I know the bike your talking about. That is what that frame is designed to run. That is why the bikes look right and will feel right. I know it doesn't seem like much, but 10mm in a shock can and does make a big difference (really its a bit more than 10mm too). You would need to source the remote reservoir model if you wanted to try the bigger shock. I have used fastace 12mm shaft shocks in 270mm with adjustable rebound and compression, and they are a great little shock IMO. (That is the shock I think that bike will come with unless they have downgraded it)
