Trek Fuel EX 9.8 27.5in review - MBR

Sep 2014 · Danny Milner

A 27.5in Fuel EX joins the existing 29er, but the real story is a leap forward in suspension damping

Highs
  • The RE:aktiv rear shock combined with DRCV is a great combo — plush in descend mode while firm and supportive in climb, with an excellent mix of both in trail mode.

Lows
  • Long stems on the larger sizes seem at odds with the trail-orientated set-up.

Tested: Trek Fuel EX 9.8 29

Oct 2013

The EX performs brilliantly on everyday singletrack—the kind of trails you want to ride for hours upon hours. Its handling traits are balanced and nimble, thanks in part to its low bottom bracket and ample standover. The efficient DRCV suspension platform and the 27.5-pound weight make the EX 9.8 feel like a no-holds-barred race whippet while on the pedals.
