Greetings
Only really started cycling in earnest this year, mainly for commute but good fun aswell & I was wondering how I could go faster.
I have a standard Marin Kentfield and use the full gear range commuting but could do with more top speed. At times I am not rotating my legs fast enough to keep up and want to get round this.
I am innocently assuming I should look at getting a bigger cog on the crankset (?). The top one now has 48 teeth and I have seen racing bikes with 53.
As I said I need the lower gears for quite a fierce hill & so don't want to change that but if I look for a 53 teeth cog which fits is that the best thing to do and how much would I gain.
Your thoughts & abuse are welcome.
