Assos FI.Uno S5 Bib Shorts

    

Assos set out to develop an all-around racing and training bib short and what they produced was the FI.Uno S5. The focus is to provide a cyclist with a taste of Assos's legendary AEPD anatomic fit coupled with a comfortable chamois, high tech fabrics from Assos's Lugano labs with an eye on value. When you consider the time, effort and quality materials that went into this product, it is amazing that they arrive at their current price point. This performance orientated value bib is a best seller every season.

The FI.Uno bib shorts use the Assos proprietary A430 fabric panels throughout the body of the bibs. This magical fabric offers plenty of muscle compression and is super low volume. Being low volume and sheer, it offers plenty of ventilation and has great wicking capacity. These panels are all stitched together using over-locking seams provide a tight bond between panels and add elasticity. As with all Assos bibs, the rear mesh upper is one-piece for added support and completely breathable. The classic S5 chamois has the familiar klinik blue top sheet with dimples for air flow and heat management. The core of the S5 features multiple densities of material for supreme comfort.

The fit of the FI.Uno is decidedly Assos. This means all panels of the FI.Uno bibs are anatomically cut and when stitched together, form a perfect synergy called Advanced Ergonomic Pattern Design (AEPD II). Every panel is pattern-cut in an anatomical shape to mimic the body while in the cycling position. These bibs are made to fit perfectly while you are riding or in the cycling position, not standing around or sedentary.

We proudly offer the FI.Uno in multiple color ways and all sizes. Wash bag is included with every set of bibs.

Haven't been riding a whole lot but committed recently to the Rapha Festive 500 (500 k's Christmas eve to New Years). Today six and a half hours with Uno S5's and they were sensational. Struggled at 70ks plus for awhile with sore bum moving around a lot however settled down and had very comfortable return trip. Last 30-40ks I could feel the chamois padding like no other shorts I've had. Not to dis Castelli, Giordana, Pearl Izumi, Capo to name a few, but for long days in the saddle these are the go.

Pros: Comfort, fit, quality and value.

Cons: High back - can get hot even with the webbing.

Was a little skeptical about fit, because of the previous review. Turns out their sizing chart is accurate, no problem with fit. I guess you read reviews and take them with a grain of salt. More expensive than both Pearl and Castelli bibs I own, but far better fit and quality. The cahmois is simply superb.

Pros: Fit, comfort

Cons: none

Disappointing fit. This is my third pair of Assos bibs and it appears that the size Large is now 1/2 size larger than my other two pair of Assos bibs in size Large. I went into the local store and the size Medium is almost too small, but according to the sizing chart they should be too small and the size large should fit. Trying them on they felt fine, but after 1 hour on the ride they really started feeling large and not fitting well.

Pros: Nice look

Cons: Sizing is not consistent with past years

Phenomenal. Much better than any shorts I have tried from Pearl or Castelli, and overall, even better than the Rapha shorts I own. I have over 2 seasons and well over 3000 miles on these shorts, and there is not a single stitch loose. Ideal for longer (3 hour rides). Once you try these, you will never be willing to ride in anything else.

Pros: Best shorts money can buy

Cons: Price

This are awesome shorts which are decisively better than anything I have tried by other manufacturers (Castelli, Craft, DeMarchi, Girodana, Louis Garneau, Pearl Izumi, etc.). Personally, these shorts fit me better than the Mille, so I am happy to save the money. Assos is definitely designed for riding in Europe where temperatures are lower. On very hot days (90s F), I prefer Craft because they are much cooler and comfortable enough.

Pros: Long wearing, awesome chamois, great fit, cheaper

Cons: Still expensive, lack a version for very hot temps
