Bike test: Merida Scultura Endurance 300 road bike

Merida’s Scultura Endurance 300 is a good example of a modern ‘all-rounder’ road bike, complete with wider tyre compatibility and internally cabled, clean lines. It’s a sleek, alloy-framed equivalent of the ‘clubman’ road bike of yesteryear.

Frame and fork

Merida is a Taiwanese manufacturing giant that’s been building excellent alloy and carbon bikes for decades. The brand has never been shy of idiosyncratic innovation, and the finned ‘radiator’, heat-dissipating disc-brake mounts of the Scultura 300 definitely sit in that category.

Looking beyond acronyms and buzzwords, the triple-butted, pressure-shaped frame uses smoothed welds, blended stays and curved profiles to give a ‘carbon if you squint’ aesthetic. There are two bottle mounts, as well as discreet mudguard/rack mounts.

Merida says there’s space for 32mm tyres with mudguards and 35mm without. I think that’s over cautious – which is lucky as the 32mm Maxxis tyres it comes with actually measure 34.6mm.

Yet there’s still several millimetres between the tyre and the closest parts of the frame. There’s even more room in the full carbon fork, which also gets mudguard mounts.

There are two issues likely to cause consternation among long-distance riders. The first is Merida’s decision to feed brake and gear lines into the frame through the headset.

This keeps things tidy but means upper headset bearing replacement will require a disconnection of the controls. It also creates tight turns in the gear cables, which adds friction even when new.

The second issue is the PressFit bottom bracket. To be fair, interference-fit bottom bracket bearings seem to be more reliable now, and the wider shell does help give the Merida its generous tyre clearance.

But a threaded bottom bracket will always pose less risk of irreversible frame damage from a worn bearing or clumsy insertion. They’re easier to find spares for, too.

Ride

I found the sizing and shape of the Scultura excellent. The head tube is appropriately tall for comfort, without leaving you at the mercy of headwinds. The tapered fork steerer inside is stiff enough to escape the flex and vagueness that can plague a lot of endurance-category bikes on ‘sporting’ descents.

Merida has kept the handling angles sharp and the fork offset racy, so it feels responsive and able to make the most of the enhanced traction from the chubby tyres. You do need to actively pilot the Scultura more than a slacker, more stable bike, and this can be tiring as ride times or speeds increase.

You’ll also need to be wary of toe overlap if you’ve got larger-than-average feet, especially with mudguards.

Despite a weight over 10kg, and big tyres adding inertia, the Merida muscles up to speed well. Contrary to my experience of previous Maxxis road tyres, the big Detonator tyres roll easily. Just be sure to lower pressures to compensate for the volume or they’ll feel like concrete.

Clever sculpting of the hydroformed tubes, including the shallow-but-broad top tube and very slim stays, means less vibration through the frame. This is amplified by the compact frame layout, which provides lots of seatpost extension.

The CUES combined brake and shifter levers are lumpy where they meet the bar but not to the palm-bruising extent of previous, affordable Shimano designs. A 50-34 chainset and 11-39 cassette keep cadence reasonable, whether descending at warp speed or winching up a wall.

There is noticeably more lever throw for each shift compared to more expensive groupsets, and the KMC chain means shifts are fractionally slower. Hydraulic braking is firm and well communicated, with the wider footprint of the big tyres enabling you to brake harder on rougher surfaces without skidding.

Verdict

Merida’s Scultura Endurance 300 is a lot livelier and sporting than you might expect for a relatively upright, wider-tyred bike. It holds speed well, doesn’t drag obviously on climbs or descents and has enjoyable precision.

As long as you use appropriate tyre pressures (I settled on around 50psi) this doesn’t come at the expense of comfort. Mudguard mounts, a broad gear range and good tyre grip make it suited to longer rides in any weather.

For DIY bike maintainers, the positives on the road will be weighed against headset cable routing and PressFit bottom bracket concerns. Pricing is also slightly steeper than competitors from other mainstream, shop-sold brands.
