GCN Tech counts the hidden cost of a tiny sprocket
CeramicSpeed drivetrain tests underpin a gearing explainer, alongside championship bike weigh-ins and the continuing freehub-noise debate.
Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.
A 10T Sprocket Is Worse Than We Thought
A smaller sprocket can give you a bigger gear range, but GCN Tech's Sunday upload asks what that convenience costs at the pedals. "A 10T Sprocket Is Worse Than We Thought" has reached about 190,000 views and is the channel's busiest regular video by daily viewing.
Using drivetrain efficiency results from CeramicSpeed, the explainer examines the losses associated with bending a chain around a small cog, then adds chainline angle to the equation. Huge chainrings on professional bikes start to look less like showing off when the discussion turns to friction in time trials. A companion Short about ten-tooth sprockets is also drawing attention.
That gives the channel a fresh subject after its freehub-noise discussion, which remains the most-watched of the week's ten uploads. The show gets past the buzzing soundtrack to explain pawls, ratchets and silent alternatives. In the comments, riders discuss hearing their surroundings, keeping conversations going and childhood memories of cards between spokes.
Subscribers grew modestly, with another thousand joining over the week, although daily viewing is currently below its usual level. Across nearby sports channels, GCN Tech's weekly views were close to Lambros and Sky Sports Cricket.
Away from the drivetrain calculations, "We Weighed The Fastest Bikes At The Hill Climb Championships" supplied a wonderfully specific engineering contrast: drilled-out saddles and featherweight builds sharing the pits with aerodynamic setups and a custom trike. Ed Laverack's winning Scott Addict RC gets its inspection too, with strong headwinds making this more than a simple contest to remove grams.

I have ridden since the 90’s, and have never liked loud hubs. I like to hear what is around me.
@billysaurusbeanieSee it on YouTubeI personally think having a loud free hub is like having a card between the spokes, reminds me of when I was a kid 😂
