Felt Doctrine 5 – 2019

Hard Tail - Hard Fun, Too

The Felt Doctrine 5 is the king the XC bikes for good reason: it’s a dang good bike. Based on the design of the old Felt Nine, the Doctrine 5 has been updated with a slacker head tube angle, better carbon, and a 1x11 drivetrain to be updated for modern sensibilities.

Its 69.5° head tube angle was slackened from previous models of the bike, which gives you the best control for heading downhill. Combine that with its steep seat tube angle of 73°, and what you get it a XC crusher that is amazing at peddling, but is also stable on the downhill, even in rocky sections. That balance of uphill and downhill is where this bike really shines. This is the same story on the wheelset and tires as well. The bike has 29” tires which give you truly awesome rolling capabilities but at a 2.2” wide tire. This means that pedal stokes are efficient, and you aren’t losing anything to splashy tires on the uphill.

Speaking of the uphill, this is where this bike really makes its money. This is one of the most versatile XC bikes in our shop not only because of the RockShox Recon SL shock smoothing out the bumps but because of its innovative carbon frame as well. Felt uses UHC Performance carbon fiber in the Doctrine 5, which means the entire package is stiff, lightweight, and fast. Every single pedal stroke is counted with no “bob” from the front end shocks, creating a swift and fun bike.


Felt Doctrine 5 - The Bottom Line

If cross-country riding is your game, then the Felt Doctrine 5 is hard to beat in terms of performance. Felt’s UHC Performance carbon frame is stiff and light, creating an efficient riding experience on the uphill. Each pedal stroke is efficient, with no power lost to bob or creak. Furthermore, the 29in, 2.2” tires give the bike create amazing rolling capability, both on the uphill and downhill. While descending, the RockShox Recon SL 100mm fork and slacker 69.5° results in a smooth and control bike, even at speed on bumpy terrain. If you want to get some miles under your belt, definitely check out this versatile and capable machine.
