The GRUS bib shorts are specifically designed for mountainbike marathon and gravel riding. The uneven terrain increases the risk of chafing, and the more upright position (compared to road cycling) demands other qualities of the bibs. We covered all this in the GRUS bibs and made them perfect for ”grus", which means gravel in Swedish. The Grus Bib shorts can be combined with any jersey, but matches best with the Grus Jersey or the Skarp Jersey.
