The new B'Twin Triban 520 and 540 are claimed to feature improved geometry, increased tyre clearance and better spec over the previous versions

Here at Cycling Weekly we are huge fans of the B’Twin Triban series, so we are excited to see Decathlon launch the bike in its latest iteration. The updated Triban will come in two drop bar models, the Triban 520 (£450) and Triban 540 (£600). The 520 is currently available on Decathlon’s website and features a full Shimano Sora groupset, aluminium frame and carbon fork.

The Triban 540 features the same aluminium frame and carbon fork as the 520, but with higher spec components. Shimano 105 10-speed shifters, 105 derailleurs and Mavic Aksium wheels, all for an astonishingly good value £600. Availability of the Triban 540 is expected to be mid June.

So what else is different from the previous Triban? B’Twin has updated the geometry on the new Triban 6061 aluminium frame and carbon fibre fork. The new frame features new tube profiles with a rounded square shape, and a larger down tube. With regard to geometry, the new Triban has been adjusted to greater meet the needs of those wanting to ride sportives or to use the bike for commuting, rather than racing.

Another big change from the previous models is tyre clearance, with the new Triban able to accept tyres up to 32mm. Each bike will come fitted with 25mm Hutchinson tyres and the capability to accept 28mm tyres in conjunction with mudguards and 32mm tyres without. With regards to mudguards the bikes feature eyelet so you can fit full proper guards. There are also eyelets for panniers.

The new frame has undergone significant testing on the cobbles of Roubaix and Flanders.

B’Twin have aimed to make the new frame versatile, with commuters, audax and sportive riders all in mind. On paper we are hugely impressed with this spec and look forward to getting our hands on the new Tribans to see how they stack up.
