If it is, it's a second comeback. My friends who rode trials when I was 17 were running front freewheels, and that was 6 years ago.
I used to ride trials from about 13-17. The front freewheel were only used on 20" bikes like Montys and Brisa's. I always rode 26" but my mate had a front freewheel. Jeans got caught in it all the time and you'd eat shit if you were going any speed or doing anything off an edge. We couldn't ever work out the advantage and generally the freewheels weren't ever peticularly great dealing with much pressure, Think eventually converted to fixed front and a Chris King hub on the rear. They make the best noise ever for a freewheel!
