i like my bike fairly light,im not the most powerfull of riders so i like my bike easy to through around so i choose lighter parts.i dont go over boared with the weight game,i have a double walled rear tyre,echo forged cranks and so forth .also having lighter parts means you can have heavyer parts elsewhere on you bike,where it would make sence too. true,when i had a 32mm rear rim i could only use half the pad material steve
