Bike Fitting...

Bear with us a moment, the long novel below may seem a tad overkill, but trust us, bike fitting is not something you want to breeze through...

Often the difference between love and hate comes down to very small margins, and in the case of cycling it can be down to millimetres – if you get your bike wrong by just a few of these and in just a few short months the pain in your arse, your back, your knees, your legs and your wallet will see that shiny new purchase relegated to the garden shed along with the thighmaster 2000 and the rest of your good intentions, never to be seen again!

But get it right, and you’ll have discovered a sport that will benefit you for years and years. It sounds elementary, but a bike should assist you and complement your efforts, it shouldn’t slow you down, hurt you and waste your energy – this is what inevitably happens if a bike isn’t correctly fitted to suit a cyclist’s body geometry. The bike will slow you down, cause you unnecessary aches and pains and ultimately will leave you frustrated and cursing it to hell!

Now let’s be clear – there’s plenty of pain in cycling, but it should be healthy pain, so it’s the tell tale strain injuries that are unacceptable. Pain in your knees, lower back, and neck are symptomatic of an ill-fitting bike. The frame might even be correct, but then the saddle and handlebars may need to be dialled in to fit an individual’s geometry - it’s often a case of trial and error for many cyclists and as no two individuals are the same and for this reason there is no flawless measurement technique to suit everyone.

Irrespective of your bike's price or type we ensure all bikes bought from us are fitted correctly by going through a thorough in-store assessment of every individual's requirements - we back up these detailed visual and physical checks with plenty of test spins and also offer a borrowing facility so customers can try out different components such as stems, handlebars & saddles. Additionally, at the first free service, usually within 3 months, we address any niggles and make any adjustments that need to be made.

We work to suit individuals needs, for example if they are coming back from an injury, to ensure the bike is set up so that it will aid their recovery not hinder it.

Beyond that, we have implemented comprehensive in-store measurement systems from the industry’s leading specialists, bikefitting.com. These state-of-the-art systems will ensure a perfect fit for cyclists regardless of ability or budget. Due to the detailed and customising nature of these fittings we offer this service free on every bicycle over €2,000 to ensure all our customers have an enjoyable and long cycling career. 

On any bike below this rarified €2k mark, we are able to offer the same bike fitting for a heavily reduced fee of €50 (RRP€100+) due to the amount of time it takes but unless you have particular concerns or requirements we are confident our in-store assessments will have you fully covered.

For online sales we advise customers to follow the guidelines below but ask them to be mindful of any physical hindrances that may affect their positioning on a bike. Also, if you already have a bike that you are comfortable with that is the best way to make sure you get the size you want, so simply measure it along its key dimensions and match it with the size guides on the product pages. Bike geometries can vary wildly between the brands so please contact us if you need any help.

Step 1 

Measure your inside leg (in inches) to establish your stand over height – this is the clearance between the top tube of the bike (when standing just in front of the saddle) and your crotch. This needs to be 1-2” in order to safely dismount the bicycle if and when necessary.

Step 2

Measure your height in inches

Step 3

Now repeat step 1 and 2 two more times, and if possible get someone else to do it for you - maybe you’re not quite as tall as you’d like to think!

Step 4

One final measurement will help to ensure a better fit if you fall on two different sizes – it stands to reason that as the frame size increases so too does the distance from the saddle to the handlebars, this effects the reach and it is important to get it right to ensure you aren’t to stretched out or squashed in when on your bike.

To determine whether you have a long or a short reach you need to measure your Ape Index – this is your arm span from fingertip to fingertip minus your height. If you have a positive Ape Index you have a long reach so you should go for the larger sized frame, and if you have a negative Ape Index you have a short reach so should for the smaller of the two sizes.

Step 5

 Now that you have these three measurements you can determine your correct frame size. These generally come in 2cm increments for road bikes and 2” increments for mountain bikes – don’t ask us why!

Simply match your measurements against the Sizing Charts below and get ordering!

*Kids bikes are classified according to age rather than height. Although it may be tempting to order a bike size that they “will grow into” it’s very important for the child to be able to safely control the bike and learn the fundamental bike control skills that will last them a lifetime.
