Top Tips For Getting The Right Size

  1. Get measured before you order 
  2. Measure your chest and belly at its largest point 
  3. For road tops, if your belly is larger than your chest, you have a couple of options depending on how you prefer the fit of your jersey. If you don't want the garment to stretch at all, then use your belly measurement but this will be a baggy fit elsewhere. Otherwise go with your chest measurement but expect the garment to have to stretch to accommodate your belly. If you straddle 3 or more sizes, it's best to pick a size in the middle. Please email our sizing Guru's for more advice
  4. Our outdoor T shirts and MTB jerseys are a loose fit so check the half chest measurements in the product information and compare to your existing gear. Please note 2024 sizing may differ from previous fit  
  5. For road bottoms, if you are under 5'10" a smaller size will probably fit better. If you are over 6'4" a larger size may fit better.
  6. See product pages for specific advice and sizing
  7. Drop our sizing Guru's an email with your measurements if you need help
  8. Long sleeve underarm length *approx 61cm
  9. Jersey *approx length centre under collar to hem
  10. Sizes are approximate tolerance +/- 2cm
  11. When trying on adopt cycling position to see how the garment will feel when you are riding your bike
  12. As a rule, if between sizes it's usually better to go down a size for bottoms and for tops it depends whether you prefer a snugger or looser fit

Mens Road Bottoms, Shorts and Tights

If you are unsure of your size, particularly if you are an international customer email our sizing Guru's with your measurements and height before ordering.

A lot affects the fit of bibs - including height, build, thigh, bottom and chest size. The fabrics also stretch a lot so you could wear more than 1 size but the best fit will depend on your height and build as well as your waist and chest. 

If you are under 5'10" the smallest size is most likely going to fit the best. If you are 6'-6'3" the middle size will probably be the best fit. If you are over 6'3" or VERY Chunky, the larger size is probably your best option. If this doesn't make sense DON'T guess - email our sizing Guru's.

If you are between sizes it's usually best to go DOWN a size.

Mens Cracking Bottoms

As people carry their fat and muscle in different places the stretchy fabrics we use, combined with the design means that each short size can accommodate a variety of different body shapes and sizes.

We have used our FLAB sizing for road cycling gear to give existing customers an idea of how the shorts fit as well as a size chart.

For best results pick a size which best corresponds to your waist at its largest point (belly) and hip measurement. If you have chunky thighs and legs we suggest the larger of the sizes, if you have slim legs, you're probably better with the smaller size.

Available in 2 leg lengths = Short (32cm)* and Long (37cm)* leg length - *approx inseam from centre crotch seam and may vary upto +/-2cm

If you need help with a sizing suggestion drop our Guru's an email

Top Tips For Getting The Right Size

  1. Get measured before you order 
  2. Measure your bust, waist and hips at their largest part
  3. For bottoms, if you are under 5'6" a smaller size may fit better. If you are over 6' a larger size may fit better
  4. See product pages for specific advice and sizing
  5. If you are between sizes for our road bottoms, drop our sizing  Guru's an email with your measurements and height as all of this will affect the fit of the garment
  6. As a rule, if between sizes it's usually better to go down a size for bottoms and for tops it depends whether you prefer a snugger or looser fit 
  7. For road tops if you are between 2 sizes you have a couple of options, depending on your fit preference. If you don't want the garment to stretch at all, then go up a size, but this will be a looser fit elsewhere. Alternatively, pick the smaller size but this will have to stretch to accommodate your larger measurement. If you straddle 3 or more sizes, it's best to pick a size in the middle. Please email our sizing Guru's for more advice

Women's Road Bottoms, Shorts and Tights

If you are unsure of your size, particularly if you are an international customer email our sizing Guru's with your measurements and height before ordering.

A lot affects the fit of Lycra bottoms - including height, thigh, bottom and waist size. The fabrics also stretch a lot so you could wear more than 1 size but the best fit will depend on your height and build as well as your waist and hips. 

If you are between 2 sizes it's nearly always best to go down to the smaller size.

If your waist is larger than your hips when compared to our chart, you can usually go down 1 size on the waist without a problem and you may look like Olivia Newton John in Greece - ooh ooh ooh honey!

Sometimes people can go down 2 sizes but this isn't always comfy and can dig in depending on your shape. 

Our bibs are more generous on the waist because of the construction so this may be a more comfortable option.

Because our gear is tall, If you are under 5'6" a smaller size is most likely going to fit the best. If you need help just email our sizing Guru's.
