Quantum 'Sundown' Bib Shorts


Quantum 'Sundown'

This kit is personal. Back in the 1990's Jonny acquired a stunning Klein Quantum and it immediately became the most coveted bike around the university campus. With it's airplane grade aluminium tubing and ridiculously cool fade paint scheme it was a breath of fresh, US air.

After years of Italian and French steel bikes dominating the bunch, the neo-punk styling and super-lightweight aluminium frame felt very different. Brash, anti-establishment and ridiculously fast, the Klein Quantum was the Andre Agassi of the bike world!

Quantum Sundown honours this 90's bike bling. Like our other Quantum designs inspired by the Klein, Quantum Sundown fades from pink to a deep indigo for a hint of chilled out, Californian dusk.

KOMRAID bib shorts are designed for the ultimate balance of comfort and performance.

We know that – perhaps more than any other item – bib shorts are a deeply personal piece of kit that can make or break a ride. They are the most important contact point with your bike. Any poor fit, chafing or rubbing will cause distress and irritation. They've got to look great and feel amazing, even after 5 hours in the mountains.

We tried dozens of different shorts and isolated the critical elements that go into a great pair. Through hundreds of hours of testing by us in training for sportive and IRONMAN events we have established a design that we’re happy to make available to you.

Using a nine-panel construction with flat lock stitching, together with a medium-density, anatomically-shaped endurance pad, KOMRAID bib shorts offer ultimate comfort.

We've used three different fabrics that quickly wick sweat away from the skin. In addition, the bib element utilises an open-mesh fabric to encourage ventilation.

The shorts are finished with wide, laser-cut, silicone-impregnated grippers that prevent the shorts riding up uncomfortably at the crotch and reduce pressure on the legs. This improves circulation, lessens fatigue and provides a great aero profile.

We know that judging the sizing of cycling clothing can be tricky. The key measurements of each size are given in the table below. We suggest you compare these measurements against clothing you already have to help you choose the right size for you.

IMPORTANT: Our clothing is ‘race fit’ and is designed to be worn skin tight for maximum aero benefit. If you are at the top end of a size range and/or want a more relaxed fit, we would advise that you go to the next size up.
