Review: Castelli Nano Light Cycling Bibshorts

Review: Castelli Nano Light Cycling Bibshorts;

Time used, 11 months  RRP, £100

Purchased from Bike Chain Ricci

Castelli blurb 


  • Fantastic pad, very comfortable on those longer rides
  • The added warmth from a slightly longer (knee-length) leg
  • Very versatile garment, especially when combined with 3/4 leg warmers


  • Initially, the longer length felt odd

Main Findings

Apparently, not all cyclists like or wear lycra….

I find it hard to believe that anyone who rides does not like a bit of lycra, especially when it is as comfortable and functional as the Castelli Nano Light Cycling Bibshorts.

These shorts are an excellent addition to your autumn/spring wardrobe, saying that, I have worn them on warm summer days and been very comfortable. I have also worn them for most of my cyclo-cross racing and always been comfortable regardless of the weather.

The Castelli Nano Light Cycling Bibshorts are slightly longer than traditional bib shorts, ending just above the knee (rather than mid-thigh) giving a little extra warmth on the upper leg. At first, I found this a little uncomfortable, feeling slightly odd. However, after a few outings, I just felt the benefit of warmer legs. Add a pair of 3/4 leg warmers, and these shorts can take you way past autumn.

These shorts are designed for cool, wet spring rides and made from Nano Light Pro Fabric with minimal seams to minimise water entry. Castelli specifications suggest these shorts are suitable for temperatures between 10-20c.

The shorts are equipped with reflective logos, great for dull autumn/winter days, comfortable leg grippers and the Kiss Air seat pad, that apparently provides all-day comfort.

Currently, these are my ‘go to’ shorts. I have used them all summer, for most of my cross racing, under my baggy MTB shorts on colder days and for some of my longer rides. These are great shorts. If I could have only one pair of bib shorts, these would be my choice.
