Trek Roscoe 6 review - MBR

Aug 2022 · Alan Muldoon

Launched back in 2019, the Trek Roscoe 6 is definitely showing signs of ageing. Yes, it’s had a fresh lick of paint and some specification updates since then, the biggest change being the addition of a dropper seat post. Other than that though, it’s essentially the same bike that now costs £1k rather than £675. But is it good enough to be added to our best hardtail mountain bikes guide? Trek Roscoe 6 need to know: Massive 2.8in Kenada tyres on smaller 27.5in rims boost confidence and control The Trek Roscoe 6 gets a 130mm dropper post as standard Shimano Deore 10sp drivetrain and 11-46t cassette The wider 141mm Boost quick release dropouts provide extra tyre clearance But it’s not the jump in price or the front derailleur mount that instantly date the Roscoe 6. It’s the 27.5in wheels shod with voluminous 2.8in tyres. Every other bike in this category has made the switch to 29in wheels with narrower tyres, so has Trek simply backed the wrong horse? Frame Before we answer that question, let’s take a closer look at the frame. Manufactured from Trek’s Alpha Gold aluminium the Roscoe comes in six unique sizes, XS though to XXL. Dig into the number though and again the Roscoe looks dated with an elevated BB height and relatively steep head angle. It’s a good thing then that the generous reach and short chainstays have stood the test of time. Yes, the seat angle is a little too laid back to provide an optimum position for seated climbing, but it does open up the top tube measurement so the bike feels roomy in every other situation. Suspension Fatter tyres need fatter forks to provide the necessary clearance, so the Roscoe 6 comes with a SR Suntour XCM 32. It’s coil sprung and listed as having 120mm travel, but grease marks on the chrome steel upper tubes indicated that we never managed to get more than 100mm travel out of it. No bad thing, as the firm spring rate helped prop up the front end and maintain better overall geometry for shredding. The Suntour fork also has no rebound damping adjustment, so limiting its movement with a firmer spring is a crude, but effective way to maintain control. On the plus side, we welcomed the additional stiffness and security of the 15mm bolt-thru axle. Components Like Specialized, Trek has its contact points dialled. The Bontrager Arvada saddle is firm but comfy and we can’t emphasise enough how good it is not having to stop and fiddle with a dodgy quick release seat collar every five minutes. Yes, the action of the 130mm TranzX post feels a little crude, and it also adds at least half a kilo to the overall weight of the bike, but it’s worth it. The balloon-like 2.8in Kenda Havok tyres, and especially the fatter inner tubes, increase the overall weight too, so combined with the wider 35mm rims the Roscoe 6 weights in a portly 15.57kg, making it the …Continue reading »

Trek Roscoe 9 review

Feb 2022 · Daz Hall

As a gnarly trail shredding bike, it won’t surprise anyone that the Trek Roscoe is biased in favour of the rowdier type of riding.

  • Shimano Deore gears work well

  • Best frame protection on test

Lows
  • Wide tyres can feel vague and roll at high speeds

  • Weak brakes compared to others

  • TranzX dropper post was sticky

Trek Roscoe 9 review

Apr 2018

Trek's Roscoe 9 marries an aluminium frame with trail riding orientated geometry to chubby 2.8" Plus tyres on 27.5" rims. While it doesn't jam in as much value as direct sales rivals, it more than makes up for that with a fun, refined ride and coherent kit list.
