Mountain bike shorts for commute I was recently given padded mountain bike shorts. Are mountain bike shorts good for commute? (around 11 km one-way)
Mountain bike shorts are ideal for commuting. If they fit, are comfortable and you like the look of them, you won't find a better commute short.  If you a fast rider, over 11km the extra drag of baggies will cost you a few seconds over a lycra skin suit.
However, if you are riding a road bike, you are breaking Rule #18 :)
