Road Bike Sizing Guide

Road bikes as the name implies are for road use. There are a growing number of “gravel” or “adventure” bikes which are based on road bicycles, but feature wider and more versatile tyres and disc brakes, so you can also do light trail riding such as towpaths. They are also more pothole resistant!

Sizing is normally in cm, and is a measurement from the centre of the chain-wheel axle (The BB or bottom bracket) and the top of the frame seat tube. Some are measured to the centre of the seat tube where it meets the top tube (otherwise known as the crossbar).

That measurement is on road bikes normally in CM – and no-one really knows why! Some road bikes will use “T-Shirt Sizing” so S, M, L, XL etc. but there will be a geometry chart that then shows the measurement in CM.

What is your height? Your suggested bicycle size

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
