“Good Value, some great budget components, some junk”

The Good: Chain guide, tires, frame geometry

The Bad: seat, brakes

Overall Review:

I bought this because it's my third bike and I ride in two countries and needed one to use for about a month each year.

The good:

  • MRP chain guide works pretty flawlessly
  • Kenda K-rads are great tires
  • Frame geometry is great but chainstays could be shorter

The OK:

  • SRAM rear derailleur OK, but better if short cage
  • Crank works fine, square taper is reliable
  • Fork is bouncy and fun but has no adjust and bottoms and tops out really easily
  • Wheels are heavy and don't have sealed bearings, but are reliable
  • 710mm steel bar and short stem

The Bad:

  • Tektro brakes overheat on the slightest hill
  • Seat rails bend easily, seat is garbage
  • Frame cracked on seat post

Bargain basement bike, not bad for the money, can do it all. Don't expect much as this price point would suit a kid aged 14-16 really well.
