New Shimano-Standard Cybrei Crank Increases Bearing Lifespan
Share
China Cycling just released a deep-dive on the new 24mm spindle version of the Cybrei carbon crankset, and it’s exactly the kind of evolution we like to see from serious Asian manufacturers. At Catalog Cycles, we’re constantly testing parts that promise real-world gains, and this one’s more than lived up to the hype.
If you’ve been following the space, you’ll know the original Dub-standard Cybrei crank has already earned serious street cred — from amateur race bikes to Tadej Pogačar’s time trial rig (in its SRM Origin form, no less). Now, with the release of the 24mm version, riders finally get a Shimano-compatible spindle with all the benefits of the original crank — and a few extras.
What’s New — and Why It Matters
The original Cybrei crank used a Dub-style 28.99mm aluminum spindle: big, stiff, and light. But in tighter bottom bracket shells — especially BB86 and BSA — the larger spindle size often leaves very little room for bearings. The result? Faster wear, more frequent replacements.
The new 24mm version solves that problem by using the Shimano-standard spindle size, giving you access to larger, more durable bearings. Combine that with Cybrei’s proven carbon arms and the same Cinch-style modular interface, and you’ve got a crankset that’s smoother, longer-lasting, and easier to maintain.
Key Tech Specs:
• Titanium 24mm spindle (Shimano standard)
• Larger bearing interface = improved bearing life
• 15g heavier than the Dub version
• $70 more, due to the titanium spindle
• Compatible with Shimano BSA, BB86, and other 24mm BBs
This also means riders can now swap cranks without needing to replace their bottom brackets — saving time, cost, and hassle.
Even Hambini — known for obsessing over bottom bracket tolerances — has been vocal about the downside of large spindles in small BB shells. This new version directly addresses those concerns.
Built for Compatibility
Cybrei’s 24mm version keeps the same Eastern Cinch interface as the Dub version, meaning it remains compatible with a wide range of spiders and power meters:
• Cybrei spiders
• XKD power meters (a fan favorite for value)
• Sigeyi, Magene, and Power2Max units
Whether you’re looking to run a standard spider or integrate a power meter, this ecosystem gives you plenty of room to grow — and most importantly, lets you choose your setup.
If you’re upgrading from a Shimano crank, this is a straight swap. No special bottom brackets. No spacing headaches. Just better performance.
Proven Where It Counts
This crank isn’t just theoretical — it’s already battle-tested. China Cycling’s race team runs it. GP Lama reviewed the XKD power meter setup and gave it a thumbs up. And perhaps most impressively, SRM now includes the Cybrei crank in their high-end Origin series.
That same SRM crank was spotted on Tadej Pogačar’s Tour de France time trial bike — which is about as solid a vote of confidence as you’ll ever see.
China Cycling reports hundreds of units sold, with zero carbon or spindle failures, and only a single bolt issue, quickly resolved. In the world of carbon cranks, that’s impressive.
Why We Chose It for Our High-End Builds
At Catalog Cycles, we’ve now standardized the 24mm Cybrei crankset on our high-end builds — and here’s why:
• It allows us to pair it with super-reliable Shimano bottom brackets — which we’ve found to be some of the longest-lasting, smoothest, and easiest to maintain BBs available.
• The titanium spindle brings excellent durability without sacrificing performance.
• The modular interface supports a wide range of power meter options, giving us flexibility depending on rider needs.
• It keeps weight competitive (only 15g more than the Dub version), while improving bearing lifespan in real-world conditions.
