Relentless Spur Shot V2: A $108 Slingshot With Bike Tools (Or Vice Versa)
The Relentless Spur Shot V2 is a CNC slingshot with bike tools. $108, 90g. Here's what actually matters and what doesn't add up.
The Relentless Spur Shot V2 is a slingshot that mounts to your fork or frame bottle bosses. It's also a disc rotor truing tool, tire lever, spoke wrench (3.23mm), Presta valve tool, 1/4" hex driver, and bottle opener. Fully CNC-machined from 6061-T6 aluminum now, versus the original's mixed construction. 90 grams. $108.
I haven't mounted one yet, but here's what matters: the spoke wrench is 3.23mm, which Relentless says is "most common on high-end bikes." That's true for a lot of newer road and gravel wheels, but if you're running older MTB wheels or budget builds, you might need 3.45mm or another size. Check your spokes before you buy a tool that only does one job adequately.


The pitch is that it gives you something to do on multi-day rides—shoot clay ammo at rest stops, true a rotor at camp. That's fine if you like carrying novelty, but the real question is whether you'd rather have 90 grams of this or 90 grams of something more single-purpose. A dedicated spoke wrench is lighter and fits more sizes. A real tire lever won't flex under load. The hex driver works, but you're already carrying a multi-tool.
Here's the catch: this is a $108 slingshot with some bike tools attached, or a $108 multi-tool with a slingshot attached, depending on how you justify it. If you're the kind of rider who packs a flask and likes messing around at camp, it might be worth the weight and cost. If you're optimizing every gram and dollar for function, it's not.
The CNC upgrade makes it tighter and probably more durable than the original, which is good if you're actually going to use the slingshot part. If you're not, you're paying for machining you don't need. It mounts cleanly to fork bosses, which is clever for visibility and access, but also means you're giving up a bottle cage mount or extra storage. That tradeoff depends entirely on how much water you carry and how long your rides are.
