Curve Belgie Ti Disc first look

Campagnolo-equipped titanium and carbon dream-machine

Built up from a frameset over the past few months, this handsome Curve Belgie Ti Disc is finally ready to be put through its paces as my long-term test bike.

Several factors went into choosing the components, which I'll cover briefly below, with further discussion in my first ride review.

I wanted to create a do-it-all, dream-spec bike build with parts I had always lusted after.

Curve Belgie Ti Disc versatility

Named after a local group ride that Curve describes as "a multi-surface smashfest over cobbles, tracks and grassy knolls of Melbourne," the Curve Belgie Ti Disc is a bike aimed to perform in more than just one category.

Titanium is traditionally known for its comfort and endurance-focus as opposed to the stiff responsiveness of a carbon or alloy race frameset. However, when combined with aggressive geometry, a WorldTour level groupset and stiff carbon wheels, I think the bike will come alive to offer more than just one aspect of riding without the need to constantly change parts and fettle dependent on the riding focus of the day.

Curve says the frameset has been raced at everything from national road race championships and criteriums to ultra-endurance, trans-continental races and it is this range of riding styles that appealed to me.

While some of my more esteemed colleagues at BikeRadar embrace the changing of wheels, gearing and finishing kit for various types of riding, along with general fettling, I prefer to have a mere squeeze of the tyres ahead of a ride, clip-in and go.

As built, this Curve Belgie Ti Disc weighs 8.12kg. There are, of course, much lighter bikes out there, but this is by no means a heavyweight either. A 52/36 chainset and an 11-27 cassette mean it should climb comfortably in the hills and pick up the pace on the flats.

The frame and forks have a claimed tyre clearance of 32mm and I will look to experiment with this down the line. Currently, 28mm Veloflex Corsa clinchers (running at around 80psi) suit the spec of the build and wouldn't be out of place on cobbles or very light gravel and off-roading.

Built to last

Titanium frames have long had a reputation as being 'the last frame you'll ever buy', and while this might not be entirely true, I would certainly expect this frame to last years of riding through all seasons.

Disc brakes won six stages at this year's Tour de France, and while all of those were on Shimano groupsets, Campagnolo's disc brake offerings were raced on at the Tour de France for the first time this year.

The biggest appeal of disc brakes for me is being able to ride during the dirtiest and wettest winter days without slowly grinding away the brake track on your wheels. This also means that investing in expensive carbon wheels allows them to be used year-round as opposed to saving them for just sunny and dry occasions.

Curve makes both mechanical and electronic groupset versions of its frameset, with this mechanical version offering external gear cable routing and internal brake hose routing, resulting in a neat finish but with ease of maintenance or repair for any gear related issues.

Curve Belgie Ti Disc pricing and availability

The build of this Curve Belgie Ti Disc is undoubtedly a dream-spec finish and the prices certainly back this up. However, as a full build with slightly less exotic components, you could have an equally styled and versatile build for around two-thirds of this build cost.

A two-tone, brushed/polished finish on the Curve is the standard finish but the company offers custom paint options

  • Frameset (frame, Curve carbon fork, headset, Curve Ti seatpost, Curve Ti seat clamp and thru-axles): AUS$3,699 — approximately £2,345 / $3,050
  • Curve Belgie Ti Disc with Campagnolo H11 Super Record and Bora One 35 wheels (as photographed): AUS$12,250 — approximately £6,980/ $9,089

So the fork can be used again, when I return the frameset, I have left plenty of steerer — also allowing me plenty of adjustment as I get used to the bike
