Summary
The Trek Slash is a high-performance enduro bike praised for its downhill speed, adjustable geometry, and capable suspension. It excels on technical terrain and wide-open sections, though some note its climbing could be improved. The bike's build and components are generally well-regarded, with specific mentions of its Fox X2 air shock and Bontrager Line Elite 30 wheels.
Premium, purpose-built race machine
Adjustable geometry via Mino Link
Capable on all technical terrain
Fox X2 air shock offers high- and low-speed adjustments
Impressive ride quality and durability of Bontrager Line Elite 30 wheels
Relatively short-travel 125-mil-drop post
Aluminum rims on a bike this expensive
Rear-wheel rub when riding steep roll-ins and technical chutes
Climbing could be improved
The Slash 29 embodies Trek’s conviction that 29-inch wheels are the fastest option for enduro racing.
The Slash is at its best when going downhill fast.
Both bikes are assuredly capable on technical and steep terrain, rolling majestically over bumps and tracking their lines.
Four piston brakes a must at the EWS.

Phenomenally stiff, impeccably controlled, hyper-fast enduro racer that’ll Slash your previous times. Buy if you want maximum speed and accuracy on the roughest, fastest trails
Superbly shaped, jaw-droppingly stiff full-carbon frameset
Ultra-sensitive, maximum grip but HD communicative and immaculately poised Fox suspension
Mostly excellent wheel, tyre and component pack
TALAS fork adds cost and drag
125mm Bontrager dropper is short and slow

No, this isn’t silly, it’s amazing! And especially available from the big manufacturers, it simply says that riders are pushing the boundaries of mountain biking and the technologies involved have made them a reality. Watch the video here. Take 160mm of travel and jam in a bike with 29″ wheels, and you’ll end up with a …

Trek Slash 29er carbon long term review on one of the best 29er on the mountain bike market. The 9.9 RSL edition is the top of the line Slash.

The new Trek Slash 29 sounds rock and roll and looks stunning, but does it go like a bat out of hell? When it’s time to go fast it gets the job done.
Great sizing and geometry.
Class-leading Fox suspension.
Takes Plus-size wheels.
Looks drop-dead gorgeous.
Could easily accommodate a 150mm dropper.
Stem lengths need to be shorter.
Bontrager SE4 tyres are fast rolling with good puncture resistance, but the level of grip doesn’t match the aggressive attitude of the Slash.

The Trek Slash is a true statement. It’s the company’s flagship enduro bike and it’s 29 inch. Only. In full team colours with a penthouse spec and race geo, this is an absolute stunner – the performance is likewise. There is a lot of thought gone into this frame. It’s based on the World Cup […]
