Check out my freshest Primo Stevie cranks review!
There’s no faking toughness when it comes to BMX cranks – either they hold up, or they don’t.
The Stevie Churchill cranks are built with that exact mindset:
- no compromise,
- all power.
Inspired by one of the most savage riders in the game, these cranks aren’t just designed to look good – they’re engineered to take real-world beatings and come back for more.
From the heat-treated chromoly arms to the 24mm hollow spindle, everything about these screams overbuilt (in the best way).
If your riding involves stair sets, crank arm grinds, roof drops, or just going bigger than most – these are made with you in mind.
And it’s not just brute strength – Primo included the full bottom bracket kit with spacers, so you can upgrade your crankset right out of the box, without getting any additional parts.
Whether you’re piecing together a new build or replacing BMX cranks that couldn’t keep up, the Stevie cranks bring serious heat.
Let’s dive into why these are trusted by riders who push limits over and beyond every session.

3. How The Primo Stevie Cranks Ride
These cranks are made to go big.
Yes, truck driving El Torro BIG!
With the oversized 24mm spindle and wrap-welded pedal bosses, they feel extra stiff and precise when pedaling or stomping hard landings.
Whether you’re hitting rails or sending insane stair gaps, they give you the confidence to commit – and stay tight and quiet through it all.
One thing you don’t have to worry about AT ALL after installing the Stevie cranks is – well – your cranks.
Install it. Forget it. Send it.
Moreover, thanks to the included bottom bracket and spacers, installation and alignment are straightforward, and they’re built to handle anything the streets or parks throw at you.
I also really like the minimal branding on the Stevie cranks, which makes them look even better.
Clean and minimal-looking BMX parts are the best!
Last but not least, these cranks are pretty damn light for the insane strength they offer.

- “These things are tanks. Perfect for crank arm grinds, straight drops, 360s, etc., and they stay dialed.” – Marcus P.
- “Installed them once and haven’t touched them since. Clean and strong.” – Joey L.
- “I already send a bunch of 10+ stair sets and these didn’t flex a tiny bit. Love having 110% trustworthy parts on my bike.” – Tino G.
- “Glad they include the BB and all the spacers. Made setup super easy.” – Chris N.
5. Potential Cons Of The Stevie Cranks
- Only compatible with 24mm sprockets (15/16″) – luckily, most sprockets’ bore is 24mm, so you simply install it without any spacers.
- Higher price point ($200) – but justified for the performance + you also get the bottom bracket.
Conclusion: Should You Get The Primo Stevie Cranks?
If you’re serious about riding hard, sending it big, and putting your setup to the next-level test, the Primo Stevie cranks are an investment you won’t regret.
These cranks were built with street riders in mind – not just for flexing specs, but for real abuse, day after day.
The oversized 24mm hollow spindle adds stiffness without extra weight, and the wrap-welded pedal bosses mean you can throw crank arms on rails with full confidence.
But what really makes these worth it is how complete they are out of the box.
The included bottom bracket and spacers save time, money, and frustration.
Everything just fits – and it stays tight through your brutal shredding.
This is the kind of part you bolt on and forget because it just works.
No mid-session tightening, no flexy weirdness, no second-guessing.
Just raw performance that backs your riding, not holds it back.
If you want your cranks to match your level of commitment and help you progress, this is the upgrade to go for.
