Description

XC Bib Short

We're sure we're not the only ones to do this, but we love Assos road bibs so much, we often run them under our mountain bike baggies. We've grown so accustomed to the fit and comfort that nothing else quite cuts it. If it's more of an XC day than a trail day, we'll forgo the baggy shorts, but we fear that crashing will trash our beloved bibs so we're grateful that Assos now offers the XC Bib Short giving us an excellent chamois and cut with the added durability to stand up to off-road use. It tested the shorts with BMC MTB Racing Team, helping to refine them into the tough, lightweight, and highly breathable shorts here.

First up, the short utilizes ripstop fabric on the side panels of the legs in the form of high abrasion resistant and breathable dyneRope material. It's a close-fitted woven fabric consisting of a black polyethylene weaving. Claimed to be the world’s strongest fiber, its 15-times stronger than steel while remaining extremely lightweight and able to wick moisture. Elsewhere, it uses its Type.429 Titanio fabric that’s engineered with 4-way stretch so they easily move with you.

Assos also took the opportunity to create a mountain bike-specific insert. Its positioned a tad more forward than on its road bibs and tuned for a slightly more upright mountain bike position and the increased body English required on steep switchback climbs. It uses a thick 10mm memory foam over an elastic insert to soak up the bumps over rough trails while reducing friction for increased comfort. The short benefits from Assos' goldenGate technology that interrupts the sewing in the area between the legs creating three-dimensional freedom of movement. Fewer seams mean reduced friction and more comfort. One of our favorite features of the s7 chamois is its perforated foam middle layer resulting in weight savings and increased breathability.

The shorts also utilize its aeroPatterningFenomeno1 design that consists of a patent-pending single seam that sits on the rear of the legs. This allows the main fabric of the short to wrap around your thighs giving more support and compression. For the uppers, Y7 frame carrier bibTech uses straps cut from wider elastic that sit with less pressure on your shoulders with each strap getting its bibStabilizer giving the straps sufficient support and prevent twisting while also serving as a holder for sunglasses.

A few last bits of tech that make the short a winner in off-road circles is its anti-bacterial odorControl treatment keeping the shorts feeling fresh and the mountain bike-specific leg grippers offering the ideal amount of compression without excessive pressure.

Long ride comfort

  • Familiarity: I've put it through the wringer

I was preparing for a long ride trail epic and my other shorts were uncomfortable after a few hours in the saddle. I chose these after reading reviews and wore them on a 4.5 hour Epic. Felt great right to the end of the ride and these have been my go to shorts ever since. Price is daunting and way more than the 100 that I usually pay for bibs and shorts, but I haven’t been disappointed. They’ve held up well. Things I like: pad comfort is outstanding, wide bib straps don’t feel like they are digging in, abrasion resistant side panels, and the low front end of the bib makes it easy to make a pit stop. Great shorts.

Best XC Shorts I’ve found

Just completed the Maah Daah Hey 100 in North Dakota. 107 miles and over 13k of climbing. I got these bibs in June and have put them through multiple training rides and the entire MDH100. These bibs are worth every penny! On shorter rides I’ll wear them under some trail shorts or by themselves on longer XC training days. They fit great and perform amazing. Just can’t say enough about this product.

Assos delivers on XC, love them

  • Familiarity: I've put it through the wringer

I just completed the Land Run 100 in these bibs. I have several Assos bibs and I must say they have outdone themselves on this one. I really liked that there is compression on the legs, the padding and comfort was so good I forgot I was wearing them. The straps were great and comfortable. I also like that I can tell that the used different materials in different areas and its should make them take some abuse for off-road. It was not an issue for my but it seems like they fit lower, at first it was odd because the bib seemed lower but the padding went higher. Not sure if that made sense. I highly recommend these bibs for long hauls. No regrets paying for Assos since the quality makes the difference.
