It is good stuff but would I as a newer consumer upgrade with little knowledge on bikes (and no that is not intended as insult or an attack on anyone), probably not. I might consider it if I was buying a bike but your money is better spent on touch points like grips, pedals and a Kinekt seatpost that can transfer to other bikes. I would also use it for cycling clothing like gloves and helmets which are important for safety (and the gloves can help with comfort as well).

Upgrades are generally more expensive because you are buying single items whereas say Specialized or Trek or some other large bike company is buying thousands or more of those items so they are getting a better deal that they can pass on to you plus it comes with the bike built up by a shop so it is ready to go with all the support and warranties and you can just get out and ride. I am not saying one could or shouldn't upgrade certain bikes but the people who buy bikes to upgrade are overspending and there is just no need for that.
