Compare the Rocket 520 to the leading 29er MTBs from Brand T or Brand S. While they charge for the name, we invest every dollar into your Shimano drivetrain and hydraulic braking power. Pure performance, no markups.

Why Rocket 520 is a Game-Changer:

  • Hydroformed X6 Aerospace Alloy: Featuring a Smooth-Weld finish and Internal Cable Routing. High-pressure liquid shaping ensures a frame that is vertically compliant yet laterally rigid, giving you carbon-fiber aesthetics with the legendary durability of X6 aluminum.
  • Full Shimano Altus 27-Speed Drivetrain: Massive gear range with the Shimano FC-MT210-3 2-Piece Integrated Alloy Crank—technology typically reserved for bikes twice this price.
  • Precision Hydraulic Stopping Power: Trust your safety to CSTAR Hydraulic Disc Brakes for one-finger modulation and consistent performance in mud, rain, or dust.
  • The 29-Inch Advantage: Alloy double-wall rims and 14G Stainless Steel spokes roll over obstacles that stop smaller wheels in their tracks.
  • Available Colors: Choose between a stealthy Matt Black or a premium Shiny Grey finish.

The jeans are a nice color, and length… they run SMALL… I wear a 33-34 and bought a 36. They were skin tight but breathable material… I sent them back to order a 38

I’m happy with the jeans
Size: 40, Color: Pink
I am very satisfied with this purchase. A lot of compliments too. They fit well, stretch to the material but the skinny fit look. The quality so far is great.

MOM-1, PANTS-1...well, I guess we both win
Size: 32, Color: Black
Purchased for my 17 yr old son, about 6'2, 180, medium built. PROS -Black pair is a nice happy medium between faded black and pitch dark. -Roomy around the waist, but not enough for children to sag (no, no, no,) -excellent price for quality of product CONS -might be too comfortable for wearer, resulting in an request for an abnormal amount of additional pairs -consistent compliments for wearer could cause inflated ego or confidence OVERALL I didn't hear any complaints from my son or "can you return this" which is a WIN for me, bc he's usually very picky. it's a whole thing with the length and the thickness, color, all of it. I thought these pants looked really nice, the color was casual enough for friends, and dressy enough for church. I was pleasantly surprised. Not a big fan of belts, but he is not comfortable with sagging (thank goodness), and the fit around the waist provided enough support to stay where they needed to. Pants also did not scrunch up at the bottom, and did not fit like capris. Product title described product to a T (or pants): slim fit stretch comfort casual classic solid- it was all of those in one!
