Product description

Kids today have it so good. They’ve got lightweight mountain bikes with high-end tires, fine-tuned suspension, and modern geometry. There’s only one thing they’re missing: a real drivetrain.Super ShortReal Mountain Bike Drivetrain for 20" WheelsmicroSHIFT started with the DNA of their ADVENT mountain bike group. Then microSHIFT made every part smaller and easier to use. Lighter shifting, shorter reach, and more ground clearance, all with the same great chain retention, metal construction, and wide range. The shift levers sit closer to the handlebar, and the lever throw per shift is 43% shorter than the competition. No shifter is more dialed for small hands.Most derailleurs don’t fit 20〃 wheels, and the ones that do aren’t meant for real mountain biking. Super Short has the same clutch and metal construction as standard ADVENT and Acolyte groups, so the groms can ride as hard as they want without the chain falling off.To work better with small wheels and keep the ground clearance high, microSHIFT designed Super Short to work with an 11-38T cassette. When you pair that with a 20” wheels, you get a gear low enough to scale mountains.Included:- microSHIFT ADVENT Quick Trigger Pro Right Shifter 1×9 Speed Indicator x1pc- microSHIFT ADVENT Super Short 9 Speed 11-38T Cassette x1pc- microSHIFT ADVENT Super Short 9 Speed Cage Clutch Rear Derailleur x1pc - OEM package (This item is exactly as pictured and does not include retail package)

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
