I have a 2009 Ltd Race hardtail – really pleased with it. I managed to pick it up before Cube hiked their prices due to the faltering exchange rate, so it only cost £900. I couldn't find anything else with anywhere near the spec for the money – Reba SL, SLX/XT drivetrain, light wheelset, Formula K18 brakes, etc. The only change I've made is to swap the old EA30 lo-rise bars (too narrow) for a Ritchey WCS Carbon Rizer. I also had to change the old EA30 stem due to a product recall by Easton, so took that opportunity to shorten what I thought was a bit of an excessive 120mm down to 100mm. As an added bonus, supply issues with the EA30 meant I ended up with a free upgrade to an EA50.
This year's model has been downspecced a bit, if I remember rightly – Deore cranks and perhaps one or two other subtle cost-cutting changes. They seem to have changed the ar*e-shredder of a saddle that came with mine, though, so it's not all bad.
I haven't weighed it, but it's plenty light enough for me. It's really responsive, MASSIVELY stiff and scarily fast. It has a pretty racey feel to it overall and can be a bit twitchy when the going gets steep and rough, but it's always handled everything I've been able to throw at it.
Definitely worth considering.
