New DirtySixer bikes Sizing: 2XL, 3XL, 4XL, 5XL!

Being tall and very tall, we are used to look for pants, shirts, jackets etc. in size with multiple X in it… Be it XL, XXL, XXXL, XXXXL or 2XL, 3XL, 4XL, 5XL etc. When I created the DirtySixer bikes, I didn’t want to follow the usual sizing designation, thinking it will give us a break on the abundance of X in the sizing designation. And, well, two years after, I realize it wasn’t that easy and that little stunt was actually making the understanding of how big the DirtySixer bikes are less simple, less direct. If we are use to look for something in our size and it’s usually XXXXL (4XL), then why your bicycle should be size M? The idea of being for the first time of our life on something sized M might have been fun, but for most, the meaning was lost even before they could get the info that a big bicycle at their size existed.

This is why for 2018 DirtySixer will change the sizing on the AllRoad, Road and MTB to be as following:

  • S become XXXL (3XL) for rider from 6’5” (195cm) to 6’8” (203cm).
  • M become XXXXL (4XL) for rider from 6’9” (205cm) to 7-f (213cm).
  • L become XXXXXL (5XL) for rider from 7’1” (215cm) to 7’4” (223cm).

This will help anyone having a better visual idea of how big our 36er bikes are and also let’s face it, when searching the web for a big bike, then the results will show the DirtySixer for those who typed “XXL bike” or “Mountain bike XXXL”.

Of course, a frame size will depend on other measurements (ratio femur/inseam and torso/legs) and we adapt the cranks length to your cycling inseam (well actually mostly your femur length).

Check out with the table below what size you will need to order for your 36er DirtySixer bike.
