Brent Robinsonwrote a review of Castelli Velocissimo Due Bib Shorts on September 10, 2012
Overall I love these bibs. The fit is great and the grip bands on the legs stay where they're supposed to (on a cheap pair of shorts I have the fabric will start bunching up around the leg after a few miles).
The only problem I have with these is they could use a little more padding. As others have stated, they are cut pretty low up front and if you plan on riding 35+ miles, your going to be uncomfortable.
I would defiantly recommend these to a recreational rider but I can't say the same if your one of these guys who do 100 plus miles on the weekends.
