2021 Commencal Clash 650b park bike wants you to venture out of bounds

Commencal’s Clash follows in the footsteps of the new Meta AM 29 and receives significant geometry and suspension kinematic updates for 2021 to boost its potential.

If you’re a bike park shredding, big-hit sending, gravity-fuelled two-wheel junkie, it’s likely you’ll have heard of Commencal’s 650b-wheeled Clash.

At first glance, the Clash occupies a niche corner of the market, but Commencal is trying to broaden its appeal by claiming it can pedal to the top of the hill and conquer enduro tracks as well as handle big sends in the park.

Although the outgoing model promised to do these things too, the new bike that replaces it looks like it has a good chance of nailing the Andorran brand’s goals of increased versatility.

2021 Commencal Clash updates

Although the Clash’s 2021 frame looks almost identical to the outgoing model, it has received an extensive overhaul despite the lack of obvious visual differences.

2021 Commencal Clash suspension updates

The keen-eyed among you will have noticed that the concentric axle and pivot of the old bike has moved up and forwards to now join the seatstays and chainstays just above the rear axle.

Its rear wheel is mounted to the chainstay and not the seatstay – as seen on Horst-link suspension bikes. This means the new 2021 Clash has a single pivot, linkage-driven suspension design.

The new Clash ups rear wheel travel by 5mm to 170mm and has a more linear suspension kinematic that Commencal claims should improve comfort on rough tracks and “ground feel” on steeper terrain.

Thanks to a flip chip on the front-most linkage pivot, the Clash has two settings: Sensitive and Dynamic.

Sensitive is designed for downhill and freeride-style tracks, where grip and comfort are important, and Dynamic is claimed to be better for smoother tracks or large jumps.

The Sensitive setting should be more linear, letting the bike use its travel more easily, while the Dynamic setting is more progressive, making the bike harder to bottom out.

2021 Commencal Clash geometry updates

Along with the suspension, the Clash’s geometry has been overhauled.

Commencal says it’s enhanced the uphill riding position by increasing the top-tube length and steepening the seat-tube angle.

Top tube figures across the sizes only increase by between 2mm and 5mm, but the seat-tube angle has increased from 75.5 degrees to 77.2 degrees (or 77.1 in a size XL) across the range.

But it’s the reach figure that’s really grown, which is most important when the rider is standing and the bike is pointed downhill. The 2021 size large Clash now has a 490mm reach, which is up by a whopping 23mm on the outgoing size large.

The head-tube angle has slackened to 64 degrees and the bike’s wheelbase has also grown – 1,265mm on the large – an increase caused entirely by the front centre getting longer.

The chainstays remain unchanged, at 434mm across the sizes.

Size Small Medium Large Extra-large
Seat tube angle (degrees) 77.2 77.2 77.2 77.1
Seat tube length (mm) 380 418 440 465
Head tube angle (degrees) 64 64 64 64.5
Head tube length (mm) 110 115 120 125
Wheelbase (mm) 1,216 1,238 1,265 1,292

Chainstay length (mm) 434 434 434 434
Reach (mm) 445 465 490 520

The Clash is also designed around shorter offset forks, a change driven by riders wanting calmer handling bikes.

Commencal claims the Clash is also built around shorter stems, needed to counter the growth in reach figures.

2021 Commencal Clash frame updates

The frame’s seen some updates, too. Although none of the changes drastically change its look, they should refine performance.

An updated rocker has let Commencal improve its finish and makes access to the shock easier.

The top of the seat tube has also been lowered, while the maximum insertion depth has been increased. This means longer travel dropper posts can be installed, so the seat is easier to get out of the way.
