Summary of Reviews

We have read all expert and user reviews on the Niner MCR 9 RDO. In summary, this is what cyclists think.

16 reasons to buy

  • The MCR 9 RDO is a gravel bike with excellent small bump compliance. It has a full suspension setup.
  • The cables are internally routed. This gives the bike a clean and polished appearance.
  • The long-wheelbase offers riders stability.
  • The rear suspension is outside of the frame's interior triangle. It doesn't interfere with space for a frame bag.
  • There is a remote lockout for the rear shock.
  • The bike minimizes fatigue on the lower back, wrists and hands, during long days in the saddle.
  • The dampening effect from the CVA linkage suspension allows riders to maintain their speed and cadence over washboard roads.
  • There is an integrated fender that protects the rear shock from getting dirty.
  • Testers were pleased that the seat post can easily be upgraded to a dropper post. This addition makes the bike an extremely capable descender.
  • Hydraulic disc brakes are very responsive.
  • Niner embellishes the frame with many mounting points for bags and gear.
  • The frame has room for three water bottles.
  • The aggressive geometry places riders in a position that makes steering quick and predictable.
  • The MCR 9 RDO can be used with 700c or 650b tires.
  • Wide tires allow riders greater comfort over gravel roads. The frame has clearance for 700 x 50cm or 650 x 54cm tires.
  • Testers found the bike handles extra weight from gear well.

4 reasons not to buy

  • Niner only offers the MCR 9 RDO in three sizes.
  • It’s easy to bottom out the suspension on trails.
  • Testers agree the bike is heavy.
  • The Fox fork limits the tire clearance to 40mm.

Bottom line

The Niner MCR 9 RDO is a full-suspension gravel bike. It floats over washboards and rough roads with 40mm of travel in the front and 50mm in the back. The CVA linkage of the rear shock is placed strategically so that it doesn’t interfere with a frame bag. The bike is capable of housing three water bottles in the frame. The bike is only available in three sizes. It’s heavier than other gravel bikes.

Niner MCR 9 RDO Full Suspension Gravel Bike Review

For starters the MCR (which stands for Magic Carpet Ride) has only half the suspension travel of even the raciest full-sus XC mountain bikes, but more importantly its geometry is that of a dedicated gravel slayer, which is nowhere near that of a modern MTB either.

Bike Test: Niner MCR

Niner’s CVA (Constantly Varying Arc) linkage design has been a main ingredient in their full-suspension mountain bikes for years, and for the MCR, they’ve tweaked the linkage to better respond to the high-frequency bumps of gravel riding versus the big hits of mountain biking.
