AliExpress has some SERIOUSLY colourful bike tech
Trace Velo

Most bike tech looks pretty boring, usually sticking with black and silver. However, AliExpress has become a fantastic place to grab some really colourful parts, colour-match your bike, and personalise your ride.
All the parts I’ve chosen for my road bike build are purple, but you can find the same bits in loads of different colours to suit your own bike. Whether you want to add a few subtle touches or go all-in with a full colour theme, these upgrades let you make your road bike truly unique.
On top of the looks, many of these AliExpress bike parts are lighter than standard components, giving you a little performance boost while keeping the price super affordable. It’s a great way to freshen up your setup, stand out from the crowd, or just have some fun experimenting without breaking the bank.
