HOW OFTEN SHOULD I UPDATE MY BIKE FIT?

By Anthony WalshRoadman CyclingUpdated 26 May 2026

ANSWER

Review your bike fit every 2–3 years as a baseline, and sooner whenever something meaningful changes: a flexibility shift, a significant weight change, advancing age, an injury or surgery, a new bike, or new components like a saddle, cranks or shoes. A fit is a snapshot of your body at one moment, not a lifetime setting. The body that was fitted three years ago has changed — and a position that was perfect then can quietly become the cause of new pain now.

KEY TAKEAWAYS

Every 2–3 years is a sensible baseline review even with no symptoms — the body changes slowly and silently.
Re-fit sooner after any trigger: flexibility change, weight change, age, injury, new bike or new components.
New pain on a position that used to feel fine is a signal that your body has moved on from the old fit.
Keep a written record of your fit numbers so you can transfer and compare your position over time.

WHO THIS IS FOR

IS THIS YOU?

The rider who had one fit years ago

You were fitted once, it felt great, and you've never revisited it — but new niggles are creeping in.

The masters rider whose flexibility is changing

You're getting older and noticing your old position feels more aggressive than it used to.

THE ROADMAN VIEW

A lot of riders treat a bike fit like a one-time purchase — pay your £200, get your numbers, done forever. Anthony's point, echoing what Phil Burt and Dr Andy Pruitt have said on the podcast, is that a fit is a snapshot of one body on one day. The body keeps changing. Your flexibility three years ago isn't your flexibility now, especially if you've stopped doing the mobility work, picked up an injury, or simply got older. The position doesn't drift, but you do — and eventually the gap between the two shows up as pain.

The triggers are the useful part to remember. A new bike obviously needs the fit transferred and checked. New components do too — a different saddle changes your contact height, new cranks change your leg extension, new shoes change your stack and cleat position. Then there are the body triggers: a meaningful weight change alters how you sit and where pressure lands, an injury or surgery changes your mechanics, and age steadily reduces hip and thoracic mobility. Any one of those is a reason to revisit the fit rather than soldier on with numbers set for a body you no longer have.

The Roadman habit here is simple and cheap: keep a record. Write down your saddle height, setback, stem length, bar drop and cleat position somewhere you won't lose them. That way you can transfer your position to a new bike without paying for a full fit, spot when something's been knocked out of place after a service, and have a baseline to compare against when you do go back for a review. New pain on a position that used to feel fine isn't a mystery — it's your body telling you the snapshot is out of date.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Dr Andy PruittPioneer of medical-based bike fitting; founder of the Boulder Center for Sports Medicine
A bike fit reflects the rider's body, flexibility and goals at the time it was done, and all of those change over time. Position should be reviewed periodically and whenever the rider's circumstances change — age, injury, weight, flexibility or equipment — because a position that suited the body years ago can become a source of new problems as the body changes.

Phil BurtFormer Team Sky and British Cycling physiotherapist and bike fitter
New pain on a position that previously felt comfortable is a clear signal that something has changed — usually the rider's flexibility or strength, sometimes equipment knocked out of place. Rather than pushing through it, treat it as a prompt to reassess the fit against the body's current state, not the state it was in at the last fitting.

PRACTICAL APPLICATION

DO THIS WEEK

Record your fit numbers and store them safely
Write down saddle height (bottom bracket to saddle top), saddle setback, saddle-to-bar drop, stem length and angle, and cleat fore-aft and rotation. Save it in a note on your phone and a backup somewhere else. This lets you transfer your position to a new bike, restore it after a service, and compare against future reviews.
Schedule a baseline review every 2–3 years
Even with no symptoms, book a fit review every two to three years. The body changes slowly enough that you won't notice the drift until pain appears — a periodic review catches the gap before it becomes a problem. Tie it to something memorable, like the start of a new season's build.
Re-check the fit after any trigger event
Treat these as automatic prompts to reassess: a new bike, a new saddle, cranks or shoes, a weight change of more than a few kilos, an injury or surgery, a long lay-off, or noticeably reduced flexibility. Don't wait for the next scheduled review — these changes alter the fit immediately.

FAQ

FREQUENTLY ASKED QUESTIONS

How often should I get a professional bike fit?

Every 2–3 years as a baseline, and sooner if anything significant changes — flexibility, weight, age, injury, a new bike or new components. Riders whose bodies are changing faster, such as masters cyclists losing mobility or anyone recovering from injury, benefit from more frequent reviews than that baseline.

Does my bike fit change as I get older?

Yes. Hip flexor and thoracic mobility both decline with age, which means a position that was sustainable in your thirties can feel too aggressive in your fifties. Many masters riders gradually raise their bars and shorten their reach to keep producing power comfortably. Revisiting the fit as you age keeps the position matched to your current mobility.

Do I need a new fit if I buy a new bike?

At minimum, transfer your recorded fit numbers to the new bike and then ride and reassess. Different frame geometry, a different saddle and different components can make the same numbers feel different. If the new bike is a meaningfully different type — say moving from a road to a gravel bike — a fresh fit review is worth it.

Will losing or gaining weight affect my bike fit?

A significant weight change can. It alters how you sit on the saddle, where pressure lands, and sometimes your flexibility and core support. A few kilos either way is rarely an issue, but a larger change is a reason to recheck saddle comfort and reach as part of a fit review.

Should I re-fit after an injury?

Yes. Injuries and surgery change your mechanics, flexibility and sometimes leg length or alignment. A position set before an injury may load the recovering area or compensate in ways that cause new problems. Reassess the fit once you're back riding, ideally with input from whoever managed your rehab.

How do I keep track of my fit between reviews?

Record your key numbers — saddle height, setback, bar drop, stem length and angle, cleat position — and store them on your phone and a backup. Check them periodically against the bike, especially after a service, so you can spot if anything has been knocked out of place and restore your position without paying for a full fit.
