Product Strengths:
Aesthetically (Its Looks): Amazing and the anodized finish is great on a mountain bike so one does not have to worry about paint chipping and little nicks that are always happening.
Rear suspension design- This bike has the stiffest rear suspension that I have felt in a four inch travel bike. I loved Chris Cocalis’ original creations, the Titus Racer-X and Moto Lite, but this bike is on a new level in comparison. This beefy rear suspension system allows a rider to really rail the bike in corners and ride much more aggressively than one would normally do on a four inch bike.
The rear suspension system used also allows the bike to stretch out/grip or grab the ground better from its dual pivot controls. This was the one of the best features that was noticed in comparison to the Titus, Racer-X. One can really climb and descend on this machine.
Direct Mount Front Deraileur- The Front derailleur mount used for this bike is also a plus as it creates one of the fastest and definitely the strongest shifting experiences on a mountain bike. The mount allows the derailleur a lot of backbone so that it gets its maximum potential because of the stiffness provided from the frame.
Integrated Bottom Bracket- The bottom bracket is stiff. It allows the bike to put out the most power possible with each pedal stroke and again help provide a nice solid base to the frame when turning and pushing down on the outward pedal.
Product Weaknesses:
Weight- If you are a weight weenie sorry but it’s on the heavy side. If the bike is being built for racing one might get frustrated with a bike that is 23-24lbs. This is about the average wight of our builds composed of Shimano XTR and Sram XO components, Stan’s No Tubes Wheelsets, and a lot of other expensive carbon/weight weenie junk.
However, if you think about the frame and how it comes with a front derailer, bottom bracket cups, and headset 6.14 lbs is not too heavy.

The Bottom Line:
The bike rips! It’s a 4inch bike on steroids… It can be ridden like a trail bike with its slack angles and fantastic suspension system.
