Why Spoke Tension (and Balance) Matters More Than You Think

Most riders think a wheel is "true" if it spins without a wobble. That's only half the story - and it's the half that hides the real problem.

The Myth: Tight Spokes Break

Here's something that surprises almost everyone who brings a wheel into my Whitegate workshop: spokes rarely break from being too tight. They break from being too loose, or - more precisely - from sitting in a wheel where tension varies wildly from one spoke to the next.

A wheel can look perfectly straight and still be quietly failing underneath. Some spokes might be doing all the work while others are barely holding on. Every time that wheel rotates under load, the loose spokes flex more than they should - thousands of times per mile. That's metal fatigue in action, and it's exactly how spokes snap: usually with no warning, often at the worst possible moment.

And the maths on that failure is worse than you'd think. A single broken spoke on a Sunday ride costs you the ride and probably a taxi home. If it takes the rim or derailleur with it, a £2 spoke becomes a £100+ repair. A proper tension assessment costs a fraction of that - and catches the problem before it strands you.

Why Balance Matters As Much As Tension

A quick truing job can straighten a wheel visually without ever addressing tension balance. That's the difference between a wheel that "looks right" and one that's actually built right.

I recently assessed a pair of high-end carbon disc wheels, bought from a reputable high-end outlet. Both wheels were true and round. Both were also severely under-tensioned across the board. To the eye, and even on a truing stand, they looked fine. Under a rider putting power down, those spokes were flexing far more than they should on every revolution. That wheelset was heading for spoke failure - it just hadn't happened yet.

When I build or true a wheel, I use a precision tension meter to check every single spoke - not just eyeball it or go by feel. I'm looking for:

• Consistent tension across all spokes on each side - drive-side and non-drive-side tensions differ by design, but spokes within each group should sit within a tight, even range

• No dramatically loose or over-tight outliers - even one spoke sitting well below the rest is a weak point that will fail first

• Correct overall tension for the rim and spoke combination - too low and the wheel flexes, loosens, and loses trueness quickly; too high and you risk cracking the rim at the spoke holes

Checking and balancing tension across the whole wheel is something most workshops simply don't do. It takes longer than a quick true, but it's the difference between a wheel that keeps coming back and one you can forget about.

What This Actually Means for You

If your wheels are:

• Going out of true repeatedly, especially soon after being trued

• Making creaking or pinging noises under load

• Feeling vague or flexy when climbing or cornering hard

• More than a couple of years old and never had tensions checked

...it's worth having the spoke tension properly assessed, not just the trueness. Here's the cost logic: a tension check and rebalance is a modest workshop job. Repeated truing visits add up fast. And a wheel that fails completely means a rebuild or replacement - anywhere from £100 to several hundred pounds depending on the components. Do the maths.

Why I Build Wheels the Way I Do

Every wheel that leaves Leadout Cycles is built with quality components - Sapim spokes, DT Swiss rims, and Hope or DT Swiss hubs as my go-to combination - but components are only half the job. Build quality determines whether a wheel needs attention every few months or just quietly does its job for years.

Every spoke gets measured, every wheel gets balanced. It's the same standard I build race wheels to - including a set that carried a rider to a national road race championship win - because a wheel either holds its tension under load or it doesn't.
