Giant SCR 2 Triple to compact
My trusty steed for the winter is 10 years old now. I've replaced most of it and now need tp replace the triple shimano Tiagra chainset and would like to swirch to a compact. I have switched all my components myself and would like to do this as well but have never changed a chainset before. Can I switch to a compact and if so what do I need to be aware of? Any advice would be gratefully received.
