I'm sorry, but I think you have so much "things" on your bikes! Bell, light, seatbag, reflex, bottlecage! I would have takes all those things of! In Norway we use to have light on the helmet/ head, reflex on the clothes and a backpack with drinking system. It looks so much cleaner, and the bike got lighter
I also think you have way too long stearer and many spacers
How many Kleins do you have? Do you collect or run a store? Is there still Kleins for sale in Asia? I saw Klein was still trading in Japan after it was closed down in Europe and USA.
