Are SB8's actually that good for street and park? They look more like xc tyres-I know a lot of urban riders swear by them though. How durable are they? The lugs are so small and short they look like they'd run out of grip pretty fast...
how long do the tabletops last for street? knowing specialized's current rhythms last practically forever, i'm tempted to lean towards their 2009 rhythm lites, which have a similar weight (600g), size (2.30) and tread pattern (check the 09 speccy article on bikeradar).
