Hi fellas, I have read up a bit on switching gearing and noticed some of you have gone for the 14/48 etc. My bike came stock with 14/52 but a ride in some hilly rock single track has me pondering changing gearing. I was provided with a spare 13 front sprocket with the bike. The bike is plated but I only use it to connect trails and as a result, I am not interested in going overly fast on road. My question is, will the 13 tooth provide better engine braking going down steep rocky descents and do I need to swap chains? Has anyone tried this set up? The Freeride seemed to kick ass in this department!!. Thanks.
