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

Your 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; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With the goal of making sure that the Rockhopper offers both the best fit and best performance for every person, no matter their measure, Specialized have paired each frame size with the optimal wheel size.

Mountain Bike Sizing Guide

Mountain Bikes tend to use the T-Shirt sizing of S, M, L etc. or will have the seat tube measurement in INCHES. Why mountain bikes are inches and road bikes are CM who knows, but the part of the frame being measured is the same.

As a rule of thumb if you can identify your size as Medium on one brand, you should use that as a starting point on another brand too.

If you already own a medium mountain bike for example and are comfortable with the sizing, start there.
 

What is your height? Your suggested bicycle size
Feet/Inches Centimetres Suggested Size
4'10" - 5'2" 148cm - 158cm X-Small (14-15")
5'2" - 5'6" 158cm - 168cm Small (15.5-17")
5'6" - 5'10" 168cm - 178cm Medium (17.5-18")
5'10" - 6'1" 178cm - 185cm Large (18.5-20")
6'1" - 6'4" 185cm - 193cm X-Large (20.5-22")
