Price: $2300.00 at Rage Cycles
Overall Rating: 5 of 5
Value Rating: 5 of 5

Bike Setup:
Loaded Precision AMX 785mm bars, Loaded Precision AMX stem, ODI Rogue locking grips, ODI aluminum bar end plugs, MRP G2 chain guide/bash guard, Spike Spank pedals, 11-34T cassette.

Bottom Line:
Excellent value for a very competent downhill rocket. Ridable without modifcation, except maybe the bash guard issue (looks like the bike should have come with the MRP G2 according to online specs).

RMB took care of a warranty issue with the rear triangle very quickly. Thanks go to Rage Cycles in Scottsdale, AZ for handling it seamlessly.

It is difficult to give this bike anything less than 5 chilis. Even though it may not be 100% perfect for every rider as it sits, it is far too good for a rating of 4, and it makes an outstanding platform for an excellent DH rig no matter the skill level or terrain.

Strengths:
Fast, stable, predictable, burly build, well equipped right out of the box. The Boxxer fork and Vivid shock work very well. The I-beam seat is great. The two position direct mount stem (seems to be made by whomever makes the Loaded Precision AMX stem) appears to be well built and the adjustment is a good option.

Once the brake pads were bedded in they seem to stop the bike very well. The Avid Elixirs are not quite as nice as what I am used to (Hayes Stroker Ace) but still work well.

Pedals well considering what it is, just have to stay in the saddle. Changed the casstte to 11-34T to accomodate pedalling steeper inclines even better.

The Maxxis Minion DHF/DHR Super Tacky tires work well in typical AZ terrain, even though the 2.5s are really small.

Weaknesses:
The DT Swiss wheels seem like a lightweight choice for a DH bike. Mine came with a chain guide that did not have a bash guard. Changed that out before even riding it.

Likely as much personal preference as anything, but the stock bars are somewhat narrow for DH. Swapped them out for wider (31″ / 785mm) Load Precision AMX bars.

The Boxxer fork plastic covers at the bottom of the fork fell off and were lost on the first couple of runs. Not really a RM issue.

Rear derailleur cable seems to be prone to damage, moreso than other bikes I have taken down the same trails.

The RMB pedals are very low-end and literally began to crack into pieces after a dozen runs. Swapped out to Spank Spike, which are a great addition to the bike. Not a big deal since many bikes do not even come with pedals.

My bike did not come with the short cage rear derailleur which is what is on the RMB web site specs forthis year and model. There is no need for a medium cage and it just gets in the way. This will be replaced eventually with the correct short cage derailleur.

Similar Products Used:
