my new bike is going to be an orange frame with white rims (but won't be finished for ages cause i haven't got the money to buy all the parts at once) (starting on it in july) but white looks really good on a bike i would go for white mate hope this helps mate to decide your colours
they seem decent brakes mate i've heard good things about them i would go for it and i don't think they leek every brake has problems anyway hope this helps mate
i had the same problem with my stem, i ordered it and on the the website it siad it included top cap, and when it came there wasn't one. if is was you i wouldn't go near them again tarty bikes is 100% better
