Lezyne SV 10 Multi Tool

Lezyne SV 10 Multi Tool

There are those items that, as a cyclist, aren’t really going to make your life better. They aren’t going to make you faster, won’t increase your enjoyment on the bike or help you lose weight. So caring about them suggests that maybe one has too much time on his hands.

Objective correlative: My mom used to get worked up about spatulas.

So, with that admission, I now submit my all-time favorite multi tool, the Lezyne SV 10. Is this the perfect multi tool for everyone? I doubt it, but it does have a few features that make it noteworthy. The reason it’s on my radar I’ve encountered a few stems and other components with Torx fittings recently and there are precious few multi tools that can handle this task. That alone makes this thing a win, but … you may not need those; before I go any further, let’s go through the compliment of tools this thing contains.

So this $45.99 little dooey has 2, 3, 4, 5, 6 and 8mm Allen keys; the 2 is L-shaped. There’s a Philips-head screwdriver and T25 and T30 Torx bits, plus a chain breaker than can handle 9-, 10- or 11-speed chains. It’s virtually every tool I’ve ever needed on the road.

Notice how this thing is bright and shiny, like it was made by a jeweler and it’s simply waiting to have a bunch of rhinestones encrusted upon it so it can be sold to the world’s only paprazzi-evading cyclist? Well I didn’t take that shot when the thing was new, out of the box. I shot it this morning, following months in either a saddle bag or my jersey pocket. No amount of sweat or road spray has caused the least bit of corrosion on those stainless steel bits. The issue here isn’t that I’m some effete, fair-weather rider who can’t deal with some rust. It’s that I’ve encountered tools that were so impossibly neglected that they had rusted to the point that I once found myself trying to grind rust off a 4mm Allen key on the sidewalk because I couldn’t fit the damn thing in a seat binder.

We can all agree there are better ways to spend your time, can’t we?

With a weight of only 100 grams (exactly—I swear—thanks, in part, to CNC-manchined aluminum for everything that isn’t a tool) and a construction so slim that it didn’t really affect pocket capacity, the SV 10 has become a regular part of my riding. And because I’m in the process of reviewing a number of bikes, I’ve had a more than typical need for a multi tool. Multi tools ought to be like insurance, there only in case you absolutely need them, but if you do, they need to do the job right, and right away. Lezyne makes a few other versions of this tool, with either more or fewer bits, but more and more components are coming with Torx fittings, so these tools, I expect, will become more and more necessary.

Being prepared is a kind  of win. Just ask the Boy Scouts.

    Why the Torx fittings? I understand that Phillips improved upon slotted because you were less likely to slip. I’ve seen square-headed tips on some of the screws I drilled into my kids wooden swingset/nightmare project. While I hate it when Phillips screw-heads strip out. Does Torx really offer a better survival rate for the torque you typically put on a bike part?

    I think there’s someone in the tool industry trying to come up with a new fastener head so he can sell 8 new screwdrivers to every ‘Tim the tool guy’ out there.

    That moaning done, thanks for the review. I bet I have 4 multi-tools. None have the Torx head. Thankfully, my bikes don’t require them – YET.

    I own this tool (or something with a couple more sizes, but the SV version). It has survived well in the salty winters here.

    @Tom – Torx will probably be more useful to riders that are not exclusively roadies. In my case, they are used in my MTB brakes (inexpensive mechanical Avids on a snow bike). They have been handy to loan a couple of times. I think they are used in some stems, too (ARX Pro from 3T?).

    I read somewhere that they resist slippage better than hexagonal wrenches since the torque is applied more perpendicular to the slot (the point of the star), and that this allows to use smaller heads for similar applications. Whether this is good when you don’t really want to overtorque a carbon stem or a binder, I don’t know.

    And I will ad – the chain tool actually worked when I snapped a link on a muddy ride last year. It was on a 10 spd. CX bike, so no idea if it is good on 11 cog systems.

    Torx is standard for all new Campag, 3t and others. I’ve actually had trouble finding multi tools with enough coverage of the standard.

    I’ve been using this tool for a few years and think it’s the best one on the market. Admittedly, I shopped all of the alternatives before purchasing it. Yet, it has exceeded my expectations, the best of which is that it is rust free. All other multi-tools I’ve used have rusted in less than six months.

    However, for the first time, it let me down yesterday. My bottle cage loosened mid-ride and it was too wide to turn within the tight confines. Nonetheless, I remain a huge fan of this tool and highly recommend it.

    @Pat O, I always carry a tool that has a chain tool built into it. But, I’ve only used that feature 3 times that I can recall in the last 7 years. It’s not a must have and maybe I shouldn’t bother, but I do.
    I sometimes go to my carry tool for breaking the chain at home, as well. That’s where I use it most.
    You might have a point about not needing to have this feature on a carry tool. I guess it comes down to how patient / forgiving one might be if they find themselves needing one an hour or two from the truck / home.

    I have a diff version of this tool (what sold me was that it had a spoke tool for Mavic Ksyrium nipples built into the chain breaker). I’ve used the chain tool once (so far)…my wipperman removable link suddenly parted (no idea how) and one side was flung into the void, never to be seen again. Was able to carefully break a link and re-push the pin, thus connecting my chain (albiet 2 links shorter..I now carry a spare replaceable link…lesson learned). Got me home tho. I’ve used my Crank Bro’s multi-tool chain breaker on my MTB more than a few times…it’s MUCH more critical to have one when you could be HOURS from help). Nice review tho…if I ever get rid of my Mavic wheels I’ll consider this one.

    Chain breakers, spoke wrenches and a valve core wrench built in to your multi-tool are seldom used but essential when you’re hours from anywhere. All too frequently I have been the one rider in a large to huge group who had either on with me when another rider needed one. The other thing that amazes me is how few riders know the basics of using a chain breaker or spoke wrench. I’m not pro mechanic level with either but I can get a wheel to stop hitting a frame and a chain back together and/or loosen a stiff link and that’s what matters when you’re in the middle of nowhere and something unusual fails on your bike. Now I’ve gotta go touch wood.

    Torx needed for mtb disk rotors. I admittedly have a smaller and lighter multi tool for the road bike. But for NUE distance mtb races, this is the only tool in the bag…

    Thanks for the review and helpful follow up comments. I’ve been mostly lucky carrying the most minimal tools but it’s time to get some insurance and mechanical know how and this looks like a really good tool to have. Especially since I have 3T parts and Kysirium wheels.
