Bike Frame Size Guide

Once you have funded the resources for buying your desired cycle, you move towards more intricate decisions. One such decision is to face the turmoil regarding choosing the right cycle frame for yourself. The act of choosing the appropriate cycle frame appears puzzling due to the contemplation of so many factors beforehand.

Selecting the material of the cycle frame to pinpointing the appropriate size as per your physical traits is confusing at times. In order to relieve you from the dilemma prior to the purchasing of cycle frames, we have devised a 5-stepped guide. It will instruct you upon the consideration of cycle frame material, measurement of tubes, length to height proportions of your frame and other practical issues.

We understand how choosing the unfit frame can ruin your investment as well as deprive you of comfortable rides. Thus, we urge you to consider the following details before purchasing your cycle frame.

Purchasing a bike is a simple process until you learn about the multiple material options for the frame. It can get quite confusing as to which bike frame material you should go for.

Bike Frame Geometry

You cannot succeed at choosing a perfect frame for your cycle if you don’t pay attention to the geometric angles. The Geometry of the cycle frame portrays the angles at which the different tubes are arranged and how they slope towards each other. Currently, cycle frames are structured by two types of geometry; named, Compact & Traditional.

Compact Geometry

The Compact geometry frame comprises of revolutionary features much different than the contemporary top-tube frames. Therefore you’d notice 2-3 inches visible amount of seat-post contrary to the baseline upper tube cycles. However, the contact points are so alike that you would feel the same sensation as your preferred cycle while mounted on top of such framed cycles.

If you are muddling over how to identify the compact geometry frames just look out for the top tube, wheel-base & real triangle. Because compact geometry frames consist of the small rear triangle, short wheel-base, and a sloping top tube. The resultant frame provides for firm yet responsive rides while also bearing minimum center of gravity properties.

Traditional Geometry

The traditional geometry frames are featured by top tubes oriented analogous to the ground. Such geometry bears smaller frames followed by limited space while being mounted over the cycle. If you would like to compare a traditional geometry frame with a compact geometry frame we can exemplify that, a 64-cm traditional frame cycle would be equivalent to a 60-cm compact framed cycle.

Don’t Falter with Length!

The length & size of your cycle is the decisive factors behind your comfort while riding the cycles. However, the top tube length demands most of your attention. This length is firstly considerable by the distance between the seat-post and the head tube.

If you purchase a frame that bears very long top tubes, you will surpass the handle bars. This can prove to be a straining experience if you happen to be on an extended period of cycle rides. Therefore, the key is to choose frames that uphold shorter top tube lengths as per your cycle geometry.

Apart from this, the design of the cycle frame should be such that it is proportionate to your anatomic features. For instance, the ideal top-tube length for a person of (168-175) cm height should be (54-55) cm, thus signifying a medium-sized cycle. You cannot go on and buy a small-sized (51-53) cm top tube cycle if your height reaches about 180 cm, which would be an absolute debacle.

Don’t Forget the Desired Fit

After you have figured out the Material, Geometry & Length of the cycle frame, you will need to configure the fitness of the remaining parts of the cycle frame. Firstly, you would need to determine if the stem upon which the saddle is placed is proportional to your body. If not, modify it as you might fail to reach the pedals accordingly.

Secondly, you will need to work upon the positioning of your saddle itself. The fore and aft position as well as the way your saddle tilts need to be examined by mounting yourself on top of it. Last but not the least, the separation between brake levers and the angle between the handlebars will ensure your comfortable fit to the cycle frame.

How to Find Female-friendly Frames?

Not speaking in a discriminatory manner, female & male physique is innately different. Thus, female riders face a good amount of trouble while choosing the right cycle frames in proportion to their body. Nowadays unisex cycles are available, though at a lack of high functionality.

Unlike men, women have shorter torso length, but longer leg height. Therefore, being a female rider, you should opt for shorter top tubes. This would enable you to bring the handlebars in proximity to the saddle while also expanding your legs fully.


It might seem that availing necessary changes for your cycle frame would require running to and fro between shops. Fortunately, most influential cycle shops all around the USA render cycle adjustment services. With the information you now have, you’re only minutes away from renovating your brand new cycle.
