Tom Bowers Cycling - I Built a Full Carbon AliExpress Gravel Bike for Under Β£1000!

Description

I set myself the challenge of building a full carbon gravel bike using only new pars parts, all for under Β£1000! And it wouldn't be one of my videos without sourcing most of it from AliExpress. From, the carbon frame and integrated bars to hydraulic disc brakes and tubeless wheels. In this video I walk through the full build, the problems I ran into (internal cable routing was a nightmare…), and what it looks like once it’s finally together.
The real question: is a Β£1000 AliExpress carbon gravel bike actually any good? Subscribe and stay tuned for Part 2, where I’ll take it out for its first proper test ride and reveal the final weight!

Here's the links to all the parts I used:
