Trek Fuel EX 9.9 XTR Mountain Bike 2021
The very epitome of a go-anywhere trail bike, Trek’s Fuel EX 9.9 XTR Mountain Bike has a full carbon frame with 130/140mm of terrain hugging suspension front and rear to keep the traction levels high and help retain control over rocks, roots and ruts. Both front and rear shock units use Kashima Coating for extra smoothness, with the FOX Factory 36 fork providing both plush travel and precise steering thanks to the larger stanchions. Trek’s Mino link within the rear suspension linkages can be switched over to lower the bottom bracket by 10mm and slacken the head angle by 1/2° for greater stability.
Braking and shifting are taken care of by Shimano’s premium XTR groupset which utilises the lightest and best performing materials and designs so that gear changes across the 12-speed cassette are instant even under extreme pressure, and with four pistons the hydraulic brakes are powerful enough to cope with the toughest, fastest descents. Size-specific Bontrager Line Pro 30 OCLV Mountain Carbon wheels help the bike maintain great handling and balance across the size range, with smaller frames using 27.5” wheels whilst the larger sizes have 29” wheels. Regardless of size, both the rims and the tyres are tubeless-ready so that conversion is simple.
The bike is finished using top-drawer Bontrager components, including a Line Pro OCLV Carbon handlebar and Line Elite Dropper seatpost.
