DONEGANS BICYCLE SIZING GUIDE
For online sales we advise customers to follow these guidelines 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.
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
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!
