Any possible upgrades?

Guys I'm building a project road bike can you guys please suggest any possible (budget) upgrades?

Frame: Brand-X RD01
Fork: Steel fork
Drivetrain: Shimano Tourney 2x7-speed 11-28 cassette, pro-wheel crankset
Wheels: Shimano Dura-ace C24 clincher
Brakes: Tektro caliper brakes with Aztec road system brake pads
Seatpost: alloy
Tyres: Continental GP 4 season

the tourney groupset will probably be one of the first things I'm gonna upgrade

Comments

  • brake pads (£5 or £10)
    brake calipers (make sure they are compatible with your shifters) - £20-£50 depending what you go for
    carbon fork (£50 or less)
    carbon seatpost (as above)
    tyres - depending where you ride you can use something more supple. I rarely find I get punctures so use Schwalbe Ultremo ZX and Michelin Pro 4 Service Course year round.

    If you upgrade groupset check the cassette will work with your wheels.

    What's wrong with the bike right now, anyway?
