The Assos Tk.tiburu S7 knickers share the same chamois as the T.equipe shorts, but these are far more than a set of bib shorts with a few extra inches. The fabric is heavier than on those exemplary bibs, and has a slight waffle-like texture with a subtle nap to it. While not waterproof, light rain rolls of them. Like a lot of Assos products, when standing upright admiring yourself in the mirror the fit can be a little odd. In the case of these knickers, the BlasenSchutz front panel feels unnervingly like an undergarment, but is quickly forgotten about once you start riding.
At 6'1" and 160lbs, Assos' medium consistently fits me like a glove. However, compared to the T.equipe shorts in medium, the Tk.tiburu has a slightly more compressive fit. If you fall into the quad-zilla category and find yourself bumping up against the limits of a medium T.equipe, you might consider moving up to a large Tk.tiburu. Unfortunately, the trickiest issue with knickers and bibs comes down to fit; on top of all the usual dimensions that bibs are saddled with, any cycling clothing that falls below the knees also has a length consideration to balance. These knickers only fall about an inch below the knee-cap with my 34" inseam, which is about an inch or two less than I how I like to wear knee-warmers.
The Tk.tiburu is a great product, but as Assos charges a premium for their products, I feel it's only fair to review them with a critical eye. If these were just a tad longer I would happily give them an additional star.
