Pro innovation

First seen back in 2009 when Castelli Cervelo TestTeam rider Jeremy Hunt rode the Omloop Het Nieuwsblad in knee warmers that he had cut to knee length. It took six years for it to catch on, but half a dozen or so riders started the 2015 Omloop with that same look. So Castelli engineered a fabric that lets them leave a soft raw edge at the back of the knee that won't cut into you. The women's version is technically identical to the men's version but incorporates their women's bib shape, women's Progetto X2 Air seat pad, and women's specific fit. Get ready for your most comfortable fall riding ever.

Who's Behind It?

Q. What do a 19th century Italian tailor, a designer for the Milan Ballet and the first ever lycra cycling shorts have in common?

A. They are all part of a rich 140 year history that's led to today's most recognised brand in cycling: Castelli.

Throw in a heart attack on a famous Italian climb, family feuds, Olympic gold medals and controversy in the pro peloton and it begins to sound more like a Sicilian soap opera than the backdrop to a cycling brand. But then again Castelli is no ordinary brand.

Today, Castelli's scorpion emblem is arguably the single most recognised in cycling. Iconic is an overused word these days, but the Castelli brand surely qualifies.

We first discovered Castelli on our year long ride through the Americas in 2010, when our founder Liz (pictured) wore Castelli shorts and loved them, so stocking them seemed an obvious choice. But we're almost as captivated by the story behind the name as the kit itself!
