Bike Test: B’Twin Triban 500 road bike

The B’Twin Triban 500 – a lot of road bike for not too much money
A road bike with a carbon fork typically costs more than £500. This B’Twin is £350. Cycle magazine¹s technical editor Richard Hallett weighs it up

It turns out £350 can buy you a lot of bike. In one way, that’s not surprising; much of the cost of a truly lightweight cycle can be attributed to the manufacturer’s efforts to lose mass, and the Triban 500 isn’t light.

It looks like it should be, with its carbon-fibre fork and a welded 6061 aluminium alloy frame “designed and tested in Flanders”, but nevertheless it’s a bit of a lump.

It’s well specified, however. Styling may be along the lines of a sports or racing cycle, with impressively profiled frame tubes and a sharply sloping top tube, but the Triban has threaded mounting points not only for a rear rack and full mudguards but a low-rider front rack to boot.

A budget road tourer or commuter, then? Why not, when there’s enough clearance for 25mm tyres with mudguards, when the frame is unquestionably sturdy enough for the task, and when the bike comes equipped with a triple chainset?

There are minor issues: bottom gear is high due to the small cassette, and the B’Twin ErgoFit saddle not quite ergo enough for long hours spent pedalling. Yet both are easily remedied.

Not so is one fundamental property of the frame’s design – steering that is quick to the point of being positively flighty. The straight-blade fork, made with 12K twill, sits at a steep angle, resulting in a highly sensitive front end that is anything but relaxing and cosseting.

Come to an accommodation with the steering and the bike is, in most respects, a tidy performer. The Microshift levers offer slick, accurate shifting, albeit via an unusual paddle arrangement that transmits the solid feel of an eight-speed derailleur. The B’Twin Sport dual-pivot calliper brakes are strong and controllable. The wheels are nicely true, and the overall finish good.

In short, £350 can buy you a serviceable bike, which needs just a small change to the head angle to be more than simply capable.


Flighty steering and somewhat heavy but robust, well finished, and well equipped. The Triban 500 has touring and commuting potential.
