Trek Slash 2021

10 Sep 2020


Trek have released the long-awaited 2021 version of their Slash model.


Prices for the 2021 Trek Slash start from a very reasonable £2650 for the Trek Slash 7, and for the real pros out there, go all the way up to £7500 for the Trek Slash 9.9. With most people reviewing the higher-end versions, we decided to look at the more affordable Trek Slash 7.


The Trek Slash 7 29er Mountain Bike is a high-value all-mountain ripper that’s built for shredding singletrack at full speed. It’s got a stout aluminium frame and capable suspension package that can smash through gnarly, choppy descents like nobody’s business.



It’s right for you if…

You’re an all-mountain rider who loves pinning steep descents and sketchy rock gardens. You want a bike that’s born to plough through the roughest stuff at full tilt, is fully capable of racing enduro, and doesn’t break the bank.


The tech you get

An aluminium frame built for harsh riding with a threaded bottom bracket, dual downtube guards, Knock Block 2.0 and 160 mm of travel with a RockShox Select+ shock and 170 mm Yari RC fork. Plus, a SRAM NX Eagle drive train and Line Comp 30 wheels that are already completely tubeless ready, including sealant.


The final word

It may be the most affordable Slash in the line-up, but don’t underestimate how fast it’ll carry you down the mountain. You get a frame built for day after day of hard riding with a no-nonsense parts package that leaves enough cash in your pocket for enduro entry fees or a lift ticket to party laps.
