- Find a bike. your size. your shape
WHAT IS A GEOMETRY SEARCH?
The geometry search tool uses standard bike frame geometry which can be found on bike manufacturer websites. If you know which bike is a comfortable fit you can take these measurements and search for other bikes that are have the same geometry. Alternately you can measure your own bike (assuming it's the correct size and shape) and search using those measurements.
Due to the wide range of variables in bike geometry and the associated components our search tool has been designed to use only key dimensions and angles necessary for sizing.
A good knowledge of the interrelationship between geometric dimensions and angles is recommended but not required when using this search tool.
Our Geometric Definitions section provides a more thorough and detailed understanding of bike frame geometry. The Pointers & Tips tab also provides further information and useful tips.
HOW TO MEASURE YOUR BIKE'S GEOMETRY
Measurements:
(A) Top Tube (centre of head tube/top tube to seat post centre) (B) Head Tube (fork/frame juncture to headset cap) (C) Seat Tube Angle (use an angle finder)
The seat tube angle is optional as it may restrict your results significantly. Unless you’re 100% sure about the accuracy of this measurement we recommend you leave it out.
Please note: All measurements must be accurate to the millimetre. We highly recommend using measurements from a manufacturer’s geometry table or enlisting the help of a bike fitting professional.
POINTERS AND TIPS FOR USING THE GEOMETRY TOOL
-
A) TOP TUBE
Top tubes (A, B) can be measured as either actual (sloping) or theoretical (horizontal). The most relevent measurenet is always the theoretical horizontal, otherwise known as "effective". 99% of manufacturers use this measurememt and will have that number listed on their geometry charts. This is the measurement we use. -
B) SEAT TUBE
Seat tube lengths can be measured in number of different ways (C, D, E).
Each bike manufacturer uses their preferred version but for the purposes of this site we will always use the centre-to-top measurement. On modern bikes seat tube length is really only important to establish whether there is too little or too much seat post extending from the frame, often a largely aesthetic exercise. -
C) SEAT TUBE ANGLE
Seat tube angle (F) plays a big part in correct placement of the saddle.
Thus if the seat tube angle is too far out of range you won't be able to achieve correct saddle placement despite the adjustment available on your seat pillar. Finding out what seat tube angle best suits you is a difficult task, so that field is best left blank if unknown. However, when searching for Tri or TT bikes it's always best to fill that field in. -
D) HEAD TUBE
Most head tube measurements (G) are based on a modern integrated headset design. The exceptions to this are bikes which use an external headset (usually old or handmade bikes) in which case the overall head tube length includes the added height of that external headset. If you have a bike with an external headset (see pic) always measure the head tube including the lower and upper portions of the headset. If you need help just let us know. -
E) HEAD TUBE ANGLE
Head tube angle (H) plays a small part in the overall geometry, and it is too difficult a measurement to include in the search fields Additionally this angle is intricately linked with handling so would serve no purpose being included in our search system. Please be aware that a slacker head tube angle (70-72 degrees) brings the bars closer to you whilst a steeper head angle ( 73-74 degrees) takes the bars away from you.

Resuts include all bikes within the parameters you have set and include the year model due to the fact that geometries sometimes change. In the event of limited or no results use the message box on this page and we will get back to you within 24 hours to resolve the problem.
