I’ve had two Slopestyle frames, both the earlier version and not the SS2.
I built the first one up with a double and bash and used to pedal it around quite happily. Wouldn’t say it was an all-day bike, but it was great for trail centre days. It weighed around 34lbs IIRC, so it was no lightweight. Fantastic on the downs though.
The second one I had I built up with a single chainring up front and used it for more downhill orientated riding. Could keep up fairly well with mates on DH bikes on most runs.
Never had any problems at all with mine, with the exception of the pivot bolts, which are prone to falling out if not secured with loctite.
Sold the last SS to buy a DH hill bike, which I’ve since sold on. Was on the look out for another Intense SS frame, but bought a Froggy 518 instead.
