If you’re considering upgrading your setup with a trustworthy part, don’t miss my extensive Eclat Spire cranks review.
These are FCKN epic!
High-end strength with clean, ankle-friendly design – that’s what’s up with Spires.
These cranks are made to ride hard and take punishment without feeling overbuilt or clunky.
The box-section arms and heat-treated 4130 chromoly tubing provide serious stiffness and dent resistance.
Moreover, the rounded spindle boss prevents your ankles from getting smoked when things get sketchy.
And whoever hit his ankle knows how painful it can be. (This is the only reason why I wear ankle guards.)
Bruno Hoffmann and the rest of the Eclat Pro team have tested the Spire cranks for over a year before the official launch. You know, just to make sure!
They are a refined 2.5 – piece setup with clean welds, smart geometry, and 0 fluff.
Let’s take a look at why they’ve become a favorite for both street and park shredders.
Eclat Spire Cranks Review
1. Key Features Of The Spire Cranks
Every inch of the Spire Cranks reflects Eclat’s design philosophy: clean, minimal, but absolutely ruthless when it comes to strength and reliability.
These features aren’t just impressive on paper.
They’re the reason Spires are trusted by one of the most progressive pro teams out there.
- Tubular heat-treated 4130 chromoly arms
- 22mm heat-treated hollow spindle
- 2.5-piece construction for solid strength and easy installation
- Box-section arm design for extra stiffness and dent resistance (also great for crank arm grinds)
- Smooth rounded spindle bosses to protect your ankles
- RHD/LHD compatible
- Available in 160mm, 170mm, and 175mm lengths
- Colors: Black, Satin Oilslick, Matte Raw
Fun fact: What’s the difference between a 2-piece and a 2.5-piece crank?
The former still comes apart, so you end up with two crank arms and the spindle.
With the 2.5-pc design, one crank arm is bolted to the spindle, so there are basically only two parts.

3. How The Spire Cranks Ride
The Spire cranks ride with a level of confidence that few others match.
They feel like they’re welded to your frame.
You don’t have to think about the BMX cranks after installing these.
Just full send – all the time!
Whether you’re stomping a harsh drop, cranking into a ledge, or blasting through a park line, the stiffness and control these arms deliver are unreal.
That oversized boxy shape gives more contact during crank arm slides, which translates to better balance under pressure.
The 22mm “ultra hollow” spindle keeps things responsive without weighing you down, and the rounded bosses are a true blessing for anyone who’s been wrecked by a sharp crank arm mid-line.
Or when catching a tailwhip.
It’s the kind of ride quality that you don’t notice because nothing goes wrong – they’re tight, clean, and completely out of the way, session after session.
Backed by a full year of testing from Bruno and the Eclat crew, the Spire cranks aren’t just ready – they’re already proven.
And with three available lengths, you can easily fine-tune your cranks according to your needs.
It just surprises me that Eclat also didn’t make these in 165mm.

5. Potential Cons Of The Spire Cranks
- No bottom bracket included
- Box-section arms are slightly bulkier than some riders prefer (but I love the look!)
- Raw and translucent finishes may show minor rust patches (normal, not a defect)
6. Who Eclat Spire Cranks Are Best For?
The Spire cranks were built with a clear rider in mind – someone who isn’t afraid to grind hard, go big, or drop even bigger.
If you want reliability (who desn’t?) baked into every pedal stroke, this is your crankset.
Best for:
- Street riders looking for stiff, grind-ready arms that hold up under abuse
- Park riders who want responsive cranks with a clean feel and minimal flex
- Riders who’ve dealt with ankle bites and want a smoother, rounder design
- Anyone on a short rear-end frame looking for 160mm crank options (check out my top benefits of shorter cranks)
Conclusion: Are The Eclat Spire Cranks Right For You?
Without a doubt.
Especially if you want a crankset that feels pro-level but still delivers day-in, day-out reliability.
The Eclat Spire cranks don’t just look good.
They’re the result of real testing, real engineering, and real-world feedback from riders who push their setups to the absolute limit.
The box-section design keeps everything feeling solid, especially on landings and grinds.
The smooth rounded bosses? You’ll thank them after your first near-miss with the crank arm.
What makes these cranks special is the balance.
They’re tuned for strength, ride feel, and long-term trust.
If you’ve ever had cranks creak, flex, or slip when things got heavy, you already know what it means to have gear that just works.
And the fact that Eclat offers these in a 160mm version is a huge bonus for riders on shorter chainstays or who prefer their feet closer together.
If you’re building a street or park setup and want a crankset that’s smooth, strong, and smartly built, this is the move.
Grab the Spires and ride with confidence. Every. Single. Session.
