10 Times to Consider a Professional Bike Fit

It’s a trap we see countless cyclists falling into. They view a professional bike fit as a luxury – something they can do without and save the money for shiny new parts instead. In reality, your position on the bike is the foundation of your riding experience. Sure, some ceramic bearings or deep-section wheels might make you a tiny bit faster, but the biggest leaps in performance come from being on a bike you can ride comfortably and powerfully.

This is where an expert bike fitter, such as The Bike Tailor’s Stephen Roche, is worth his weight in gold. It’s their job to make you as efficient on the bike as possible by making millimetre-precise adjustments that can add watts and reduce strain. But how do you know when it’s time to enlist the help of a professional?

If any of the statements below apply to you, it might be time to think about seeing a fitter, and with The Bike Tailor’s professional bike fitting in London and Brighton, we can help.

THE BIKE TAILORS 10 CONCIDERATIONS FOR A
PROFESSIONAL BIKE FIT

Bought a new bike

In an ideal world, bespoke bike builds would be the norm, allowing for fully tailored geometry and a perfect fit every time. Unfortunately, this is expensive, so most people are forced to pick from a small selection of stock sizes that almost always need some adjustment to the bars, stem, saddle, cranks, pedals, or all of the above in order to get the fit right. A professional bike fit takes the guesswork out of the equation, ensuring you get the most out of your new machine.

Training for a big event

When volume increases, tolerance decreases. Niggles that were background noise at five hours a week can become ride-ending problems at ten or fifteen. An experienced fitter will look at load, intensity and position sustainability. Sometimes the answer is not more aggressive but more repeatable. A posture you can hold deep into the final hour.

Pedalstroke feels clunky

Riders describe this in different ways: dead spots, toe-down pedalling, rocking hips. Usually it stems from a relationship problem between saddle height, fore-aft position and cleat set-up. A trained fitter watches how force travels through the system and makes tweaks accordingly. Smoothness, in this case, often comes from millimetres, not miracles.

Recurring injuries

If you ride hard, you might experience the occasional niggle, or, heaven forbid, a crash. But when the injuries become a recurring theme with no obvious cause, that’s a big red flag for a poor fit. First stop, physio. Second stop, The Bike Tailor.

Dealing with an ongoing injury

Training doesn’t always have to stop just because you’re dealing with an injury. A professional bike fitter will be able to adapt your position on the bike to help you work through injuries wherever possible rather than ditching the bike altogether.

Online bike shopping

Buying blind can save you time and money… if you understand your numbers. If you don’t, it’s probably going to wind up being the opposite. A pre-purchase fit establishes your measurements and the ranges within which you can comfortably ride. Suddenly geometry charts become useful documents rather than abstract art, and you can leave the checkout process without a lingering sense of anxiety.

Discomfort

If you’re experiencing discomfort on the bike, that’s your body telling you that something isn’t right. The difficult part is determining what that something is. Trying to figure this out yourself can lead you on a wild goose chase, but an experienced bike fitter will be able to tell you exactly what element of your setup is responsible and advise you on the steps necessary to correct it.

New saddle, bar or shoes

Contact points play a huge role in the fit of your bike. Changing one can have a massive knock-on effect on position – even something as seemingly innocuous as swapping your saddle for one that’s a couple of millimetres wider can completely alter the way your body moves on the bike. A quick check-in after, or ideally, before making any such changes could save you from problems in the long run.

Guessing saddle height

Think you can just eyeball your saddle height and enjoy a perfect fit? Think again. Incorrect saddle height is one of the most common mistakes we see when it comes to fit. It’s also one of the easiest to fix, but only for someone who knows what they’re doing. If you’re blindly guessing your saddle height, chances are you’d benefit from a bike fit.

Saddle sores

Saddle sores are an unpleasant fact of life for anyone who puts a lot of miles in, but they should be relatively infrequent. If you’re getting them regularly, it’s a sure sign that there’s movement somewhere where there should be stability. Whether it’s friction caused by hips rocking due to a seatpost that’s positioned too low or the result of a saddle that’s too wide for the sit bones, a fitter will be able to tell and get you back on the bike, pain-free.

Why Bike Fitting Matters

A well-fitted bike isn’t just for WorldTour professionals. It’s for anyone who wants to ride longer, with less fatigue and fewer aches. The right position means better power transfer, improved aerodynamics, and real comfort in the saddle, without shifting, straining, or second-guessing your setup.

When you move efficiently, you recover faster too. It all comes back to the fit.
