As I cycle a lot, I know how to repair or “tune” bikes. Sometimes my friends ask me how they can reduce the weight of their bikes. Then I respond with lighter parts, which are in general expensive. However, there are some brands which offer parts at a price which is relatively cheap compared to their weight. Thus I recommend specific parts which I can buy at my favourite webshop. Due to a lot of orders at this shop I am able to negotiate about the shipping costs and do not pay any most of the time. Thus I am able to order light parts at a relatively cheap price for my friends. Moreover I can assemble the parts on the bikes for free and my friends save the money which they would have to pay in a bike shop for assembling. Overall my friends can decrease the weight of their bikes with little money.
