments are actually longer so it does still reach. My only complaint is that the bag it comes with is a bit too large for it. Also, a minor nitpick, one of the bits could be twisted a bit so the chain tool can fold more flat against the tool.

This is an excellent value, well made tool that feels great in hand and just works right.
The bits are fixed at just the right tension to be easy to fold out without any slop, are precision fit for their sizes and have shown no signs of rounding off.
The chain breaker works better than the standalone tool I had for years before buying this.
The protective pouch is a nice added touch, but everything folds to such a slim snug package without any sharp edges that I often just carry it loose in my back pocket. I like this tool well enough that I keep it in mind as a gift for my cycling friends.
