Sizing data across cycling brands
The problem

Every brand fits differently.
Every order is a gamble.

Size chaos

Castelli L = Rapha M = Assos L. There's no universal standard across cycling brands.

Expensive returns

Buy two sizes, return one. Pay shipping both ways. Wait two weeks. Repeat for every new brand.

Size charts lie

Official charts say you're M. You order M. It doesn't fit. Because "M" means nothing without context.

No tool exists

True Fit works for fashion. Zero tools exist for cross-brand cycling apparel. Until now.

"A cycling Medium is less reliable than a psychic medium."

How it works

Your wardrobe is the data

01

Enter your kit

Tell us what cycling jerseys and bib shorts you own and how they fit. Castelli L runs tight? Rapha M bibs too long? Takes 2 minutes.

02

System finds patterns

We match your profile with riders who own similar kits. The more data, the smarter the recommendations get.

03

Get your size

"Go M in Assos — runs narrow in shoulders." Recommendations backed by real riders, not just size charts.

Sound familiar?

M

"Ordered a Castelli Perfetto in Large based on their chart. Couldn't zip it up. Their Large is like a Medium in every other brand."

Marcus, road cyclist
T

"I own jerseys in S, M and L across different brands. All fit me the same. Sizing is a complete joke."

Tom, cyclist & triathlete
R

"I just want to buy an Assos jersey without ordering two sizes and returning one. Is that too much to ask?"

Ryan, gravel rider
