Attention parents! Are you looking for an all-around bike that will help your child build confidence on the up and shred on the down? One that won’t blow your budget in one sitting? Look no further than the 2019 Commencal Clash Jr. – one of the sickest kids bikes on the market to date.
This bike embodies everything a solid built kids bike should be. Touted as a “mini enduro” the Commencal Clash Jr. checks all the boxes with 27.5 wheels, a junior cockpit and frame, and 160 mm of rear travel with 160mm fork to balance it all out. Commencal has put a lot of thought into this build, specifically for kids that weigh maybe 80lbs wet. The suspension is purposely set at a higher ratio to counter for the weight of a lighter rider ripping down the mountain and tackling climbs.
Commencal bikes goes into its 20th year of production, and have taken the reins in offering well-built bikes for kids. Over the past few years, we have noticed a shift in the way bike companies market and build, specifically for the big kid/ tween sizes. Even just a few years ago, there were very limited options for this age group. Commencal bikes realized there was a missing link, and proceeded to design and built solid junior bikes to fill that void. Coming out gangbusters with their Jr. Cartel, and Commencal CoFactory riders, snapping up some of the best jr. riders world-wide to push their bikes to the max, they are now at the forefront of big kid/tween technology.
No Dealers, No Problem. You Buy Direct From Commencal.
Providing factory-direct pricing is yet another way this progressive company had made their mark on the industry. Offering brand-new, well – made bikes at a fraction of what you would find at your local bike shop. They also understand that kids grow, so to accommodate this – they have a “second hand” section right on their website, making it easier to keep it all in the family.
The bike’s linkage, absence of a front derailleur, and internal cable routing make the Commencal Clash Jr. an apt machine for enduro and gravity riders.
A 1 x 12 drive train slims down the equipment on the bars and allows the bike to save some ounces in the weight department.

Final Words On The Commencal Clash Jr.
My boys have both progressed insanely on the Commencal Clash Jr., as it has the strength, structure and sizing to accommodate their type and style of riding. They feel safe and stable in all aspects of climbing and riding the technical trails up in the PNW, the flow trails in Colorado and Whistler or desert and high alpine trail riding in our home state of Utah. Commencal is leaps-and-bounds ahead of the game on junior tech, creating “mini” versions of adult bikes. For kids that range in height from 4’7” – 4’11 the Clash Jr is the perfect fit. For smaller riders looking to progress, there is the Clash 20 and the Clash 24 – just miniaturized to accommodate smaller rippers.
